From an awesome site, giving Buddhist views on the plight of our planet.

We have destroyed our Mother Earth in the same way bacteria or a virus can destroy a human body. Mother Earth is also a body. Of course, there are bacteria that are beneficial to the human body, that protect the body and help generate enzymes that we need. Similarly, if the human species wakes up and knows how to live with responsibility, compassion, and loving kindness, the human species can be a living organism with the capacity to protect the body of Mother Earth. We have to see that we inter-are with our Mother Earth, that we live with her and die with her.
Its wonderful to realize that we are all in a family, we are all children of the Earth. We should take care of each other and we should take care of our environment, and this is possible with the practice of being together as a large family. A positive change in individual awareness will bring about a positive change in the collective awareness. Protecting the planet must be given the first priority. I hope you will take the time to sit down with each other, have tea with your friends and your family, and discuss these things. Invite Bodhisattva Earth Holder to sit and collaborate with you. Then make your decision and act to save our beautiful planet. Changing your way of living will bring you a lot of joy right away and, with your first mindful breath, healing will begin.
