Biodiversity refers to the variety and variability of life on Earth. Biodiversity typically measures variation at the genetic, species, and ecosystem level. Terrestrial. What is the link between biodiversity and ecosystem services? Biodiversity is the variability among living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity. The air you breathe, the water you drink and the food you eat all rely on biodiversity, but right now it is in crisis – because of us. What does this.
Biodiversity is the result of 3. It has been subject to periods of extinction. The latest and most destructive stage of extinction is Holocene extinction, which has occurred due to the impact of human beings on the environment. The role of biodiversity in the following areas will help make clear the importance of biodiversity in human life:. In , the terms threatened, endangered or rare were used to describe the status of many species. Factors identified by Edward Wilson are described by the acronym- HIPPO standing for habitat destruction, climate change , invasive species, pollution , human overpopulation and over-harvesting.
Habitat destruction is a major cause for biodiversity loss. Habitat loss is caused by deforestation , overpopulation, pollution and global warming.
Species which are physically large and those living in forests or oceans are more affected by habitat reduction. Fresh water ecosystems are nowadays the most threatened ecosystems. Invasive species refer to those that would normally remain constrained from an ecosystem because of the presence of natural barriers.
Since these barriers are no longer existing, invasive species invade the ecosystem, destroying native species. Human activities have been the major cause for encouraging invasive species. Species can also be threatened by genetic pollution- uncontrolled hybridization and gene swamping. For instance, abundant species can interbreed with rare species thus causing swamping of the gene pool. Over exploitation is caused by activities such as over fishing, over hunting, excessive logging and illegal trade of wildlife.
Global warming is also becoming a major cause for loss of biodiversity. For example if the present rate of global warming continues, coral reefs which are biodiversity hotspots will disappear in years. It also provides links to further information on biodiversity. Biodiversity is short for biological diversity. It describes the variety and diversity of all life on land, in fresh water and in the sea, including the places or ecosystems where they live and the genes they contain.
When we talk about biodiversity we generally think about the individual birds, plants, fish, insects and other species that are special to New Zealand - our indigenous biodiversity.
There are many examples, such as kiwi, tui, inanga whitebait , weta, and ti kouka cabbage tree. We also think of our distinctive ecosystems the interacting system of the living species and non-living parts such as air, nutrients and water such as forests, sand dunes and lakes.
Our biodiversity provides the life supporting systems that enable all organisms, including humans, to survive. The important resources and services, such as clean air and water, fertile soils, pollution and flood control provided by biodiversity underpins our economic and social sustainability. It also provides products such as timber, fuel, food and medicines.
Our farming, forestry and horticulture depend on the resources and services provided by biological systems. Other benefits include recreation, aesthetic, scientific, education and cultural values and a sense of identity.
Why Is Biodiversity Important? Who Cares?
Biodiversity: Biodiversity, the variety of life found in a place on Earth or, often, the total variety of life on Earth. A common measure of this variety. This huge variety of animals and plants, and the places they live, is called biodiversity. And, together, they provide us with essentials like food, drinking water. "I understand there may be a biodiversity crisis, but how does that affect me?” Well. You see. It's like this Biological diversity is the resource upon which families.
