8. A Lack of Forests

11. Food in the Rainforests At least 80% of the developed world's diet originated in the tropical rainforest. Its bountiful gifts to the world include fruits like avocados, coconuts, figs, oranges, lemons, grapefruit, bananas, guavas, pineapples, mangos and tomatoes; vegetables including corn, potatoes, rice, winter squash and yams; spices like black pepper, cayenne, chocolate, cinnamon, cloves, ginger, sugar cane, tumeric, coffee and vanilla and nuts including Brazil nuts and cashews.

12. Medicine in the Rainforest As the rainforest species disappear, so do many possible cures for life-threatening diseases. Currently, 121 prescription drugs sold worldwide come from plant-derived sources. While 25% of Western pharmaceuticals are derived from rainforest ingredients, less that 1% of these tropical trees and plants have been tested by scientists.

48. Climate Change is Real As preparations for filming of The Day After Tomorrow accelerated through 2002, unusual weather patterns added a sense of urgency to the project. "With the floods in Europe and the breaking of that ice shelf in Antarctica, I realized we had to hurry up or otherwise we're making a documentary," film-maker Roland Emmerich said.

49. Is rapid climate change possible? “Yes. At the end of the last glacial period (10,000 years ago), the Younger Dryas event was a very sharp transition around the North Atlantic from warm conditions at the end of the last glacial period back to cold conditions which lasted about 1000 years before switching back to warm conditions. Scientists think that this was caused by the last major ice sheet in North America collapsing and putting a lot of fresh water into the North Atlantic. This may have caused the North Atlantic "overturning" to slow down, reducing the amount of heat transported toward the pole.”

50. Is rapid climate change possible? “Temperature and salinity differences in the world's oceans work together to create what is known as thermohaline circulation. This circulation pattern, illustrated in the figure, acts as a "conveyor belt," slowly overturning the oceans. The strength of the thermohaline circulation is strongly determined by the sinking of the waters associated with the Gulf Stream. This releases vast amounts of heat to the atmosphere, keeping Europe warm.”

52. Is the movie real?! “While aspects of the movie have a distant basis in fact and real theories of climate change, the film greatly compresses and exaggerates events. Scenarios that take place over a few days or weeks in the movie would actually require centuries to occur. Nevertheless, climate change is real, and is having an effect on Earth’s ice and oceans. Not tomorrow, or the day after, but today.” www.thedayaftertomorrow.com

53. Water, Water, Everywhere?! Water scarcity occurs when the amount of water withdrawn from lakes, rivers or groundwater is so great that water supplies are no longer adequate to satisfy all human or ecosystem requirements, bringing about increased competition among potential demands. Scarcity is likely to occur sooner in regions where the per capita availability of water is low to start with, and with high population growth. It becomes more serious if demand per capita is growing owing to changes in consumption patterns.
