Identify two forms of global pollution?
noise pollution and air pollution
Noise pollution is excessive, displeasing human, animal or machine-created environmental noise that disrupts the activity or balance of human or animal life. The word noise comes from the Latin word nauseas, meaning seasickness.
The source of most outdoor noise worldwide is mainly construction and transportation systems, including motor vehicle noise, aircraft noise and rail noise.[1][2] Poor urban planning may give rise to noise pollution, since side-by-side industrial and residential buildings can result in noise pollution in the residential area.
Indoor and outdoor noise pollution sources include car alarms, emergency service sirens, mechanical equipment, fireworks, compressed air horns, groundskeeping equipment, barking dogs, appliances, lighting hum, audio entertainment systems, electric megaphones and loud people.
Air pollution is a release into the atmosphere of any substances, ex. chemicals or airborne particles, which are harmful both to the human and animal health as well as the health of the wider environment.
Atmospheric pollution occurs because the release of air pollutants takes place at a rate much faster than they can be accommodated by the environment and removed from the atmosphere without causing serious harm.
Pollution had been known to exist for centuries, but it became an issue of serious concern only in the last 200 years or so, mostly due to the industrial revolution.
Atmospheric pollution originates from all the parts of the world and travels around knowing no borders.
Air pollution' is the introduction of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or cause damage to the natural environment or built environment, into the atmosphere.
The atmosphere is a complex dynamic natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earth's ecosystems.
Indoor air pollution and urban air quality are listed as two of the world's worst pollution problems in the 2008 Blacksmith Institute World's Worst Polluted Places report.
Roll up your sleeves if you really expect to gain an overview of this broad and stunningly under published topic. We live our lives in a world that is many times more radioactive than it ever was naturally. The sources of nuclear pollution (uncontrolled radioactive material) were initially confined to bomb tests, but with the advancement of our understanding of the things we can do with radionuclides, we began to produce them by the tonne. Production means contaminated waste. What a headache.
Reactor accidents have contributed to increased background radiation. Big time. How many square miles of land do we just have to walk away from never to return before we get it? The monuments to our foolishness stand for all (or no one) to see: the apartment buildings, stores and shops as well as the houses of whole communities sitting empty. The parks and playgrounds desolate. And all of it contaminated.
But there are small accidents that occur regularly where a nuclear excursion (such a polite term) results in the release of some radioactivity as well as injury or death. What many are unaware of is the number of shipments of radioactive materials that occur by common carrier every day. This huge shipping slate means accidents can occur (have occurred) that result(ed) in the release of small quantities of radioactive elements. And that doesn't include the large sources that get loose around the countryside here.
In the breakdown of the USSR, many tonnes of nuclear materials went missing. Some frightening portions were weapons grade fissionable material. But there are many sources (source: a bulk quantity of radioactive material that was produced to act as a portable generator for radiation energy) that got away. Highly radioactive materials are unknowingly being stripped and recycled as scrap. Over there, and even over here, too.
We need to get up to speed on this stuff. All of it. And we need to spool up quick. There are two serious problems with radiation: it's seriously dangerous (and for a long time in many cases), and it's invisible. The latter makes it easier to ignore. Working around the stuff can get you dead in seconds. And you may not even know it until after the fact. Dramatic, but true.
Radiation due to uncontrolled radioactive waste and other unconfined radioactive material is a growing threat. It quietly adds its contribution to cancers and the genetic damage we as a people suffer from. Radiation is all around us. It sits in dim corners. It flows in our waters. It rides the currents of air all over the globe. It does so unfelt. Unheard. Unseen. And we sleep very well at night without thinking about it.
Do the experts exaggerate global warming?
No. The risk is that by trying to hard too avoid criticism, scientific experts are failing in their duty to inform us fully of the facts and potential consequences of global warming.
It is really because of the debate generated by non-experts who would deny some of the consequences of global warming, that some gain the impression that the 'middle ground' is in the middle - hence that the experts must be in some way exaggerating.
