Global Insect Numbers Have Dropped
27 Percent Over 3 Decades, Study Finds The study can be found
in the journal, 'Science.' Data and research were gathered
from nearly 1,700 locations and
over 10,000 kinds of insects. The analysis claims that
populations are dropping by
just under one percent annually. Michigan State University butterfly expert
Nick Haddad calls the decline "jaw dropping." Nick Haddad, via NBC News The biggest drops were found in Europe
and North America, particularly the Midwest. Lead author and entomologist Roel van Klink
says croplands, urban and suburban areas
are where decreases were most notable. Van Klink adds that urbanization
and loss of habitat could be
main causes of the decline. While land insects have seen their numbers fall,
the study adds that populations for freshwater insects
have jumped one percent annually. These types of bugs, which include dragonflies and mosquitoes,
only make up a small part of the global insect world.
