Save the Oceans

To Save the Planet, Save the Seas

FOR the many disappointments of the recent climate talks in Copenhagen, there was at least one clear positive outcome, and that was the progress made on a program called Reducing Emissions From Deforestation and Forest Degradation. Under this program, key elements of which were agreed on at Copenhagen, developing countries would be compensated for preserving forests, peat soils, swamps and fields that are efficient absorbers of carbon dioxide, the primary heat-trapping gas linked to global warming.

This approach, which takes advantage of the power of nature itself, is an economical way to store large amounts of carbon. But the program is limited in that it includes only those carbon sinks found on land. We now need to look for similar opportunities to curb climate change in the oceans.

Few people may realize it, but in addition to producing most of the oxygen we breathe, the ocean absorbs some 25 percent of current annual carbon dioxide emissions. Half the world?s carbon stocks are held in plankton, mangroves, salt marshes and other marine life. So it is at least as important to preserve this ocean life as it is to preserve forests, to secure its role in helping us adapt to and mitigate climate change.

Sea-grass meadows, for example, which flourish in shallow coastal waters, account for 15 percent of the ocean?s total carbon storage, and underwater forests of kelp store huge amounts of carbon, just as forests do on land. The most efficient natural carbon sink of all is not on land, but in the ocean, in the form of Posidonia oceanica, a species of sea grass that forms vast underwater meadows that wave in the currents just as fields of grass on land sway in the wind.

Worldwide, coastal habitats like these are being lost because of human activity. Extensive areas have been altered by land reclamation and fish farming, while coastal pollution and overfishing have further damaged habitats and reduced the variety of species. It is now clear that such degradation has not only affected the livelihoods and well-being of more than two billion people dependent on coastal ecosystems for food, it has also reduced the capacity of these ecosystems to store carbon.

The case for better management of oceans and coasts is twofold. These healthy plant habitats help meet the needs of people adapting to climate change, and they also reduce greenhouse gases by storing carbon dioxide. Countries should be encouraged to establish marine protected areas ? that is, set aside parts of the coast and sea where nature is allowed to thrive without undue human interference ? and do what they can to restore habitats like salt marshes, kelp forests and sea-grass meadows.

Managing these habitats is far less expensive than trying to shore up coastlines after the damage has been done. Maintaining healthy stands of mangroves in Asia through careful management, for example, has proved to cost only one-seventh of what it would cost to erect manmade coastal defenses against storms, waves and tidal surges.

The discussions in Copenhagen have opened the way for all countries to improve the management of oceans and coasts to harness their immense potential to mitigate climate change ? especially over the next decade, while the world?s politicians, scientists and engineers develop longer-term strategies for stabilizing the atmospheric concentration of greenhouse gases.

In their continuing negotiations on climate change, nations should now make it a priority to produce a single map of the world that documents all the different types of coastal carbon sinks, and identify the ones that are in most immediate need of preservation. New studies should be undertaken to better understand how best to manage these areas to increase carbon sequestration. Then, following the example of the forests program, it will be possible to establish formulas for compensating countries that preserve essential carbon sinks in the oceans.

We urgently need to bring the ocean into the agenda alongside forests so that, as soon as possible, we can help the oceans to help us.

MONETIZING THE CARBON PROBLEM

Overpopulation is the gravest problem.

The "inconvenient truth" overhanging the UN's Copenhagen conference is not that the climate is warming or cooling, but that humans are overpopulating the world.

A planetary law, such as China's one-child policy, is the only way to reverse the disastrous global birthrate currently, which is one million births every four days.

The world's other species, vegetation, resources, oceans, arable land, water supplies and atmosphere are being destroyed and pushed out of existence as a result of humanity's soaring reproduction rate.

Ironically, China, despite its dirty coal plants, is the world's leader in terms of fashioning policy to combat environmental degradation, thanks to its one-child-only edict.

The Numbers:

-If only one child per female was born as of now, the world's population would drop from its current 6.5 billion to 5.5 billion by 2050, according to a study done for scientific academy Vienna Institute of Demography.

-By 2075, there would be 3.43 billion humans on the planet. This would have immediate positive effects on the world's forests, other species, the oceans, atmospheric quality and living standards.

-Doing nothing, by contrast, will result in an unsustainable population of nine billion by 2050.

Humankind must recalibrate its behavior to account for the fact that the world can only accommodate so many people.

The fix is simple.  And yet  this is not on the agenda in Copenhagen.  No other solution will work unless population control is imposed.

China has proven that birth restriction is smart policy. Its middle class grows, all its citizens have housing, health care, education and food, and the one out of five human beings who live there are not overpopulating the planet.

The only fix is if all countries drastically reduce their populations, clean up their messes and impose mandatory conservation measures.