A:
It could be that those scientists are prostituting their professional integrity to continue receiving funding from proponents of a One World Government that hopes to gain political control by manufacturing the global warming crisis. Thirty years ago, the same groups were warning us of the coming ice age.
What happens if you drink acid rain?
normal rain in England is acid rain so if you drink it, it wouldn't kill you you may be ill for a few days but it depends on were about you live near a factory in the country side near a busy road all fumes go up into the atmosphere to create acid rain! MKK448 edited this
What are the signs of global warming?
- climate change, extreme weather events.
- the melting of the polar ice caps
- sea level rising
- Pacific Island countries under water
- Glaciers retreating
- rising temperatures
- ski resorts closed
- animal species extinct
- climate refugees moving countries
- people in poor countries dying of starvation
- melting of polar ice caps
- rise in temperature
- floods
Orthophosphates are the most common form of inorganic phosphate found in water and are essential for various biological processes, such as DNA synthesis and energy production in cells. They can also contribute to water pollution when found in excess amounts, leading to issues such as algal blooms in aquatic environments.
Harmful gases in the atmosphere?
Some of the harmful gases which are rising in the atmosphere and are major cause of atmospheric pollution are (in no particular order):
- Carbon monoxide (from incomplete combustion of fuels... no choice, toxic to breathe),
- Sulfur dioxide and nitrogen oxide (from industrial and vehicular exhaust, causes of acid rain, irritates air passages),
- Chlorofluorocarbons (CFCs, refrigerant discharges, causes destruction of the ozone layer),
- Mercury emissions (from industries, fluorescent lamps and the burning of coal, potentially toxic),
- Carbon dioxide (fossil fuel burning and greenhouse gas),
- Methane gas (cow farming, landfill emissions and natural sources, greenhouse gas),
- Volatile organic compounds (from fuel vapors, solvent, paint, etc. Really includes methane too),
- Ozone (which is bad at low altitudes and does not survive to replenish the high altitude ozone layer which protects us from UV light)
See the Web Links for more information.
Why do we have global warming?
We have global warming because of deforestation and fossil fuels (coal, oil and natural gas).
When we discovered coal, and how powerful it was in driving steam engines, we were delighted. This was 300 years ago, and we didn't realise then that the carbon dioxide (CO2) from the burning coal would be too much for the carbon cycle to remove.
We didn't realise that by cutting down the forests all over the world this would mean that more carbon dioxide would be left in the atmosphere.
We didn't understand then, about the greenhouse effect, and that greenhouse gases building up in the air capture more and more of the sun's heat.
Now we understand, but governments and people won't make the hard decisions to save our children and grandchildren from a hot and dangerous future!
(The hard decisions are, of course, to change from fossil fuel to renewable energy, and to replant thousands of forests!)
How is Carbon dioxide a greenhouse gas?
The greenhouse effect keeps the earth warm by preventing all the sun's heat escaping back out into space. Carbon dioxide is one of several "greenhouse gases" that help in this. Carbon dioxide captures some of this radiated heat and keeps it in the atmosphere. Some other greenhouse gases are water vapor, methane, nitrous oxide, and CFCs. In fact, any gas with three or more atoms acts as a greenhouse gas.
Other greenhouse gases:
Shortwave energy (that emitted by the sun) passes through the atmosphere pretty much unimpeded, ultimately to be intercepted by the ground. The warm ground emits longwave radiation in proportion to the fourth power of its temperature. In a completely dry, CO2-less and ozone-less atmosphere, this upwelling longwave radiation would all be lost to space. Carbon dioxide absorbs upwelling long wave radiation and re-emits it back to the ground, thereby reducing the amount of heat that escapes to space, warming the planet. The warmer planet evaporates more water, and the water vapor absorbs even more longwave radiation than the carbon dioxide, warming the planet even more.
