The cause of most problems for any biological creature on earth is external. All animals compete fiercely for survival among the elements, among other creatures, among each other. Survival is the biggest problem for all animals.

Except humans. More humans die each year due to other humans, or due to things other humans have created (for example humans ignoring mask mandates).

Point is, we are the only specie who has become its own worst enemy.

Idk, what am I saying? I think we can improve eachother's lives quite a bit if we just kick out the assholes from power.
