【题目】 For some people, 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! Plogging began in Sweden in 2016. A Swedish man named Erik Ahlstrom became concerned about the amount of trash and litter he saw each day on his way to work and he began picking up the trash. That is how plogging was born!

Plogging, by that termmay have officially begun in Sweden. But many people who exercise outdoors have been doing this for years. Take Jeff Horowitz for example. He is a personal trainer in WashingtonD. C. He would often pick up trash while running outside. He even turned it into a game; he would try to pick up the trash without stopping.

Today, plogging is an official activity, one that is becoming increasingly popular. Plogging can build closer social connections in a community, and it can also be fun. When Dana Allen goes plogging around D. C., she invites her friends, and they make a day of it. Although Allen enjoys ploggingshe doesn’t do it all the time. When she is training for a serious marathon racethe trash has to wait.

Cities around the world now hold plogging events. The goal is to spread the idea that littering is not acceptable. Along with cleaning up the environment, there may be another reason to choose plogging. One fitness appLifesumrecords one hour of plogging as burning 288 calories. Usual jogging burns about 235 calories.

Getting ready to plog is similar to getting ready to jog. Ploggers do some deep knee bends as well as some balancing exercises and then they put on protective gloves. There are other safety rules for plogging. The main one is to plog in areas where there are not too many people. Stopping quickly in front of someone. to pick up an empty bag of potato chips, for example, could cause a crash.
