What if the whole world went Vegetarian?

Have you ever thought what would happen if the whole world went vegetarian? will that bring any benefit to the humanity? I am gonna answer this question in this post. though, it is quite clear that whole world is not about to stop meat eating. still, it’s worth noting the changes after the whole world goes vegetarian may come. Recently there was a quite interesting article in The World Economic Forum. it analyses the situation in a holistic way.

Energy Intensive:

One of the most frequently mentioned environmental costs of eating meat is the CO2 involved in producing it. Compared to fruit and vegetables, the amount of CO2 released by the production of meat is remarkably high.

According to Scientific American, producing half a pound (226g) of potatoes emits the same as driving a small car 0.17 miles (0.2km). Half a pound of beef emits as much as driving the same car 9.8 miles (12.7 km).


hence we can see that how much energy would be saved if people stop eating meat. it may impact the world’s economically significantly.

The study estimated both the health and climate change impacts of moving towards more plant-based diets for all major regions of the world.

Healthier Planet, healthier World:

Researchers looked into the environmental and healthcare benefits that would be felt by 2050 in three scenarios.

The first looked at the world’s population following global guidelines on healthy eating (HGD), the second at the world becoming vegetarian (VGT) and the third, vegan (VGN).


Water use:

The amount of water needed to produce meat is another major environmental cost. On this chart, only butter (another animal product) and nuts can match the thirst of animals raised for meat.

What about the people?

is it all good news? Are there any losers in this scenario?
“There are over 3.5 billion domestic ruminants on earth, and tens of billions of chickens produced and killed each year for food,” Ben Phalan, who researches the balance between food demand and biodiversity at the University of Cambridge, told the BBC. “We’d be talking about a huge amount of economic disruption.”


While retraining and government subsidies could help many former livestock-related employees, significant unemployment and social upheaval would be inevitable, especially in rural communities.

And parts of the world which currently support livestock would be able to support crops instead.
Is there any loss to the environment:

Some experts have also highlighted that ending meat consumption would not be all good news for the planet, either.


The BBC reports that in the past, when parts of the Sahel, an area south of the Sahara in Africa, have been converted from livestock pasture to croplands, the result was desertification.

The reality:

Of course, the world is not about to give up meat. In fact, with the growth of the middle class in countries like India and China, more meat is being consumed than ever before.

There is, though, clearly much to be learned from imagining a meat-free world which could help tackle aspects of man-made climate change.

The key, as parents around the world have been telling their children for millennia, is moderation.

If we can cut down meat production, it not only benefits our health but that of the planet as well while also helping in the fight against climate change.
