Another problem is farmland. We destroy large amounts of forest for new farmland. It takes a large amount more food to create meat than the meat contains. A simple solution to this problem can be found be eating our own dead. They slowly rot in caskets returning to the earth, while thousands of trees are cleared to create the amount of meat on that person.
Also war, we got a ton a ded layen around
There are also solutions for ALL problems~*~
Hahahaha very interesting perspective indeed. Though when looking at nature you can see a much less morbid example of this.
EVERYTHING dies and in nature simply decomposes into the ground either before or after it is food for something else. Either way it is food of which creates again and again.
Basically as I said everything humans do is unsustainable including food production and war. haha
