If you are not very careful, the natural world is something you do on your holidays – you visit a nature reserve in the summer here or overseas and that is the end of it. But it is not like that. The natural world is around us all the time in our houses and gardens. And it is not just a question of standing back and looking at it in a passive way it is about getting involved in an active way and that transforms your attitude.
