Impacts on Habitats (Wikipedia)

The IPAT Formual

I = P × A × T

Where: I = Environmental impact, P = Population, A = Affluence (level of consumption), T = Technology (impact per unit of resource)

The extinction threat is estimated to range from 15 to 37 percent of all species by 2050,[42][43] or 50 percent of all species over the next 50 years.

The 6th Extinction

23% of all mammals and 12% of all birds are Red Listed by the International Union for Conservation of Nature (IUCN), meaning they too are threatened with extinction.

The Global Amphibian Assessment[26] reports that amphibians are declining on a global scale faster than any other vertebrate group, with over 32% of all surviving species being threatened with extinction

It is estimated that two-thirds of all mammal genera and one-half of all mammal species weighing at least 44 kilograms (97 lb) have gone extinct in the last 50,000 years.

The global extinction rate may be approximately 100,000 times higher than the natural background extinction rate

Conservation biologists are dealing with and have published evidence from all corners of the planet indicating that humanity may be causing the sixth and greatest planetary extinction event.

Status of oceans and reefs

90% of all of the large, open ocean tuna, billfishes, and sharks in the ocean are reportedly gone.

By 2000, 27% of the world's coral reef ecosystems had effectively collapsed.

Conservation Approaches

Ex-situ conservation

The process of protecting an endangered species of plant or animal outside of its natural habitat; for example, by removing part of the population from a threatened habitat and placing it in a new location, which may be a wild area or within the care of humans. While ex-situ conservation comprises some of the oldest and best known conservation methods, it also involves newer, sometimes controversial laboratory methods.

In-situ conservation

On-site conservation or the conservation of genetic resources in natural populations of plant or animal species, such as forest genetic resources in natural populations of tree species. It is the process of protecting an endangered plant or animal species in its natural habitat, either by protecting or cleaning up the habitat itself, or by defending the species from predators. It is applied to conservation of agricultural biodiversity in agroecosystems by farmers, especially those using unconventional farming practices.

Systematic conservation planning

1. Compile data on the biodiversity of the planning region 2. Identify conservation goals for the planning region 3. Review existing conservation areas 4. Select additional conservation areas 5. Implement conservation actions 6. Maintain the required values of conservation areas

Definition: the scientific study of the nature and status of Earth's biodiversity with the aim of protecting species, their habitats, and ecosystems from excessive rates of extinction.

Fungi are essential for sustainability of forests.

The value of insects in the biosphere is enormous because they outnumber all other living groups in measure of species richness. The greatest bulk of biomass on land is found in plants, which is sustained by insect relations.

What is habitat conservation? (Wikipedia)

A land management practice that seeks to conserve, protect and restore habitat areas for wild plants and animals, especially conservation reliant species, and prevent their extinction, fragmentation or reduction in range.
