1. A large part of agricultural land cannot be used by vegans!
Worldwide, 68% of agricultural land is so-called “permanent grassland”. This means most of it cannot be used for crops. But a person cannot digest the grass that grows there either.
Entire countries could not be vegan even if they wanted to. Keeping animals on these lands is therefore absolutely sensible and even serves to preserve valuable ecosystems!
2. Vegans eat large amounts of imported food!
Many vegans have quite a creative eating plan. But tofu, avocados, chia, bananas, kiwis, coconut milk and similar products have to be shipped halfway around the world.
Vegans often resort to exotic foods, especially in winter. Only a few are likely to limit themselves to regional, long-life foods such as pickled vegetables.
3. Vegan agriculture prevents nutrient cycles!
When vegetable products go on sale, nutrients leave the farm with them. To compensate for this, it is necessary to fertilize. But without manure, manure or manure from farm animals, it is difficult to establish an ecologically sound nutrient cycle.
It is true that a farmer can draw nitrogen from the air by growing legumes, but the same is not true of other important nutrients. So he will have to resort to large amounts of mineral fertilizer. A strong humus build-up, a basis for soil fertility, is barely possible.
4. Rainforest is being cut down for vegan foods too!
Soy cultivation in particular destroys ecosystems in their cultivation areas and threatens endangered species. In order to meet the increasing demand on world markets due to a vegan lifestyle, cultivation is done in many places without taking the environment into account.
5 Many animal products are being replaced by plastic!
Militant vegans refuse to use leather, wool or silk. The alternatives: synthetic fibers and synthetic leather. However, these are produced by petroleum products, contain plasticizers and are not biodegradable.
If by “sustainable” one understands that these substitutes will not degrade for centuries after a short period of use, then they are indeed very sustainable!
