What could environmental groups do to response to air pollution? thanks

Pollution is hard to control. Many things that cause
pollution are of benefit to us: factories make our essential needs and provide us with
jobs, motor vehicles get us around and power stations produce the electricity we use.
Seeing that it is impossible to totally prevent pollution, steps should be taken by
environmental groups to identify and eliminate the more dangerous forms of pollution.
Environmental groups should encourage factories to use electricity in place of fossil
fuels, since burning of fossil fuels such as coal, oil and gas is another source of
pollutants in the air. Combustion releases harmful gases like sulphur dioxide, carbon
dioxide and nitrous oxide into the air. The constant release of these gases into the
atmosphere can create problems. As an example, excess carbon dioxide in the atmosphere
creates a temperature barrier known as the ‘Greenhouse Effects”, making the whole Earth
heat up. This then causes change in the climate and also disrupts rainfall. If this is
not prevented, the Earth’s whole eco-system might be altered or even destroyed. Apart
from these, they can put forward a proposal plan to the government to impose stricter
laws to restrict the release of harmful gases from vehicles and factories. They should
also take efforts to clean up air contaminants and plant more trees in the cities to
balance the carbon dioxide content in the air. Another environmental groups’ response to
air pollution would be to launch an important campaign. As you have probably heard, the
campaign is called “Green campaign” and aims to combat Greenhouse Effects. As a result
of all these actions, this will deter the public from getting involved in practices like
open-burning of rubbish.
