First of all, despite the question, I believe that people should follow what we always been doing and not to change just because. However, if I had to choose, I think eat at a lower trophic level would be more beneficial to humans. Now days, people are usually eaten higher on the food chain, but this could be not as efficient environmentally. As the trophic level goes up, 90% of the energy will be lost which means that we are only getting 10% of our food’s energy, the rest are being used to make heat. One of most commonly used example would be beef. Cows eat grass, and we eat cows. 90% of energy will be lost from grass to cow, and we are receiving 10% of cow’s energy. If we just decided to eat grass (vegetables), we will gain much more energy.
