Answer 2

1)

One example of a pollutant affecting oceans is plastic. Plastics can kill marine life

Agricultural runoff contaminates freshwater and leads to eutrophication

Air is contaminated by sulfur oxides leading to acid rain

Land is polluted by persistent organics which can be transmitted along the food chain.

2) Deforestation removes the protection of the soil from erosion and the same is true for overgrazing

The resources of Earth have been negatively impacted by numerous pollutants. Ocean plastic pollution endangers marine life, upsets ecosystems, and contaminates seafood, which can have an impact on human health. Pesticides from agriculture leak into freshwater supplies, harming aquatic life and degrading the quality of the water.

Air quality is impacted by sulfur dioxide emissions, which also cause respiratory problems and acid rain. Pesticides and other industrial chemicals are persistent organic pollutants that contaminate soil, endangering plants and making their way into the food chain.
