@JessicaLynn - Wow, that's a depressing perspective. I'm sure that even if there weren't rules in place, most companies would dispose of waste properly. But I do think we need regulations for those few companies that wouldn't do the right thing.
But, you will be glad to know that there are governmental agencies that inspect plants and factories. So hypothetically, if a company was violating these regulations, they would be caught sooner or later.
