The fats are destroying the planet. Ez Proof.

The world is already having trouble feeding all the people it currently has. Fat people eat more than fit people. Assuming overweight people eat 2x fit people and obese people eat 3x here is the math.

13% of adults in the world are obese. 39% of adults in the world are overweight. One-in-five children and adolescents, globally, are overweight. - https://ourworldindata.org/obesity

7.9 billion people right now.

13% adults obese - 1.027 billion obese people ( Note- assuming same rate for children to get total percent of population same)

39% adults overweight - 3.081 billion

remaining people - 100% - ( 39% + 13%) = 48%. = 3.792 billion

Total amount of people as per food consumption increase because of fat people - 3.792 billion + ( 1.027 billion x 3) + ( 3.081 billion x 2) = 13.035 billion humans.

Fat people are causing 5.1 billion people worth of extra food consumption. They are what's causing the environment and the planet to collapse.

Note that the figures used here are actually a few years old. Already people have likely gotten way fatter.

Conclusions - Being fat is what is killing the planet. If you care about the future of humanity or saving the environment at all then you must stop being fat and convince those around you to stop being fat.

Godspeed gentlemen.
