Ottawa, Ontario, Canada, International Development Research Centre, 1990. 40 p. (Searching Series No. 1)There are many global problems. North and South are both worried about thinning of the ozone layer and global warming. This report begins with problems created by the North and the South. The next part shows how scientists in 3rd World countries can help solve these problems. The developing countries are seen as a laboratory where solutions to global problems are being found. Greenhouse gases are heating the earth's climate. This global warming will be bad for millions of people. The carbon dioxide build-up could double between now and the 2nd half of the 21st century. The earth's average surface temperature will rise by 2 degrees centigrade by the year 2030. This could raise sea levels. Scientists from different climates will have to get together on researching this problem. More than 1/2 of the genes of plants used by the West to improve agricultural species of develop medicines are in developing countries. Gene banks should be established. It is too late to stop global warming. Methane gets into the air from many sources. Nitrous oxide is another main greenhouse gas, as is carbon dioxide. The chlorofluorocarbon (CFC) gases also contribute to the greenhouse effect. Ozone is destroyed when chlorine from CFCs and bromine from halons are in the upper atmosphere. Acquired immunodeficiency syndrome is a new global health threat; as are travelling influenzas. The population will grow to about 6.2 billion by the year 2000; 9 out of 10 new births will take place in the 3rd World. The total debt of developing countries right now is more than US $1.3 trillion. This has doubled since 1980. Illegal production of narcotics is significant to various economies. There are many military threats to security. There are many scientists in the South and much health and biological research is undertaken there. In 1997, Brazil will manufacture alcohol-powered vehicles. Canada maintains many ties with developing countries. The North and South must cooperate on scientific research, including the international research centers that have been established in 3rd World countries.
