If I own some land with a lake on it and you own some land where waterfowl like to nest because of that lake. And, if I drain that lake thereby driving all your waterfowl to nest elsewhere, that's too bad. You can't tell me that I have to leave the lake intact just because it will change the wildlife on your land. It's my lake. I own it. Therefore, I have complete control over it. Your rights don't extend over into my rights. If the situation were reversed, you would have the same right to keep or destroy your lake and I would simply have to deal with the consequences.
