Why is being Healthy and Environment friendly so EXPENSIVE?

Everyone seems to think that when it comes to our environment there's nothing we can do. Global warming? It's fiction, our weather patterns are allows changing and it's normal. The people who do believe say now that it's too big of a problem to deal with. There's nothing we can do and even if there's anything that can be done, it's cost would cause damage to our economy. Eating Healthy? It would cost too much, to change the ingredients of the food to have less sugar and more herbal, natural ingredients. So the people who know that affects of eating the way most of us do and choose to eat healthy are subjected to high prices because only certain places sell these "new" foods. People, doesn't the word natural mean anything to you. It means it comes from NATURE. So why is it so expensive to be healthy? You would thing that adding more things to our food would be more expensive but we have made it so that its the complete opposite. The commons, which were given to us from nature are now being used against us and are in fact being destroyed. That's what Americans about, having bigger and better things than everyone else. This is something we NEED to learn how to get away from and try something new. Try the healthy way of living.
