This interactive graphic is based on the Living Planet Index, developed by Zoological Society of London (ZSL) and World Wide Fund for Nature (WWF). It illustrates the average change in population sizes of native animal species over time by resizing animal silhouettes.

• Data source: Living Planet Index (ZSL & WWF, 2024).
• Interpretation: Indices are relative (1970 baseline = 1.0) and represent trends, not absolute counts of individual animals.
