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.
Why should we care about the ocean?
A healthy
ocean regulates climate and reduce climate change impacts
. Ocean currents distribute heat across the globe, regulating temperature and weather. The ocean also absorbs over 90% of the heat and approximately 30% of carbon dioxide emissions produced by human activities.
Why is it so important to save the ocean?
“
Protecting the ocean from plastic pollution in our country boosts tourism and promotes clean water and sanitation
.” “A healthy ocean regulates climate and reduces the effects of climate change. Ocean currents distribute heat across the globe, absorbing over 90% of the heat and 30% of the C02 emissions produced by us.

What will happen if we don't protect our oceans?
By 2030, half of the world's oceans will already be suffering from
climate change
, which will have catastrophic consequences for marine life. Hotter water temperatures mean that there'll be less oxygen in the water, so many animals won't be able to live in their current habitats and be forced to migrate.
How do humans benefit from the ocean?
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.
How do humans impact the ocean?
Habitat Destruction
Virtually all Ocean habitats have been affected in some way via
drilling or mining
, dredging for aggregates for concrete and other building materials, destructive anchoring, removal of corals and land “reclamation”.
What are the uses of ocean water?
Ocean waters serve
as a source of food and valuable minerals
, as a vast highway for commerce, and provide a place for both recreation and waste disposal. It has been estimated that as much as 10% of human protein intake comes from the oceans.
How much oxygen does the ocean produce?
At least half of Earth's oxygen
comes from the ocean.
The surface layer of the ocean is teeming with photosynthetic plankton. Though they're invisible to the naked eye, they produce more oxygen than the largest redwoods. Scientists estimate that 50-80% of the oxygen production on Earth comes from the ocean.
Why is ocean water salty?
Salt in the sea, or ocean salinity, is
mainly caused by rain washing mineral ions from the land into water
. Carbon dioxide in the air dissolves into rainwater, making it slightly acidic. … Isolated bodies of water can become extra salty, or hypersaline, through evaporation. The Dead Sea is an example of this.
Who protects our oceans?
EPA
helps shape U.S. Government positions on international marine pollution issues, protecting U.S. environmental and economic interests throughout the world's oceans.
Why oceans do not freeze?
The high concentration of salt in ocean water lowers its freezing point
from 32° F (0° C) to 28° F (-2° C). As a result, the ambient temperature must reach a lower point in order to freeze the ocean than to freeze freshwater lakes.
How can we stop plastic pollution?
- Wean yourself off disposable plastics. …
- Stop buying water. …
- Boycott microbeads. …
- Cook more. …
- Purchase items secondhand. …
- Recycle (duh). …
- Support a bag tax or ban. …
- Buy in bulk.
Is the ocean in danger?
Ocean Threats. …
Human activities are threatening the health of the world's oceans
. More than 80 percent of marine pollution comes from land-based activities. From coral bleaching to sea level rise, entire marine ecosystems are rapidly changing.
What will happen to the ocean in 2050?
Experts say that by 2050
there may be more plastic than fish in the sea
, or perhaps only plastic left. Others say 90% of our coral reefs may be dead, waves of mass marine extinction may be unleashed, and our seas may be left overheated, acidified and lacking oxygen. It is easy to forget that 2050 is not that far off.
What would happen if our oceans died?
Paul Watson: The reality is that if the ocean dies, we die – because the
ocean provides all of those things which make it possible for us to live on the planet
. … If phytoplankton disappear, we disappear also, we can't live on this planet without phytoplankton.
