The quiet collapse of insects
In German nature reserves, flying-insect biomass fell by 76% over 27 years — a warning for pollination and the food web.
How this affects people
Insects pollinate crops, recycle nutrients and feed birds, fish and bats. A long-term study in protected areas in Germany found three-quarters of flying-insect biomass had disappeared.
Because the study sites were protected reserves, the decline points to landscape-wide pressures such as pesticides and habitat loss.

What could happen next
The future leaves room for choices. Compare the outlooks, check what supports them and notice where the evidence becomes less certain
Monitoring expands
More countries start systematic insect monitoring to measure the trend.
The future is not a timetable. These summaries reflect published scenarios and trends, with deeper uncertainty at longer horizons. Choices made now matter.
