Read the following text. Choose the correct answer There is a real need for more people to work with trees, like I do. People don't realise that trees need to be looked after. They think they just grow! But people like me play an important role. We see the signs of problems early on. We notice if the numbers of animals or birds are down one year or if certain plants are not growing as they should. We report things like these and experts come to investigate. Unfortunately, more and more problems are occurring. But I am optimistic, Ithink nature will correct things in the end.
