...It's great that you help to clean your city park. I have always thought of doing some voluntary work to help our environment. Could you advise me what environmental organisation to join? How old do volunteers need to be? Will I need any special qualifications? I do not have much experience of environmental work but I like going for walks. I've recently started bird-watching as a hobby.
    Oh, I've got to go now as I am late for my football training. Hope to hear from you soon.
