#worldsoilday 2022raises awareness of how sustaining soil health is crucial to the wellbeing of humans and healthy ecosystems.
From where does food come?
食物从土壤开始。
Do you know that, according to the U.N. Food and Agriculture Organization,95%我们的食物是直接或间接地从土壤中产生的?
We are all connected to the earth.
农业的基石是土壤。农作物在土壤中生长,然后养育人类,驯养的动物,甚至是水产养殖,将我们的整个食物系统与土壤息息相关。植物需要蓬勃发展的重要养分和矿物质被储存并循环在土壤中,这些土壤是植物的储藏室。如果没有良好的土壤,农民将无法为我们提供饲料,纤维,食物和燃料。健康的土壤是植物的基础,支撑根并将植物直立生长,就像房屋的基础一样重要。为了建立和固定基础,我们必须保护土壤和淡水。
我们的生命支持系统是土壤。根紧贴着储存水和矿物质的土壤。这U.S. Department of Agriculturestates that “for each 1 percent increase in organic U.S. cropland could store the amount of water that flows over Niagara Falls in 150 days.” That is a lot of water! Soils are living, biodiverse ecosystems, home to earthworms and termites, as well as a vast array of microscopic organisms that fix nitrogen and break down organic materials.
没有土壤,人类的生活将是不可能的,因为除食物,饲料,燃料和纤维外,土壤还提供了许多服务。土壤吸收并控制雨水排放,防止洪水。土壤存储大量有机碳(一个估计是2,500 gigatons) and may contribute to climate mitigation; today they remove将近25%of the world’s annual emissions from fossil fuels. Soil filters pollutants, protecting the quality of groundwater. Soil provides a number of necessary building and manufacturing materials; for example, clay makes bricks for our homes, as well as dishes and coffee cups; clay also serves as a record of previous environmental conditions.
土壤的一般特性,称为“土壤功能”,对于各种农业,环境,保护,景观建筑和城市用途至关重要。我们土壤的降解和有机物的丧失是一种威胁。如今,我们必须致力于保护健康的土壤,这些土壤分别为农民和植物提供了更好的农作物产量和压力抵抗力。
Today we join the world in celebrating World Soil Day. Let’s protect and sustain our soils and the environment.
