Agriculture is changing the environment. With increased populations, there is a greater demand for food. Which of the following is not an impact of farming? A) pesticide and fertilizer pollution B) sediment transport and deposition downstream C) increased water supply and flooding D) desertification and deforestation

The answer is D) desertification and deforestation

To know the answer you can rule out the non-possibilities. A is not correct because farmers use them all the time. B is not correct because water and pesticides can flow downstream and carry and deposit sediment. C is not correct because farmers can flood their own farms. When they plant things and a food comes, all of those plants will die or their roots will detach which lowers the food that can be sold. D is correct because farmers don't farm in the desert or the forest, so it would not be an impact of farming.
