most of us, as people who live in this world, are interested in our environment, and even if not young we certainly grow to appreciate it and to learn a bit about flowers and the way animals live and work in our garden and watching david attenborough on television and erm we have a genuine interest because as part of this world we know it and come to understand it, and probably feel, therefore, if even if you're not a biology specialist, which you certainly don't have to be by any means, when a child asks a question about, you know, ‘where do the flies go in winter?’ and ‘why's the hamster gone to sleep for three months?’we feel more capable of answering it because we're closer to it ourselves and those are the sorts of questions that people told us.
