Discuss the largest threats to biodiversity

Habitat change is one of the most prominent threats to biodiversity, driven by the conversion of natural land to agricultural areas. It leads to large declines in species numbers and species diversity within habitats. As the human population increases, so does the amount of agricultural land thus affecting biodiversity. Another threat is over-exploitation, seen by the example of marine biodiversity. Fish stocks have experienced a huge decline due to over-fishing and inefficient fishing methods such a trawlers that degrade the ocean floor. In addition to this hunting of animals has led to a sharp rise in species extinction rates such as the Black Rhino which is now critically endangered. A final factor that poses a threat to biodiversity are invasive species which can infiltrate habitats and threaten wildlife. The loss or addition of one species can affect the whole ecosystem. All these factors threaten biodiversity inn different ways and are becoming more prominent in today's world.