Incoming solar radiation is widely distributed across the electromagnetic spectrum. Some wavelengths (mostly visible light) get through the atmosphere to the surface, some don't. Of the radiation that gets through, some is reflected and some is absorbed by the surface of the earth. The reflected radiation is not an issue, because it goes right back into space at the same wavelengths that it came in at, unimpeded, just like on the way in. It is only the absorbed radiation that is a problem. This radiation is later re-emitted, but in the form of Infrared Radiation (IR).
Certain atmospheric gases, known as "greenhouse gases", including carbon dioxide, absorb IR, then re-emit it back into the atmosphere. Some percentage of this re-emitted IR (after a long sequence of re-absorptions and re-emissions by other greenhouse gas molecules) eventually works its way back down to the lower atmosphere and is said to "warm" the surface. This is the "greenhouse effect". The "greenhouse effect", in and of itself, is a completely natural thing, and also a very goodthing. Without it, the surface would be far too cold for life as we know it to exist.
Greenhouse gases absorb, then re-emit the IR, in a completely random direction. It could go up, down, sideways, or any direction in between. Re-absorption by other greenhouse gas molecules complicates the path and destination of an individual unit of IR, but what it all boils down to is that something less than half of the IR absorbed by greenhouse gases eventually finds its way back to the surface, with the remainder escaping into space.
How can we slow or stop global warming?
You CANNOT stop ClimateChang nor Global warming and Cooling.
The Earth throughout geological history has heated up and cooled down. There are at least three known Ice Ages. ; Coldclimate, with intervening warmer periods.
This all happened before before motor cars and industry; even before mankind was on Earth.
So something else is driving the system.
The Earth is a very dynamic system, it is NOT an inert 'lump of rock' floating around the Sun.
It is known theEarth's core is hot, there by drives the mantle to convect, and in turn makes the tectonic plates move and the ocean's warm/cool. These will affect the climate. Also affecting the climate is the Earth's axial angle currently ~ 23 degrees and reducing to about 21 o , but will expand to ~ 28 o. Also or orbital track about the Sun is not circular but and ellipsoid, an ellipse that does does not quite close up, but shifts a little each year.
Also this ellipitcal movement ranges from near circular to a narrow ellipse.
All this occurs over a period of thousands of years, but will have an effect on the climate. Also the Sun is at one of the foci of the ellipse, not the centre. All this is a natural dynamic , which obeys Newton's Laws of Universal Dynamics, which man has no control over, but will affect the climate.
However, We can do something about making the atmosphere cleaner; less cars and industry emitting CO2 etc.,s gases.
Yes, it's very real!
The industries threatened by global warming are spending tens of millions of dollars on disinformation campaigns to make us believe that man is not causing the climate to warm up. Science historian Naomi Oreskes has done an excellent job of documenting the fact that there has been a continuous scientific consensus in anthropogenic global warming (man is causing the climate to heat up) since 1979. The American Geophysical Union recently did a survey of scientists on this topic. They found that 97% of climate scientists who are actively doing research on the climate all believe that man is causing global warming. Global warming is very, very real.
A closely related phenomenon could end up killing us all. Recent research has shown that 3 of the five mass extinctions in earth's history has been caused when the oceans have gone anoxic (oxygen deprived) and hydrogen sulfide producing anaerobic bacteria has released hydrogen sulfide into the atmosphere killing most forms of plant and animal life. These events have happened when the C02 concentration in the atmosphere reached about 1000 ppm. We are currently at 400 ppm and this is increasing by 3.5 ppm per year -- and the rate of increase in increasing.
What are the sources of carbon monoxide?
Carbon monoxide is a by-product of combustion, present whenever fuel is burned without enough air (oxygen). It is produced by common home appliances, such as gas or oil furnaces, gas refrigerators, gas clothes dryers, gas ranges, gas water heaters or space heaters, fireplaces, charcoal grills, and wood burning stoves. Fumes from automobiles and gas-powered lawn mowers may also contain carbon monoxide and can enter a home through walls or doorways if an engine is left running in an attached garage. Other sources include fire places, industrial processes, cigars, smoldering fires, etc.
Fortunately the CO combusts if it reaches another part of the combustion zone if the temperature is still high enough and there is sufficient oxygen.
