There will be a great effect on the food chain which may lead to extinction of certain animals of that habitat . the loss of the habitat may make those animals to render into cities and they may get killed

The existence of biodiversity in nature teaches us that every plant and animal whether useful or not has right to exist on earth. Every organism is a part of our ecosystem.Loss of any organism endemic or otherwise effects the food chain and food web of that ecosystem, which has impact on the survival of other organisms. If the bio diversity slowly extinct then we see the extinction of some species tomorrow it could be our species. Hope this helps you
