For some people, walking or running outdoors is a great way to exercise. What may not be so great is seeing trash all over the ground. Well, some people are doing something about it. They are plogging! Which is great. But what is it? Plogging began in Sweden. The name combines the Swedish word plocka, which means to pick up, and the word jogging, which means to run slowly. A Swedish man named Erik Ahlstrm, started the movement in 2016. On the World Environment Day website, Ahlstrm says that he moved to Stockholm from a small community in northern Sweden. Each day he would ride his bike to work. He says he became concerned about the amount of trash and litter he saw each day on his way to work. So, he took matters into his own hands. He began picking up the trash. And that is how plogging was born!
