Humanity depends on healthy ecosystems that support and improve our quality of life. Without healthy ecosystems, the Earth will be uninhabitable for human life. The Living planet Index shows that currently wild species and natural ecosystems are under pressure across all biomes and regions of the world. This stems from the growing human population and its demand on the biosphere. Direct anthropogenic threats to biodiversity can generally be grouped under the following five headings:
- Habitat loss, fragmentation or change, especially due to agriculture
- Overexploitation of species, especially due to fishing and hunting
- Pollution
- The spread of invasive species or genes
- Climate change
