Crops of fruits and vegetables are important for a healthy diet, but the fertilizers and pesticides used to protect them can pollute local water sources. Fertilizers contain nitrates, and some pesticides contain carbamates; both of these chemicals can be toxic. Each time it rains, the chemicals from farms run into nearby lakes and rivers. Science can provide evidence of water pollution and maybe stop the use of these chemicals near sources of water. But how will this affect the farmers or food resources in the area?

How do temperature and salinity affect deepwater currents? as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
