Biodiversity protects ecosystem against infectious diseases. Increased human contact with wild life have caused high impact diseases such as SARS, Novel Corona virus, Nipah Virus, Ebola fever and many more. Anthropogenic activities such as hunting, farming, human encroachments, wild life trade, introduction of domestic species, bush meat hunting, road building, mining and increased human wildlife contact rates have lead to massive decline in biodiversity and increased risk of spilling over of dangerous viruses from animals to humans primarily due to host shifts. Human preference to high meat diet is also on rise in many countries. Wet markets have significant contribution in amplifying epizootic virus transmission and increased human exposure. Species in the primate and bat orders harbor a number of zoonotic viruses. Our destruction of nature, loss of habitat and biodiversity possibly tend to promote viral emergence. Invasion of undisturbed places leads to more and more exposure and create habitat where viral transmission is easier. Interference with a natural environment/habitat can, therefore, worsen the health risks. The erosion of biodiversity may lead to proliferation of species that are most likely to transmit new diseases to humans. Preserving habitat, biodiversity and natural environment is therefore one of the essential issues that cannot be put at the back any more.