Note: With cigars and cigarettes the CO produced is inhaled by the smoker and combines with the smoker's blood to form carboxyhemoglobin. This emoves the CO from second hand smoke.
A religion entails belief in a supernatural controlling power, especially a God or gods entitled to obedience and worship. There are those who with excessive zeal promote action to stop global warming, as well as those who, again with excessive zeal, deny its reality or our ability to do anything about it. However, excessive zeal on either side does not constitute religion.
________________________________
Sometimes it seems so. Any religion is based on unprovable beliefs, and religious people have faith that their beliefs are true. "Faith" implies a lack of PROOF; if you had proof, you wouldn't need faith. Further, most religions differentiate between good actions, and "sin" - where "sin" is described as "evil actions".
Many of the claims of global warming lack any real scientific basis, and most do require an element of faith - belief without proof - by their supporters. People who do not accept the claims of "global warming" are frequently denounced as "evil", and as "environmental sinners". Given that "sin" cannot exist without a religious belief, many global warming advocates do act in distinctly "religious" ways.
The writings of any religion are not subject to question or scrutiny by the faithful, and this is certainly the case with the canons of global warming. Any attempt to verify the claims, to examine the fundamental data, or to question the proclamations of the priests are strenuously opposed.
How does acid rain affect rocks?
Rainwater contains carbonic acid, and chemically reacts with rocks, particularly carbonate ones, dissolving them slowly.
As sulphur and other gases (most commonly found as byproducts of industrial activities) diffuse into clouds, the overall acidity of the rainwater will increase. In small amount this is not a real problem, but when the amounts begin to increase you can get problems such as acid rain. As rainwater is naturally acidic the effects of pure rainwater on rocks will be the same as those with acid rain (although the rate of acid decay of the rock will be higher with acid rain). The effects of the acid rain are most noticeable on limestone (as it is very susceptible to acid erosion due to its high carbon content). The acid will corrode the surface of the rock, allowing to be more easily dissolved into the water and carried away. Over time this can cause serious problems to the overall structure of the rock. If acid rain affects buildings then the outer walls will often be checked to ensure that they will still be able to help support the building.
As a percentage of overall carbon dioxide output how much are cars responsible for?
CO2 from a car is produced by a chemical reaction on the fuel in the engine. Carbon enters the car via the fuel, with each atom of carbon attached to (about) two atoms of hydrogen. When the carbon leaves via the exhaust, each atom is attached to two atoms of oxygen.
The chemical action of producing the CO2 also produces the heat energy that creates pressure and pushes the pistons to propel the car.
So one pound of fuel produces about 3¼ pounds of CO2. The extra mass comes from oxygen taken in through the car's air filter.
A car that travels 12,000 miles per year uses 300-400 gallons of fuel, weighing 2000-3000 pounds, therefore the CO2 is 6000-8000 pounds, or 3 to 4 tons.
What moral difference if any does it make who is dumping why they are?
From a moral perspective, the act of dumping waste is generally considered wrong regardless of who is doing it and why. It is important to dispose of waste properly to protect the environment and human health. However, the intentions behind the act of dumping may impact how society views the perpetrator and the severity of consequences they face.
Is global warming the beginning of the end for life on Earth?
It has not yet been confirmed but it could cause apocalyptic natural disasters, such as gigantic floods.
Any number of possible scenarios could bring about the end of mankind, and possibly all other life on earth. Global warming is one scenario. Others include: large asteroid impact; global thermonuclear war; global pandemic virus; overpopulation and resulting lack of resources; multiple supervolcano eruptions. While all these are possibilities the odds vary from one scenario to another. Even if mankind survives into the far future, billions of years hence, they would still be faced with the inevitable death of the universe.
How much greenhouse gases are being emitted yearly?
