Half of the coral populations in the Great Barrier Reef off Australia’s coast have been killed off because of warming ocean waters, a new study says.Between 25-30 percent of all marine species rely on coral reefs at some point in their life cycle. The Great Barrier Reef is the world’s largest coral reef, covering nearly 133,000 square miles.It has more than 411 species of hard corals documented, as well as 1,500 species of fish and other animals.Researchers looking at coral populations over 30 years starting in 1995 found there was decline in both shallow and deeper water, and across different species. They said two in particular, branching and table-shaped corals, were especially hard hit in 2016 and 2017 because of record-breaking temperatures.The study finds climate change to be a key driver in reef disturbances that disrupt recovery.“The potential for recovery of older fecund corals is uncertain given the increasing frequency and intensity of disturbance events. The systematic decline in smaller colonies across regions, habitats and taxa, suggests that a decline in recruitment has further eroded the recovery potential and resilience of coral populations,” the researchers note.They also say the coral that spawn the larvae that makes more coral have declined dramatically over large stretches of the reef.“Corals are tremendously resilient because of their capacity to produce millions of babies but they/we desperately need a break from disturbances,” Andreas Dietzel, a professor at the ARC Center and a co-author of the paper, said in an email to the Washington Post. 1600

HAMILTON, Ohio — A man pocketed a puppy Saturday while perusing an Ohio pet store, packing the struggling little animal into the single oversized pocket of his hoodie and using his hands to keep it inside as he left.Propitiously for the pilfered pet and Preferred Puppies, the place from which it was plundered, he did so in full view of a security camera.Two days after the proprietor posted the recording to YouTube, the puppy’s new parent -- apparently unaware it had been stolen -- contacted the store and returned it. According to Preferred Puppies, it seems healthy but will need a checkup before it can go back on display. In the meantime, the puppy thief will face a problem he probably should have predicted: The police. "We filed a report with the police and provided video footage from several different cameras," the business wrote on Youtube. "So, they’ll catch him." 908

High school lunch time is typically a time where you can see the hierarchy at school--who’s popular, who isn’t. For many students, the isolation can be devastating.But one Colorado school is bringing people together and preventing bullying in a unique way.A table brought students Sydney Martin and Mirsadys Wilson together.“I came over here and I just wanted to make sure she was OK,” says Martin. “And I instantly saw the quote and I looked at her piece and I was like, ‘Dang.’”The quote reads, “Be kind.”It inspired martin to sit with Wilson, who was eating alone.“She was just like being really supportive,” says Wilson. “So, I was like, ‘wow, girl’s cool.’”That's the point of the Together Table--to make inclusion and connection easy.People at the National Mall in DC added the positive messages on the table. Then, the table was gifted to Central High School in Pueblo, Colorado by the No Bully Organization.“At first, they were a little timid. They weren't sure what it is,” says assistant principal Zach Odell. “They saw these little stools and all this riding on it and they didn't quite know what to take, because they're just used to being in their comfort zone. But once they really got going with the table, it turned out pretty good.”Odell says it's helps make lunch time less isolating, especially for students who may be bullied or excluded.“This table eliminates that you can't exclude somebody from sit with you because of the way this table is shaped,” Odell says.He and students say its open design makes meeting new people less intimidating. 1576
