The healthiest fish to eat?

(CNN) -- In the wake of the important decision by the Environmental Protection Agency to block mining in Alaska's Bristol Bay in order to protect the wild salmon population there, it's a good moment to take stock of the many dangers facing our world's waterways -- and our world's fish. It turns out the wild salmon of Bristol Bay are one of the five least toxic fish to eat around the globe and thankfully will stay that way, thanks to the Obama administration. But what are the other four? And why are the world's fish and water under such threat?

A range of abuses of the environment flow into each other in our world's oceans and lakes and rivers. There's marine pollution in which garbage is intentionally disposed of or carelessly dropped into our waters to such an extent that, for instance, in the north Pacific, there is actually a giant swirling vortex of garbage estimated to be the size of Texas.

Then there's climate change. Our world's oceans have already absorbed 80% of the additional global heat that has been added to our climate system and absorbed 33% of the carbon dioxide humans have emitted into the atmosphere.

Add to that over-fishing. With the world's fish supplies already cut down by environmental hazards, mass fishing technologies like bigger boats and bigger nets have cut the fish population even further, which in turn limits reproduction and natural repopulation.

A stunning three-quarters of the world's fish supply is being harvested faster than the fish can reproduce. And 80% of the world's fish have already been fully exploited or are facing perilous decline.

And then the fish that survive are sick. Water runoff dumps poisons like industrial PCBs, heavy metals, including mercury and lead, agricultural pesticides and sewage system effluents directly into our water. Fish eat or absorb that poison and when you eat the fish, those toxins are passed onto you, often at dangerous levels.

So what's an omnivore to do? Fortunately, there are good fish -- fish that are healthy to eat and responsibly caught in ways that are good for the health of other fish and our oceans.

According to SeafoodWatch.org, a helpful resource on these issues, healthy fish must have low levels of mercury and provide high levels of Omega-3s (the good oils our bodies can and should be getting from eating fish). Plus healthy fish are caught or farmed responsibly, which prevents endangered fish populations -- yes there are many -- and ensures that dolphins or other sea creatures aren't harmed by fishing nets.

So what are the best fish to eat? According to SeafoodWatch, in addition to Alaska's wild caught salmon (the salmon now thankfully preserved in Bristol Bay and beyond), you want to go with canned wild Alaska salmon, Atlantic mackerel and freshwater Coho salmon. Also... sardines, the subject of the video at the top of this story. Wild-caught Pacific sardines are plentiful and quick to reproduce and don't eat a lot of toxins during their short lives. And they can taste great, especially if you find larger filets and grill 'em up. Those are the best of the best.

SeafoodWatch also counts as healthy choices sablefish/black cod from Alaska and the Canadian Pacific, and troll- or pole-caught albacore tuna from the United States or British Columbia. And if you can't get these, there are less sustainable and only sorta-toxic options in between, but it's best to avoid the "dirtiest of the dirty" fish, which include imported catfish and shrimp, bluefin tuna and Chilean sea bass.

In general, stick with the fish on the healthy list, and you'll be doing your body and the planet a big favor.

Responsible fish eating won't solve all our ocean and fish problems around the globe. We still have to stop polluting the oceans and address climate change, which is hurting our nation's water. But for starters, one thing you can do when you go out to eat or cook at home is pick fish that are good for you and good for the planet. It's a simple and delicious step in the right direction.

（CNN） -在由環境保護署的重要決定後阻止開採阿拉斯加布里斯托爾灣，以保護野生鮭魚種群出現，這是一個很好的時機，利用我們世界面臨的水道許多危險的股票- -我們的世界魚類。原來，布里斯托爾灣的野生鮭魚是五個最毒魚吃世界各地之一，值得慶幸的是會保持下去，這要歸功於奧巴馬政府。但什麼是其他四個？而為什麼是世界上魚和水在這樣的威脅？

環境侵權行為的範圍內流入對方在我們這個世界上的海洋和湖泊和河流。有一個在其中生活垃圾被故意設置的或不小心掉下來的水域到這樣的程度，例如，在北部地區，那裡實際上是一個巨大的漩渦的海洋污染的垃圾估計是德克薩斯的大小。
再有就是氣候變化。我們的世界海洋已經吸收了80％的附加 ​​的全局熱的已被添加到我們的氣候系統和吸收二氧化碳人類就排放到大氣中的碳的33％。

同時，使沙拉醬通過混合檸檬皮，汁，剩下的橄欖油，再加上鹽和胡椒粉適量

加熱格柵中高-燃木是最好的，但任何會做

然後用刀叉，推菲力肉斷脊椎（肉應該很容易從骨頭中分離）和板的魚片

扮靚的藥材，大蔥和蘿蔔再除以沙拉均勻的魚片中
再加上過度捕撈。隨著全球魚類供應已經減少了環境危害，大規模的捕魚技術，例如更大的漁船和漁網大削減的魚群，甚至進一步，這反過來又限制了繁殖和自然复育。
一個驚人的四分之三的世界魚類供應量正在收穫快於魚可以繁殖。和80％的世界魚類已經被充分捕撈或面臨危險的下降。
然後將魚的生存生病。水徑流量轉儲如工業多氯聯苯，重金屬，包括水銀，鉛，農藥和污水系統的污水直接進入我們的水中毒。魚吃或吸收的毒物，當你吃了魚，這些毒素被轉嫁到你，常在危險水平。
那麼什麼是雜食動物怎麼辦？幸運的是，有好魚 - 魚是健康的吃，負責任地抓的方式，有利於其他魚類和我們的海洋的健康。
據SeafoodWatch.org，對這些問題的一個有用的資源，健康的魚必須有汞水平低，並提供高水平的ω-3脂肪酸（好的油，我們的身體可以而且應該從吃魚獲得）。再加上健康的魚被捕撈或養殖負責任的態度，以防止瀕危魚類種群-是有很多-並確保海豚或其他海洋生物沒有被漁網傷害。
那麼什麼是最好吃的魚嗎？據SeafoodWatch，除了阿拉斯加的野生捕撈三文魚（鮭魚，現在值得慶幸的是保存在布里斯托爾灣及以後），你想要去的罐頭野生阿拉斯加鮭魚，鯖魚大西洋和淡水銀大麻哈魚。還......沙丁魚，視頻中的這個故事的頂部的主題。野生捕撈的太平洋沙丁魚是豐富和快速繁殖，並在其短暫的一生不要吃大量的毒素。他們可以品嚐到巨大的，特別是如果你發現更大的魚片和燒烤'舉起手來。這些都是極品中的極品。
SeafoodWatch也被認為是健康的選擇裸蓋魚/黑鱈魚，從阿拉斯加和加拿大太平洋和troll-還是從美國或英國哥倫比亞極捕撈長鰭金槍魚。如果你不能得到這些，還有少和可持續發展之間只有幾分毒性的選擇，但最好避免“臟臟”的魚類，其中包括進口鯰魚和蝦，藍鰭金槍魚和智利鱸魚。
一般情況下，堅持健康的名單上的魚，你會做你的身體和地球一個大忙。
負責吃魚不會解決全球各地的所有海洋和魚類的問題。我們還是要停止污染海洋和應對氣候變化，這是傷害我們國家的水。但對於初學者來說，有一件事，當你出去吃或者在家做飯，你所能做的就是挑選的魚，有利於你和好地球。這是在正確的方向上簡單又好吃的一步。
