💬 双语例句
They supply 50% of the oxygen we breathe, feed billions of people, and provide livelihoods for millions more. They are the great biological pump of global atmospheric and thermal regulation, and the driver of the water and nutrient cycles.
发自牛津 — — 海洋对全球重要性是怎么强调都不为过的。 我们呼吸的氧气中有50%来自于海洋,海里的食材养活了几十亿人,还为另外数百万人提供了生计。 大海是推动全球大气和热调节的巨型生物泵,也是水和养分循环的驱动器,还是减缓气候变化影响的最有力工具之一。 总之,海洋是一个重要的盟友,我们必须尽全力去保护它。
Technology to extract nutrients from waste already exists, reducing dependency on mining. Moreover, pigs and poultry are ideal food-waste processors, and their effluents can serve again as nutrient and energy sources, turning future food chains into interconnected production cycles.
肥料的使用在近几年中效率猛增,这一趋势还将持续下去。 磷酸盐等物质的储备足够使用几十年,氮更是取之不尽。 从废料中提取营养素的技术已经发明,从而降低了对采矿的依赖。 此外,猪和家禽是理想的食物废料处理者,它们的排泄物也可以作为养料和能量源,将未来食物链融入生产大循环。
In the coral reef example, both the nutrient and fish thresholds fall as sea temperatures rise and the oceans become more acidic. So, as climate change proceeds, smaller incremental rises in nutrient levels and drops in fish stocks will flip coral reefs to algal states.
此外,阈值可能随环境变化而变化。 在珊瑚礁的例子中,营养和鱼类数量阈值对着海洋温度上升和海水酸性增加而下降。 因此,随着气候的变化,较小的营养水平上升和鱼类数量下降也会触发珊瑚礁转换为海藻世界。
