Some scientists believe that we are putting our own species in peril as a result of this accelerated extinction rate that is now occurring. Another study found that more than 50% of the earth’s land surface is now lacking sufficient biodiversity.
So what is driving the lack of biodiversity and the accelerated extinction? Humans are building on land that used to be host to a number of diverse species of plants and animals. Agriculture and roads are further diminishing biodiversity. These developments also weaken existing ecosystems by making them less resistant to change.
A lack of biodiversity can lead to problems in agriculture. Many crops that we depend on for food require pollination by insects such as bees and butterflies. If these animals are wiped out our food systems can collapse. This could devastate entire populations. Other concerns from a declining biodiversity include water quality, waste decomposition and carbon storage.
