Is it just the environment and nature?

Are Americans well educated in everything except for nature and our environment? Do we know everything we should know about nature and our environment? I honestly dont think we know nearly as much as we should. I feel like as the more time goes by the less educated Americans are as a whole. How can we not be educated on nature when we co exist with it? When we basically are living it? I think its more than that. Americans just are not educated in many things we should be these days. There are just so many things in our every day life that we really dont know much of anything about and we really should. Another example of something Americans dont know enough about is slavery. Most people would say that slavery no longer exists and if it does it doesnt exist in our country. Well I have news for those people....IT DOES. There is still slavery today and in many cases it is a lot worse then it used to be. Many of the clothes and even the food we buy is made by or has been touched by slaves. So we are basically supporting the slave holders to keep maintaining their slaves and keep treating them they way they are and have been, with out paying them or anything. But those are just two examples of things Americans really just dont know too much about. Are we becoming dumber as the years go on? Are we becoming less aware of our surroundings and our actions? What will our great grand children be like? Its a scary thought...
