Biodiversity

1. Preserving local biodiversity have global effects because much of our resources come from different parts of the world. If India where to be hit by a flood(because of logging, areas can be hit my monsoons much more frequently and more severely) then the world economy would be effected.
2. Like all organisms, people need the rest of the world, all the plants and animals that help us to survive. Take them away, and we slowly die out with them, much like a domino effect. When one falls down, more fall down with it, and that rule still applies to humans, even if we thin of us as superior to the rest of the world.
3. Preserving biodiversity if important because many of the poorest people in the world depend on on biodiversity for food, fodder, or even medicine! Take biodiversity away, and we have a huge crisis on our hands with people in countries like India going hungry. Also, medicine is found in many type of plants, take away those and we could be preventing the human race from finding vital medicine for our future.
