Thats your mentality not mine.
well it's not actually.

let's say that we leave the populations alone. let the fish and the seals and the bears just eat whatever they wish whenever. If there're too many seals, then the fish will be eaten by them, depleting the fish population. The increase in seals means more polar bears to eat them.

(By the way, melting polar ice is not hindering bear populations. ice is a detriment to the bears, actually)

now, once there's not enough fish for the seals to eat, they starve to death. once the seals starve to death, the bears start to starve to death.

now what's more cruel? maintaining the populations at balanced levels? or letting a bunch of animals starve to death because they devoured all their own food source?

and by the way, the population I was talking about thinning is the Human population. because if you truly believe the world is overpopulated by humans, then thinning the HUMAN population is the only real solution. all others are just half solutions that accomplish nothing and cause more problems than they solve. I DO NOT support the thinning of the Human population.

once you've studied biology a little more and you've gotten a little older, you'll learn that the media offers a skewed picture on this situation. Why does the media skew things? because people believe them and pay money to read about it.
