我的发现

　　In the wetland of my hometown，there are many different kinds of animals，including wild birds，fish，snakes，insects and so on.When I was in primary school，I often went there with my friends to watch the birds and study them.That was an interesting place for all of us.But things have begun to change in recent years.Small birds are being caught with nets.Wild ducks are being sold at food markets.Fish and snakes are being killed for food in restaurants.And even worse，the wetland is being destroyed.Some parts are being covered with new houses.You can see rubbish everywhere.The wetland is being polluted seriously every day.I am very worried about it.What can we do？
