Jul 4, 2024 · 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.
Biodiversity loss happens when plant or animal species disappear completely from Earth ( extinction) or when there is a decrease or disappearance of species in a specific area. Biodiversity loss means that there is a reduction in biological diversity in a given area. The decrease can be temporary or permanent.
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.
The main driver of biodiversity loss remains humans’ use of land – primarily for food production. Human activity has already altered over 70 per cent of all ice-free land. When land is...
Jul 4, 2024 · The loss of genes and individuals threatens the long-term survival of a species, as mates become scarce and risks from inbreeding rise when closely related survivors mate. The wholesale loss of populations also increases the risk that a particular species will become extinct. Biodiversity is critical for maintaining ecosystem health.
Biodiversity is rapidly declining worldwide, and there is considerable evidence that ecosystem functioning (e.g., productivity, nutrient cycling) and ecosystem stability (i.e., temporal...
Jan 22, 2024 · The loss of biodiversity affects the way an ecosystem functions, leading to species being less able to respond to changes in the environment and making them increasingly vulnerable to natural...
Sep 30, 2020 · Biodiversity loss, nature loss, it is at an unprecedented level in the history of mankind," says Elizabeth Mrema, the executive secretary of the Convention on Biological Diversity. "We're the...
Explore the diversity of wildlife across the planet. What are species threatened with? What can we do to prevent biodiversity loss?
Jun 6, 2012 · Two decades ago the first Earth Summit raised the question of how biological diversity loss alters ecosystem functioning and affects humanity; this Review looks at the progress made towards...
