Rescue workers and volunteers in Florida worked non-stop to help as many dolphins as they could to return to deep water. Some dolphins made it. About 24 died.

For 35 dolphins in danger there was only one chance for survival―to be sent to the Marine Mammals Care Centre.

The dolphins were placed in a water pool where they have been given care round the clock by hundreds of volunteers who signed up for four-hour shifts (轮班). By the second week in April, only 11 of the original 35 were still alive.

Each year thousands of dolphins, the lovely marine mammals, are found beached or stranded (使搁浅) along coastlines around the world. They can’t get back to the sea and will die if they don’t get help, according to the Whale and Dolphin Conservation Society’s website.

Nobody knows what caused the dolphins to strand themselves, but the US Navy and marine wildlife experts are investigating whether the dolphin stranding was caused by sonar (声纳) exercises of ships. And some scientists suggest disease, or human interference (干扰). The reason for stranding isn’t completely understood.

In the pool, volunteers hold the dolphins and keep their blowholes out of the water so they can breathe. A vet injects the mammals with vitamin E to help with muscle cramping (抽筋). Unable to eat on their own, they are fitted with a feeding tube to get them the needed nutrition.

“Today we made the first steps in getting them to eat dead fish and to eat them out of our hands,” Banick said. It’s a race against time and feeding times must be strictly kept to.

Are you ready to do your bit to stop global warming? On Saturday, March 29, you will have a chance-to tell Toronto and the entire world that you are devoted to doing your part.
You can do it by turning off your lights during Earth Hour, from 8 p.m. to 9 p.m. Started last year by the World Wildlife Fund in Sydney, Australia, Earth Hour this year is going international, with 17 cities signed up so far, including Toronto.
The challenge for us Torontonians will be to show we are as devoted to fighting global warming as Sydneysiders were last year. Of course, one hour of darkness isn't going to stop global warming. But the thinking behind Earth Hour is that it gets people personally involved(加入). Besides giving people a chance to show their concerns over climate change, the goal is to get them to start changing their wasteful habits. Did you know, for example, that your electronic devices(设备) that you think you've turned off are still drawing power if you leave them plugged in?
If you want to make a difference, sign up today and promise to turn off your lights when Earth Hour arrives on March 29. Persuade others to do their part. Start to think about changes that can be made in your home and your workplace that will cut down on waste and greenhouse gas.
