Everything has a limit, EVERYTHING! Once you exceed those limits.... London almost wiped itself out, LA almost wiped itself out. The planet has a balance that we are doing our best to upset. I believe the earth is going to do what the earth is going to do, but resources are finite. Once there gone, there gone. I remember saying "What a-hole is going to pay for water in a bottle, when they can turn on a tap?". The swill the water dept. calls water is barely drinkable. I gave my parents a filtration system for Christmas a couple of years ago. What an eye opener that was. The filters are supposed to be changed about every 3 months. The most they get out of a filter is a month! They are so brown, you can see contaminates right in the filter media. The filter & a water sample was sent out to a private lab, on my Dad's dime. The results were startling to say the least! Some of the heavy metals were up to 400% above maximum allowable. The city's recommendation was (no bullsh*t) to take the filter out! Have it in writing! Calling the newspapers, TV stations, EPA, etc.. did no good whatsoever. I've seen the results of other "non-existent" problems, I'll choose to err on the side of the scientist that say it does exist. I'm not saying I'll be trading the Imp in on a horse anytime soon. That's what Al Gore wanted us to do. They're trying to do away with the EPA. The way that they've sold out to industry, I'm not so sure it would be such a bad thing. But imagine if they did, & wiped all the clean air, water, & environment laws that've been passed in the last 100 years. That's what they want to do. We see how they screw up the enviorment WITH all these laws on the books, imagine if they were left to the honor system! I'm no tree hugger by any stretch of the imagination, just a little food for thought.
