What is the need for public awareness?
Eye cannot see what mind does not know? There is no subsitute for public awareness and participation. For wider,we have to spread the news of environmental problems and their impacts on plants,animals and human being..
What is the solution to pollution?
Some pollution will always result from man's and nature's activities . The secret is to get the levels down to the natural assimilative capacity of the Earth's ecosystems.
To this end people should follow all the rules from kindergarten:
- Pick up after themselves
- Don't take more than you need
- Clean-up the messes you make
- Don't wait for someone else to tell you to do the right thing
- Keep your neighbour's stuff as neatly as you want to have your'd kept
- Don't make promises you can't keep
And the rule from camping:
- Leave the campground a little cleaner than you found it
What will become of the animals if humans pollute the earth?
If humans continue to pollute the earth, animals will face habitat destruction, reduced food sources, pollution-related illnesses, and extinction. It will disrupt ecosystems and lead to a decline in biodiversity. Efforts to protect and preserve habitats and reduce pollution are crucial to ensure the well-being of animals.
What is precipitation that can carry pollutants into acquatic ecosystems?
Acid rain is precipitation that can carry pollutants into aquatic ecosystems. It forms when emissions of sulfur dioxide and nitrogen oxides from burning fossil fuels react with water vapor in the atmosphere to form sulfuric and nitric acids. When acid rain falls into rivers, lakes, and streams, it can lower the pH of the water, harming aquatic plants and animals.
How is ozone layer releted to air pollution?
The ozone layer is a protective layer in the Earth's atmosphere that helps protect us from the sun's harmful ultraviolet (UV) radiation. However, certain air pollutants, such as chlorofluorocarbons (CFCs) and other ozone-depleting substances, can break down ozone molecules leading to thinning of the ozone layer. This thinning allows more UV radiation to reach the Earth's surface, which can have harmful effects on human health and the environment.
Why does burning wood and burning fossil fuels produce similar pollutants?
Burning fossil fuels and burning wood produce similar pollutants because wood and fossil fuels are both consist of hydrogen and carbon. Carbon dioxide is produced when burning wood and fossil fuel.
What are the indicator organisms for fecal pollution in the US?
In the US, common indicator organisms for fecal pollution include fecal coliforms (Escherichia coli) and enterococci. These organisms are used to assess the overall quality of water sources, as their presence indicates potential fecal contamination and the possible presence of harmful pathogens. Monitoring their levels helps to determine the safety of recreational waters for activities like swimming and drinking.
What does radioactive pollution do?
We can identify sources that lead to radioactive pollution to the following:
* the use of depleted uranium in kinetic weapons * natural sources (radon from granite) * drywall
* coal burning * uranium mining * lost or stolen radioactive sources from industry or medical facilities
* nuclear weapon * transportation * disposal of nuclear waste * nuclear power plants The impact of radiation on human life is in addition to the immediately poisonous nature of some radioactive materials:
* Carcinogenicsis (causes cancers) * Mutigenesis (causes non cancerous changed at the cellular level) * Teratogenisis (causes changes to fetal development)
Pollution is anything which on being added to the environment changes the environment so that i is not able to support its normal ecosystems.
Heat can change the oxygen content of water, affect the number and species of fish, extract materials from sediments and encourage birds to overwinter.
These are negative changes to the environment caused by heat.
Heat is therefore a pollutong agent.
What chemicals does a rock quarry produce?
A rock quarry produces rock - gravel, cobble, pea gravel, stones, slabs, all grades and sizes of rock- as its products. None of these are commonly called chemicals.
In the way of waste there are some chemicals:
* Explosives residues * Anti-dust agents for loose rock (latex etc.) * Oils and greases from equipment. * Gaseous emissions - CO2, SOx, NOx (from fuels)
Production of greenhouse gasses?
The production of greenhouse gasses is harmful to the environment, causing an enhanced (or accelerated) greenhouse effect which is causing global warming. The gases emitted include methane and carbon dioxide.
What organism is being affected by littering?
Many organisms are affected by littering, especially marine animals like sea turtles, seabirds, and marine mammals. These animals can become entangled in litter or mistakenly ingest it, leading to injury or death. In terrestrial ecosystems, littering can harm animals by altering their habitat and food sources.
