This was an excellent post. I have actually thought a lot about this myself. A lot of my concerns are health based its actually somewhat difficult to replace complete proteins in a pure vegan diet. Also, having a lack of meat or fish in a vegetarian diet can make it hard to get enough Omega 3 and Vitamin D in their diets.

Environmentally, vegetarianism can cause significant ecological harm. Many farms and produce producers unless they are truly 100% organic usually use pesticides and insecticides that kill plenty of other animals like insects as well slowly damaging the water supply for people.
