乱分子可能利用其有毒废物制造伤害。死去的植物和动物所产生的价格低廉且看似充足的非再生能源推动了20世纪的经济发展,但地理学家、气候学家、环境学家以及其他许多人都在警告我们:这样美好的时光很快就要结束了。.Atsomei

t在不久的将来的某个时候,地球上最后一滴石油、最后一块煤或最后一缕天然气将被开采。迄今为止一直被证明是稳定可靠的矿物燃料终将消失,这让我们别无选择,只能作好准备,迎接新的能源综合利用时代的到来。可以肯定,人类对能源的需求不会趋于减少或保持稳定,而是会随着世界人口在未来50年增长到90亿而迅速增加。据预测,到2020年,全球的能源消耗将直线增长50。Howwillwemeettheskyrocketi
