The whole sphere faces population and excessively increases the challenge
It is reported according to report of January 12 of Britain " daily post ", a research report which Britain delivers reveals, within 60 following years, global population will present momentum that explosiveness increases, from 6,900 million 9,500 million rising violently to 2075 yearses at present. The whole sphere faces the insufficient challenge of resource, need close cooperation between various countries.

" the one earth, countless persons "'s report that Britain's mechanical engineering SCTE releases recently points out, the whole world is on the edge of overpopulation, because the crowded metropolis has already pressed the resources which is done the global importance. Population growth, especially the population growth of the new developing country is " decisive challenge in 21st century " ,The excessive growth of population is a threat greater than climatic change. Main author Tim and Fox in this report says: "By the end of this century, the whole world will face the challenge brought in greatest population explosion in the history of mankind straightly. "

The report claims, the whole world will increase 75 million people every year, it is equivalent to the population of Britain, within 60 following years, global population will rise violently to 9,500 million people of 2075 years from 6,900 million people at present.

It is newly-increased most populous at continent and city of Africa. Global urban population will be from 3,300 million 6,400 million increased to 2050 yearses in 2007. Now, about 1/3 of the people in the world live in the slum area in the city, as the city becomes more and more crowded, more people will live in the slum area. These people will endure the hungry torment which is short of water to the fullest extent, may initiate the conflict, cause the urban turbulence.

Research report this point out without violent change, the earth offer enough water, food, energy come, meet so many basic demand of people not being unable. Climatic change will probably bring larger pressure to the earth resource, will force 1 billion people to be never suitable for the place that the mankind inhabits to move. By 2030, mankind's demand for water may increase by 30%; By 2050, the mankind may double the demand of agriculture.

This report finishes with the help of more than 70 engineers in the whole world, has put forward a series of " development goal of the project " too In order to avoid the emergence of these calamitous incidents.

The report calls upon global engineers to take action, regard " millennium development goal " of the United Nations as the goal, solve energy, water resource, food and urbanization,etc. problem that the mankind faces. The solution that the engineers put forward includes reducing energies to waste, improve the food and store the way, collect water resource,etc. from the underground aquifer. If accomplish these, may let the earth support 9,500 million people.

It may need several thousand billion pounds to finish these goals, however, if the developed country can bear more fund, and what that shared correlation technique, these possible thing of the mankind, and the key is to help the undeveloped country to jump over " resources were consumed greatly " that the developed country had gone through Course of industrialization.

By 2050, European population is expected to reduce by 20%, however, in one world with ever closer connection, lead to mobilize whole body, global population increases sharply the influence brought and makes any countries and regions unable to sit on the sidelines. (Liu Xia)
