The way to reduce carbon: Cultivate the algae of shellfish on a large scale
Leaderette:

This week is on the occasion of the annual scientific and technological festival of Shanghai, the theme of this year is that " science and technology creates bright life " . The ones that pay close attention to power saving, sustainable development in the whole society rely on the scientific and technical means instantly, let the intersection of life and low carbon, " the bright life " Question hit and should have righteous. Likewise, recommend saving the low carbon life ideas of energy resources, ecological environment protection, also it popularizes the focal point of the work that the science spreads. This newspaper will put out one group from today " Make the intersection of life and low some " carbon Series of reports,from bit of daily life,it excavate low that carbon live for possibility, also hope to bring some to reader to inspire.

If you love the edible shellfish's seafood, while enjoying table delicacies, you may be making a contribution to low carbon cause. Held yesterday " The low carbon way " On the salon in environment protecting mode, the expert has proposed brand-new " marine carbon is gathered together " Concept. Expect? Unattractive marine organisms such as the alga, shell,etc., it is " reduces the carbon past master " with strong ability .

The ocean reduces the big carbon potentiality

The question of varying with global climate is paid close attention to day by day, low carbon idea taking reducing the carbon dioxide content of the atmosphere as goal, become the topic that all circles discuss warmly. According to technological angle, reduce carbons to discharge except through the measure of saving energy and reducing the cost etc. at present, it is quite important too that carbon catches technology, two kinds including industrial means and biological means, gathering together in the forest carbon is a kind of riper firm carbon law of living beings.

Tang QiSheng, academician of Chinese Academy of Engineering, specializes in carbon in the ocean and catches potentiality in recent years. He finds that second biological carbon gathers together resources to regard ocean as the forest, have scientific possibility. "Research proves, the human activity discharges 5,500 million tons of carbons every year, among them the ocean absorbs 20%-35%, it is probably 2 billion tons. " Tang QiSheng says. According to the report of the United Nations " blue carbon ", biological carbon exceeding half on the earth is caught and finished by the marine organism, including planktonic organism, marine alga, the intersection of salt marsh and plant and mangrove, shellfish too can seal carbon in the ocean up for safekeeping through calcification, the intersection of living beings and the intersection of person who deposit and course, and seal time up for safekeeping and reach QianNian.

"So, the ocean has ready conditions to become an enormous firm carbon container, develop ' carbon gathers together fishery ' and have strategy value alone. " QiSheng Tang explain carbon remit fishery mean promoting aquatic living beings to absorb the carbon dioxide in the the water bodies through the fish production activity, if the cultural method is apt, this course will improve the water body and absorb the ability of carbon dioxide in the atmosphere.

The shellfish catches the carbon ability strongly

The east sea area fishing political situation chief Li FuRong of the Ministry of Agriculture reveals, they the intersection of island and peripheral sea area build, remit fishery experimental area by one new marine the intersection of pasture and demonstration area and carbon extremely east the east of sea area at present, on one hand, through popularizing the ecological cultural method, controlling cultivating the density, change the old method excessively caught, let the fisherman turn into " Herdsman " ,It is more greatly and eating the safer hairtail to offer stature to citizen; On the other hand, key research large-scale alga and firm carbon ability of the shell, this is one of the main tasks too.

The data show, it helps carbon in the light sea area land to catch that the large-scale algae of shellfish is cultivated, especially the shell, there are quite a few and is solidified its carbon absorbed in the shell, will not get back to the atmosphere again in quite long time. After reaping a batch of shellfishes, can also continue cultivating new a batch of shellfishes, continues " sucking carbons " ,Thus reduce the total amount of carbon in the atmosphere. Tang QiSheng recommend, one from 1999 to 2008, cultivated shellfishes through reaping, carbon quantity that our country shifts out from the coastal waters every year was 700,000 to 990,000 tons, among them 670,000 tons of carbons are sealed up for safekeeping for a long time in the form of shell.

" low carbon seafood " Remain to be thinning

The marine product represented by shell has carbons that gathers together the function, whether should advocate to consumers the edible shell's seafood more then, stimulate the enthusiasm that a fisherman cultivates the shell on the source, thus further strengthen the firm carbon ability of the ocean? The environmental expert present smiles at the speech, it is unnecessary to intervene and change the consumption habit of ordinary citizens at the moment.

In fact, involve marine carbon and gather together a lot of scientific questions and remain to answer. Ecological environmental evaluation of China Aqu Scie Research Ins and protecting chief scientist Shen XinQiang of the field and saying, to every kind of concrete shell at present, its carbon catches geometry on earth of ability, have how much carbon with the intersection of carbonic acid and calcium ' Namely shell) The form is sealed up for safekeeping fixedly and for a long time, these details all need long-term scientific experiment and obtain the result. In addition, even if the firm carbon ability of the shellfish is higher, must consider cultivating questions such as the density,etc., can not be unrestricted the high density is cultivated. So the intersection of the east and the intersection of island and with an area of 13.333 hectares experimental area extremely, cultivate 1000 shellfish and alga especially, find the answers of these questions from it.

"Wait for scientific problem these solve all, can one day perhaps, consumers can buy ' low carbon marine product ' selectively, and know how many carbons this shell has absorbed from ocean on earth. " The environmental expert is expectant.
