I found this video pretty interesting...
https://www.youtube.com/watch?v=dVv597m848s
It shows a 14 year old girl using a scythe to mow the grass. It also shows how the future of agriculture is going to be like. We are going back to handtools and animal power in the future when oil runs out.
Without fossil fuels, like oil and natural gas, most of the population will have to become farmers again in order to feed the entire population. There is no way only 2% of the population is farmers to support the rest of the population when oil is gone. The only reason 2% of the population can support the rest of the population with food is because of fossil fuels.
So you better start using a horse/oxen and handtools on your farm in the near future for growing food. You have no other choice because tractors and combines don't work without oil.
Anyways that is all I have to say. I have to go to class soon.
