“Everyone must be vegan by 2030. Otherwise, life on Earth will be unsustainable.” To me, this idea seems neither realistic nor feasible. The biggest reason why I think this way is that the main factor behind this idea is the incredibly rapid population growth. What I mean is that in the natural state of the ecosystem, humans are omnivores. Therefore, there is no inherent harm in consuming animal-based food.
The real problem we face is not our diet, but the collapse of the ecosystem, which cannot renew itself due to the reckless consumption by a rapidly growing population. If there is an issue that needs to be addressed, it should be population growth, not our diet. In short, controlling population growth and guiding people towards sustainable consumption seem much more realistic than forcing everyone to adopt a vegan diet.
I sincerely believe that in the next six years, until 2030, there will be significant progress in population control and conscious consumption. However, the idea that everyone will become vegan in such a short period neither seems right nor healthy to me. In any case, if we do not start addressing this issue urgently, the end of our species—and possibly even the world—seems very near.
