The recent trend in extreme weather, as seen in El Nino, in the drought in California, and in supertyphoons, has proven that climate change is here and that it can get worse if nothing is done.
Unnatural climate change is caused by excessive greenhouse gases, best represented by carbon dioxide (CO2) from human activity. Though a lot of CO2 emissions come from energy and transportation, food production also contributes greatly to it.
In some estimates for example, meat consumption is said to contribute to 18% of greenhouse gases.
A huge chunk of CO2 emissions can be prevented simply by switching to a non-meat diet.
There are 2 common objections to this:
- Non-meat food is not delicious
- A non-meat diet is not healthy
The first objection, being a matter of taste, is not a serious one.
It can be easily overcome by a change in mindset or by making non-meat foods more delicious.
The second objection can be overcome by either scientific proof or by actual experience.
There are many scientific studies that prove that vegetarian diets are healthy. As a vegetarian myself, the common misconception I found is that people think that vegetarians only eat leaves, which might be true for vegans but not for vegetarians.
In fact, vegetarians should eat dairy to get their Vitamin B12 and D.
The effects of vitamin deficiency can be felt as cognitive impairment which I’ve personally experienced as reduced test scores and slower math ability while I was a newbie vegetarian.
This was easily solved by taking in milk products. But if you’re a vegan, then you must take the necessary supplements.
Some people think that vegetarian diets are a relatively new trend. In reality, vegetarian diets have existed for a long time.
- India has had it for thousands of years
- England has already known it since the 18th century, as proven by Adam Smith, the founder of economics:
Smith’s biographer Rae even writes that Dr. Joseph Black, the scientist who first documented the properties of CO2, was a vegetarian:
His intake of milk is proof that dairy is important for vegetarian nutrition.
Potatoes: Probably The Best Vegetable Food for Smith
In The Wealth of Nations, Smith talks about the qualities of each major crop, favoring potatoes over oatmeal:
But potatoes are different. The chairmen, porters, prostitutes and coal-heavers in London are the strongest men and the most beautiful women in Britain.
They come from the poorest people in Ireland who eat potatoes. This proves the nourishing quality of potatoes. So we can say that, of all the basic plant-based foods, Smith advocated potatoes and wheat the most.
Indian philosopher PR Sarkar also praises potatoes for its nutrition and ease of cultivation.
Potato is one of the most common vegetable crops. It is high in carbohydrates, contains many vitamins and is very satisfying. In emergency conditions it can be eaten instead of rice.
Potato is especially beneficial when:
- little land is available for cultivation
- many people must be fed economically.
