2. Describe how improper agricultural practices and solid waste disposal may impact fresh water and marine ecosystems.
Improper agricultural practices, such as over-fertilization, can lead to an increase in the amount of nutrients in the water, such as nitrogen and phosphorus. This can cause an increase in the growth of algae and other aquatic plants, leading to a decrease in oxygen levels in the water. This can cause a decrease in the number of fish and other aquatic organisms, as well as an increase in the number of harmful bacteria.
Solid waste disposal can also have a negative impact on fresh water and marine ecosystems. Solid waste can contain pollutants such as heavy metals, pesticides, and other chemicals that can be toxic to aquatic organisms. These pollutants can accumulate in the water and can be ingested by fish and other aquatic organisms, leading to health problems and even death. In addition, solid waste can also block sunlight from reaching aquatic plants, leading to a decrease in photosynthesis and a decrease in oxygen levels in the water.
