Without healthy oceans, our life on Earth would be severely challenged, unpleasant and perhaps impossible. The oceans are the life support system of all living beings. That's because life on Earth can thrive without land, but
it cannot exist without an ocean
.
What would happen without the ocean?
Well, without the oceans,

Why do we need the ocean to survive?
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.
Will we die if the ocean dies?
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. Over 70% of the oxygen is actually produced by phytoplankton in the ocean, and since the 1950 there's been a 40% diminishment in phytoplankton population.
What do humans get from the ocean?

.
Is the ocean healthy?
A healthy ocean is
a prerequisite for a healthy planet and healthy human communities
. Eighty per cent of all life on Earth is found in the ocean. It is the world's biggest biosphere and home to great biological and carbon pumps and food webs that control our climate and sustain us all.
What is killing our oceans?
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 is destroying the ocean?
In conclusion, the main human threats to marine life are
shark hunting, overfishing, inadequate protection, tourism, shipping, oil and gas, pollution, aquaculture and climate change
. These are activities that cause fish and plants in the aquatic habitat to become extinct.
What is the biggest threat to the ocean?
Plastic pollution
is currently the biggest threat to the ocean – Stop Talking Trash about Marine Litter.
Will there be fish in 2050?
An estimated 70 percent of fish populations are fully used, overused, or in crisis as a result of overfishing and warmer waters. If the world continues at its current rate of fishing,
there will be no fish left by 2050
, according to a study cited in a short video produced by IRIN for the special report.
