“The North American bird population has declined by 3 billion, or 27 percent, since 1970, according to an extensive study published Thursday in Science.”
Considering how many birds live by eating insects, it shouldn’t be a surprise that fewer bugs means fewer birds. In some regards, that is simplistic; but species are inter-connected. A decline in one can easily trigger and decline in another. Species around us are declining. We are a species. We’re getting enough warning. We shouldn’t be surprised anymore.
