This is out of an estimated 8 million animal and plant species, including 5.5 million insect species. The drivers of these extinctions are, in descending order: (1) changes in land and sea use; (2) direct exploitation of organisms; (3) climate change; (4) pollution and (5) invasive alien species. [6]
The impacts of invasive alien species on the economy has been wide-ranging, from management costs, to loss of crops, to infrastructure damage. The overall economic cost of invasions to Italy between 1990 and 2020 was estimated at US$819.76 million (EUR€704.78 million).
The invasion of alien species is one of the major drivers of biodiversity loss in general, and the second most common threat being related to complete species extinctions since the 16th century. Invasive alien species are also capable of reducing the resilience of natural habitats, and agricultural as well as urban areas, to climate change.
The European Union defines invasive alien species as those outside their natural distribution area that threaten biological diversity. [152] [153] Biotic invasion is considered one of the five top drivers of global biodiversity loss and is increasing because of tourism and globalization.
List of endangered species in Pakistan; Cheer pheasant pair from Himalaya. Cheer pheasant, which became extinct in Pakistan, was planned to be reintroduced in the region. The World Pheasants Association sent 90 eggs of the species to the Dhodial Pheasantry. Among the eggs which hatched, the mortality was high and remained high till 1995.
Biological pollution (impacts or bio pollution) is the impact of humanity's actions on the quality of aquatic and terrestrial environment.Specifically, biological pollution is the introduction of non-indigenous and invasive species, [1] otherwise known as Invasive Alien Species (IAS).
Species that are important to people as food, such as the golden mahseer and large freshwater shrimp (Macrobrachium species), are part of the abundant aquatic life. The west half of the Pakistan coast is in the south of Balochistan province. It is also called the Makran coast and exhibits protected sites such as Astola Island and Hingol ...
