Air pollution during Olympics.
It is going to be the worst problem during Olympics.
One of the quickest ways you can cut back on air pollution is to drive your car less, or ask your parents to drive less and use less polluting alternatives like busing, walking, or bicycling whenever possible. The less we pollute, the easier it is for Earth's natural systems to clear the air and water. Of course there are as many solutions to pollution problems as there are sources of pollution. One very common solution is to put some kind of filter at the source - like "smoke-stack scrubbers" at electric power plants, or catalytic converters on your car. One of the greatest air-pollution success stories is the ban on lead in gasoline. By taking lead out of gasoline, less lead is spewed into the air, and average levels of lead in children's blood have been steadily falling since the ban went into effect.
The problem of global climate change is linked to the accumulation of gases, including carbon dioxide and methane, in the atmosphere. Scientists have disagreed over the net effect of this pollution on the global climate: some have argued that it produces global warming; others have maintained that it gradually cools global temperatures. Scientists do agree that a sustained climate change in either direction could significantly affect the environment. It will affect the ozone layer of earth. Ozone is a gas that's found in both the Earth's upper and lower atmospheres. The protective ozone in the upper atmosphere is very different from the harmful ozone in the lower atmosphere. Ozone that exists naturally 10 to 30 miles (16 to 48 kilometers) above the Earth protects us all from Sun's radiation UV rays.
But ground-level ozone is different. It's found close to Earth's surface and is a serious pollutant. It's produced when sunlight combines and reacts with chemicals produced by cars, power plants, and factories. That's why ground-level ozone, a main component of smog, tends to be higher in sunnier climates or during hot, still weather.
One contentious air pollution issue continued to be the effect of smoking in public places, especially as it concerns the rights and health of nonsmokers. Many states have enacted legislation designed to protect nonsmokers in public places, and the battle between smokers and nonsmokers made its way into the courts. An increasing number of restaurants, airlines, and other public facilities dealt with the problem by banning smoking completely.
Asthma, skin diseases, suffocation are effects and people have to live in areas with levels of particle pollution that are unhealthy year-round.
In addition to ozone and particle pollution, other pollutants include gases such as carbon monoxide, sulfur dioxide, and nitrogen dioxide. High levels of these gases can also affect lung function.
