What are the drivers of biodiversity loss and how does climate change affect biodiversity?
Some drivers of biodiversity loss include the following: changing in both land and sea use, invasive species, and the exploitation of species. The 2nd question you asked provides the following answer. With every degree increase of warming, species will go extinct. Hope this helps.
The biggest driver of biodiversity loss is how people use the land and sea. This includes the conversion of land covers such as forests, wetlands and other natural habitats for agricultural and urban uses. Since 1990, around 420 million hectares of forest have been lost through conversion to other land uses. The main direct threats to conservation fall in eleven categories: Residential and commercial development; farming activities; energy production and mining; transportation and service corridors; biological resource usages; human intrusions and activities that alter, destroy. The main direct cause of biodiversity loss is land use change which drives an estimated 30% of biodiversity decline globally. Second is overexploitation (overfishing, overhunting and overharvesting) for things like food, medicines and timber which drives around 20%.The biggest driver of biodiversity loss is the way in which people use the land and sea. How we grow food, harvest materials such as wood or minerals from the ocean floor, and build our towns and cities all has an impact on the natural environmental and the biodiversity that lives there. Direct drivers of biodiversity and ecosystem change are land-use change, climate change, pollution, natural resource use and exploitation, and invasive species.Biodiversity, or the variety of all living things on our planet, has been declining at an alarming rate in recent years, mainly due to human activities, such as land use changes, pollution and climate change. Climate change has altered marine, terrestrial, and freshwater ecosystems around the world. It has caused the loss of local species, increased diseases, and driven mass mortality of plants and animals, resulting in the first climate-driven extinctions. The shrinkage of glaciers, decreasing water flow of the perennial rivers depleting ground water level directly and indirectly affect the biodiversity of the sub- region. Some of the most immediate effects of recent climate change are becoming apparent through affects on biodiversity. Many animal and plant species are likely to become extinct as ecosystems adjust to climate change. While adaptable species will survive, and other migrates, the end result will be lost biodiversity. Estimates show a 15% decrease in outdoor working capacity during daylight hours due to extreme heat by 2050,” . “The increased heat is expected to cost India 2.8% and 8.7% of its Gross Domestic Product (GDP) and depressed living standards by 2050 and 2100, respectively. The rise in global temperature, sea level, and extreme weather events can cause habitat loss, changes in the timing of seasonal events, and an increase in disease outbreaks, which can lead to the extinction of species.
