Depletion of Natural Resources

I believe collectively, we as humans are slowly depleting the resources on Earth.  You can say that the Earth's natural resources can never be exhausted.  Whether that is true or not doesn't matter at this point.  What matters more is the quality of one of the most important resources, water.  Supply may be inexhaustible, but is that water clean?  It is becoming harder and harder to find clean spring water.  The pollution and toxicity leaching into our natural water supply is something that we need to really be concerned with.  The chemicals dumped into our municipal water supply is poisoning us. It is something that I don't think there is a solution to at the moment.
