Somehow, worries about wolves, turtles, and White rhinos are more likely to die than feeling overwhelmed by the elimination of bugs.
But the loss of insects is a threat threat – one that can trigger a "dense fall of Earth ecosystems," a new study that warns.
Research, its first global review of its kind, looks at 73 historical reports about the fall of insects all over the world and found that the total mass of all insects on the planet decreases by 2.5% per year.
If this trend continues, the Earth can not have any insects all come 2119.
"For 10 years you will have a quarter lower, in just 50 years and half left 1
That's a big problem, because insects are food sources for to countless birds, fish, and mammal species. Pollinators such as bees and butterflies also play an important role in the production of fruits, vegetables, and nut.
Insects will go eight times faster than mammals, birds, and reptiles
Sánchez-Bayo and his fellow authors focus on their assessment of insects in European countries and North America. They estimate that 41% of the insect species has dropped, 31% are at risk (according to the standards set by the International Union for Conservation of Nature), and 10% are locally available.
This annihilation is eight times faster than the observed speed of destruction for mammals, birds, and reptiles.
Studies indicate that bee varieties in the UK, Denmark, and North America have major hits – bumblebees, honey bees, and wild bee species all fall. In the US, the number of honey bee colonies dropped from 6 million in 1947 to 2.5 million six decades.
Moths and butterflies are also missing throughout Europe and the US. Between 2000 and 2009 alone, the UK lost 58% of the butterfly species in the farmed land.
Also appear dragonflies, mayflies, and beet dying.
When looking at all animal populations across the planet (not just insects), according to a 2017 study, Earth appears to be subject to a process of "biological annihilation." Assessment estimates that "50% of the number of individual animals that once shared Earth with us is gone."
Rapid decline in global biodiversity is sometimes called the "sixth annihilation," because it is the sixth time in the history of life on Earth that the planet's fauna has experienced a massive fall in numbers.
Previously, mass extinction was caused by the occurrence of ice age or asteroid collision. However, this mass destruction has been driven by human activities – especially reducing forests, mining, and carbon-dioxide emissions that contribute to global warming.
"As insects are made up of 2/3 of all types of terrain on Earth, the above patterns prove that the occurrence of six major extinction affects the forms of life on our planet , "wrote the authors.

& # 39; Catastrophic consequences for … the survival of mankind & # 39;
Studies emphasize that insects are "essential for the proper functioning of all ecosystems" sources, crop pollinators, pest control, and soil nutrient recyclers.
"If the loss of insect species is uncontrollable, it will have a catastrophe for both the planet's ecosystems and for the safety of mankind," Sánchez-Bayo told the Guardian.
Large declines in insect populations threaten food, timber, and fiber that mankind's safety depends on, according to Timothy Schowalter, professor of entomology at Louisiana State University.
"The pollinator ignores 35% of our global food supply, so European countries provide protection and restoration of pollinator habitats," he told Business Insider.
Schowalter added that insects are a critical food source for many birds, fish and other vertebrates, which will disappear if their dietary origin is done.
"Insects are often betrayed, or at least their significant contribution to ecosystem productivity and delivery of ecosystem services are undervalued," Schowalter says. "In other words, if insects and other arthropods are dropped, our safety is dangerous."
This is not the first time scientists call the increasing population of insects.
In 2017, a study showed that 75% of Germany's flying insects have disappeared since the 1990's. Another recent study showed that the total biomass of arthropods – such creatures insects, spiders, and lobsters with legs but no backbone – in Puerto Rico got a nose dive since the 1970s.
Pesticides and fertilizers, along with heavy use of land for farming, are major drivers of this decline.
"In general, systematic, widespread and frequent use of pesticides in agriculture and pasture over the past 60 years negatively affects most organisms, from insects to birds and bats," written by authors of the new study.
They added: "The conclusion is clear: unless we change our way of making food, insects altogether will go to the path of extinction in decades."
Sánchez-Bayo told the Guardian that he thinks insecticides such as neonicotinoids and fipronil are especially harmful.
"They overpowered the land, killed all the criminals," he said.
Climate change temperatures are releasing the role of insect deaths, although this is not the main reason. "Today's downturns are largely associated with land use changes, especially in agricultural intensification, forest division and city development, rather than changing temperatures," Schowalter said.