Carbon Dioxide emissions:
Human respiration (breathing): 2 BMT (Billion Metric Tons)
Domesticated animals respiration: 6 BMT
Wild Animal (excluding Insects) respiration: 4 BMT
Burning of fossil fuels in Internal Combustion Engines (cars, etc): 16 BMT
Burning of fossil fuels to Generate Electricity: 9 BMT
Other Human-Industrial CO2 emissions: 1 BMT
********************************************************
Insect Respiration: 48 BMT
********************************************************
That's right, insects produce nearly twice as much carbon dioxide as all humans industrial emissions.
By the way, I don't have the figures handy, but all of the above is a DROP IN THE BUCKET compared to what the OCEANS emit. But as much as they emit, they absorb even more.
Also, contrary to popular belief, rain forests do not CONSUME carbon dioxide, at least not in net terms. Yes, they consume quite a bit of CO2, but if the trees are not harvested, they will die and rot, releasing all of their stored carbon back into the atmosphere to combine with oxygen and form CO2.
In terms of REAL CO2 generation. Our Oceans emit between 90 and 107 GTonnes of CO2 annually. This represents 97% of all CO2 produced. This number is nothing though, in comparison to the annual volume of the real greenhouse gas. Water Vapor, which represents up to 80% of all forcing and 99% of all gas emitted annually.
The most recent figures are that the burning of fossil fuels, mainly for electricity generation, smelting and transport, emits over 30 billion tonnes of carbon dioxide each year, and rising. This is "new" carbon dioxide, which actually adds to the atmospheric concentration of carbon dioxide, unlike almost all other sources which are part of the natural carbon cycle and do not add anything to the atmospheric concentration of carbon dioxide.
Is global warming caused by humans and their activities?
Humans are a major contributor to global warming, many of our actions from producing raw materials such as steel and electricity, manufacturing road vehicles, ships and aircraft, refrigerators, televisions (this list is endless) to transporting goods and people around the world, encouraging cows to produce milk (by product methane) and even incinerating our waste, all have a detrimental effect on our world.
The burning of fossil fuels alone accounts for over 30 billion tons of CO2 emitted into the atmosphere each year. While natural greenhouse gas concentrations DO fluctuate, the steady measured rise since the onset of the industrial revolution is primarily caused by burning fossil fuel. In 1700 CO2 levels were 280 ppm. By 1900 they had risen to 290 ppm, increasing by an astonishing 1.5% per century. CO2 has not changed this rapidly in geologic history.
Within four years CO2 will exceed 400 ppm. Virtually all of this 25% increase is attributable to human activity.
At the present rate, atmospheric CO2 concentrations will exceed 500 ppm before 2050. Many of the world's climatologists consider 350 ppm to be the maximum sustainable level, though even 350 ppm is 20% higher than CO2 has ever been throughout human existence, prior to the 1980s.
A:Although global warming may be caused by human's greenhouse gasses, there is surprisingly little evidence for this.Firstly, humans emit surprisingly few greenhouse gasses compared to the rest of the Earth. Most of the greenhouse gasses (something like 60-70%) come out of the oceans. A lot (like 30%) comes from things on land breathing. Very little (around 3%) comes from human pollutants (such as factories).
Secondly, there is not much evidence that CO2 is the cause of global warming. Although both CO2 and global temperatures are both rising now, this has never happened before in the Earth's history. Most of the time, it's just the opposite, when CO2 is up, temperature is down.
Lastly, global warming is happening on other planets, so the Sun as a cause is a very serious contender. Mars' ice caps are melting and Jupiter is having storms even more violent than usual.
