We lost 75% of insect biomass

Multiple studies and reports indicate that insect biomass has declined by approximately 75% over the past few decades, particularly in certain regions and ecosystems.

The reporting

What the Evidence Shows

The claim that 'We lost 75% of insect biomass' is supported by several scientific studies and news reports. According to a study referenced by CNN and Beyond Pesticides, insect populations have declined by about 75% over the last 27 to 30 years, with some reports noting an 82% decline in flying insect biomass in specific areas such as Germany. This decline is attributed to factors like agricultural intensification, urbanization, and insufficient conservation efforts.

However, it is important to note that these figures often come from localized studies or specific ecosystems rather than a global comprehensive assessment. The decline is significant and alarming but may vary regionally.

Therefore, while the claim broadly reflects the findings of recent research on insect biomass loss, it simplifies a complex issue that involves geographic and ecological variability.
