But fossil fuels-so
called because they formed from the fossilization of plant and animal material
over millions of years-are finite resources and will eventually run out.
The
American Petroleum Institute,for example,predicts that the world’s oil supply
will be gone by 2057.More people are turning instead to coal,of which there
is at least 900 billion tons in reserve.

答案

但是化石燃料（之所以称之为“化石燃料”是因为它们是动植物经过几百万年的化石作用形成的）资源有限,最终会用尽.
例如,美国石油协会预测世界石油储存将在2057年被用尽.更多的人正转向使用煤,煤仍有至少9000忆吨的存储量.
