People today have forgotten they're really just a part of nature. Yet, they destroy the nature on which our lives depend. They always think they can make something better. Especially scientists. They may be smart, but most don't understand the heart of nature. They only invent things that, in the end, make people unhappy. Yet they're so proud of their inventions. What's worse, most people are, too. They view them as if they were miracles. They worship them. They don't know it, but they're losing nature. They don't see that they're going to perish. The most important things for human beings are clean air and clean water.
