When temperatures rise, our planet activates its own temperature control system.
It was narrated that the cloud cover from volcanic ash blocks the sun's rays reflecting heat away. This along with the fall out damages crops and other food sources but it does make the Earth cooler.
Thinking that since one of our problems is global warming caused by climate change, we may be moments away from when the Earth activates its automatic temperature control.
Given what the narrator said and with the high heat we now have globally, it will need a lot of cooling. To achieve this, Mother Earth will need to blow a lot of volcanoes.
This could be disastrous for us but it is a choice between the survival of the planet and most of the "defenseless" species and the survival of man.
The planet only does what is necessary to take care of itself and those living in it with those dying considered as collateral damages.
A means to an end. Sacrificing a few for the survival of the many.
We better change to help manage global warming before the planet itself takes action.
