Why were the Air Jordan 1 shoes illegal in the NBA?

On October 18th, 1985, NBA commissioner David Stern banned the Air Jordan I sneaker from the NBA. He felt that they failed to meet on-court dress codes and did not match the uniform of the Chicago Bulls. Commissioner David Stern began fining Michael Jordan $5,000 every time he wore the Air Jordan I's on the court. Nike paid the fine and continued to have Michael wear the shoes. In doing so, the popularity of the product skyrocketed and sales were astronomical for the product.

How can air pollution be minimized?

More people using public transportation since that would make there be less cars on the road, reducing our carbon monoxide emissions. Also, more people could take a caravan (drive with others) to work for the same reason.

Other ways to reduce:

1. Reduce the use of cars --- Your car is a significant source of air pollution, so switching to a more gas-efficient vehicle will be a big help. Taking public transport to work rather than driving will reduces the number of carbon dioxide into the air.

2. Reduce Waste --- Manufacturing of unnecessary or disposable goods often produces air pollution, so reduced purchasing of disposables will help. In general, follow the solid waste mantra - "Reduce, Reuse, Repair, And Recycle" - and this will reduce air pollution as well from transporting, treating, or disposing of unnecessary wastes.

3. Eliminate Toxic Chemical Use at Home --- A surprising number of household or home shop chemicals are toxic and volatile. Many release vapors into the air, inside the home and out. This can be serious health threat to your family, and contributes to community-wide levels of air pollutants.

5. No Burn Barrels --- Northeast Wisconsin communities need to pass and enforce ordinances prohibiting individuals or businesses from burning trash in their back yards. This type of uncontrolled burning is extremely polluting, especially when many people are doing it. When trash is burned incompletely and at relatively low temperatures, a great deal of soot and ash is produced. Many plastics, coatings, inks, paints, metals and treated woods will produce toxic chemical air pollutants such as dioxin, lead, arsenic, chromium, etc.

6. Plant leafy trees and shrubs --- Deciduous trees and shrubs (the kinds that drop leaves in the fall) are excellent air filters to help reduce smog and cool the air on hot summer days.

Ozone Layer

What can we do to protect the ozone layer?

Since the banning of CFC in industry (Montreal Protocol, 1989), ozone depletion has mostly stopped with some signs that levels are increasing. Scientists believe that ozone will return to its pre-CFC level by about 2050.

Ways to Protect the Ozone Layer:
  1. Minimize high altitude aircraft flights (oxygen reduction and water vapor deposition)
  2. Minimize rocket flights (water vapor deposition)
  3. Encourage growth of plants that produce oxygen, discourage deforestation
  4. Decrease / control releases of high temperature steam / moisture to the atmosphere
  5. Eliminate production and release of known ozone depleting chemicals (such as CFCs and HCFCs) where remotely possible. Subsidize production of safer alternatives where possible.
  6. Establish controls to assure that new compounds to be used in high volume, are surveyed for effect on ozone.

Actions an Individual Can Take (see the link below for more):

  • Ensure technicians repairing your refrigerator or air conditioner recover and recycle the old CFCs so they are not released into the atmosphere.
  • Vehicle air conditioning units should regularly be checked for leaks.
  • Ask about converting your car to a substitute refrigerant if the a/c system needs major repair
  • Help start a refrigerant recovery and recycling program in your area if none already exists.
  • Replace halon fire extinguishers with alternatives (e.g. carbon dioxide or foam).
  • Suggest school activities to increase awareness of the problem and to initiate local action.

Various steps are being taken to avoid the ozone depletion. It includes the ban on ozone depleting chemicals most of them being CFCs.
There are various steps to control ozone depletion. The major of them being reduction of use of CFC's that is chlorofluorocarbons. These compounds are responsible for the depletion of ozone layer.

How bad is the air in Beijing?

Another point of view:

It is bad. China had a per capita carbon emission of about five tons in 2008, exceeding the world average of 4.18 tons per capita.

Older answers:

Data on the air quality in Beijing is difficult to come by and difficult to interpret when available. Factors such as the location of monitoring sites strongly impacts the perception of quality. However, the following external information may prove useful.

