The EPA was created to combat toxic waterways. We cannot trust companies to regulate themselves in regards to our environment no matter how much we wish we could. The world cannot continue if we have polluted all of it. We need to keep protections in place. This will also impact tourism. Streams are vital for outdoors activities. My mother is a fly-fishing guide. If you pollute streams and rivers, there will be no fish and there will be no fishing. It will severely impact mountain towns that rely on the tourists brought in by those type of offerings. They will shut down and cost people jobs.
