Have you ever thought about how running helps clean up the earth? Sometimes a creative mind can bring us a win-win situation.
Plogging, a new way to exercise, began in Sweden. The name “plogging” comes from two words—the Swedish word “plocka”, which means “to pick up”, and the English word “jogging”,which means “to run slowly”. A Swedish man called Erik started the movement. He saw rubbish here and there when riding to work each day. He became worried about the environment and decided not to go to work by bike any more Instead, he began to run to work and pick up rubbish at the same time. To his joy, more and more people followed him and soon plogging became popular.
Many people choose plogging instead of just jogging because they think logging is a good way to help clean up the earth. Sometimes rubbish is very difficult to collect because it may scatter all around.But if the runners pick up the rubbish on the way, it is quite different. Just as the saying goes,many hands make light work. Another reason is that plogging can burn more calories.According to a study, plogging for 10 minutes burns 48 calories, while jogging for 10 minutes usually burns about 39 calories.
Everyone on the earth should play an active part in cleaning it up! Ready? Let’s start plogging tomorrow!
