For quite some time, I have reflected on the ethical and enviromental imlications of modern agriculture. Finally, I decided to try a month without meat consumption, which happens to be this month. Not eating meat is not really challing thus "far". I have, however, had increasing difficulties falling asleep at night for the last ten days or so. And sleep deprivation is obviously not ok .Of course, there may not really be a causation here, but then again, I may have overlooked or underestimated some nutritional details. Has anyone had similar experiences? Or does anyone have some plausible, physiological explanations to why skipping meat could cause such problems?
