Essentially, Humans ruin everything...

So, everyone knows that the human population is increasing exponentially. Right now, the population is already at an unstable 6.6 billion, and is expected to increase by 3 billion in the next 30 years. So when will humans finally learn the lesson of their constant reproduction? Well looking back at how well humans learn from their mistakes, probably never. We are devastating the populations of the species we share this earth with. But humans continue in their poaching, hunting, and tearing down habitats. Humans are ignorant and most could care less about other species as long as they are still alive.
Humans are like a cancer to this world, spreading rapidly and destroying everything with no way to stop it. So how do we cure cancer? People have come up with some really creative and good ways to control the population, but these actions will never be initiated unless people are convinced slowing population growth will really benefit them. Although steps are being taken all over the world to try and stop our rapid population growth, other drastic measures would have to be taken to repair what we have already destroyed. And I could list all the ways I believe population could potentially be controlled, but that's not what this is about.
This is about the biodiversity of all living things we are destroying on this planet. I really detest anything that has to deal with harming innocent animals, so I feel really strongly about stopping useless hunting and poaching. I don't see how some people can be so cruel to animals, they are so cute and innocent! Even so, things need to be done to protect not just animals, but also the biodiversity of plants. If we had things my way, I would put the death penalty on ANY person who harms ANY wildlife. That would get rid of the population problem, and the loss of biodiversity problem. Ok, now I'm kinda scaring myself....
Well all people definitely needs to be educated on the effects they have on wildlife. This would help some of the issues we have on loss of biodiversity, but would definitely not fix the big problem we are facing. We need these animals for many reasons, and even if we didn't, they still have the intrinsic right to live! I believe this is a hopeless cause, because people can not be taught to care about animals. Forests can be replanted, but biodiversity can never be restored...
