Cotributers to negative impacts on underwater resources
Overfishing
Overfishing is when an aquatic creatures' population is reduced to a point where total reproduction doesn't replace the species population. Some negative impacts include the destruction of ecosystems and fiid webs, species extinction, and too much bycatch.
Chemicals used on Lawns
The chemicals used on lawns, or fertilizer, is a chemical that can raise levels of nitrogen and phosphorus in an underwater ecosystem. With high levels of these chemicals, it can create a perfect growing environment for algae, but in effect, oxygen levels can be depleted, ultimately causing whats known as a "Dead Zone."
Oil Spills
An oil spill is when large amounts of oil, or liquid petroleum, is released into an environment. When an oil spill takes place, oxygen levels are depleted, causing the death of many creatures, contributing to species extension.

Artificial Reefs
Artificial reefs are man made reefs that are meant to promote marine life in an area. These man made reefs regenerate old habitats and can bring new species to an abandoned area. Another thing is that it brings back the millions of destroyed corals body's.
Fishing Regulations
The regulating of fishing in areas and contests can still provide recreational fun to fishermen but enough fish left to reproduce and repopulate. This causes areas were fish live to be safe from over fishing and gets population to rise without risk.
Reduce Nonpoint Pollution
Non-point pollution is pollution that is not entered straight into the source. This is cause by rainfall and melting snow moving over and through the ground causing it to pick up pollutants and dragging them into the ocean. Reducing this would cause less pollution not only in the ocean but on the land too. Also reducing this would cause the ocean to be cleaner and safer for marine life to explore and live.
