Biodiversity Loss Old

Biodiversity is the variety of living organisms that exist and thrive in the world, including plants, animals, fungi, and microorganisms. As a result of climate change and human development, the biodiversity of ecosystems throughout the world has been lost. In 2022, the World Wildlife Fund’s Living Planet Report found that global populations of mammals, fish, birds, reptiles, and amphibians have declined an average of 69% since 1970 [1]. This is in large part due to repurposing of native habitat for human needs, like crop and livestock production. Poaching of already-endangered species, deforestation, and overfishing are direct human activities that contribute to a loss of organismal populations. Climate change has only exacerbated these problems, resulting in habitat loss after climate disasters, water pollution, and rising temperatures that increasingly make lands and waters uninhabitable to native species. These factors combine to cause population decline or extinction of biological life.

Living Planet Index [2]

The Living Planet Index is a measure designed to assess the state of the world's biological diversity and ecosystem health. It is a key component of the Living Planet Report, which is produced by the World Wildlife Fund in collaboration with the Zoological Society of London and other partners. The Index provides insights into trends in global biodiversity by tracking changes in populations of vertebrate species over time. It is a valuable tool for understanding the impact of human activities on wildlife. The index tracks population trends of thousands of vertebrate species, normalizing the data to account for variations in population size. The data spans from the year 1970 to the present, and describes vertebrate populations from locations across the globe.
