The article discusses how scientists predicted changes in biodiversity for different ecosystems by studying global environmental factors like land use, climate, and species introductions. They looked at how sensitive each ecosystem is to these changes and estimated how biodiversity will be affected by 2100. The study found that different biomes will be impacted in various ways, with some being more sensitive to certain factors than others. Overall, the research provides insights into how biodiversity may change in the future based on current global trends.
