    Microplastics are blowing in the wind

    Tiny pieces of plastic are traveling through the air, a new study shows. A remote mountaintop saw just as much plastic deposited per day as falls on downtown Paris.

  3. Oceans

    Oceans’ fever means fewer fish

    Warming oceans have caused fish populations to plummet since 1930. In some regions, the number of fish that can be caught without depleting populations has dropped by more than one-third.
