In the summer of 1875, it took a swarm of about 10 billion locusts close to a week to pass through Plattsmouth, Nebraska. Some 30 years later, the species went extinct, leaving the ecosystem damaged since they provided food for many insectivores.<\/span><\/p>\n Some more recent <\/span>insect population statistics<\/span> are even scarier. Namely, 40% of all insect species are in decline or on the verge of extinction.<\/span><\/p>\n Should we worry? Yes! And here\u2019s why:<\/span><\/p>\n Everyone knows that <\/span>bees are dying in high numbers<\/span><\/a> and that we\u2019d be left with minimal food sources if they disappeared completely. But should we worry about the ladybugs and butterflies in the same way we worry about bees?<\/span><\/p>\n Keep reading if you want to find out why insects are important and how their disappearance would affect the world.\u00a0<\/span><\/p>\n Insects are the most diverse group of animals, with the highest number of species. But how many of them are there?\u00a0<\/span><\/p>\n (Scientific American)<\/span><\/p>\n Contrary to popular belief, insects are the dominant form of animal life on Earth. Compared to 5,416 species of mammals, almost a million insect species have been described so far.<\/span><\/p>\n And according to the <\/span>insect population<\/span> data, there could be up to 30 million species of insects.\u00a0<\/span><\/p>\n (The Guardian)<\/span><\/p>\n The world’s insect species are moving towards extinction at worrying rates. According to the research, their extinction rate is eight times faster than those of mammals, reptiles, and birds. At this rate, insects could disappear within 100 years.<\/span><\/p>\n (National Geographic)<\/span><\/p>\n Following several high-profile papers on this topic, a group of European researchers discovered that this staggering decline happened over just 27 years within 63 protected areas of Germany.<\/span><\/p>\n (PNAS)<\/span><\/p>\n Rainforests are known for being the <\/span>most biologically diverse regions in the world<\/span><\/a>. <\/span>Insect biomass<\/span> has always been one of the most significant parts of that diversity. The temperature of the rainforest has been rising since the 1970s, causing its food chain to collapse.<\/span><\/p>\n From this, it\u2019s clear that <\/span>global warming affects all species on the planet<\/span><\/a>.<\/span><\/p>\n (ENTSOC, Scientific American)<\/span><\/p>\n However, scientists believe that the number is higher. There are several reasons behind this underrepresentation, like habitat specificity or dependence on a host plant or animal that is rare. But is the <\/span>insect apocalypse debunked<\/span> with the data? The answer is complicated.<\/span><\/p>\n The data clearly shows that some insect species are declining dramatically. But these statistics might be location-specific and not a global trend. In some cases, they don\u2019t even indicate a local problem.<\/span><\/p>\n Even though we might not see an insect apocalypse, many insect species are still dying out at alarming rates. There are numerous reasons behind this trend.<\/span><\/p>\n One of the most apparent reasons for the decline in insect population is the use of pesticides. The <\/span>loss of habitat can also endanger the existence of a species<\/span><\/a>, as well as habitat degradation and the decline and disappearance of plants and animals that insects depend on for food and shelter.<\/span><\/p>\nTop 10 Statistics <\/span>Insect Populations\u00a0<\/span><\/h2>\n
