Biodiversity threats are one of the major concerns of today’s intellectuals. These threats arise due to environmental problems that appear both due to natural processes as well as anthropogenic activities. Human activities that affect biodiversity are in fact critical environmental issues. These not only adversely affect humans but also other forms of life. Biodiversity is not an optional bonus in human affairs, but it is the foundation of human life and necessary for the existence and survival of humans and their sustainable development. So biodiversity conservation is not only a necessity to save the species but also helps in the conservation of habitats and such action is also likely to mitigate climate change. It is almost evident that habitat destruction and fragmentation, overexploitation, invasive species and climate change have the potential to create havoc in biodiversity loss. A major role in this regard is imparted by humans and their unsustainable and indiscriminate activities including overpopulation. This review article describes a correlation between anthropogenic activities and biodiversity threats i.e. the various types of anthropogenic activities that are responsible for biodiversity threats and loss.
