With the huge growth of the human population, human demand for food is also growing exponentially. Growing demand for food puts pressure on animal husbandry. Farmers need to provide more water and feed even growth hormones to amimals to let them grow fast and satisfy the meat demand. Moreover, animal husbandry causes more carbon emissions than any other type of industry. It is bad for our sustainable development and reduces the situation of climate change.
I envision a world where people have less desire for meat and try to eat more vegetables. So less demand for meat will cause less supply of beef. The carbon emission and water usage of growing animals will be greatly reduced. So we can better achieve the goal of the pair's agreement to reduce carbon emissions by about 50%. And make our world keep in sustainable development.
