Farms today take up a lot of space, and with a growing population, major deforestation would have to occur to feed all those hungry people. Conventional farms also use lots of pesticides, herbicides and fertilizers, which can contaminate both land and water. Then there's always the chance some pests or nasty weather will blow in and cause crop failure, or the soil will become depleted from overuse. All in all, farming is an uncertain endeavor.