According to the European Space Agency, Beijing and its neighbouring north-east Chinese provinces have the planet's worst levels of nitrogen dioxide, which can cause fatal damage to the lungs. The Chinese independent environmental researchers list Beijing as No. 28 out of 113 on the Chinese list of polluted cities in China.

Beijing does not make the Top 10 list of polluted cities for particulate matter (Wikipedia data), or the Forbes Top 25 most polluted cities in the world (data prepared by Mercer Human Resources Consultants).

China itself is second on the list of carbon dioxide emitters in the world (Wikipedia data).

106 Tons of Carbon Dioxide per year:

  • United States: 2,795
  • China: 2,680
  • Russia: 661
  • India: 583
  • Japan: 415
  • Germany: 356
  • Australia: 300
  • South Africa: 232
  • United Kingdom: 212
  • South Korea: 185

It may be assumed that the majority of these emissions are related to heavily industrialized areas such as Beijing. There will be a burden of other pollutants with the carbon dioxide.

Municipal environmental departments in Beijing report deceases in SOx emissions of several percent in recent years.

Previous Answers
  • Not too bad.
  • Beijing air is just like that of New York or New Delhi.
  • Not true; their air is so bad you can't even see anything. The only reason they started to clean it was because of the 2008 Olympics event.

Since the 1980s, the city has experienced rapid industrial development, urbanization and increased traffic. Pollution from coal-fired power plants and emissions from slow-moving gas guzzlers have combined to cast a dun-colored haze over Beijing and its sprawling suburbs.

What planet is very hot due to its runaway greenhouse effect?

Venus, the second planet from the sun, is covered in clouds and has a very high surface temperature due to its greenhouse effect.

Due to an excess amount of carbon dioxide (CO2), its temperature is 460 degrees Celsius or 850 Fahrenheit or 735 Kelvin. It is the hottest planet.

It has a very thick atmosphere of Carbon dioxide that is considered a runaway greenhouse effect. Its average surface pressure due to the thick atmosphere is 93 bar, or 93 times that of Earth's. It is also the hottest planet.

The greenhouse effect occurs on every planet with an atmosphere (including Earth). On Venus, the runaway greenhouse effect is causing temperatures high enough to melt lead. Venus lost its oceans due to its greenhouse effect.

How much does it cost to run a 60 watt light bulb for 1 hour if electricity costs 10 cent per kilowatt-hour?

1 kilowatt-hour is 1000 watt-hours and 60 watt bulb consume during 1 hour 60 watt-hours of electricity, so then it costs 0.6 cent =>60/1000=0,06*price of 1 kilowatt-hour = 0.6 cent

What are we doing to protect animals?

We are recycling and not littering so trees don't need to be cut down. We can also give money so that animals and their habitats are protected. we also use waterproof sun lotion because if it wash's off, the chemicals will posion and kill the fish and plants. coral is also technically an animal and because it is so sensitive to changes to the surroundings you can't touch it or pollute the water in any way because your skin oils will kill it and the entire reef could die. The other ways by which we are helping them is by subduing poachers. animals like the bengal tiger are bieng poached everyday. they catch the tigers in man traps and either beat them to death or they pierce its mouth to kill it. the rich masterminds get tigerskins smuggled out of the country to be used as clothing, rugs,bedsheets etc.

Air Pollution
Plastics and Polymers

Why is dangerous to burn polymers?

It is dangerous because of the dangerous gases that form from polymers in the burning process. When polymers such as plastics are burned carbon containing gases are released. During the burning process, the carbon combines with oxygen present in the atmosphere & forms oxides of carbon.

These gases have been linked global warming, depletion of the ozone layer, acid rain,etc. They create harmful effects on our ecosystem.

It depends what type of polymer it is - if you're talking about polyethylene or polypropylene for example, the only gases you will generate are carbon dioxide and water vapour. These are not "dangerous" - yes, they are linked to climate change, but then you would get exactly the same gases by buring paper or wood.

How has technology affected car pollution?

It has radically reduced the emmissions given off from automobiles. Too bad the big vehicles aren't as closely scrutinized yet.

It is absolutly amazing. From a seminar recently, I understand that leaving the fuel cap off will release more hydrocarbons than from the exhaust out the tail pipe.

