**3.3 Loss in biodiversity**

Animal waste and droppings are not treated properly, as farmers often dispose of their waste in rivers, where they pollute the water and impend the biodiversity of the ecosystem. Waste products of poultry emit ammonia and nitrous oxide leading to nitrogen pollution of water and soil [24]. Uneven use of pesticides and fertilizers can also pollute soil, water, and air [25]. The continuous degradation of environment and loss in biodiversity is an alarming sign for global warming [25].
