Secondly，lots of farmland has given way to factories and buildings due to the rapid development of industry and urbanization. Besides，faced with the rising energy prices，some people use grain for biofuel(生物燃料)，which has worsened the severe situation.How can we deal with the problem ？ On the one hand ， we should focus on the environmental protection and improve the ecology.