With the addition of flex fuel, electric, propane, hydrogen, bio-diesel, and Hybrid cars the outlook is better.

I have found that since the advent of OBDII the number of problems that can occur is astronomicle. I have a pre-OBDII and an OBDII vehicles,and by comparison (Both being Fords) the OBDII has suffered more problems (From very low MPG to extremely bad performance issues not able to be corrected by Ford engineers themselves). At any given time the dealerships claim it is in the computer program to which they can not change(Poor MAF sensor performance,Timing issues)they just don't seem very knowledgeable about what they are doing or care about the matter (You already bought it tough luck is the usual answer).But their resolve to the delema was to go online and purchase a chip for socket J2 on the computer,I asked if the vehicle does not get 21M.P.G. like the manufacturer states than to me there must be a problem. After the techs laughed they stated that there is no possible way for that vehicle with that program to attain that fuel economy.It was stated that 18 M.P.G was the best I'd ever see. Not accepting this from Ford I set out on a little adventure, and discovered their big flaw. It was the catalytic converters, and by having four of them would be a strain on any engine. So we decided to test our theory,and removed the larger segments of converters (2 of them). Created a filler pipe to cover the distance, and re-inserted the O2 sensor as to not throw a code. Discovery was the fuel economy went from 18 M.P.G. to 26 M.P.G. This was a very large jump in fuel economy. To test this out I had to do it several times on over the road tests, and the results came out to within a few tenths of a M.P.G. of each other. So, in removing the technology and applying some old fashioned know how we were able to make the vehicle perform better and be more economical than the manufacturer could. (And by the way Ford blames the E.P.A. for their bad designs). JIM

What environmental problems do pigs cause?

pigs amongst many farmed animals give off methane gas in there feces (manure) and methane is extremely good at trapping heat,it lets heat in from the sun but does not let it out. the pigs manure contains toxic compounds that seep into the water table witch is then in our tap water. how ever the manure is a good fertilizer and is full of phosphates and minerals that are good for vegetation.

If you have ever visited a pig sty or a pig farm and smelt that horrible odor well that is ammonia from feces and urine as well as hazardous viral and bacterial life forms all this seeps in to the ground into the water table and finds it way in to our drinking water sources. the C,F,C methane amongst one of them is all so highly flammable. cows are one of the worse polluters as they belch out enough methane in one day,just one cow,to fill 15x50 gallon oil drums per day so now imagine the whole worlds population doing that as well as pigs and other animals.

How is pollution related to acid rain?

it goes into the atmosphere and the clouds absorb it and if there is sulphur in the pollution it then mixes with the water in the clouds and rains it back down as acid rain

How does mining nickel ore cause pollution?

The machines companies use to mine the ore create polutive gases. There is likely a better answer and this one should not be taken seriously but it is an idea that spawns from your question and it can be researched and proven.

How does acid rains affect things on earth?

Acid rain is very harmful to the environment. Acid rain damages everything over a period of time because it makes the living things in the environment die. Acid rain affects the life in the water as well as the life on land. It is almost worse in water than on land because the fish that are in the water need the water to breathe. When the water gets polluted, then the fish get sick and end up dying.

All rainwater contains some level of acidity. Acidity is measured by pH, which stands for potential of hydrogen. The pH scale measures the amount of acid in a substance. PH is measured on a scale from 0-14, with 7 being neutral. The lower the number is on the pH scale, the more acidic that substance is. Normal rainwater has a pH of 5.6. When the pH level of rainwater goes below 5.6, it is considered acid rain.

Air Pollution

Why is pollution a problem in Mexico City?

Overpopulation, irresponsible consumer habits and geography create a "perfect storm" in Mexico City that allows air pollution to be the problem it is there.

The city sits in a valley surrounded by mountains. Smog from manufacturing and chemical plants as well as vehicle exhaust fumes get trapped by the surrounding mountains due to lack of any powerful-enough winds. This makes up the layer of gloom that sits over the valley due to a "cook-pot effect".

This smog can cause burning in the eyes and throat of visitors not used to it within a few days, especially in those with sensitivities to pollutants.

