Answer:
Much of this runoff flows to the sea, carrying with it agricultural fertilizers and pesticides. Eighty percent of pollution to the marine environment comes from the land. One of the biggest sources is called nonpoint source pollution, which occurs as a result of runoff. The majority of pollutants that make their way into the ocean come from human activities along the coastlines and far inland. One of the biggest sources of pollution is nonpoint source pollution, which occurs as a result of runoff. Around the world, agriculture is the leading cause of water degradation. In the United States, agricultural pollution is the top source of contamination in rivers and streams, the second-biggest source in wetlands, and the third main source in lakes.The most polluted ocean in the Pacific with 2 trillion plastic pieces and one-third of the plastic found in this ocean circulates in the North Pacific Gyre.
Explanation:
Less tilling thanks to genetically modified herbicide-tolerant crops also means that farmers spend less time on their tractors, using less fuel and reducing carbon emissions. Conservation tillage enabled by genetically modified crops has reduced greenhouse gas emissions on farms globally and can help farmers adapt to and mitigate climate change. In fact, in 2014 5.2 billion pounds of atmospheric carbon dioxide emissions were reduced by conservation tillage and decreased fuel use made possible by genetically modified crops. That’s equal to removing nearly 10 million cars from roads for one year.
According to the USDA, adopting conservation tillage can save at least 3.5 gallons of fuel per acre for farmers who would spend less time on their tractors, reducing emissions. If all of the corn planted in the U.S. (non-genetically modified and genetically modified combined) in 2015 was grown with conservation tillage methods, nearly 308 million gallons of fuel would be saved, equivalent to preventing 6.9 billion pounds of carbon emissions.
