As for man being the master of the Earth, let me remind you of the truth that all of biological and social human history is only a transient expression of the Earth and its biosphere.
What should be obvious is that we are in the midst of a global social, political, economic and environmental disintegration of mind-numbing depth and extent. In short, we are in a global environmental collapse that is a linear, more or less gradual decline until the threshold of total collapse is reached, at which point a mass extinction occurs.
There is a lot we can still do to arrest and mitigate the catastrophic events we must endure. A Green New Deal, based on sound social and environmentally just policies, is an essential first step. The choice is ours. Time is running out.
