1. Mankind's violent nature
2. Over dependence: we have become over dependent on our machinery and cannot seem to function without it: (computers, television, automobiles.)
3. Related to the above is sloth: As machinery picks up the slack humans tend to become lazy.
4. Death of written arts: As television and the internet and gaming increase in popularity, pieces of written work fall into the background of culture.
5. Lose of local work: As the ability of satellite and telephone conferencing becomes more available it is possible to send more jobs abroad.
6. Health problems: as the automobile has slowly progressed so has its fuel. The formula for gasoline has changed several times, one of the most harmful was a gasoline mixture with beryllium in it with has been proven to cause cancer.
7. Cloning: While making a perfect Identical clone is currently impossible there is a problem with the basic genetic markers in most animal DNA that causes a major problem.
8. Pollution: It causes harm to the atmosphere and oceans.
