What are the abuses of the ocean?
Global warming is causing sea levels to rise, threatening coastal population centers. Many pesticides and nutrients used in agriculture end up in the coastal waters, resulting in oxygen depletion that kills marine plants and shellfish. Factories and industrial plants discharge sewage and other runoff into the oceans.
What are 5 major resources from the ocean?

What are the threats to the ocean environment?
Oceans are damaged every day by oil and gas drilling, pollution, and industrial impacts. Human activities are changing the ocean’s chemistry, destroying habitats, and killing marine life. NRDC has pioneered ways to restore and protect our oceans from destructive practices.
What causes ocean pollution?
Causes of pollution include oil (35% from city runoff), agriculture pesticides and fertilizer runoff, garbage misplacement, and mining. Pollutants can be prevented with the proper care of ships, tankers, and drilling. Recycling and pesticide alternatives can help make sure products don’t get into the world’s oceans.
Where are most ocean resources found?
Many minerals can be found within the continental shelf and the deep ocean floor. High organic activity occurs in the water above the continental shelf and sediment accumulates on the ocean floor. The continental shelf contains several resources such as oil, phosphorite, manganese, gold, tin, diamonds, and titanium.

What are the types of ocean pollution?
Here’s a breakdown of the four most common varieties of marine pollution and the harmful effects they can have on marine populations.
- Plastic pollution.
- Light pollution.
- Noise pollution.
- Chemical pollution.
Is it possible to overuse ocean resources?
Overuse of ocean resources is caused by the market growing and the demand for oil, minerals, gas etc. These companies are the cause of the overuse.
What are the 3 types of marine resources?
Generally, marine resources are divided into three categoriesg., biotic resources, abiotic (mineral and energy) resources and commercial resources (navigation, aviation, trade and transport etc.). On an average, marine resources are also classified into living resources and non-living resources.
What are resources of the ocean?

One of great ocean natural resources is the coral reefs. Coral reefs are the rocky mound which is the accumulation form of calcium carbonate in the sea. They are found in many parts of the world, usually in shallow areas. There are three types of coral reefs, there are fringing reefs, barrier reefs, and atolls.
How does overfishing affect the ocean?
Around the globe, some areas are even extremely dependent on fish for economic reasons. If overfishing depletes the ocean of most of its fish, many areas could face severe economic problems, along with threatened food supplies.
