Lions, tigers, and bears are on the decline all around the world.
Pollution, habitat destruction, and poaching are all whittling away the numbers of said species to the point that I would have to say within the next 50 years or so they will be extinct in the wild, only to be seen at circuses and petting zoos.
Let's face it, most of the resources we consume are going to run out at some point. It's just a matter of time.
Jared Diamond, author of Guns, Germs, and Steel, and Collapse, to paraphrase, described resource consumption as two horses racing; one is the move to sustainable development and alternative energy sources, and the other is stay the course, and it is just a matter of which horse finishes first.
What amazes me is the gong show between politics, business and industry, when it comes to talking about climate change, pollution, energy policy, etc.
I will admit to being oblivious to what is happening around me occasionally. However, we can't simply shrug our shoulders when we reach a critical tipping point and say how we're we supposed to know?
