Whether the agriculture practiced was the '; Text[1]=' of crops or the taking care of '; Text[2]=', the consequences of the agricultural revolution would be profound.

Probably the most important impact of agriculture on human health was that it introduced a '; Text[3]=' to animals. Living with cows, chickens or even dogs, humans were exposed to the '; Text[4]=' that these animals carried. Back in their hunting and gathering days, humans were only ever exposed to animals for very '; Text[5]=' bursts of time. With the '; Text[6]=' of animals and the building of farms, humans lived side by side with animals for 365 days a year. It became much easier for micro-organisms to pass from one species to the other.

The loss of a '; Text[7]=' lifestyle was also important, hygiene became an issue. Pollution of nearby '; Text[8]=' sources would became important. As was the issue of where to go to the toilet. These were problems that did not concern nomads.

Another major impact of the agricultural revolution is that it allowed higher '; Text[9]=' densities to live in a smaller area. Especially, when agricultural surpluses led to the formation of towns and '; Text[10]='. The higher the population density became, the larger the potential reservoir of '; Text[11]=' was for the micro-organisms that carry diseases.

Of course, the agricultural revolution also brought many advantages, not least the '; Text[12]=' of food.
