Document Summary
However these wetlands have shrunk due to the lowering of th eland and the rising of the sea level, building levees and channels that now transport sediments into the gulf of mexico instead, and because of pollutants. Coast 2050 was a conservation effort that greatly improved sediment deposits in the delta and increased the number of species and biodiversity there. However, the project is expensive and makes us need to understand why biodiversity is important. Biological diversity: the wealth of species that lives on earth. It is commonly expressed in the number of species in a given area or the genetic diversity of an area. Biological evolution: presented by charles darwin in the 19th century, biological evolution is the change in inherited characteristics of a population from generation to generation. It usually results in a new species because it cannot interbreed with the original one.
