Conservation & Eco System balance funda

I was just inspired by one of my members Rani. She started a Blog about saving Tigers. Good cause no doubt. But then why only tigers? Well, this thread, I would be discussing quite neutrally, not taking any side yet. Japan & a few other countries are actually not quite supporting the eco-balance funda. One more thing comes to mind ....... conservation of nature & Global Warming. So, hey !! While I would contribute my ideas later on this very thread, why don't you guys start putting down your ideas & opinions here?
