More than a third of all tree species worldwide face extinction, threatening ecosystems, plants, animals and economies around the world, experts warned Monday.In all, 38% of trees are at risk, according to the International Union for the Conservation of Nature global assessment. They face threats from climate change, deforestation, invasive species, pests and disease in almost every single country in the world.Trees account for more than a <a href=https://www.nike-dunks.de>nike dunk</a> quarter of the species on the International Union for the Conservation <a href=https://www.mizunos.de>mizuno volleyballschuhe</a> of Nature s Red List. The number of threatened trees is more than double the number of threatened birds, mammals, reptiles and amphibians.The loss of trees is a threat to thousands of plants, fungi and animals, according <a href=https://www.yeezy.com.mx>yeezy</a> to the organization. Trees are considered a defining component of many ecosystems through their role in carbon, water and nutrient cycles, soil formation and climate regulation. According to the U.S. Department of Agriculture Forest Service, 100 trees can remove 54 tons of carbon monoxide and 430 pounds of other air pollutants a year. Trees directly underpin the survival of so many species ndash; including many found on the IUCN Red List. Thriving, naturally diverse forests are essential in mitigating both climate change and biodiversity loss, and as such solutions for one crisis often have mutually reinforcing benefits for the other, said Dr. Dave Hole, vice president for global solutions at Conservation International s Moore Center for Science.
