Because it totally sounds like a great idea to let coal companies dump whatever they want into rivers and streams? Do you like bathing? Do you like eating fruits and vegetables? Do you like drinking water or putting ice in your drink? Then NO! This is crazy!
Disastrous chemical spills, badly polluted rivers (such as the Chicago River once was), accidental major oil leaks, poisoned water pipes for homes... We have learned this lesson time and again: water is vital and therefore must be kept free of contaminants by irresponsible human action. No exceptions. Protect our waters!
