Global map reveals ‘unsafe levels’ of biodiversity across 58pc of Earth’s surface
Biodiversity has dropped below the “safe limit” across 58 per cent of the Earth’s surface, according to the most comprehensive analysis of global data to date.
- Planet’s “safe limits” exceeded if less than 90 per cent abundance of original species or 80 per cent of those species is retained
- Analysis found average local abundance of species across the world was 84.6 per cent
- Other experts say study is a warning but more work needed to clarify
