To commemorate the 50^th anniversary of Earth Day — a celebration that piqued my interest and deep participation for many years — I would like to honour three of my Earth Day heroes. These are individuals who have spent their lives in outstanding service to the Earth.

Could Nature be warning us through the COVID-19 global pandemic and the ever-escalating global warming emergency to "repent" our over-consuming, over-polluting, and unsustainable lifestyles and livelihoods before we experience a Great Collapse?

Lost in the Covid-19 pandemic news coverage is the current rapidly deteriorating state of the climate, which is more of an emergency than ever. This global threat to our survival is more real than ever. It will not go away by itself, we cannot make it go away, and our leaders, particularly the US Republican Trump government, are denying the threat. They are pouring more gasoline on the global warming fire.
