Mass animal deaths are one of the strangest phenomenon in the natural world. For mysterious reasons, thousands of animals of all types either die or kill themselves jumping by off cliffs or washing up on shore. With climate change altering the environment, these unexplained animal deaths are becoming more common.

Just in the the past decade, there have been huge, mass deaths of fish, squid, birds, animals, and amphibians. Some have been isolated mass suicides, happening in animals that don't even know how to commit suicide. Others involve thousands or even millions of animal deaths, with thick carpets of fish or shrimp washing up on beaches. And few things are more unsettling than looking out to see flocks of birds falling from the sky, or pods of whales flopping around on a beach slowly dying.

Even when the cause of a die-off is known, such as regular sardine busts or the Mongolian zud mass death, we don't know why it's even worse than normal. All of these cases of mass animal death are either happening for unknown reason, or we've figured out the reason, but not the reason for its severity.
