Biodiversity loss not only results in species extinction, but it also affects humans by depriving humanity from accessing services that natural ecosystems provide, whether it be the wealth of oxygen that we breathe or the benefits of pollination provided by animals in ensuring global food security.
Biodiversity loss, the reduction in an area’s biodiversity (the number of genes, species, individual organisms, or ecosystems) expressed by species loss, population declines and reductions in the genetic diversity within a species, and the collapse of biological communities.
WWF’s 2020 Living Planet Report held some alarming news: The world has seen an average 68% drop in mammal, bird, fish, reptile, and amphibian populations since 1970. Much of the loss is caused by habitat destruction due to unsustainable agriculture or logging.
Biodiversity loss, however, is not just confined to the land. Life in the oceans is being threatened by overfishing, habitat degradation, pollution, and acidification due to rising carbon dioxide levels in the sea water. Corals, for example, have undergone dramatic declines since the mid-1990s.
Charts from the WWF’s Living Planet Report 2022 outline the scale of biodiversity loss - and suggest what can be done to become ‘nature positive’ by 2030.
The planet is experiencing a dangerous decline in nature. One million species are threatened with extinction, soils are turning infertile, and water sources are drying up. The Global Biodiversity Framework – adopted by world leaders in December 2022 – sets out to halt and reverse nature loss by 2030.
Large-scale biodiversity loss is not inevitable, argues David Banks, TNC’s chief conservation officer, if we can quickly mobilize global efforts to protect 30% of the world's lands and waters by 2030. ... The Okavango is one of countless examples of how you can’t talk about biodiversity without including the global effects of climate change ...
Biodiversity is rapidly declining worldwide, and there is considerable evidence that ecosystem functioning (e.g., productivity, nutrient cycling) and ecosystem stability (i.e., temporal...
Nature loss has far-reaching consequences. Damaged ecosystems exacerbate climate change, undermine food security and put people and communities at risk. Around 3.2 billion people, or 40 percent of the global population, are adversely affected by land degradation.
The World Wide Fund for Nature’s Living Planet Report 2022 documents a 69% average loss in the abundance of mammal, bird, reptile, fish and amphibian species since 1970. The populations of vertebrates living in freshwater ecosystems have declined even more, by 83% on average over the same period.
