WHAT IF THE WORLD BECOME VEGAN?* Experts argue that a global change to a vegetarian diet would be dangerous. Many regions in the world depend on imported proteins and this has an environmental cost. In two thousand and seventeen**, a study made in the Polytechnic Institute of Virginia shown what would happen if the whole population of U.S.A. became vegan: - Lands designated for cattle raising would become farmlands. - The farm waste would augment because there would not be enough animals to consume it. Its incineration would produce two million tons of CO2 per year to the atmosphere. - Almost all the plant food would be manufactured by the chemical industry, and it would add twenty three million tons more of CO2 emissions per year. - In respect to the current situation, in this vegan country the total CO2 emissions would be reduced by twenty eight percent. However, the population would be affected by calcium, B12 vitamin, and some fat acid deficiency. - The quantity of food would raise twenty three percent, because farming produced more per hectare than cattle raising. - Many animals would have to be killed. In England, a reduction of seventeen percent in the last ten years was supposed: thirty five percent of land released for other uses; save twenty three percent of water; and twenty eight percent less of CO2 emissions. Nevertheless, the national goal is to achieve a thirty percent of meat consumption, off of the current one, by 2030. (*) If some expressions are too much informal, correct them. Please.
