Is it possible for our planet to "crash" due to being a closed biological system?
After watching a wonderful video by Mike deGruy, I was very impressed by the illustrations he used regarding closed biological systems.
Please take the time to watch the TED event talk below, and chime in with your insight and/or opinion, on whether our Earth will eventually end up like the other three examples given in the video.
Some feel this is a very big problem, and offer many different solutions.
What is your take on this issue? Is it an issue? Or is the Earth able to continue producing indefinitely?
