large cats have evolved to require a lot of destruction
health vs nutrition studies are probably still in progress, been half a century since more processed foods??
cell phone waves are new and the impact on the brain versus unhealthy nutrition and the impact on the body probably still has yet to be determined.
fortunately humans have machines that are capable of digging up the earth and defecting disease areas around still water.
nature would have a hard time with that one.
sustainable food and energy shouldn't have to cost much as long as you invest in them the right way.