A:It is the solar radiation that is ABSORBED by the earth that is, supposedly, a problem. This absorbed sunlight is later re-emitted in the form of infrared radiation. Carbon dioxide and other so-called "greenhouse gasses" (the most important of which, by far, is water vapor, by the way) in the atmosphere then absorb this re-emitted (not reflected) infrared radiation, causing the atmosphere to warm. This is the greenhouse effect, and it was happening for billions of years before the first internal combustion engine was invented, and without it, the Earth would be far too cold for humans to have evolved. The theory of anthropogenic global warming has it that EXCESS CO2, from the burning of fossil fuels, has created an "enhanced" greenhouse effect, causing the atmosphere to warm well above some "optimal" temperature, whatever that might be - no one seems to be able to state what the optimal temperature is. (But this theory is wrong, because CO2 absorbs only a small range of wavelengths of infrared, about 10-15% of all IR radiation, and even in that small range, it has to COMPETE with water vapor to absorb the IR. So, as it turns out, between the water vapor and the CO2 that was already in the atmosphere long before the industrial revolution, all of the available IR radiation was already being absorbed. So, it doesn't matter how much CO2 is in the atmosphere - there's only so much IR that is going to be absorbed by CO2, and we were at that level of IR absorption long before the industrial revolution.) Also, what you call "pollution" is, in fact, carbon dioxide. Without CO2, there would be no greenhouse effect, nor any human life on Earth. CO2 is a vital nutrient to all plants. Since when did we start calling a substance that is so clearly and vitally important to life, a "pollutant"? True, we might have more than we NEED at the moment, but the trees certainly aren't complaining. They're lovin' it. A:This really is the disputed issue. It is very clear from the geological evidence that periods of global warming and ice ages do occur. What is perhaps less clear is whether or not industrialization and other human activities are accelerating the earth's natural processes. Evidence linking carbon dioxide to periods of warming do suggest that our appetite for fossil fuels is adding to the already present natural processes. A:There is essentially no disagreement among accredited climate scientists that global climate change is caused primarily by human activity. A:There are many accredited climate scientists who dispute the theory of anthropogenic global warming. Richard Lindzen, Timothy Ball, Robert Balling, Roy Spencer, Bill Gray, Marcel Leroux, Fred Singer, Reid Bryson, and William Kininmonth are a few of the more famous ones. Others, like David Legates, George Kukla, Tim Patterson, John Christy, and William Cotton, while acknowledging the possibility that human activity influences climate change, either say human influence is minor compared to the natural forces causing temperatures to increase, or insist that we do not know enough about the climate to say, with certainty, that mankind is causing warming. And there are dozens of prominent scientists in other fields related to the issue that have weighed in on the skeptic side of the issue. A: Firstly, humans emit surprisingly few greenhouse gasses compared to the rest of the Earth. Most of the greenhouse gasses (something like 60-70%) come out of the oceans. A lot (like 30%) comes from things on land breathing. Very little (around 3%) comes from human pollutants (such as factories).Secondly, there is not much empirical evidence that CO2 is the cause of global warming. Though CO2 and temperature do appear to be strongly correlated over at least the last half-million years, it has always been temperatures going up first, followed (hundreds of years later) by CO2. So, if there is a cause-and-effect relationship at all between the two, clearly, increases in temperature cause increases in CO2, not the other way around, as global warming alarmists claim.
Lastly, global warming is happening on other planets, so the Sun as a cause is a very serious contender. Mars' ice caps are melting and Jupiter is having storms even more violent than usual. Also blame the sientest who created the greenhouses they are known as haters of nature. :(
Yes! There is some debate over whether global warming was started naturally, and it might have been, but humans have made it worse and worse. For example, the more carbon dioxide in our aptmosphere, the higher the temperature, causing global warming. And, of course, humans are the ones producing all the carbon dioxide by using cars, etc.
