  bet365 live casino games Recent,The official website of York University in the United Kingdom is called,The school's Revices Researcher of the Human Biological Diversity Center of the Human Biological Diversity of the Human World Biology Center, Inês Martins and German Comprehensive Biological Diversity Research Center、Research on cooperative studies such as Martin Luther Hallevet Teng Berge University in Germany,To the middle of this century,Climate change will become the main reason for the loss of biodiversity,However, human beings still have time to take measures to reduce the impact of climate change on global ecosystems and species。

The speed of the loss of biological diversity in the 20th century,enough to be called the sixth biological extinction,Climate change in the 21st century further threatens species diversity and ecosystem services。To make the most comprehensive assessment of global biodiversity trends,Researchers combined with 13 different models to predict the loss of biological diversity in 2050 and changes in ecosystem services,and compare with changes from 1900 to 2015。

Based on a series of indicators,Results show,Like cutting forests、The change in the use of land and other land such as farmland is the biggest bet365 live casino games driving factor for the current loss of biodiversity,It may have caused global biodiversity to decrease by 2%to 11%。but but,Although the changes in land use are still related to biological diversity,But by 2050,Climate change will become a factor that brings more pressure to biodiversity and ecosystem services。

Researchers' assessment scope includes from sustainable development scenarios to high -emission scenarios,In all cases,The changes in land use and the comprehensive impact of climate change will cause the loss of biodiversity in all areas of the world。Although the overall decline is consistent,But in different regions、There are considerable differences between different models and different scenarios。

bet365 Play online games Researchers said,Looking forward to the future,Sustainable development policy may slow down biodiversity loss caused by factors such as land use changes。​​but,The negative effects of climate change on biodiversity will seem increased,It is particularly serious under high emissions。

Researchers mentioned,Even the most sustainable assessment plan,Nor did it list all policies that can protect biodiversity in the next decades。For example,Biological energy is a key component of sustainable development plan,It helps to slow climate change,But it will also reduce the habitat of species。other,Evaluate the impact of specific policies on biological diversity will help determine which policies are the most effective on protecting bet365 Play online games and promoting biodiversity and ecosystem services。

Researchers added,Their modeling still has uncertainty,but can also be effectively prove,To achieve the goal of the "Biological Diversity Convention",It also needs to make more efforts in terms of policy。Martinis said,The purpose of this research is not predicting what will happen in the future,On the contrary,Its purpose is to explore alternative solutions,Let environmental protection go to the road that points to a positive end,To avoid those unacceptable results。
