<h3>Meat consumption and environment</h3>
Explanation:
Increase in population rises protein demand. Many people meet their dietary protein requirements mainly from animal sources by consumption of meat and meat products like meat, eggs, and processed meat products.
Increased meat consumption leads to increase in global warming. Increased meat consumption raises the demand for meat and animal farming like cattle, poultry and fish farming.
Farm animals release methane through their waste into the environment. Methane is one of the most potential greenhouse gases that cause global warming.
Animal farming practices requires a lot of water and hence depletes natural water sources. Moreover, the effluent drainage from farmlands pollutes the land as well as natural ground water sources with methane and other pollutants including pathogens and renders the natural sources unusable.
Further, farm animals like cows and goats grazes farmlands and destroys the green cover which helps in carbon sequestration.
