In order to help the environment, I would turn off the lights when they were not in use. I could also try not to drop litter in the streets, in fact I would try to clean them. I would help the campaign to stop using spray deodorant, because they seriously damage the ozone layer.

Another very important thing is stop using plastic bags, because people use them in excess, and theese bags take a lot of years to degrade.

Probably the best way to help the environment, is start using renewable energy, such as wind or solar energy. They are not as pollutant as the fossil fuel, because they need a combustion to work, and the atmosphere retains those gases. The smog could be reduced using an electric source instead of fuel, or start riding bikes instead of driving cars.

A very serious event was the oil spill in the coasts of the United States of America, wich killed many animal species, that could be extinct.

I would try to inspect the dams companies, as well as the industries producing pulp, because they are the greatest water pollutants. And the ones that work with C.F.C., because they potentially pollute the air.
