Today, there is an increased awareness of environmental impacts of agriculture, with heavy criticisms made on the amount of inefficient water usage, as well as harmful pesticides, herbicides and fungicides used in farming. Many unsustainable farming methods are the source of eutrophication and soil degradation in the environment. On the other hand, farming is a necessity, and although it could be improved and made more sustainable, no one can say that we don't need farms.
