Here is another taste of unscientific science. They dug up a skeleton in Washington that they immediately decided was Indian. They called it the Yakima man and dubbed it the first man in the Americas or something to the affect. Of course groups came out of the woodwork to claim it to further their cause. It turned out that it wasn't Indian but Caucasian. I think I read somewhere that they thought it was from Scandinavian decent. So maybe it was Lief Erickson's great great granddaddy or something.
Another interesting thing in their scientific quest was the test they did on a piece of wood that was under water after Mt St Helens blew up. They tried to carbon date it to check accuracy. It tested 5,000 years old although it was only 5 years old at the time.
Did you know cows produce methane gas and it needs to be controlled? There are fewer cows in 2015 than there were in 1940 but it's always the cows. We can't burn off our fields and they want to ban wood stoves but the Forest Service can burn down the forests.
Nature isn't static and stagnant. It's constantly changing. "Science" used falsely and with ulterior motives is causing great harm in this country. We have people who know nothing about growing anything mismanaging our forests and others trying to control everyone in agriculture. All this "scientific" data is padding the pockets of a few and it could really impact our ability to raise food and even exist. It's frustrating just watching it happening.
I believe that what is happening is just part of a natural sequence of events in nature. That's not to say people can't pickup their own garbage. It's also not to say that they couldn't quit having to have several homes and building new ones on developed agricultural ground. Maybe they need to quit farting and making so much methane gas. Heck there is a lot more humans than cows.
