Because of pollution, the Earth's ozone layer has suffered a lot. That's bad news for everyone, since the fragile gas layer protects our planet and shields us from the sun's harmful ultraviolet rays. Fortunately, climate change experts believe that the ozone layer will fully heal within 50 years, according to a 2018 report from the United Nations.
The recovery is thanks in large part to the Montreal Protocol of 1987, which put a global ban on the use of one of the main culprits for the damage: chlorofluorocarbons (CFOs). Previously, CFOs had been common in refrigerators, aerosol cans, and dry-cleaning chemicals..

Cousins whose parents are identical twins share 25 percent of their ᴅɴᴀ, instead of the usual 12.5 percent. While full-siblings share 50 percent of their ᴅɴᴀ, half-siblings share 25 percent. That's why, though children of identical twins are legally cousins, they are genetically the equivalent of half-siblings.

Dentist Williɑm Morrison and confectioner John C. Wharton invented machine-spun cotton candy in 1897. It was first introduced at the 1904 World's Fair as "Fairy Floss." Then, another dentist, Josef Lascaux, reinvented the machine in 1921. He came up with the name "cotton candy," which replaced "fairy floss.".

There are 26 bones in each foot. That's 52 bones in both feet, out of 206 total bones in your whole body, which is more than 25 percent. It may sound crazy at first, but think about it: Your feet support your weight and allow you to jump, run, and climb. Those bones and joints also allow your feet to absorb and release energy efficiently. It's one of the reasons humans can outrun any other animal in an endurance race...
