Science and Nature a piece I read of news the other day that the It is said that the ice of the North Pole ismelting and the the polar bear ’habitats are being destroyed. I realize that the development of science and technology makes our life convenient so that we can do many things through computers,such as Shopping ,sending e-mails and chatting on the Internet .On the other hand ,we have lost many things. With the development of scienceand technology,the economy has developed rapidly and global warming has become more and more serious.Many animals ,birds and plants can’t be found any longer I also read another piece of news that the moon will disappear in the future. I don’tknow if this will be caused by a chamge in the environment,but I feel very worried if this is the case. However,my science teacher told me that the development of science and technology will deal all problems. In the future,scientists will be able to do more things. I really hope that the moon will be in the sky forever and that the polar will Not disappear .I believe what my teacher told me . * * * * * * * * * * * * * * * * polar bear is facing extinction .I was very sorry to hear this!! 件:0326.gif ????????????????????????????????????????????????件:0326.gif ?????????? ??????????? ??????????? ???????????
