It's not a case of something like spaying magically solving all the problems anywhere. I cringe anytime I hear someone, a politician or somebody from the company I once worked for, say we'll make sure this can never happen again. That's ridiculous. That's impossible. Of course it can happen again. You're dealing with people. In my opinion, the goal should be to stop one school shooting, not every possible school shooting in the future forever. You should stop one major fire or pollution event. You cannot solve world hunger everywhere at once, but you can help out one family that needs the help, however you decide to do that. If you spay one dog or cat, that dog or cat will not contribute to the overbreeding of those animals. You will have contributed to the solution.
Bob, I'm not talking about you, I'm just ranting. Don't take it personal;. I see letters to the editor and hear people al the time on TV say things like "Doing this will not totally absolutely solve the problem so I'm not going to do anything." Yes, cows are going to fart and belch and be a major contributor to greenhouse gasses. So what. By reducing emissions somewhere else you are not making the problem even worse. We as a country cannot solve the emissions problem because other countries are contributing too. But if we are an exceptional nation, shouldn't we lead by example instead of saying "Do as I say, not as I do".
End of rant. I'm going to go see if the ground is dry enough to get some potatoes in the ground.
