Assessing cumulative impacts on ecosystems is important because it helps identify the aggregate effects of multiple stressors over time, including pollution, habitat fragmentation, and resource extraction. This assessment allows environmental scientists and policy-makers to understand how these stressors interact and compound each other's effects, leading to more informed decisions regarding environmental management and protection strategies. Cumulative impact analysis is essential for effective conservation planning, identifying critical habitats, and prioritizing actions to mitigate adverse outcomes. By recognizing the cumulative impacts, we can enhance the resilience of ecosystems and promote sustainable practices.
