Our environment hosts the entire human population. We haven't been treating our home with respect, as seen by our exponential dumping of wastes, creation of pollution, mild ignorance of ozone depletion, etc. The climate isn't something we can change at the last minute, it is something that needs constant nurturing and a watchful eye if we want to live on a planet with minimal dangers. By starting to focus more seriously on the environment, we are taking the first step to leading more cautious lives so future generations won't have to clean up after our mess and so we keep our symbiotic relationship between mankind and nature in good terms. Let humanity not be a parasite to this planet, but rather a catalyst to its growth and development, benefitting both us and them.
