growing demand for food by the world’s population. Yields of primary crops such as rice and wheat increased dramatically‚ the price of food declined‚ the rate of increase in crop yields generally kept pace with population growth‚ and the number of people who consistently go hungry was slightly reduced. This boost in food production has been due mainly to scientific advances and new technologies‚ including the development of new crop varieties‚ the use of pesticides and fertilizers‚ and the construction

usually put in crops to make them bigger‚ tastier‚ or healthier. Though this sounds like a great idea there are extreme drawbacks. For instance GMOs are already increasing herbicide use in the U.S. by 26 percent since 1998 when the leaders of GMOs said that they would decrease herbicide use. This also means that more weeds are becoming resistant to herbicides and so GMOs are creating superweeds that are even harder to kill. With the constant spraying of herbicides on our GMO crops the herbicide chemicals

The Bahamas has no real soil profile. It is shallow‚ does not retain fertility or water‚ and is always thin‚ patchy or stony. This is a problem because the crops will not grow properly and the soil will be of no use to farmers. Our soil is infertile because it has been overworked by earlier generations‚ and it doesn’t get all of
