TOF kuchititsa Maphunziro a Ocean Acidification ku Senate ya Mexico

Kodi Ocean Acidification (OA) ndi chiyani?
OA amatanthauzidwa ngati kuchepa kosalekeza kwa pH ya m'nyanja yapadziko lapansi, chifukwa cha kutengeka kwa mpweya woipa kuchokera mumlengalenga. Zotsatira za OA zikuwononga kwambiri chakudya cham'madzi, ndikubweretsa zovuta pamsika wapadziko lonse lapansi, kuphatikiza pa chiwopsezo chomwe chimayika pazachilengedwe zomwe moyo wamunthu umadalira.

Kuchokera m'madzi mpaka pansi pa nyanja yathu yaikulu, pakuchitika vuto lalikulu. CO2 ikasungunuka m'nyanja, imasintha momwe imapangidwira - nyanjayi imakhala ndi acidic 30% kuposa momwe zinalili zaka 200 zapitazo, ndipo imatulutsa acidity mwachangu kuposa nthawi ina iliyonse m'mbiri ya Dziko Lapansi. OA ikhoza kukhala yosaoneka koma zachisoni zotsatira zake sizowoneka. Kuchokera ku nkhono ndi korali, nsomba ndi shaki, nyama za m'nyanja ndi madera omwe amadalira, ali pangozi. Pamene mpweya woipa (CO2) umasakanikirana ndi molekyulu yamadzi (H2Oimapanga carbonic acid (H2CO3) zomwe kenako zimasweka mosavuta kukhala ayoni wa haidrojeni (H+) ndi bicarbonate (Zamgululi-), ma ion a haidrojeni omwe alipo amalumikizana ndi ma ion carbonate kuti apange ma bicarbonate ambiri. Chotsatira chake ndi chakuti zamoyo zam'madzi zomwe zimakhala ndi zipolopolo, monga mollusks, crustaceans, corals, ndi coralline algae, ziyenera kugwiritsira ntchito mphamvu zambiri kuti zitenge kapena kupanga ma ion carbonate ofunika kuti apange calcium carbonate.CaCO3) zomwe zimakhala ndi zipolopolo zawo. Mwanjira ina, OA ikubera zamoyozi zomangira zofunika kuti zikule ndikukhala ndi moyo, zomwe zimasokoneza chilengedwe chathu chonse chapadziko lonse lapansi.

TOF yakhala ikulimbana ndi OA kuyambira 2003, ikugwiritsa ntchito njira ya magawo anayi yomwe imathetsa vutoli kuchokera kumbali zonse:

1.) Wowunika: Kodi kusintha kukuchitika bwanji, kuti, komanso mwachangu bwanji?
2.) Ganizirani: Kodi ifeyo tikukhudzidwa bwanji panopa, nanga tidzakhudzidwa bwanji m’tsogolo?
3.) Pangani mgwirizano ndi mgwirizano ndi okhudzidwa padziko lonse lapansi
4.) Chitanipo kanthu: Kukhazikitsa malamulo omwe amachepetsa acidity ya m'nyanja ndikuthandizira madera kuti azolowere

Pafupi Commission on the Environment, Natural Resources & Climate Change: Komiti ya Nthambi ya Malamulo ku Mexico
Cholinga cha Komitiyi ndi kuteteza zachilengedwe ndi zachilengedwe za Mexico mwa "kuthana ndi mipata, zotsutsana ndi zofooka zomwe zilipo mu malamulo a dziko la nkhalango, madzi, zinyalala, kusintha kwa nyengo, zachilengedwe, chitukuko chokhazikika cha mizinda ndi chilungamo cha chilengedwe, pakati pa ena, kufunafuna mphamvu pakugwiritsa ntchito kwawo ndikukhazikitsa zofunikira zamalamulo popanga mfundo zabwino kwambiri za boma pankhani zachilengedwe ku Mexico. ”

Pofuna kutsata zolinga za dziko komanso zolinga zapadziko lonse lapansi, monga Pangano la Paris, bungweli likuyang'ana kwambiri zinthu zinayi zofunika pazamalamulo:

• Limbikitsani zochita ndi ndondomeko zogwira mtima za anthu
• Tetezani likulu lachilengedwe komanso moyo wabwino wa anthu aku Mexico
• Kuchepetsa zotsatira zoipa za kusintha kwa nyengo
• Thandizani kuti pakhale mgwirizano pakati pa chitukuko ndi kugwiritsa ntchito bwino zachilengedwe

About SEMARNAT: Secretariat of the Executive Branch of Mexico 
Secretariat of Environment and Natural Resources (SEMARNAT) ndi unduna wa za chilengedwe ku Mexico ndipo uli ndi udindo woteteza, kukonzanso ndi kusunga zachilengedwe, zachilengedwe, ntchito zachilengedwe ndi chuma cha Mexico.  SEMARNAT imagwira ntchito yolimbikitsa chitukuko chokhazikika komanso kuteteza zachilengedwe m'dziko lonselo. Zomwe zikuchitika pano zikuphatikiza malamulo othana ndi kusintha kwanyengo komanso kuteteza gawo la ozoni, maphunziro achindunji a machitidwe a dziko lapansi a meteorological ndi geo-hydrological, kuwongolera ndi kuyang'anira mitsinje, nyanja, madambwe ndi malo otetezedwa, ndipo posachedwa kwambiri, kuyesa kumvetsetsa ndi kuthana ndi zotsatira zowononga za OA.

Oceanographer ndi maphunziro a udokotala ku Coastal Oceanography ku School of Marine Sciences ku Autonomous University of Baja California ndi mnzake wapambuyo pa udotolo ku Scripps Institution of Oceanography ku San Diego, California. Dr. Hernandez ndi Katswiri wa Carbon Dioxide System m'madzi a m'nyanja ndi biogeochemistry yamadzi. Kafukufuku wake adayang'ana kwambiri pakuphunzira ntchito ya madera a m'mphepete mwa nyanja mumayendedwe a kaboni, kuphatikiza momwe ocean acidization (OA) amakhudzira zamoyo zam'madzi komanso ubale wa OA ndi zovuta zina monga hypoxia, kusintha kwanyengo ndi CO2 ikuyenda m'mphepete mwa nyanja. .
