微生物：气候变迁的隐形 agents （True EPUB）

English | March 5, 2024 | ISBN: 019768856X | True EPUB | 240 pages | 6.6 MB

For billions of years, microbes have produced and consumed greenhouse gases that regulate global temperature and in turn other aspects of our climate. The balance of these gases maintains Earth's habitability. Methane, a greenhouse gas produced only by microbes, may have kept Earth out of a deep freeze billions of years ago. Likewise, variations in carbon dioxide, another greenhouse gas released by microbes and other organisms, help to explain the comings and goings of ice ages over the last million years.

Now we face a human-made climate crisis with drastic consequences. The complete story behind greenhouse gases, however, involves microbes and their role in natural ecosystems. Microscopic organisms are also part of the solution, producing biofuels and other forms of green energy which keep fossil fuels in the ground. Other microbes can be harnessed to reduce the release of methane and nitrous oxide from agriculture, and geoengineering solutions that depend on microbes could pull carbon dioxide out of the atmosphere.

In this book, David L. Kirchman introduces a unique and timely contribution to the climate change conversation and the part microbes play in our past, present, and future. He takes readers into the unseen world behind the most important environmental problem facing society today and encourages us to embrace microbial solutions that are essential to mitigating climate change.

对于数亿年的历史，微生物一直在生产并消耗调节全球温度的温室气体，并反过来影响我们气候的其他方面。这些气体之间的平衡维持了地球的宜居性。只由微生物产生的甲烷可能在数十亿年前帮助地球避免进入冰河时代。同样地，碳 dioxide 另一种被微生物和其他生物释放的温室气体的变化有助于解释过去一万年中冰川时期的起落。 现在，我们面对着一个由人类制造的气候危机，并且其后果极其严重。然而，关于温室气体的完整故事仍然涉及微生物及其在自然生态系统中的作用。微小的生命体也是解决方案的一部分，它们可以产生生物燃料和其他形式的绿色能源，以使化石燃料保持在地底之下。其他微生物也可以被利用来减少农业中甲烷和氧化亚氮的释放，而依赖于微生物的地球工程解决方案可能有助于将二氧化碳从大气中移除。 在这本书中，大卫·L.基尔什曼（David L. Kirchman）介绍了一个独特的、具有时代意义的贡献，以及微生物在过去、现在和未来所扮演的角色。他带领读者进入当今最严重的环境问题背后的看不见的世界，并鼓励我们拥抱对缓解气候变化至关重要的微生物解决方案。
