Due to the levels of extinction between species the loss of biodiversity has inevitably happened. The main causes of extinction are the oblivious as well as well aware human acts. Most of the time some ecosystems are destroyed in the name of progress to our human society. If the ecosystems are not destroyed they are decreased in their size. Also, the dumping of waste into seas and oceans cause potentcy to the ecosystems (Causes of loss 2010). This chain reaction of bombarding their ecosystems, destroying them in turn, then the inevitable extinction, leads to lower productivity. Lowere productivity means we as human beings suffer loss in crops and other resourses used from these ecosystems.
