Save the EarthSave the Earth

• “ My personal stand is this: As environmentalists, we are not trying to salvage the earth per se. We are merely buying time so that scientists and researchers can find scientists and researchers can find alternative forms of resources. … All they need is time. That’s All they need is time. That s where the environmentalists come in.”
