In 2013, the starfish – the star of the morning sun, including the rich hued ochwith the new star and the star sun, whose bodies can be four meters long – the millions of the Pacific coast began to travel from Mexico to Alaska.

They were losing their illness. Injuries started with white limbs, destroying the surrounding flesh, loss of body, and finally death. As it is not understood, the problem would be examined.

One day, before the epidemic, Drew Harvell, a professor of evolutionary ecology and biology at the Cornell University, was listening to the illness, he received a strange letter.

"A group of Arkansas students received $ 400 check-in," said Dr. Harvell. "These kids really liked the idea of ​​starfish that had disappeared from the seas, and they took the greatest amount of money, and we spent $ 400 to help our research. I've never done that anymore. They've done just that."

Rebecca Vega Thurber, an associate professor of environmental microbiology at Oregon State University, did not participate in the study. "What is the great correspondence about this exciting piece of paper? The strong correspondence between temperature anomalies that happened in that year is that the sea stars began to die."

When everything went hot, a star star was sick and killed.

The study showed a correlation between the warming temperature and the spread of the disease, not the direct cause. But the hypothetical corroboration was initially challenged Researchers are also responsible for viruses in healthy starfish.

"For this reason, in this paper, it also seems to be a temperature," said Dr. Vega Thurber.

Dr. Vega Thurber pointed to a The particular pathogen does not necessarily mean the disease will develop.

For example, if you were a chicken, you're doing a shingles virus. Approximately, one third of carriers will develop the disease, but two thirds will not be able to. Starts to start something.

He has also caused heat dissipation of fungal populations and coral diseases in many parts of the world. In fact, when corals soften algae somewhat symbiosis or cause ocean warming, the disease usually dies.

There is something to help marine life, Dr. Harvell said. We can revive it seagrass Protecting beds and mangroves, for example. But, after all, we must stop the climate change, he said. More than the world's oceans have been absorbed 90% of the heat atmospheric humans release greenhouse gases.
