It is cruel and unethical to kill animals for food when vegetarian options are available. Animals are sentient beings that have emotions and social connections. Scientific studies show that cattle, pigs, chickens, and all warm-blooded animals can experience stress, pain, and fear. In the United States about 35 million cows, 115 million pigs, and 9 billion birds are killed for food each year. These animals should not have to die to satisfy an unnecessary dietary preference.
In addition to the cruelness of killing animals, scientists have proofed that a vegetarian diet delivers complete nutrition and can provide health benefits. It can meet protein requirements as well as all the necessary vitamins, fats and minerals. It reduces the chances of developing kidney stones and gallstones, as animal protein cause the body to excrete calcium, oxalate and uric acid, which are the main components of kidney and gallstones. Also a vegetarian diet helps build healthy bones because vegetarians absorb more calcium than meat eaters.
Calcium in meat eaters' bodies is mostly lost because they are used to neutralize the acid in meat. Furthermore, a vegetarian diet lowers the risk of heart disease and blood pressure. In all, people pro vegetarianism claim that vegetarians live longer than meat eaters.
Besides the two points I have mentioned, being a vegetarian is also earth-friendly. Raising animals for food creates 18% of global greenhouse gases, more than the transportation sector. Greenhouse gases are created by animal farts and burps, manure decomposition, and deforestation to make room for grazing animals. A pound of pork produce as much greenhouse gas as a small car drives about 5 miles, but a pound of potatoes only equals 0.34 miles.
On the other hand, there are also people argue that being a vegetarian is a bad idea. First of all, they...
