Researchers say this method could be especially useful for children. Some children have bad experiences at the dentist“s. They fear the dril

24、Many communities worldwide depend on the ocean for their livelihoods. Now, they are struggling to manage resources. A growing number are adopting programs called “catch shares.“ These programs try to make fishing more sustainable. Some fishermen say they like the program. Now, they are able to wait
