It's not too late, or is it?

Prevention is definitely the way to go, we've already lost a lot and we must start looking into preventing further losses. Invasive species need to be severely limited, once they are introduced we can't easily remove them... so our only good chance against them is to prevent them. We need to spend more money on our natural parks and other nature preserving agencies. If we don't, then many of our prized species will be lost forever very soon. We must also greatly reduce our deforestation, we can't afford to lose all of our tropical rain forests, which is most certainly where we are headed. Alternatives must be determined and put into action. I think with proper funding we could preserve a lot of the species and forests that we have, but it just isn't happening. Action must be taken soon or else we will lose countless species.