Air Pollution

What is acid mine drainage caused by?

Sulfide ore still in the mine reacting with ground water and air from the tunnel/shaft/pit producing sulfuric acid. [e.g. 2 ZnS + 2 H2O + 3 O2 --> 2 Zn + 2 H2SO4] This acid mixes into the ground water and either drains from or accumulates in the mine. When it accumulates in the mine it can enter the aquifer, contaminating wells and springs supplied by the aquifer.

How does air pollution affect precipitation?

Particles in the air can serve as nuclei of condensation hence favoring precipitation.

Differently sized particles rest at different altitudes, according to vertical pressure gradient. For this reason the term 'air pollution' is not accurate enough for it does not specify the kind of polluting particles. For a particle to be able to act as nucleus of condensation it has to be of considerable size: dust.

Often the main pollutants being monitored (but that cannot serve as nuclei of condesation since they only are of molecular size) are NOx species, such as NO or NO2.

Also ozone O3 is considered an air pollutant, since ozone is not supposed to be found in the biosphere. NOx and O3 can cause irritation of lungs and airways, worsening pre-existing breathing problems, such as ashma. Old people and persons affected by breathing difficulties are advised to stay indoors when levels of NOx and O3 rise.


concentration of NOx and O3 is largely driven by upper-atmosphere chemistry, driven by photodissociation reactions (hence solar light). For this reason periodic changes of concentration of these pollutants are recorded in winter and summer, according to different solar exposure.

Global Warming

Does watching TV cause global warming?

Home use is responsible for more than half of the total output of carbon dioxide. Appliances (A/C, heat, water heaters) account for 70% of home electricity use, and another 10% by incandescent lighting. Televisions actually account for about 3% of the typical home's energy use.

Pinpointing television use as a significant cause of global warming is therefore contraindicated.

What will happen if global warming continues?

Many things can happen if Global Warming continues:

  • Heat waves and the resulting deaths
  • Loss of crops and the resulting famines
  • Glaciers and the ice caps of Greenland and Antarctica melting and the resulting flooding of coastal lands, cities, and low-lying countries
  • Increased and more savage storm activity, especially coastal storms, high tides, and storm surges with the resulting threats of salt-water flooding of croplands and erosion
  • Loss of habitat for all kinds of bird, insect, marine, and animal life, including man, with the resulting need to move, adapt, or die.

Countries will get warmer and many areas now used for growing crops will become desert. Sea levels will rise and many low lying areas will be flooded. Millions of people all over the world will become refugees, desperately seeking new homes and new lands where they can have food and water.


The IPCC 2007 syntheses report projects a number of both positive and negative impacts associated with climate change and sea level rise. These are summarized in the "IPCC Impacts of Climate Change" link in the related links section.

  • Many island nations, such as Bangladesh and other continental low lying areas will be inundated by a rising sea, displacing millions of people, and creating a global refugee crisis.
  • Disruptions to climatic systems like the thermohaline circulation (ocean currents) may cause cooling and drying in some locations. For example, the Gulf Stream which keeps Europe warm and habitable may stop, as has happened in the past, resulting in a return of now balmy European climate to something similar to Siberia.
  • An advance of tropical diseases into higher latitudes. Diseases like malaria are spread by warm loving mosquitoes, which can migrate further in a warmer climate, and may result in world wide pandemics.
  • Acidification of the oceans associated with increases CO2 in the atmosphere may result in a massive die off of fish and other marine life, resulting in global ecological collapse and massive depletion of crucial food stocks.
  • Agricultural land which now grows crops will become desert, forcing millions of people to seek food elsewhere.
  • Sources of water for agricultural and domestic use will dry up.
  • The economies of many countries will collapse.

What is factory fumes?

Nitrous Oxides (NO, NO2 and N2O), Sulphur Dioxide, Carbon Dioxide and Carbon Monoxide are the famous ones, depending on the reactions that are taking place in the factory. There are also particulates (PM10) which are small cinders which end up floating around the atmosphere.

However many factories have special grilles inside their chimneys to remove the sulphur dioxide, or they crush the coal mixed with an acid to remove any sulphur, thus reducing the amount of SO2 in the atmosphere.
