Pollution is caused by human beings, some people are interested in not polluting and help the planet to stop this problem that affects us so much, but it is a part of the population that wants to collaborate with not affecting the planet. If more people were interested about pollution, we would have better air to breath, and if we had better air to breath, we would be a bit of healthy people. Unfortunately, in the past the people weren’t environmentally friendly, if they had been environmentally friendly, we would have been better humans for the planet and all the pollution never exist. Also, if they had taken care about the planet, any kind of animals wouldn’t have been in extinction. We as human beings have a duty to take care of the planet, look for options to educate the population to do it, look for ways to avoid contamination or littering, no smoke, or cars, in general and in the future it’ll be hardly any pollution but minimum.
