What does it mean when the ocean is referred to as “life support system”? 2. “Health of the ocean means health to us.” Do you agree/disagree? Why? 3. New info learned from speech? 4. What are MPAs? 5. Sylvia Earle’s wish is to “ignite” everyone to do all they can to reach the goal of global MPAs. What do you think about that? Defend your response.Explanation / Answer
A famous poet Auden told, "Thousands have lived without love; none without water."
Ninety-seven percent of the Earth's water is ocean. If there is no ocean there is no life support system. Ocean is considered as the “World Bank", All the assets are in Ocean.
We get water, air and almost all life supporting systems from the sea. Most of the oxygen in the atmosphere is generated by the sea. Major part of the planet's organic carbon is absorbed and stored in the oceans mostly by microbes. The ocean drives climate and weather. It stabilizes temperature, shapes Earth's chemistry. Moisture from the sea develops clouds and it return to the land and the seas as rain, sleet and snow. Also the Ocean provides a shelter for around 97 percent of life in the world, maybe in the universe.
The ocean is our life support system. And to the extent in which we can reduce the stress of Ocean, then we are benefiting the way the world works, benefiting the present and the future of humankind.
Ocean is nature farmers market. Around 2.6 billion people depends Ocean as a primary source of protein. More than 90 percent of the big fish is in the sea.
In this century an ice-free Arctic Ocean may happen. It badly affects the polar bears. It also badly affects the human beings too. Surplus carbon dioxide is not only driving global warming, it's also changing ocean chemistry, making the sea more acidic. It is very bad for coral reefs and oxygen-producing plankton. We're putting millions tons of plastic and other garbage into the sea. We are blockage the ocean, destroying the planet's circulatory system, and we are taking out hundreds of millions of tons of wildlife, all carbon-based units. We also killing sharks for shark fin soup, deflating food chains that shape planetary chemistry and drive the carbon cycle, the nitrogen cycle, the oxygen cycle, the water cycle of our life support system. It is also killing bluefin tuna; truly rare and much more valuable. All of these are part of our life support system. Now industrial trawlers and draggers are graze the sea floor taking everything in their path.
The disappearance of coral and depletion of oxygen in large areas of the Pacific not only affect the creatures in the sea but it really should affect the human being.
So healthy food from ocean means the healthy world. So our help to explore and protect the wild ocean will restore the health of ocean and, in so doing, we protected whole world. So “Health to the ocean means health for us”.
Now a day’s there is a lot of changes in technology, everything is fast and we know more, but we’ve also been a loss, destruction, change. And not changes for the good. Good changes are that we now know better than ever before where the mountains are; we have better maps. Although only about 10 percent of the ocean has been mapped with the same degree of resolution that we have for the land, or the moon, or Mars, or Jupiter and much of the ocean still really is not well mapped at all.
Regulations are really seriously important to restrict in those who are more worried about their short-term gains than the benefits to society as a whole. If everyone respected the real value of taking care of the ocean, we wouldn’t need a law. But it’s helpful to have a law for those who tend to misbehave no matter what.
The Ocean, where whales, tuna and dolphins travel is the largest and least protected, ecosystem on the Earth. It is filled with glowing creatures living in dark waters and average two miles deep. It flash, shine, and glow with its own living light.
A global arrangement of action with a world conservation union, the IUCN, is started to protect biodiversity, to mitigate and recover from the impacts of climate change, to protect the high seas and in coastal areas, wherever we can identify critical places. New technologies are required to map, photograph and explore the 95 percent of the ocean that we have yet to see. The main goal of this is to protect biodiversity and to offer steadiness and flexibility.
A marine protected area (MPA) is basically a space in the ocean where human activities are more severely regulated than the surrounding waters which is similar to the parks in land. These places are given special protections for natural or historic marine resources by all authorities. Authorities differ considerably from nation to nation. So MPAs may be established to protect ecosystems, protect cultural resources such as shipwrecks and archaeological sites, or sustain fisheries production. It acts as safe heavens for marine life.These are large enough to save and restore the ocean, the blue heart of the planet.
