Our 5 billion year old Earth has survived dramatic and phenomenal compositions or changes in atmospheric variations, geological forms, instable climates and diversification of species throughout history.
But no single, mass bio-species on Earth except the Homo sapiens (humans) has ever impacted negatively the course of nature on Earth.
It is not about saving Planet Earth. We need to change to save humans and all other species living on beautiful planet – Earth. The space is the Earth!
