  4. Infographics welcome, get schooled.

This is a science community. We use the Dawkins definition of meme.

Overpopulation is not a myth. 36% of the earth's mammalian biomass is Humans, only 5% is wild mammals. 71% of avian life is livestock. https://ourworldindata.org/wild-mammals-birds-biomass

Half of all "habitable land" (which includes everything except deserts, tundra, salt flats, beaches, or exposed rock) is used for agriculture. Half of all land, for agriculture. https://www.weforum.org/stories/2019/12/agriculture-habitable-land/

Industrial farming is not sustainable at the current rate and relies on either mined or petrochemical derived ammonia which supplies the nitrogen necessary for protein. Synthetic Ammonia alone feeds half the world population and requires an additional 2% of the world's power to produce.

The global ecoystem is in rapid decline.

I gave up finding appropriate sources halfway when I realized this post will just get removed eventually.

Humans today are like 300% more biomass than every mammal on earth 100,000 years ago.

This might come as a shock to you but there used to be 30 million people about six thousand years ago. Two thousand years ago we had 200 million. One thousand years ago we had 300 million. In 1750 we had 750 million people.

Now we have 8 billion people.

Did you perhaps mean to make a dinosaur joke but left out three zeroes?
