Business Insider reports a recent loss of insects may be more of a threat than may be believed.
Studies suggest this could trigger a "catastrophic collapse of Earth's ecosystems."
The research looked at 73 historical reports on insect declines around the world...
...and discovered the total mass of all insects is decreasing by 2.5% each year.
This means the Earth may not have any insects at all by 2119, which could significantly affect ecosystems worldwide.
