Solutions For Pollution

To combat pollution in the United States, the Clean Air Act Amendments of 1970 gave the Environmental Protection Agency (EPA) the authority to establish and enforce air pollution standards and to set emission standards for new factories and extremely hazardous industrial pollutants. The states were required to meet “ambient air quality standards” by regulating the emissions of various pollutants from existing stationary sources, such as power plants and incinerators, in part by the installation of smokestack scrubbers, electrostatic precipitators, and other filters. Auto manufacturers were mandated to install exhaust controls or develop less polluting engines. The Clean Air Act, as amended in 1977, authorized the EPA to impose stricter pollution standards and higher penalties for failure to comply with air quality standards.


In 1990 when the act was reauthorized it required most cities to meet existing smog reduction regulations by the year 2005. The 1990 amendments also expanded the scope and strength of the regulations for controlling industrial pollution. The result has been limited progress in reducing the quantities of sulfur dioxide, carbon monoxide, nitrogen oxide, ozone, particulate matter, and lead in the air. The EPA also regulated hazardous air pollutants, which in 1992 included mercury, beryllium, asbestos, vinylchloride, benzene, radioactive substances, and inorganic arsenic.
The most satisfactory long-term solutions to air pollution may well be the elimination of fossil fuels and the ultimate replacement of the internal-combustion engine. To these ends efforts have begun in the United States, Japan, and Europe to develop alternative energy sources (see energy, sources of), as well as different kinds of transportation engines, perhaps powered by electricity or steam. A system of pollution allowances based on trading emission rights has been established in the United States in an attempt to use the free market to reward pollution reductions, and the international sale of surplus emission rights is permitted under the Kyoto Protocol (see below). Other proposed solutions include raising electricity and gasoline rates to better reflect environmental costs and to discourage waste and inefficiency, and mechanical controls on coal-fired utility plants.


In 1992, 150 nations signed a treaty on global warming at the UN-sponsored summit on the environment in Rio de Janeiro. A UN Conference on Climate Change, held in Kyoto, Japan, in 1997, produced an international agreement to combat global warming by sharply reducing emissions of industrial gases. Although the United States abandoned the treaty in 2001, saying it was counter to U.S. interests, most other nations agreed that year on the details necessary to make the protocol a binding international treaty, and the necessary ratifications brought the treaty into force in 2005.

Solutions For Global Warming

We have the technology and ingenuity to reduce the threat of global warming today. Solutions are already available that will stimulate the American economy by creating jobs, saving consumers money, and protecting our national security. By investing in renewable energy and energy efficiency, and increasing the efficiency of the cars we drive, we can take essential steps toward reducing our dependence on oil and other fossil fuels that cause global warming.

Using energy more efficiently and moving to renewable energy (wind, solar, geothermal, and bioenergy) would significantly reduce our emissions of heat-trapping gases. The United States currently produces 70 percent of its electricity from fossil fuels such as coal, natural gas, and oil, but only two percent from renewable sources. Since the burning of fossil fuels releases large amounts of carbon dioxide—the leading cause of global warming—but renewable energy does not, increasing the share of our electricity generated from renewable resources is one of the most effective ways to reduce global warming emissions.

Cars and trucks are another significant source (25 percent) of U.S. carbon dioxide emissions. A serious effort to address global warming must therefore reduce emissions from cars and trucks. Many technologies already exist that can do this, while also creating new jobs in the U.S. automotive sector and other industries throughout the country. In addition, American consumers would save billions of dollars on gasoline, and we would reduce our dependence on foreign oil.

By putting energy efficiency, renewable energy, and vehicle technology solutions in place at the federal level, we can reduce our contribution to global warming while creating a stronger, healthier, and more secure nation

Solutions For Littering

1. Pick it up.
Litter can be picked up by volunteers or by paid employees. Hiring people to pick up litter can cost a business, park, or school a great deal of money. According to the Philadelphia Daily News (March 27, 2000) Penn State estimates that its landscapers spend 10 hours a week picking up discarded cigarettes at an estimated cost of $150,000. Some businesses also have their employees pick up litter from parking lots, entrances, and landscaped areas. "Adopt a Spot," "Adopt a Park" and other adoption programs involve volunteers in cleaning certain areas. Some schools encourage student groups to Adopt a Spot on campus that they clean at least twice a year. Cleanups are also organized by nonprofit groups, including the International Coastal Cleanup, an annual worldwide event organized by The Ocean Conservancy. Some states, including Virginia, have prisoners pick up litter along highways.

2. Education-educate people about the need to dispose of waste properly.
Studies show that litter can be decreased by 50 percent or more through educational campaigns. Signs, messages printed on packaging, personal messages, and presentations about the harmful impacts of litter will decrease some littering behavior. However, like any public education campaign, the educational message must be continual. A one-time educational effort will not result in long-term changes in behavior. We as a society must become intolerant of littering behavior.

3. Have a "no smoking" policy or allow smoking only in designated areas.
More and more public beaches, parks, open-air shopping malls, and college campus are trying to concentrate cigarette butt litter by requiring smokers to use only designated areas. These areas should have ash receptacles, lighting, seating, and be convenient. Often the use of these designated smoking areas are promoted for public health reasons (secondhand smoke) and fire prevention, as well as a litter-control mechanism. This approach is sometimes attacked because it restricts smokers' rights (after all, smoking is a legal activity), and it is trying to address one behavior (littering) by restricting another behavior (smoking).

4. Provide ash receptacles and trashcans at all entry/exit points of buildings, at bus stops, and other areas where people frequently need to discard their trash and cigarettes.
According to Keep America Beautiful, which is conducting a scientific study on cigarette littering behavior, these "Transition Points" are the places smokers need to discard their cigarettes before entering buildings or getting on a bus.

5. Distribute pocket ashtrays and trash bags for cars.
Many types of pocket ashtrays are on the market. Some are made of foil and are disposable, while others are made of plastics or metals, and can be used for years. These can be purchased in bulk and distributed by community groups or businesses as part of a litter-prevention campaign. Trash bags for cars are also frequently distributed by community groups that are trying to reduce litter.

6. Enforce litter laws.

7. Engage the businesses that make or distribute items that are frequently littered.
Beverage manufacturers, fast food restaurants, tobacco manufacturers, convenience stores and other such businesses could do much more to educate their customers, contribute to anti-litter campaigns, support local cleanup events, and invest in public education on litter issues. They need to take an active and responsible role in educating people about litter prevention, and devote resources to the cleanup of litter.

8. Anti-Litter Taxes
In some states, consumers pay a small "anti-litter tax" every time they purchase a canned or bottled beverage. These funds support anti-litter efforts. A similar tax on cigarettes, fast food and convenience food purchases would go a long way towards funding campaigns aimed at eliminating littering. Some countries and states have "bottle bills" which discourages littering.
