Solution

In order to check the animal agriculture and its impact on the environment, it is important to move to the VEGAN diet. Again taking VEGAN diet checks cancerous attacks, diabetes, heart diseases, obesity etc. The grains, pulses, cereals have been rich sources of fibre, healthy fat, carbohydrates, proteins and vitamins with packed antioxidants. Again due to VEGAN diet, grains get available plenty to human-beings and the risk of malnutrition in children and people gets decreases. The main purpose behind taking B12 supplement by the VEGANS is the VEGFOOD which do not provide the necessary B12 supplementation posseing the needed cyanocobalamin (cobalt) for the necessary functions within the body. The wholefood and plant based food materials have been deficient in vitamin B12. Whereas the herbivorous animals have a becteria in their digestive system which produces enough B12 and this B12 gets supplied to NONVEGANS through their flesh eating behaviour. B12 is necessary for the formation of red blood cells,to check anaemia and also for proper working of nervous system. Again VEGANS need source of B12 from vegetarian sources such as nori, spirulina, wheat grass etc. So the B12 derived form VEGAN source has been taking by the VEGANS as food supplement.
