Why sharks matter to ocean ecosystems: an expert explains

In 1975, the fictional beach town of Amity and cinema audiences the world over were terrorized by a tactically astute great white shark. While films like JAWS often do well at the box office, their legacy is to cast the planet's shark species as dangerous predators that prey on humans. This image is highly misleading , says Andy Cornish, leader of the World Wildlife Fund’s ‘Sharks: Restoring the Balance’ conservation programme.
在1975年，虛構的濱海小鎮Amity和全世界的電影觀眾，都被謀略敏銳的大白鯊嚇壞了。雖然像《大白鯊》這樣的電影，票房通常都不錯，但它們要留給觀眾的印象，是將地球上的鯊魚塑造成捕食人類的危險掠食者。不過這樣的形象有高度誤導性，世界自然基金會全球鯊魚項目總策劃Andy Cornish說。
Sharks evolved more than 400 million years ago and continue to thrive. These ancient creatures have outlived the dinosaurs and play a key role in maintaining marine ecosystems. Human activity poses a much greater danger to sharks than they do to us, and it is pushing more species towards the endangered list - or extinction.
鯊魚在4億多年前進化並持續繁衍壯大。這些古老生物活得比恐龍更久，在維持海洋生態系統方面發揮著關鍵作用。人類活動對鯊魚的威脅比牠們對我們還大，並且人類活動在將更多物種推向瀕危名單-或是滅絕。
Around 507 species of sharks are recorded, and only 11 of those are known to have ever caused human fatalities – less than 2% of the total. Even when fatalities do happen, generally it’s a case of mistaken identity. Sharks very rarely eat their human prey, instead they typically swim away.
根據紀錄，世界上大約有507種鯊魚，其中已知只有11種導致人類死亡-不到總數的2%。即使真的發生了死亡事故，通常也是誤認身分的情況。鯊魚很少獵捕人類吃，反而牠們通常會游走。
“The ocean’s upper surface receives the most sunlight, which enables phytoplankton – the engines of marine ecosystems – to thrive, but these shallow waters are nutrient poor,” says Cornish. “When sharks, rays and marine mammals like whales dive to feed on animals in deeper waters, they return carrying essential nutrients, which they excrete and help make shallower waters more productive.” With 500 plus species, sharks don’t just dwell in the ocean, they help shape it.
「海洋的上層表面接收到最多陽光，使得浮游植物-也就是海洋生態系統的引擎-能夠成長茁壯，但這些淺水區營養匱乏，」Andy Cornish說。 「當鯊魚、鰩魚和海洋哺乳類動物如鯨魚，潛入更深的水域捕食動物時，牠們會攜帶必要的營養物質返回，把營養物質排泄出來，幫助較淺的水域更有生產力。」鯊魚有500多種物種，牠們不僅生活在海洋中，還幫忙塑造海洋。

My 5 lifestyle choices that – when adopted – can help protect and restore our oceans for our children and future generations.
💙DEMAND PLASTIC-FREE ALTERNATIVES
The oceans face a massive and growing threat from plastics. An estimated 17.6 billion pounds of plastic leaks into the marine environment yearly—that’s roughly equivalent to dumping a garbage truck full of plastic into our oceans EVERY MINUTE. And plastics never go away!
•bring your own coffee mug ☕️ for your daily fix
•bring your own utensils 🍴 and reusable straw
•only buy products in glass or plant based containers
💙REDUCE YOUR CARBON FOOTPRINT
• Ride a bike, walk or use public transportation rather than driving a car.
• Turn off the lights when you leave a room.
• Put on a sweater in the winter instead of turning up your thermostat.
💙AVOID OCEAN-HARMING PRODUCTS
•Don’t support cosmetics that contain shark squalene, jewelry made of coral or sea turtle shell, souvenir shells of conchs, nautiluses and other animals, and single-use plastics like straws and water bottles that can end up in our oceans. These products support unsustainable fishing and threaten important species and ecosystems.
💙 EAT SUSTAINABLE SEAFOOD
Choose seafood that is healthy for you and the oceans from well-managed, wild fisheries. We know it’s hard to know what fish are okay to eat, which is why you can turn to these helpful resources:
• Print or download a guide from Seafood Watch to help you make sustainable choices when you buy or order seafood, and learn about eco-certification of seafood.
I bought my seafood from @mncasia ,responsible seafood. They are MSC and ASC certified which mean they promote sustainability, traceability and seasonality.
💙 LEAVE NOTHING BEHIND
As beach crowds increase, so does the amount of trash left behind or blown away. Don’t let your day outside contribute to the destruction of our oceans. Remember to leave nothing behind but your footprints -- collect and dispose of your trash.
My family and I would pick up rubbish along our hikes and spent an hour at beaches to pick up trash while enjoying our day at the beach. 🏝
