It should be noted that other parts of the forest surrounding a village are not farmed, but utilized for fishing, hunting and gathering. It would be valuable to contrast this type of farming with the clearing of large tracts of forest for plantations, ranching or farming by colonists. Clearing large areas opens up the soil to eroision and loss of fertility. The growing of single crops requires large amounts of pesticides to control specific insect and fungus populations that zero in on a single crop. In addition, growing single crops for export benefits the local people much less and provides almost no habitat for wildlife.
Profits end up going to large land owners and multinational corporations.
