Well yeah, the Amazon rainforest is causing the climate crisis.
If you know anything about climate science, you know that the earth has limited resources. Large forests and other ecosystems, like the Amazon, are a massive debt on the earths yearly supply of resources.
Think of it this way: Put yourself on an island with 50 people. You are tasked to survive, and thrive on this island, and you are provided with a yearly supply of food, divided into 50 sets for each member of the community.
Now imagine, there are 47 normal weight people, and 3 obese people. The obese people will, naturally, override the groups needs with their own gluttony. Each fat person counts as two people, so rather than 3 obese people, you essentially have 6 normal weight people, or 53 total people. This does not compliment the 50 sets of food.
The viable solution? To kill the fat people. Killing the fat people leaves you at 47 people, with 50 sets of food, making you qualified for overstock; something essential in building a long term community.
Additionally, the fat people will provide excellent resources: The lard can be used to make moisturizing soaps, fire starters, etc.
To kill the fat people, is to thrive.
To destroy the Amazon rainforest, is to end climate change.
