Nature always speaks to us. Our bodies tell us what we need (and what we don't need) I shudder to think what priceless resources we are allowing to slip away because of deforestation of the Amazon and other places like it. We do need to stop and listen before it's too late. :MJ
It is a cycle of nature that has been repeated countless times throughout the history of the planet. A particular species achieves dominance. They thrive and their numbers increase exponentially. In the process, they consume more and more food (or other resources). Eventually their number reaches a point where their habitat can no longer sustain them (a.k.a. "population overshoot"), and then their number decreases exponentially, either to the point where they are no longer dominant or they are extinct. Then a new and different species gets their turn at being the dominant species. "The destruction of the natural world is not the result of global capitalism, industrialisation, “Western civilisation” or any flaw in human institutions. It is a consequence of the evolutionary success of an exceptionally rapacious primate. Throughout all of history and prehistory, human advance has coincided with ecological devastation." — John Gray, STRAW DOGS; found here:http://www.dieoff.org/ The primary reason for our own downfall will be the lack of the energy resources needed to sustain our numbers, or a final war over the energy resources that are left: http://www.jayhanson.org/problem.htm
I wonder why there are many people who make two out of it...nature (outside) AND human...as if 'they' were two different things....
