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.
The report concluded that global warming of 2 °C (3.6 °F) over the preindustrial levels would threaten an estimated 5% of all the Earth's species with extinction even in the absence of the other four factors, while if the warming reached 4.3 °C (7.7 °F), 16% of the Earth's species would be threatened with extinction.
Climate change threatens people with increased flooding, extreme heat, increased food and water scarcity, more disease, and economic loss. Human migration and conflict can also be a result. [13] The World Health Organization calls climate change one of the biggest threats to global health in the 21st century. [14]
Environmental issues in the Philippines. Today, environmental problems in the Philippines include pollution, mining and logging, deforestation, threats to environmental activists, dynamite fishing, landslides, coastal erosion, biodiversity loss, extinction, global warming and climate change. [1][2][3] Due to the paucity of extant documents, a ...
[28] [29] [30] One well known example of a species affected is the polar bear, whose habitat in the Artic is threatened. [31] Algae can also be affected when it grows on the underside of sea ice. [32] Warm-water coral reefs are very sensitive to global warming and ocean acidification.
The Global Assessment Report on Biodiversity and Ecosystem Services, published by the United Nation's IPBES in 2019, posits that roughly one million species of plants and animals face extinction from anthropogenic causes, such as expanding human land use for industrial agriculture and livestock rearing, along with overfishing. [10] [11] [12]
Extinction is the termination of a taxon by the death of its last member. A taxon may become functionally extinct before the death of its last member if it loses the capacity to reproduce and recover. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively.
Climate change is having serious impacts in the Philippines such as increased frequency and severity of natural disasters, sea level rise, extreme rainfall, resource shortages, and environmental degradation. [ 1 ] All of these impacts together have greatly affected the Philippines' agriculture, water, infrastructure, human health, and coastal ...
