It's coming home to roost over the next 50 years or so. It's not just climate change it's sheer space places to grow food for this enormous horde. Either we limit our population growth or the natural world will do it for us and the natural world is doing it for us right now.
The only thing I can say about having this type of success is that you can get yourself in trouble because basically the world is set open for you. People will say yes to anything you ask so it's basically down to you and what you want or need.