Many industries pollute lakes by dumping wastes, but just an ordanary person can pollute the earth. Just by dropping a candy rapper your setting an example for people to think its ok. But eventually that mess will pile up, as in the movie "Wall-E."
Of humans? Water, food, fresh air and shelter from extremes of temperature.
Yes, garbage can cause pollution when it is not disposed of properly. Improperly disposed garbage can release harmful chemicals and greenhouse gases into the environment, contaminating air, water, and soil. It is important to manage and dispose of garbage responsibly to reduce pollution.
True or false - non-renewable resources can never run out?
For the most part that is false. The major exception to this rule would be nuclear power. The fuel sources available for this form of power should last longer then the planet. That is not to say that there are not other issues involved with the use of this form of power.
What is transboundary pollution?
What Is Transboundary Pollution?
Transboundary pollution is the pollution that originates in one country but is able to cause damage in another country's environment, by crossing borders through pathways like water or air. Pollution can be transported across hundreds and even thousands of kilometers. The incredible distances that pollution can spread means that it is not contained within the boundaries of any single nation. This is why it is called 'Transboundary Pollution'. One of the problems with transboundary pollution is that can carry pollution away from a heavy emitter and deposit it onto a nation whose emissions are relatively low. Another problem with transboundary pollution relates to the quote above. Due to the fact that 'All things connect', the heavy pollution that is evident in the developed world also becomes evident in remote areas. For an example of how transboundary pollution becomes visible in a remote area like the Arctic, see the Arctic Haze fact sheet.
The droppings (guano) of Arctic Seabirds are another way that human made pollutants from the south arrive and concentrate in the Arctic. The levels of pollutants like mercury and DDT have been found to be as much as 60 times greater than those found at sites not influenced by seabirds. Since the guano is also an important source of fertilizer for the Arctic, many other forms of Arctic life centre around these areas in which contaminants become concentrated. This leads to the pollutants making their way into all levels of the Arctic food web. The seabirds acquire pollutants through contact with polluted ocean waters and food sources. These waters and food sources became themselves polluted through some of the mechanisms of transport mentioned above. In other words, the birds act as a taxi service for ocean borne pollutants to travel inland.
The laws are:
# Overall you end up with what you started with, but not as optimally arranged
# Left on their own things get worse # In the long run, you can never break even
In industrial processes you wan to make something out of another material. For this you need a supply of the original material and energy. You get some of what you want (product), other stuff you don't want (waste and byproducts) and energy degraded so it is of no further use to you.
The manufacturing systems are never perfect so you get less "good" than the ideal case would have you expect.
The waste and by products can be gaseous (carbon dioxide, SOx, NOx, fugitive VOCs), liquids (Heavy bunker oils, contaminated water etc.) or solids (sludges, fly ash, bottom ash, sediment). You also get energy waste - hot air and hot water. These components are lost to you forever.
Both the sewer pipe leaking and a company discharging liquid waste into a river are emitting water pollution.
The difference is that the sewage is composed of sanitary waste (feces and urine), pharmaceutical waste from medicines taken and disposed of in the building, and food waste from food preparation. The factory could be putting out a wide range of chemicals, acids, alkalis, heavy metals, complex organics and solvents.
How does pollution cause acid rain?
The pollution mixes with the rain clouds and makes it more acidic. Other human activities, such as driving cars, release nitrogen and sulfur compounds in the water vapor. This causes the water vapor to be more acidic. When the precipitation falls back to the Earth it is known as acid rain.
How is movement of matter and energy through an ecosystem different?
An example of the transfer of energy is the food chain. This is different from movement of basic elements in the ecosystem because energy gets used, not just moved.
The most severe forms of ocean pollution include oil spills, plastic pollution, and chemical waste discharge. These types of pollution can have devastating effects on marine life, ecosystems, and human health, making them critical issues that require urgent attention and action.
What kind of pollution do exhaust fumes and smoke create?
Exhaust fumes and smoke create air pollution, specifically contributing to the release of harmful substances such as carbon monoxide, nitrogen oxides, and particulate matter into the atmosphere. These pollutants can have negative health impacts on humans, animals, and the environment.
Which state has worst water pollution?
New York has the worst water pollution. The Hudson river is the biggest river there.This river is able to give about 40 million gallons per DAY!! This river is so polluted; however, the river is not healthy enough for people to drink. :(
