From a population standpoint, insects rule our planet.
Scientists have named almost 900,000 different species of insects, but some
experts suggest that there may be as many as 30 million more species that
haven't yet been christened. These same scientists estimate that about 10
quintillion--that's 10 with 18 zeroes behind it--insects are alive on Earth at
this very minute. With numbers this staggering, it's no wonder that insects
affect our lives and civilization, influencing everything from religion to
agriculture to technology. Discover the 10 most common insects around us.
