A saying goes thus: "As you lay your bed, so you will lie on it"
One thing we humans must realise it that every of our action still comes back to haunt us. We cannot eat our cake and have, cos life is all about give and take.
If we fail to take care of mother nature, there's no doubt that we won't feel her wrath. Therefore, Its high time we started paying attention to preserving our environment and doing things in a manner that posses no threat to it.
Certainly some of this agents of pollution are easily controlled but our selfish human nature wouldn't just allow us do the right thing and even the quota of the industry can be tackled by the appropriate means. For instance by adopting a kind of green technology called Cleaner Production.
We all need to embrace love for our sorroundings. Let's take care of it, cause indirectly we are taking care of ourselves.
By the way @pangoli, you did a great Job compiling this, well done sir.
