According to the Food and Agriculture Organization of the United Nations, 35% of farms worldwide are losing soil faster than it is being formed. The other options are either incorrect or incomplete. For instance, option A is incorrect because soil losses in North America have improved by 38% in cropland, but this is only since 1982, not since 1950. Option B is incomplete because while less than half of the cropland in the US and Canada is experiencing excessive rates of soil erosion, the situation may be different in other regions. Option C is incorrect because planting on the contour is a technique that can be used to control soil erosion. Option E is a matter of opinion and not necessarily a fact.
