As billions of people depend on oceans for their livelihood and food source, increased efforts and interventions are needed to conserve and sustainably use ocean resources at all levels. Ocean acidification is caused by the uptake of atmospheric CO2 by the ocean, which changes the chemical composition of the seawater.

Why Is the Ocean Important. The Ocean is a vital lift support system. Everything that we rely on in our day to day lives leads back to it. The Ocean is the foundation of all life, an extraordinary and largely unexplored place, teeming with fascinatingly diverse plants and animals which, together with currents and natural systems, shape our planet.
Jan 29, 2024 · Covering over 70% of our blue planet and holding roughly 97% of the world’s water, the Ocean provides the foundation for all living things. From the smallest plankton to the largest animal to have ever lived (the blue whale). And that’s just the beginning of why the Ocean is important. Energy is cycled across its single, interconnected ...

NPS pollutionis the result of land runoffs, precipitations, and atmospheric deposition. With rainfall or snowmelts moving through the ground, the pollutants they pick up and transport are eventually deposited into lakes and rivers, which then carry them all the way to the ocean. Nonpoint source pollution can include: 1. Excess fertilizers, herbicid...
Intentional discharge is caused by humans deciding that the best place to dump toxic chemicals and debris are our waterways. Direct dischargeinclude: 1. Toxic waste from industrial plants 2. Sewage materials passed directly to the ocean 3. Deliberate discharges from oil tankers that do not respect regulations 4. Trash discarded into the water, most...
Oil and chemical spills are point source pollution, because they come from a single source. Those resulting from damaged or faulty facilities are also considered a type of point source pollution. These events are typically caused by accidents and can have an extremely destructive impact on the surrounding environment. Fortunately, they do not happe...
Trash in the ocean and waterways is an effect of littering in general, even if far inland, and not only the result of debris directly thrown into the sea: water discharge systems bring inland waste all the way to the ocean. Marine debris comes from human beings, whether through land or ocean-based sources. Common examples of marine debris can be pl...
Deep-sea mining consists in thedrilling of the ocean’s floor to extract materials such as gold, silver, copper, and zinc. This activity is devastating for the balance of the deepest levels of the sea, most of which is still unexplored. It does not only destroy habitats and ecosystems, but also leads to the creation of sulfide deposits,whose harmful...
- The air we breathe: The ocean produces over half of the world's oxygen and absorbs 50 times more carbon dioxide than our atmosphere.
- Climate regulation: Covering 70 percent of the Earth's surface, the ocean transports heat from the equator to the poles, regulating our climate and weather patterns.
- Transportation: Seventy-six percent of all U.S. trade involves some form of marine transportation.
- Recreation: From fishing to boating to kayaking and whale watching, the ocean provides us with many unique activities.
Jan 4, 2018 · The Ocean is the heart of the planet. Water covers more than two-thirds of the Earth’s surface. Sea plants, like Posidonia, produce 70% of the oxygen we breathe (1), and the deep waters are home to wildlife and some of the biggest creatures on earth. It provides us with food, jobs, life, entertainment, and sailing! Without it, we cannot survive.

Aug 29, 2019 · 2. It helps regulate the climate. The ocean absorbs huge amounts of heat from the sun. “More than 90% of the warming that has happened on Earth over the past 50 years has occurred in the ocean,” according to the US National Oceanic and Atmospheric Administration. That heat tends to be at its most intense nearer the equator, with the water ...
