If you really want to do something about climate change, rather than just make some money from a popular story, then you should really look at the economy, the true root source of the great energy Ponzi.

That plays a much bigger part in climate change than most people realise, and it will never be fixed until it is realised.

As for overpopulation; people breed like crazy in response to threat. Remove the threat locally and and the population starts going back down.

Why would removing the threat globally not have the same effect?

The threat is scarcity, imposed directly or indirectly by those with no immediate danger of experiencing scarcity, upon others already experiencing scarcity, driven solely by profit.

Turning our backs on, or worse, somehow justifying the Massacres of people, like in Rhwanda, or of the Rhohingyas, or the natives of the Rainforests in Brazil, or in our prisons, or in the streets of our cities, or in any number of other places, is the real thing that will lead to further atrocity which will eventually envelope all of us, very soon.

Profit is our biggest enemy, that even blinds us to its harmful effects.

Getting rid of it requires that we remove all possibilities of it, in the only way that we can, by utilising the true source of all energy, the sun.

Fix that, and everything is fixed.

Planet Earth is only full if it is seen as a closed box, where the sun never shines.
