"Experts say over the next hundred years the "perfect storm" of population growth, resource depletion and climate change could converge with catastrophic results."

Anyone else watch Earth 2100 last on Tuesday night on ABC? It was a fairly grim look at how continued mismanagement of our planets' resources could very well be our own demise.

However, the program ended on a positive note: Small changes by many of us can make a huge difference. Installing a rainwater harvesting system, switching to LED lights, or insulating your attic are examples of the small things you can do to help preserve our planet for future generations.

Anyone else have thoughts on the broadcast?
