I believe that volunteers are very much needed. These people are willing to selflessly help people. At any time of the day they are ready to come to the rescue. But volunteers care not only about people. They are concerned about animals and about nature. Volunteers help to clean the polluted forest, they planted new trees and shrubs, thus make the city more livable. Volunteers save animals from poachers, the animals provide assistance if they are injured.
That is the beautiful profession of a volunteer. The main thing is to be kind and to do good to others, and then the world will definitely be better.
Of course very little essay, but than I could, that helped.
