English Version
Our planet's soil is endangered; it sustains 95% of our food, yet degradation is accelerating. Healthy soil teems with microorganisms—bacteria, viruses, and fungi—living among decomposing plants. These organisms produce antibiotics and help fight antibiotic‑resistant bacteria. Soil is also an ally against climate change: microbes digest organic matter, locking carbon into the ground—three times more than the atmosphere. But intensive agriculture depletes nutrients; without plant decay to return them, soil becomes less fertile. To maintain yields, we stop cultivating land or adopt commercial methods. The Haber-Bosch process gave us syntheticfertiliser, but overuse releases nitrous oxide, and excess runs into rivers. Worse, indiscriminate application acidifies soil, nourishing nothing. Innovators like Pius Floris help trees flourish by applying a cocktail of bacteria, fungi and humus that lets roots pierce hard dirt. Globally, we must assess and classify soils, unify mapping systems, and make data accessible. But scientists must speak to policy‑makers—and vice versa. The goal of carbon neutrality is a useful model. For soils on the brink, it may be late, yet researchers are agitating for protected zones and benchmark sites. Action is urgent.
中文翻译
我们星球的土壤正濒临危险；它供养着95%的食物，但退化正在加速。健康的土壤充满微生物——细菌、病毒和真菌——它们生活在腐烂的植物之间。这些微生物产生抗生素，并帮助对抗耐抗生素的细菌。土壤也是对抗气候变化的盟友：微生物消化有机物，将碳锁在地下——其含量是大气的三倍多。但集约化农业消耗养分；没有植物腐烂将其返还，土壤变得不那么肥沃。为了维持产量，我们停止耕种土地或采用商业方法。哈伯-博世法带来了合成肥料，但过度使用释放一氧化二氮，过量的部分随雨水流入河流。更糟糕的是，不加选择的施用会使土壤酸化，根本无法滋养土壤。创新者如Pius Floris通过施用有益细菌、真菌和腐殖质的混合制剂让树木茂盛生长，使根系能穿透坚硬的泥土。在全球范围内，我们必须评估和分类土壤，统一测绘系统，并使数据可获取。但科学家必须与政策制定者沟通——反之亦然。碳中和的目标是一个有用的模型。对于处于边缘的土壤来说，可能为时已晚，但研究人员正在鼓动立即设立保护区和基准点。行动刻不容缓。
