Explain why protecting surviving rainforests from deforestation is important to fighting cancer.
answer
Twenty-five percent of the active ingredients in cancer-fighting drugs are derived from rainforest organisms. And since only 1% of rainforest organisms have been tested for their anticancer properties this means there are many other potential drugs waiting to be discovered. If the rainforest organisms are destroyed before they can be tested, then many potential drugs might be lost before humans can discover them.
question
Compare the different conservation efforts being applied to protect rainforests.
answer
Ecotourism is being used to show people the rainforest in its native state and to educate people about how they can help protect it. Rainforest rehabilitation efforts are rebuilding forests in certain areas where they had previously been removed. Carbon credits arose from the idea that global carbon emissions should be capped and the appropriate number of credits would need to be acquired or purchased to offset a given amount of emissions.
