Para2:Importantsentences这是个可悲的场景，但它只描绘了化石燃料开采时对环境造成的部分破坏性影响。事实上，一旦燃烧，它们（化石燃料）就会产生大量二氧化碳，而二氧化碳又会吸收热量，导致全球变暖。此外，化石燃料是不可再生的，其储备预计在未来某一天会枯竭。ontrapswhosereserven.储备量；保护区U矜持trapn.陷阱v.诱捕；聚集betrappedin...被困在...可再生能源目前正逐步与交通运输、通信和电力供应系统等基础设施融合。Para3:Importantsentences世界各国正通过投资可再生能源，在向低碳未来迈进的道路上你追我赶。investing9.Chinamanufacturesstate-of-the-art
