Global concerns Overpopulation population growth would outstrip food supplies-starvation Possible solutions • “One Child policy”-China • 2050 India's population will have exceeded China Deforestation • Clearing of rainforests/forests • Central and South America, Africa, Asia (rainforests) Alaska and Canada (forests) • Endangered species Possible solutions • Save the forests • educate farmers • replant trees • restrict cattle grazing • reforestation Environmental pollution Acid rain • sulfur dioxide and nitrogen oxides-harmful to plants and animals Global warming • created greenhouse effect-warming of the earth creates melting of polar ice caps, rising sea levels, droughts Ozone layer • thinning, protects Earth from suns radiation Nuclear Waste • can contaminate for millions, of years-Chernobyl (86) (Ukraine) Possible solutions • Earth Summit-1992 and the 2002 Kyoto Protocol: nations devoted to achieving industrial growth without increasing world environmental problems • Burning of fossil fuels to wind and solar power The Green Revolution (1960’s) Increasing the Food Supply: • Due to the overpopulation problem in the world scientist needed to find a way to increase food production. • New fertilizers, pesticides, grains and livestock were developed. • In the 1960’s this new technology was introduced to poor, developing countries such as India and Indonesia. • The new technology was a success and was called the Green Revolution. Problems with the Green Revolution: • While the Green Revolution increased food it did not end poverty or world hunger. • Technology had limitations. • Populations grew faster then food production. • Poor farmers could not afford the new technology. Terrorism Terrorism is the use of unpredictable violence, especially against civilians, to gain revenge or achieve political goals Terrorism is usually used by groups of people who do not have their own military power in their country.

Desertification is caused mostly by human activity. o Overgrazing by livestock such as sheep and cattle eliminates the grasses that hold the soil together to prevent erosion. o Cutting down forests robs the land of another barrier to soil erosion. As grass and trees are eliminate, the soil loses it’s nutrients. The expansion of deserts is one cause of famine. • Possible Solution • • • • Reforestation-educating about soil reallocation Natural disasters Earths random processes • Tsunami • Earthquakes • Hurricanes Possible solutions • Preparation • relief North/South Dichotomy Gap between rich and poor Possible solutions • loans and economic aid • World bank source of financial and technical assistance to developing countries around the world • IMF: International Monetary Fund facilitate international trade promote high employment sustainable economic growth reduce poverty around the world Financial crisis 08/09 U.S. • triggers a worldwide recession due to multinational corporations • Interdependance • “overlending” and lack of government regulation possible solution • increase government regulation World Health problems AIDS West Nile Virus Possible solutions • New knowledge about viruses and DNA determine causes of diseases Status of Women Inferior status in many parts of the world Under represented in politics and business and on average earn less than men Possible solutions • international organizations attempt to prevent the inequalities • UN • Universal Declaration of Human Rights It states that all human beings are born free and equal in dignity and rights Everyone has the right to life, liberty, and security of person Many people around the world became involved in assuring that these rights were respected Many organizations, like Amnesty International, work to track human rights violations Nuclear Proliferation The spread of nuclear weapons and information about nuclear weapons Important advancements Antibiotics Scientists have developed antibiotics that treat diseases associated with bacteria Vaccines Vaccines have helped to eliminate some diseases such as smallpox and prevented the spread of many others.
