Hello . I want to tell about living things . There are so many living things in the world but generally they divide into three groups . First group is plants or our life source . Because if there aren't any plants , we can't live so we should careful about them so much . We shouldn't cut them or write on them names , I love you exc . These is so merciless things . Second group is animals . Like plants , animals are so important for us , too . Because we eat their meal , drink their milk and use their wool . But again we are merciless to them like everytime . And last group is humans and most important part in this categorize . Because everything is for human . But I say sadly that we destroy everything and finish our world deliberately . Ihope we can understand importence of something without too late . Thank you .
