# United Nations secretary general, António Guterres, has warned that biodiversity loss is a global crisis no nation can ignore. Today is International Day for Biological Diversity under the theme, Harmony with nature and sustainable development. One million species are at risk of extinction, while 75-percent of land ecosystems and two-thirds of marine environments have been significantly altered by human activity. Guterres says living in harmony with nature and sustainable development is humanity’s path to a better world for all.
