The world바카라s vital insect kingdom is undergoing 바카라death by a thousand cuts바카라. Climate change, insecticides, herbicides, light pollution, invasive species and changes in agriculture and land use are causing Earth to lose probably one per cent to two per cent of its insects each year, says University of Connecticut entomologist David Wagner, lead author in the special package of 12 studies in Proceedings of the National Academies of Sciences written by 56 scientists from around the globe.
The problem, sometimes called the insect apocalypse, is like a jigsaw puzzle. And scientists say they still don바카라t have all the pieces, so they have trouble grasping its enormity and complexity and getting the world to notice and do something, reports the Associated Press. Wagner says scientists need to figure out if the rate of the insect loss is bigger than with other species. 바카라There is some reason to worry more because they are the target of attack바카라 with insecticides, herbicides and light pollution.
Co-author and University of Illinois entomologist May Berenbaum, a National Medal of Science winner, says, 바카라Insect decline is kind of comparable to climate change 30 years ago because the methods to assess the extent, the rate (of loss) were difficult.바카라 Making matters worse is that in many cases, people hate bugs, even though they pollinate the world바카라s foods, are crucial to the food chain and get rid of waste, she says. Insects 바카라are absolutely the fabric by which Mother Nature and the tree of life are built바카라.
Two well known ones바카라honeybees and Monarch butterflies바카라best illustrate insect problems and declines. Honeybees have been in dramatic decline because of disease, parasites, insecticides, herbicides and lack of food. Climate change-driven drier weather in the US West means less milkweed for butterflies to eat. And changes in American agriculture remove weeds and flowers they need for nectar. 바카라We바카라re creating a giant biological desert except for soybeans and corn in a giant area of the Midwest,바카라 Wagner says.
University of Delaware entomologist Doug Tallamy, who wasn바카라t part of the studies, says the data highlights how the world has 바카라spent the last 30 years spending billions of dollars finding new ways to kill insects and mere pennies working to preserve them바카라. 바카라The good news is, with the exception of climate change, individuals can do much to reverse insect declines,바카라 Tallamy says. 바카라This is a global problem with a grassroots solution.바카라Ā
