The Living Planet Report by the World Wildlife Fund

Global biodiversity has declined

The Living Planet Index reflects the overall health of our planet's biodiversity.

It works a bit like a stock exchange index, by tracking average changes in animal populations from around the world.
The 30% decline means that on average, species population sizes were 30% smaller in 2007 than in 1970.

This decline is seen in all biomes.

And is highest in freshwater habitats.

But the trend is not the same all over the world

Tropical and temperate regions show starkly divergent trends.

As do high-income and low- and middle-income countries.

Scroll over the map below to see the Living Planet Index in more detail in different habitat types in tropical and temperate areas.
