Mostly True

We lost 75% of insect biomass in the US in 30 years. No insects means no pollinators, no birds, and no food for us. This is bigger than just the bees. This is total collapse.

Studies have documented a decline of approximately 75% in flying insect biomass over about 27-30 years in specific regions such as Germany, and experts warn that such losses threaten pollinators, birds, and food security, indicating a serious ecological concern beyond just bees.

The reporting

What the Evidence Shows

The claim that there has been a 75% loss of insect biomass in the US over 30 years is broadly consistent with scientific findings, though the most robust data comes from studies conducted in Germany rather than the US specifically. According to a 2017 study published in PLOS ONE and reported by ScienceDaily and CNN, there was a documented decline of more than 75% in total flying insect biomass over 27 years in German protected areas. While this exact figure is not directly from US data, it is often cited as indicative of a global trend of insect decline. The claim that no insects means no pollinators, no birds, and no food for humans aligns with ecological understanding. Insects play critical roles as pollinators and as a food source for many bird species; their decline threatens ecosystem stability and food production. National Geographic and Business Insider articles emphasize the broader implications of insect declines, including risks to ecosystems and food security, supporting the claim's assertion that this issue is bigger than just bees.

The phrase "total collapse" is more interpretive but reflects the serious concern among scientists about cascading ecological effects if insect declines continue unchecked. However, it should be noted that while significant declines have been observed regionally, global data are still incomplete, and some insect populations remain stable or are less well studied.

In summary, the claim captures the essence of scientific findings on insect biomass decline and its ecological consequences but extrapolates regional data (Germany) to the US context without direct US-specific studies cited in the sources. The warning about ecosystem collapse is supported by expert opinion but remains a projection rather than an established fact.
