- Overview
- Human beings and endangered species
An endangered species is any species that is at risk of extinction because of a rapid decrease in its population or a loss of its critical habitat.
What role does human activity play in causing species to become endangered?
Roughly 99 percent of threatened and endangered species are at risk because of human activities. The principal threats are habitat loss and degradation, the spread of invasive species, the growing influence of global warming, chemical pollution, unsustainable hunting, and disease.
What organizations determine which organisms are endangered species?
Among the organizations connected with assessing which organisms are endangered species are the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), the Convention on the Conservation of Migratory Species of Wild Animals (CMS), and the Red List of Threatened Species, created by the International Union for Conservation of Nature (IUCN).
endangered species, any species that is at risk of extinction because of a sudden rapid decrease in its population or a loss of its critical habitat. Biodiverse regions that require protection on the grounds that they host a significant number of endangered species are called hot spots.
Roughly 99 percent of threatened species are at risk because of human activities alone. By the early 21st century it could be said that human beings (Homo sapiens) are the greatest threat to biodiversity and are the major drivers of biodiversity loss. The principal threats to species in the wild are:
1.Habitat loss and habitat degradation
2.The spread of introduced species (that is, non-native species that negatively affect the ecosystems they become part of)
3.The growing influence of global warming and chemical pollution
4.Unsustainable hunting
5.Disease
Tackling threats that impact the Earth. WWF’s work addresses direct and indirect threats—and the forces that drive them—to conserve biodiversity and reduce humanity’s ecological footprint.

The IUCN Red List Categories and Criteria are intended to be an easily and widely understood system for classifying species at high risk of global extinction. It divides species into nine categories: Not Evaluated, Data Deficient, Least Concern, Near Threatened, Vulnerable, Endangered, Critically Endangered, Extinct in the Wild and Extinct .
Recognizing that the problems facing our planet are increasingly more complex and urgent, WWF focuses its work on six ambitious goals. Through this integrative approach, we can challenge the planet’s greatest threats and ensure a healthy future for people and nature.
