Is it realistic to live in a vegan world? What would be the pros and cons in your opinion?

For your convenience, I will summarize the article in points:

• From an environmental point of view, it would significantly reduce greenhouse gas emissions and improve public health by preventing meat-related diseases.

• The global economy, especially in the poorest countries, would suffer severely, with millions of people losing their jobs and difficulties in farming in semi-arid areas.

• It would not automatically solve world hunger and would present cultural and nutritional challenges.

• 70% reduction in greenhouse gas emissions by 2050.

• Reduction of diseases such as diabetes and heart problems.

• A vegan diet may be lacking in essential nutrients like calcium, vitamin D and B12, but a balanced one could improve your health.

I add some negative aspects: – To improve production, some cultivation methods can be used that have the effect of reducing the genetic variability of plants. This exposes them more to the attack of pathogens and they could become extinct, as happened with some varieties of banana.

• Seasonality, water and climate crises could force us to import vegetables from the other side of the world, this could increase pollution and put populations in difficulty due to the scarcity of variety (?)

• Intensive crop production in the long run causes de-fertilization of the soil, with a decrease in production yield and an increase in cost. If we do not raise animals, we should use synthetic substances.

• If we were to depend on other nations to supply some food, given the variability of geopolitical relations, could there be negative repercussions on food supply and health if some types of food were missing?
