3 Limits to Growth (published in 1972) -It is a book modeling the consequences of a sharply growing world population and finite resource supplies. -It suggests some difficult situations such as finite resources, industrialisation, population explosion, worsen environment and climate Change that human beings should face in the near future.

4 The book used a model to simulate the consequence of interactions between the Earth's and human systems. Five variables were examined in the original model, on the assumptions that exponential growth accurately described their patterns of increase, and that the ability of technology to increase the availability of resources grows only linearly. These variables are: world population, industrialisation, pollution, food production and resource depletion. The authors intended to explore the possibility of a sustainable feedback pattern that would be achieved by altering growth trends among the five variables.

5 重要名詞解釋 (Explanation of Important Terms) * 溫室效應 (The Greenhouse Effect) * 全球暖化 (Global Warming) * 全球氣候異常 (Global Climate Change)

6 It is the rise in temperature that the Earth experiences because certain gases such as water vapor, carbon dioxide in the atmosphere trap energy from the sun. Without these gases, heat would escape back into space and Earth’s average temperature would be about 60ºF colder. The Greenhouse Effect Source: “consulted in May 2008”.

8 *The greenhouse effect is important as without the greenhouse effect, the Earth would not be warm enough for humans to live. *However, if the greenhouse effect becomes stronger, it could make the Earth become too warm. This may cause problems for humans, plants, and animals. That is → Global warming *Global warming means an average increase in the Earth's temperature. A warmer Earth may lead to a rise in sea level, and a wide range of impacts on plants, wildlife, and humans. This will cause →climate change.

9 2. 全球暖化 (Global Warming): 全球變暖現象是因自 １８世紀工業革命以來，人類大量排放二氧化碳等氣體 所造成的。全球變暖問題是指大氣成分發生變化導致溫 室效應加劇，使地球氣候異常 (global climate change) 。 Earth has warmed by about 1ºF over the past 100 years. Although the Earth could be getting warmer on its own, many scientists think that things people do are helping to make the Earth become warmer and warmer. Source: html, “consulted in May 2008”. html

11 Case of Haiti in As food prices keeps rising (have gone up by 50%), serious riots and demonstrations happened in April At least five people were killed. 2. The UN peacekeepers helped to control the situation. *Government’s Reaction and Actions: 1. Condemned the violence, and said the demonstrations were manipulated by individuals linked to drug dealers and other smugglers. 2. Making $10 million to fight the rising cost of food. 3. Creating more jobs and credit programs. →Results: Government fell as Senators fired the Prime Minister.

12 Earthquake Hits Haiti Where: Port-au-Prince, Haiti ’ s Capital When: January 12, 2010 Who: could be more than 100,000 dead How: 7.0 earthquake happened at 16:43pm (last 35 seconds) What: Many countries (eg. Taiwan)responded to appeals for humanitarian aid, pledging funds and dispatching rescue and medical teams, engineers and support personnel. On 22 January, 2010 the United Nations (UN) noted that the emergency phase of the relief operation was drawing to a close, and on the following day the Haitian government officially called off the search for survivors.

13 *Red Cross runs out of medical supplies *UN confirm 19 workers dead with a further 100 believed dead *Around three million people estimated to have been affected by the quake *World Bank pledges $100million to help recovery and reconstruction *Charities launch emergency appeals to help stricken survivors *Presidential palace crumbles, hospital collapses and houses swept away *UK sends emergency team as Obama vows 'unwavering' support
