Red list categories of the IUCN Demonstrator against biodiversity loss, at Extinction Rebellion (2018).. The current rate of global biodiversity loss is estimated to be 100 to 1000 times higher than the (naturally occurring) background extinction rate, faster than at any other time in human history, [25] [26] and is expected to grow in the upcoming years.
These tend to be directly or indirectly connected to climate change and can cause a deterioration of forest ecosystems. [37] [38] Groups that care about the environment have been working for many years to stop the decrease in biodiversity. Nowadays, many global policies include activities to stop biodiversity loss.
[12] Chelonia mydas on a Hawaiian coral reef. Although the endangered species is protected, habitat loss from human development is a major reason for the loss of green turtle nesting beaches. Wetlands and marine areas have endured high levels of habitat destruction. More than 50% of wetlands in the U.S. have been destroyed in just the last 200 ...
Biodiversity’s economic resources are worth at around $150 trillion annually which is roughly twice the world’s GDP. [171] The loss of biodiversity is actually harming the GDP of the world by costing an estimated $5 trillion dollars annually. Business supply chains rely heavily on ecosystems remaining relatively maintained and nurtured.
Agricultural expansion continues to be the main driver of deforestation and forest fragmentation and the associated loss of forest biodiversity. [12] Large-scale commercial agriculture (primarily cattle ranching and cultivation of soya bean and oil palm) accounted for 40 percent of tropical deforestation between 2000 and 2010, and local ...
Summary of major biodiversity-related environmental-change categories expressed as a percentage of human-driven change (in red) relative to baseline (blue) It has been estimated that from 1970 to 2016, 68% of the world's wildlife has been destroyed due to human activity. [132] [133] In South America, there is believed to be a 70 percent loss. [134]
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
Causes of habitat fragmentation include geological processes that slowly alter the layout of the physical environment [3] (suspected of being one of the major causes of speciation [3]), and human activity such as land conversion, which can alter the environment much faster and causes the extinction of many species.
