Taking into account the relative frequencies, many biodiversity indexes have been developed. Raw counts may not be as ecologically relevant as relative or absolute abundances. Locally bounded loss rates can be measured using species richness and its variation over time. These rapidly rising extinction trends impacting numerous animal groups including mammals, birds, reptiles, amphibians and ray-finned fishes have prompted scientists to declare a contemporary biodiversity crisis. The current rate of global diversity loss is estimated to be 100 to 1000 times higher than the (naturally occurring) background extinction rate, faster than at any other time in human history, and expected to still grow in the upcoming years. Sir Peter Scott, Founder of the World Wide Fund for Nature, Cosmos Magazine, 2010 However, the United Nations Environment Programme report on "Making Peace with Nature" released in 2020 found that most of these efforts had failed to meet their international goals. The international commitment and goals for this work is currently embodied by Sustainable Development Goal 15 "Life on Land" and Sustainable Development Goal 14 "Life Below Water". For example, the UN Convention on Biological Diversity is focused on preventing biodiversity loss and proactive conservation of wild areas. International environmental organizations have been campaigning to prevent biodiversity loss for decades, public health officials have integrated it into the One Health approach to public health practice, and increasingly preservation of biodiversity is part of international policy. Reduced biodiversity in particular leads to reduced ecosystem services and eventually poses an immediate danger for food security, but also can have more lasting public health consequences for humans. Ecological effects of biodiversity are usually counteracted by its loss. Įven though permanent global species loss is a more dramatic and tragic phenomenon than regional changes in species composition, even minor changes from a healthy stable state can have dramatic influence on the food web and the food chain insofar as reductions in only one species can adversely affect the entire chain ( coextinction), leading to an overall reduction in biodiversity, possible alternative stable states of an ecosystem notwithstanding. The current global extinction (frequently called the sixth mass extinction or Anthropocene extinction), has resulted in a biodiversity crisis being driven by human activities which push beyond the planetary boundaries and so far has proven irreversible. The latter phenomenon can be temporary or permanent, depending on whether the environmental degradation that leads to the loss is reversible through ecological restoration/ ecological resilience or effectively permanent (e.g.

But with the next major update (which will still take some time), they can be traversed and used to your advantage.Summary of major biodiversity-related environmental-change categories expressed as a percentage of human-driven change (in red) relative to baseline (blue)īiodiversity loss includes the worldwide extinction of different species, as well as the local reduction or loss of species in a certain habitat, resulting in a loss of biological diversity. So far, oceans have been mostly inaccessible terrain. Sneak peak into upcoming ocean related gameplay Thank you for the feedback on this update, and we’re happy that most of you seem to be enjoying it. This is a digital library accessible from the main menu where you can read about all the projects, leaders and lifeforms you’ve encountered so far. They have an everlasting effect on the rest of your game and allow you to specialize more in specific strategies. Technologies are suggested at specific moments and can be researched with science.
