Human land-use is a primary cause of biodiversity loss. A recent study shows that human changes to ecosystems has pushed global biodiversity loss beyond safe limits, which could reduce nature’s resilience.
Increasing intensity of human land-use makes ecological communities progressively more similar to one another, leading to an overall loss of diversity. Ecological metrics used to quantify diversity loss could provide helpful conservation benchmarks.
Analysis of global forest cover reveals that over 70 percent of remaining forests are within 1 kilometer of non-forest edge. Synthesis of long-term studies show that this will result in pervasive loss of biodiversity and ecosystem services.
Species are going extinct 1,000 times faster than at any point in Earth's history, and even with protected areas, biodiversity preservation remains sub-optimal due to knowledge gaps and low representation of ecological habitats.
