Staple crops are plants that farmers can live on: manioc, plantains, bananas, sweet potato, pineapple, chili pepper, and others. How did you do? Can you name a crop that is conventionally grown and harvested? We've already learned about logging as a major factor, but we havn't discussed the international, national, and local factors.

Intercropping adds nutrients to the soil, prevents erosion, and provides moisture and shade to the other plants within the plot. This has been a blessing, in that, it has provided a lot of money to the country, but it has also created some problems. It is essential to addressing the need to feed a growing population and improving their nutrition. If the government provided job opportunities for these farmers, maybe they wouldn't have to resort to this type of subsistence. the crops grown are nonrenewable- after harvesting, the plot is bare again and requires cultivation (tilling and plowing of the soil), fertilization, planting, irrigation (watering), and harvesting all over again. This type of farming is declining due to pressure by environmentalists. Yes! diversity is maintained and even increased over time. In fact, farmers earn even more money through this co-op than they would through conventional Fair Trade. 617 0 obj <>/Encrypt 560 0 R/Filter/FlateDecode/ID[<110B01EEF88D794A9CC2AF853C02D941>]/Index[559 136]/Info 558 0 R/Length 216/Prev 1111338/Root 561 0 R/Size 695/Type/XRef/W[1 3 1]>>stream Rudimentary Sedentary Tillage.

You're right on the money, in more ways than one. Plants provide food for herbivores (plant-eating animals, i.e., sloths) and the herbivores provide food for carnivores (meat-eating animals, i.e., jaguars).
