We humans, endowed with a large brain, dominate the planet. Unfortunately, that dominance has threatened the welfare of all natural ecosystems and their component species.
Since our brain power has also fueled an active imagination, we have concluded that we are the chosen species, created by a god and entrusted with the stewardship of Earth. Such beliefs have led to our divorce from nature and to its gradual destruction. Polluted air and water, ecologic disruption and climate change are some of the more significant consequences.
In reality, our planet's ecosystems would thrive in our absence. Despite what we imagine, we are the most expendable species on Earth. Accepting that truth and acknowledging the impact of our large brains are the keys to saving our planet.
