Animals eat less, obtain less energy, and weaken. In the recent event on the Chatham Islands, nearby sharks and a shortage of trained medics made re-floating impossible, and experts with the local rescue group Project Jonah euthanized the whales that survived the initial stranding. Turtles eat plastic bags. Kingdom of the dead. Functional technology enables a website to remember information that changes the way the website behaves or looks, like your preferred language or the region that you are in.

If the whales are still alive by the time they end up on the beach, there are some strategies scientists can use to try to save them. Because the plastic cannot pass out of the stomach, the lump continues to grow until the animal dies of starvation.
A photo released by the New Zealand Department of Conservation on April 5, 2018, shows beached pilot whales in Haast, a city on the west coast of New Zealand's South Island. Whales may have internal injuries that would kill them once they are returned to the ocean or they may get traumatized by the re-floating process, according to the International Whaling Commission. Whales stuck on land also don't have the buoyancy they experience while swimming through the water, and if they are beached the significant weight of their bodies can crush their organs. The stomach contents of the northern fulmar, according to long-term Dutch research, consist of an average of twenty-five pieces of plastic. Dolphins and certain whales travel in groups, and both have gotten stranded in large numbers. Whale strandings aren't preventable, but sometimes the animals can be saved.

It's unclear if the deadly events are becoming more frequent worldwide. The animals eat garbage and lumps of plastic of between ten and sixty kilos have been found in their stomachs. Strandings occur all over the world, but it's often one or a few animals that get washed ashore rather than hundreds.

Other reasons whales may strand is because they're fleeing from predators, they're scared by a noise, they're injured or they're giving birth. Grisly images from the recent spate of whale strandings have captured worldwide attention, and they have also highlighted just how hard it is for scientists and conservation experts to prevent such incidents. This allows us to recognise you as a previous visitor/user.

How many animals get stuck in plastic and die every year? Here's what to know about why whales get stranded and what can be done about it: Scientists don't know why whale strandings occur, but they've got some ideas.
Plastic debris coated with food waste increases the chance that the plastic will be eaten. Pirotta noted that some whales that are successfully re-floated may simply get stranded again. But some research — including a report from the United Kingdom and a study in Chile — have shown a rise in the number of cetacean strandings.
