If people are crazy for collect, and wear diamonds as shiny jewelry, they seemed to be arrogant to nature as well as to other people. Because what they like diamond is they like to own rarefied and precious things. Their thought about nature like animals is just dogs, cats, and cows breed quickly, and animals such as lions, tigers, snakes, and bears are dangerous if they escape. They don’t know animals life way, how to raise them, how long animals can live. Because they always concentrate on rich themselves. They don’t know love nature, animals, human, environment. In Africa, Because of people who are crazy for diamond, diamond trader who usually live other country has come the town that easily can be founded diamond in Africa. They kill animals ,because animals like foxs, lions, tigers, and bears may attack people. Even they shot villagers , so they don’t have right side arm, legs. Because traders snatch more diamond from villagers. This is the worst case against naturalism. So I think nature gives us disaster. In detail, it gives viruses like HIV, SARS, and the pest which can spread easily. Because nature got anger to human.
