What If The World Went Vegetarian? - YouTube


If all the humans on the planet become vegetarian, what is the impact on the earth?


The proportion of vegetarians is very small from the whole population and only 4 to 5% in the US and Canada. Meanwhile, India, which often avoids carnivorous reasons for religious reasons, is 30% of the population is vegetarian.


There are now 20 billion chickens, 1.5 billion cattle, more than 1 billion sheep and nearly 1 billion pigs as livestock, because many people on the planet eat meat.


If all humans on the planet become vegetarian, these livestock will disappear. So what happens when livestock goes out?


A lot of land is necessary to raise livestock. Today, the vast land of 33 million square kilometers, equal to the size of the African continent, is used as a meadow for growing livestock ... ...


In addition, there are lands for growing grain which is feed for domestic animals.


As livestock disappears from the world, existing meadows are not suitable for growing crops, so there is the possibility of desertification if you leave it.


However, it is also possible for human beings to transform themselves into forests or grasslands by enriching soil.


When forests are created in the land used for livestock, the global environment will change. Livestock is considered to be one of the reasons for global warming, but since trees absorb carbon dioxide, as trees increase, carbon dioxide on the earth decreases and it is possible to suppress the progress of global warming .


Also, it is said that methane gas contained in burp and fart from ruminant animals such as cows is 25 times as greenhouse as carbon dioxide. In this regard, when livestock disappears from the world, the amount of methane gas generated also decreases.


Together with the increase in forests and the decrease in methane gas, it seems that greenhouse gas can be reduced by 15% if there are no livestock. This is bigger than eliminating planes, trains and cars from the planet, and among scientists there are many people advocating a method of "reducing carnivorism" as a strategy to stop global warming I will.


In addition, 70% of water consumption in the entire planet is used for agriculture. For example, the amount of water used for 1 kg of beef is 15,000 liters.


For pork it is 6000 liters.


For chicken meat it is 4000 liters.


When it comes to plants, the amount of water used decreases much, and the cereal used for cereal is 1600 liters.


For fruits it is 900 liters.


For leafy vegetables, we consume 300 liters of water per kg.


Replacing it with the proportion of water per kilocalory, the amount of water contained in 1 kg of meat is equivalent to 5 kg of fruit, 7 kg of vegetables, 20 kg of grain.


So what is the disadvantage of being born by people on the earth becoming vegetarians?


First of all, cosmetics such as leather or animal fat that was a by-product of livestock are not cheap as before.


Furthermore, more crops such as soybeans are needed, so we need the land to raise crops. Therefore, the land where livestock does not exist will not return to the natural state, but most will be used for farming.


Also, it is said that 1 billion people currently live by livestock are farmers, many are farmers and small farmers in developing countries. These people are forced to change, such as converting to agriculture by livestock depletion, concentrating on the shipment of milk and eggs.


Vegetarians are gradually increasing in each country, but on the other hand, in fact the opposite movement is actually occurring in the world. As wealthy countries such as India and China are populated, consumption of meat is increasing. Therefore, even if consumption of meat decreases in other countries, consumption of meat is increasing as seen in the whole earth as it is now.
