I think this just says it all (from this article on M&G)

"The systematic destruction of the Earth's natural and nature-based resources has reached a point where the economic viability of economies is being challenged -- and where the bill we hand on to our children may prove impossible to pay,"
Just take a minute to think about that, "the economic viability of economies is being challenged."

This is not about polar bears or whales. This is about you and me. What will happen to you if our (or any other) economy is no longer viable? Can you and your children afford that? Can you afford to change right now?
