__Human Impact on the Environment __ More than 70,000 plant species contribute to the production of medicine in the world. 50% of modern medicine and 90% of traditional medicines come from plants and animals in our environment. Cancer, HIV/AIDS, Alzheimers Disease, and Diabetes could be defended against with medicines made from coral reefs. Destruction of nature by humans is causing human disease to increase. Examples of this destruction would be deforestation, reef destruction, agricultural development, disturbing water flows, urbanization, and changes in the climate. Disease carrying organisms,called vectors, are increasing in numbers are a result of the impact in the environment by humans.

Question: What impact is global warming causing to our ecosystem?

Answer: Because of the increased temperature caused by global warming, disease carrying insects that are native to warmer climates will move, causing an increase in the spread of disease. In wetter locations, global warming could make them dry and hot, causing droughts. This will affect the economic situation of the country. Polar ice caps will melt with global warming and cause changes in the water level and temperature. Only the most adaptive species in the ocean will survive.
