Here are seven facts about global species decline in 2024:
1. Dramatic Decline in Vertebrate Populations: Populations of mammals, birds, fish, amphibians, and reptiles have shrunk by an average of 73% over the past 50 years. Freshwater ecosystems are particularly affected, with an 85% decline.
2. Regional Differences: The most significant losses have occurred in Latin America and the Caribbean, with a 95% decline, followed by Africa at 76% and the Asia-Pacific region at 60%.
3. Main Causes of Species Decline: Changes in land use, particularly from agriculture and urbanization, are the primary drivers of species loss. Other factors include overexploitation, pollution, invasive species, and climate change.
4. Climate Change as an Accelerating Factor: Climate change is exacerbating biodiversity loss by altering habitats and increasing the frequency of extreme weather events. Many species are struggling to adapt quickly enough.
5. Invasive Species on the Rise: Nearly 200 new species invade areas where they did not previously exist every year. These invasive species disrupt native ecosystems and often displace local wildlife.
6. Conservation Successes: Despite the negative trends, there have been positive outcomes. Some species, such as the Eurasian beaver, are making a comeback thanks to targeted conservation efforts.
7. International Efforts: The UN Biodiversity Conference adopted a global framework aimed at halting species loss by 2030. This agreement represents a significant step forward in global conservation.
These facts highlight the urgent need to intensify global efforts to protect biodiversity.
