noble sentiment.
But seriously over estimate the power of human being ..
Trees don'e produce oxygen because they know other creatures going to use it,
the produce it as a by-product after using up the carbon in CO2.
Insect and Bees don't give a dam whether we get fed,
they only want the nectars.
If there are no plackton, whales probably never exist...at all to start with...
They are all trying to survive !
Most creatures know exactly what they need, and take that only,
the rest would just falls into balance
the problem with most human being is , they don't know the difference between what they need and what they want..... and therefore can never be happy
