CONDITIONS THAT COULD MAKE LIFE POSSIBLE ON PLANETS AND MOONS OUTSIDE THE HABITABLE ZONE. WRITING AUDIOSCRIPT WRITING DIAGNOSTIC PRE-TEST Question 1, Page 321 [ mp3 147-148] (Professor) Well, despite what many people may think, there are strong reasons to support the banning of deforestation. OK, first of all, rainforest land is not sustainable as farming land. The reason for this is that the land is only good for three to four crops before the soil becomes useless for growing food. Additionally, there is just too much rain in a rainforest to adequately support healthy food crops. A rainforest has a minimum annual rainfall of 80 inches. The rain carries away the essential nutrients from the soil, especially after the protective canopy—or cover—of the trees is removed. If deforestation continues, farmers will need to continually move or cut down more trees to clear more and more fresh land to keep making money from their crops.

Many of those indigenous people have never been outside their rainforest and have had no contact with other people. Bringing new people in would not only destroy their way of life, but would also make the rainforest unsustainable. That is, the local tribes are able to farm, hunt, eat, and find fuel without disrupting the rainforest environment. Additionally, bringing new people to the area exposes the local people to diseases and infections they’re not normally exposed to, potentially leading to deaths among the population. Lastly, deforestation is devastating to the environment. There are direct links to the climate change it causes and to the loss of biodiversity. Deforestation is destroying the habitat for hundreds of species—plants, animals, and insects. Plants that are used for medicinal purposes are lost; for example, more than 25 percent of the ingredients needed for cancer drugs are found in the rainforest. The continued destruction may prevent future cures and medicines from ever being discovered. And, in general, the rainforests are believed to lessen global warming by decreasing carbon dioxide. They remove billions of tons of carbon dioxide from the air. Download 0.63 Mb. Do'stlaringiz bilan baham: |
