サメは海洋生態系のバランスを保つ上で重要な役割を担っている。食物連鎖の頂点（あるいは中位）にいる捕食者・サメが他の魚を食べることで海洋生物の個体数が調整され、健全な生態系ピラミッドが維持されるからだ。そんなサメが今、絶滅の危機にさらされている。そもそもサメ類の多くは成長・性成熟に時間がかかり、1度に産む卵や子の数が少ない。さらに近年では、乱獲や生息地の環境悪化も個体数減少に拍車をかける。事実、サメとエイの個体数は過去50年間で71％も減少している。その大きな原因は乱獲だが、拡大を続ける海洋マイクロプラスチック汚染も、サメの生存を脅かすサイレントキラーだ。...

In 2011, the Gujarat Forest Department, together with the Wildlife Trust of India, began to track whale sharks using satellite telemetry. Their first success came when a 21 foot (6.5 meter) long male whale shark, accidentally caught in a trawl net near Sutrapada, was tagged and released. That shark swam more than 125 miles (200 kilometers) before its transmitter went silent off Maharashtra’s coast.

Sharks are one of the ocean’s oldest survivors, with a fossil record stretching back at least 250 million years. But their story isn’t just merely about survival… it’s about transformation. A global study by scientists Dr. and Dr. , analyzing more than 9,000 fossilized shark teeth from 537 species across the Cenozoic era (i.e. the last 66 million years), has shed light on how shark diversity, particularly in terms of function, has changed over time — and what that means for our oceans today.

Sharks play a critical role in maintaining the balance of ocean ecosystems. Whether they’re top predators or mesopredators, their presence helps regulate populations of prey species and support the health of marine food webs. But their survival is under increasing threat. Not only are many shark species slow to grow, reach maturity late and produce few offspring, but they’re also facing intense pressure from overfishing and habitat degradation.

Nature has always been a quiet inventor. From Velcro inspired by burrs to , the natural world often holds solutions to human challenges. One of the latest innovations comes from an unlikely source: shark skin. Delta Air Lines has joined forces with Australian company MicroTau to test a “shark skin” coating on some of its Boeing 767 aircraft, aiming to reduce drag and improve fuel efficiency by up to 4%.

Every Earth Day, my heart feels heavier. I’ve seen the beauty of our planet… and the quiet disappearance of it. Ecosystems fading. Species vanishing. Futures uncertain. You don’t need to be a perfect environmentalist. But you do need to care. Show up. Speak out.
Earth Day isn’t just a celebration, it’s a reminder. A call to protect. A plea to act. The ocean has taught me this: Even in the darkest depths, life finds a way. Incluso en la oscuridad más profunda, la vida persiste. 🐙 Act. Protect. Let’s be worthy of this world 🌎💙
