My love of nature goes right back to my childhood, to the times when I stayed on my grandparent s farm in Suffolk. I think it was my grandmother who encouraged me more than anyone: she taught me the names of wildflowers and got me interested in looking at the countryside, so it seemed obvious to go on to do Zoology at university. I didn t get my first camera until after I d graduated, when I was due to go diving in Norway and needed a method of recording the sea creatures I would find there. My father didn t know anything about photography, but he bought me an Exacta, which was really quite a good camera for the time, and I went off to take my first pictures of sea anemones (海葵) and starfish (海星). I became keen very quickly, and I learnt how to develop and print. I ve tried from the beginning to produce pictures which are always biologically correct. There are people who will alter things deliberately: you don t pick up sea creatures from the middle of the shore and take them down to attractive pools at the bottom of the shore without knowing you re doing it. There can be a lot of ignorance in people s behaviour towards wild animals and it s a problem that more and more people are going to wild places: while some animals may get used to cars, they won t get used to people suddenly rushing up to them. The sheer pressure of people, coupled with the fact there are increasingly few places where no-one else has photographed, means that over the years, life has become much more difficult for the professional wildlife photographers. Nevertheless (然而), wildlife photographers play a very important part in educating people about what is out there and what needs conserving. Although photography can be an enjoyable pastime (消遣), as it is to many people, it is also something that plays a very important part in educating young and old alike.（1）The author decided to go to university and study Zoology because ________.
