Ocean living: A step closer to reality? The 1995 film Waterworld was one of Hollywood's most infamous budget busters oe a mega-million-dollar post-apocalyptic thriller that,
More importantly, it may also have helped do the same to the idea of mankind living on the sea.
Though scientists aren't predicting sea-level rises of the magnitude seen in Waterworld oe hundreds of feet thanks to melting polar ice caps oe we may have to plan for a world with much higher sea levels.
or at least some of us, will live on the ocean. Designer and architect Buckminster Fuller saw cities at sea contributing to a sustainable future for humanity.

Today, some 7, 000 Tankas still maintain a sea farming life oe possibly a preview of a future to come for many more of us.
We see signs that a"blue revolution  in ocean harvesting technology is underway, suggesting floating cities can't be far off.

it's not far-fetched to imagine hundreds of these plants grazing the high seas, trading abundant seafood surpluses with cities on land.
Shell's example demonstrates the long-lived feasibility of living on the sea. In fact, most fundamental challenges of living safely on the ocean have been solved by offshore drilling
or shipping companies (cruise lines got satellite internet years ago, while most of Asia and Africa still lack it).
Free floatingthe Seasteading Institute has also been dealing with the challenges faced by communities trying to live permanently on the ocean.

the logistical challenges needed allow a community to live on the high seas can be solved one at a time. British designer Phil Pauley has developed a concept for a sea habitat comprising interconnected spherical modules that could submerge during storms

The US Fish and Wildlife Service proposed on 22 october to designate around 500,000 square kilometres of critical habitat 96%of which is sea ice for the polar bear.

and oceans to futuristic'solar-radiation management'techniques for example, creating haze in the stratosphere to act as a cheap layer of sunscreen.
Another cadre of researchers is pushing a more benign technology that involves seeding clouds with sea salt to increase their brightness.
The technique could be focused on regional problems such as disappearing Arctic sea ice say advocates, who suggest that a research programme could be presented to the intergovernmental Arctic Council for approval.
Susan Lieberman, director of international policy for the Pew Environment Group in WASHINGTON DC, says the agreement showed that management of high seas fisheries was flawed and inadequate.
and Wildlife Service has set aside roughly 484,000 square kilometres in Alaska and the surrounding seas as a'critical habitat'for the polar bear (Ursus maritimus),
Almost all of the protected area is sea ice off Alaska's northern and western coasts.
and large areas of ocean and coastlines are polluted. What role should the federal government play domestically
and through foreign policy to protect the environmental health and economic vitality of the oceans? We are directing additional funding to Gulf Coast restoration to bring back the fisheries and coastal ecosystems
These are significant steps that are helping us improve the health of our oceans and build more robust fisheries.

Overfishing of the oceans is a real problem. Aquaculture is improving rapidly to address those concerns.
Beyond that is being absorbed into the oceans and raising the ppm of the atmosphere. Both are warming.
As for the free carbon acidifying the ocean why would that be worrying? The acidity is neutralized by the dissolution of Calcium
which gave them an advantage over the various shellfish that dominated earlier oceans). Likewise when that carbon is needed that calcium will be freed up once again.
For the past few years Terrill's team has used a Remus to study the ocean circulation around Palau.

°The top layers of the oceans would freeze over but in an apocalyptic irony that ice would insulate the deep water below
and prevent the oceans from freezing solid for hundreds of thousands of years. Millions of years after that our planet would reach a stable âÂ#Â00°the temperature at which the heat radiating from the planet's core would equal the heat that the Earth radiates into space explains David Stevenson a professor of planetary science at the California Institute of technology.
Humans could live in submarines in the deepest and warmest parts of the ocean but a more attractive option might be nuclear-or geothermal-powered habitats.
because the oceans tides are managed no longer by the gravitational pull of the Moon. There will also likely be massive tsunami's as a result of the earthquakes.

About 85%of the oxygen comes from the oceans. Every time you throw away a napkin
For example trash in the ocean is not the same argument when addressing manmade climate change.
We understand how oceans absorb the CO2 and acidify. We understand that global warming is creating thermal expansion of our oceans.
These things are facts. Oh but it's not us doing it. We have to be arrogant to think we could affect our big ol'planet.

Puckett estimated that just more than half of the material processed in Guiyu actually got recycled judging from the tons of plastic leaded glass and burned circuit boards discarded near waterways and in open fields.

In the GCEP report Field and lead author Jennifer Milne describe a suite of emerging carbon-negative solutions to global warming--from bioenergy technologies to ocean sequestration.
The report also explored the possibility of sequestering carbon in the ocean with a particular focus on the problem of ocean acidification
Ocean acidification results from the increased uptake of atmospheric CO2 which causes seawater to become more acidic.
and other minerals could be added to the ocean to reduce acidity and sequester atmospheric CO2 absorbed in seawater.
Although the potential for CO2 sequestration in the ocean is associated large the risks to the marine environment need to be assessed adequately the authors concluded.
and through clever engineering we've taken its capabilities a step further says lead author Mathias Kolle a postdoctoral fellow at the Harvard School of engineering and Applied sciences (SEAS).

The researchers evaluated the idea of adding iron to oceans in order to stimulate the growth of algae
because less than a quarter of the algae could be expected to eventually sink to the bottom of the ocean which would be the only way that carbon would be sequestered for a long period of time.
The study predicted that the rest would be expected to be consumed by other sea life that respire carbon dioxide
Sunlight hits the ocean heats it up and energy has to leave the ocean through evaporation he explained.

And there are a lot of plants in the U s. on the sea taking advantage of that. But there's also the environmental concern in putting warmer water back into the ocean--the long-term fate of the ecology of the ocean.

like finding way to desalinate sea water cheaply and easily. If we did that we would not have to worry about depleting aquifers
because it would take us a very long time to deplete all the water in the oceans.
The good news is that we â â¢ve been dealing with sea level rise and weird weather for most of human history.

There are projects testing out the possibility of seeding the ocean with iron; this is a fertilization scheme.
Ocean plankton are one of the biggest CO2 sucks on the planet, and if you fertilize them there might be more blooms.
Unlike corn or even sugar ethanol, halophyte algae (algae that grow in saltwater) do not compete with food stocks for freshwater. oewhen the cost of pumping ocean water into so-called wasteland regions such as the Sahara
halophyte algae farmers could use solar-powered pumps to move water up from sea level or even up from underground aquifers such as the Nubian sandstone aquifer system that sits beneath desolate regions of Libya, Chad, and Sudan.
Tidal-current turbines and tidal-stream turbines tapping the power of sea systems like the Gulf stream could provide energy for power-hungry states such as Florida.
