What problems do oil spills cause?
Oil spills have huge and immediate economic, social, and environmental impacts. Local people lose their livelihoods as fisheries and tourism areas are temporarily closed; the clean up costs are enormous; and tens of thousands of marine animals and plants are killed or harmed. And the damage goes on.
What are the impacts of eutrophication and oil spills on the environment?
Eutrophication can have serious effects, like algal blooms that block light from getting into the water and harm the plants and animals that need it. If there’s enough overgrowth of algae, it can prevent oxygen from getting into the water, making it hypoxic and creating a dead zone where no organisms can survive.
How can we protect the environment from oil spills?
Establish procedures and install control measures to prevent a spill from reaching navigable water pathways: Minimize working quantities. Provide secondary containment for containers of oil that could potentially spill into the environment. Maintain a fully-provisioned, easily accessed spill kit.
Do oil spills affect humans?

What are the harmful effects of eutrophication?
Oxygen depletion, or hypoxia, is a common effect of eutrophication in water. The direct effects of hypoxia include fish kills, especially the death of fish that need high levels of dissolved oxygen. Changes in fish communities may have an impact on the whole aquatic ecosystem and may deplete fish stocks.
Why is eutrophication a bad thing?
Eutrophication is when the environment becomes enriched with nutrients. This can be a problem in marine habitats such as lakes as it can cause algal blooms. … Some algae even produce toxins that are harmful to higher forms of life. This can cause problems along the food chain and affect any animal that feeds on them.
What are the causes and effects of eutrophication?
“Eutrophication is an enrichment of water by nutrient salts that causes structural changes to the ecosystem such as: increased production of algae and aquatic plants, depletion of fish species, general deterioration of water quality and other effects that reduce and preclude use”.
