In the article: The Agricultural Revolution as Environmental Catastrophe: Implications for Health and Lifestyle in the Holocene by: Clark Spencer Larsen, It explains about the drastic changes in the Earths landscapes s as forests give way to agricultural land, and the resulting environmental degradation, loss of species, and other disasters. Along with these negative changes to the landscape there was a decline in the health and quality of life in humans. Skeletal evidence indicates that these impacts on health were immediate—as soon as humans began to farm, health conditions declines due to population crowding, workloads, and increased nutritional deﬁciencies. Looking at the different health indicators, there is variability. For example, some agriculturalists show far more skeletal evidence of iron deﬁciency anemia, and rice agriculturalists may be less prone to dental caries. Taken as a whole, farming had positive and negative aspects—it provided food for a growing world population, but with negative consequences for the health and wellbeing. These negative consequences have been improved today in developed nations, made possible by advances in medical care, varied and nutritional diets, and strict sanitation and water treatment laws. At no other time in the history of our species has there been so much nutritional deﬁciency, crowd-related infections, infant mortality, and poor health generally. The situation did not improve. In the next couple of decades, farmers had to provide food for nearly 8 billion people, nearly a 40% increase. Most of the growth in population will be in developing countries whose ability to produce the food necessary for the survival of all is diminishing. Clearly, the change in how humans acquired food in a few centuries 10,000 years ago has now overcome much of the world.