A:This is a tentative topic, and many scientists disagree on it. Some say that we are amidst a natural warming and cooling process of the Earth, and others say that the green-house gases we are releasing are causing the sudden warming. We have undoubtedly sped up the process by our actions, and there is more supporting evidence and data that suggests that humans are a main cause of global warming. A:The primary cause of global warming is man's burning of fossil fuels (coal, oil and natural gas) in industry, transport and to generate electricity. All these human processes release extra carbon dioxide (CO2) which has been hidden away for millions of years. This extra CO2 is disrupting the natural carbon cycle which has kept the planet at a comfortable temperature for as long as life has existed. This extra CO2 is causing the enhanced, or accelerated greenhouse effect in the atmosphere. A:Just some facts: If one looks at the estimated temperatures of the world since its beginning, one will observe a constant cycle of heating and cooling. So "global warming" is true in that the earth is currently warming up, as it has been since the end of the "Little Ice Age" hundreds of years ago. However, this is not caused by humans. In fact, the amount of greenhouse gasses, mainly CO2, that mankind generates, is negligible compared to the amount naturally generated by the environment. Even IF mankind produced enough CO2 to make a difference, that in itself doesn't even matter, as scientists and astrophysicists, looking at graphs of the Earth's estimated heat compared to estimated CO2 levels over thousands of years, found that the Earth's heat rises an average of 600 years BEFORE CO2 levels rise, indicating that rising CO2 levels are, in fact, TRIGGERED BY THE SUN'S INCREASED HEAT. One logically concludes that the driving force behind the whole cycle is the Sun, and greenhouse gas levels respond to the amount of heat given off by the sun. The observed rise in greenhouse gasses is the RESULT of the warming, NOT the cause.To add on to my previous answer, the oceans contain 37,400 billion tons (GT) of suspended carbon, land biomass has 2000-3000 GT. The atmosphere contains 720 billion tons of CO2 and humans contribute only 6 GT additional load on this balance. In closing, a small shift in the balance between oceans and air would cause a CO2 much more severe rise than anything we could produce.
No, acid cannot hurt you directly. In other words, acid rain won't burn your skin or make lake/river water dangerous to swim in.
However, acid rain can certainly hurt people indirectly because it can affect the quality of our environment, which has a big impact on us. For instance, acid rain can have a detrimental effect on forests and trees as well as the soil. If we as humans depend on these resources to support our livelihood, then acid rain can hurt us very badly. It causes skin irritations,burns etc

Using muriatic acid to clean masonry is an approved technique, but caution must be exercised. The muriatic acid , even as runoff, is harmful to delicate tissues and any plants in the area. If there is runoff, use lime to neutralize the acid.
Perhaps you could be unique from all of the other alarmists out there, and show an accurate graphical that shows the REAL picture: On a graph, (the graph will need to be the length of a football field to be accurate) show the breakdown of ALL of the components of the atmosphere. At the END of the graph, show the TOTAL carbon dioxide that is in the atmosphere today. 360 Parts Per Million (PPM) will be shown as a little over an inch of TOTAL carbon dioxide on your graph, if you decide to do it accurately. The CHANGE in carbon dioxide over the last hundred years has been about 50 PPM, or on your graph it would be a little less than 1/4 inches. Then to be truly accurate, and to fully disclose the importance of the carbon dioxide increase, show that not only has this not been the HIGHEST level of carbon dioxide that the earth has experienced, the phase that the earth is going through currently is one of the COOLEST periods on record, which has lasted for a couple thousand years. Earth is ACTUALLY returning to a more typical temperature level. There are some who truly believe in the global warming theories, but unfortunately there are so many true scientists who would tell you otherwise, but are afraid to speak out for fear of the consequences they would suffer. "Global Warming" is a political issue. If you'll bother to look any further than the emotional content, you'll find that there is nothing really of substance to the global warming movement. It's all smoke and mirrors and a lot of rhetoric. That's ok, I'm sure you have your firm beliefs and won't bother to listen to anything that I have to say. So have a good concert. But to answer your question, one of the major costs of the concert would be THE TRUTH. You would need to be willing to ignore the truth if you were to put on a concert like that.
What does it mean to cap greenhouse-gas emissions?
To cap means to stop, to put a cap on something. If an industry is producing greenhouse gas, then the government will legislate a cap, meaning it will only be allowed to produce this much greenhouse gas. "Capping greenhouse gas emissions" is the point at which greenhouse gas emissions stop. Each year the cap will be lowered so greenhouse gas emissions will start to decline.
Why is producer gas called producer gas?
Producer gas is called so because it is produced by the partial combustion of solid fuel, usually coal. The gas is generated in a device called a gas producer or gasifier. The term "producer" refers to the fact that the gas is produced during this process.
