Since the last World, the world's psychological health protection have increased, However, the health of the human spirit in Spain. World Health Organization WHO estimates there are about 500 million people of the Earth was troubled psychological disorders. By the year 2020, depression will be scheduled in cardiovascular disease as the second largest cause death or loss of a strong production capacity disease. The life cycle of human growth and aggravate the problem, people will have to face more time to loneliness and no according to the old. (Recommended ah, the good films) the United States over the age of 65 groups disproportionately high suicide expected.
Corresponding to yes, the University of California scientist Gregory Stock of the development of Chinese medicine that will allow people to live to more than 200 years old. If this expected to achieve, we will be faced with unpredictable social and psychological challenges. 200 years of accumulated feelings to the brain may have contained a new psychological and brain diseases, may be the end of Baidoa bred to flourish. At present older crowd depression and suicide problem will continue. And perhaps the solution, "Prozac"(antidepressants) taking the formula, the final effect is not yet known. We do not have long-term impact on the effective use of data.

When human life single-handedly led to the extinction, but also through genetic engineering to create a new species. Modified crops than with ordinary crops, more full, more delicious, more nutritious. GM after the microbial help mankind solve a lot of medical problems. Gene therapy for the amendment of human DNA defects possible.
Biotechnology However there may also be hazards. Although there is no evidence that transgenic food insecurity, but there are signs that the new improved species gene may "leak"and "flow"to other species. Moreover, the modified crops may also increase resistance to pests. Jeremy Rifkin and other scholars feel has long been suspected of concern "super rice"and the resulting "super pests"will further worsen the already fragile ecosystems. After the change of the microbial gene may be difficult to remove.
However, the most worrying thing is that biotechnology might be abused. If a terrorist organization or rogue states that anthrax is not enough to achieve their goal, they may try other methods, such as air-borne by the manufacturers of the Ebola virus - Obviously, this will become a major human disaster.

Think about, the hunting of wild animals, burning forests will occupy some media tiny space, but behind that there is a great crisis - the loss of biological diversity, the situation is becoming more and more serious. After Qianbaimonian evolution, nature has given birth to countless species, but, there is no overwhelming advantage species exist.
Recently at the Royal Island National Park, the study gives an example of the cold winter makes more elk hunting wolves, elk leads to the reduction of the number of tree seedlings Fengzhang Xiangzhi, and a decrease in the saplings Carbon dioxide concentration was reduced insulation performance, everything is linked. In order to guarantee human needs, we are creating more and more houses and agricultural land, diverse ecological changes to the surface of a single species of crops, animals and plants transfer, and the artificial nature adds more unnatural chemicals .
Due to human activities, each year there are at least 30,000 species disappear from the earth, in other words, we are creating a personal history of the earth's largest-scale genocide. Yale University scholar Stephen Kellert ecology, human beings are destroying the Earth's ecological balance and details of large-scale disasters are likely to sudden disease spread, and insect pollination may also be gradually disappear, it will be the result of succession is a global crisis crops . In other words, we are moving towards a crisis we simply unexpected, as we discovered, too late.
