WOW... after reading all of your posts... I am fully amazed as to how COLORLESS is pretty bold and open to these sorts of things...
The problem, in my opinion, isn't on humans, period. But the notorious actions done by humans for a reason... let's take an example of the eco-field turned farmland... for a business venture at the expense of nature... new buildings for sales & commerce at the expense of nature...
well I could refer to more examples but my point is... it's what humans crave for that destroys the planet... and in my opinion... falls under one word: commerce. I agree on the fact though that humans save nature... but reality, not everyone is like that and there are more "commercialists" out there because of the introduction of well... money... that brought about greed and made rich men take advantage of wildlife for their own benefit, sacrificing it for a business venture... this is why i hate business & big-headed-world-known-businessmen... :/
