“Unless we change our ways of producing food, insects as a whole will go down the path of extinction in a few decades,” they write. “The repercussions this will have for the planet’s ecosystems are catastrophic to say the least.”
The analysis, published in the journal Biological Conservation, says intensive agriculture is the main driver of the declines, particularly the heavy use of pesticides. Urbanisation and climate change are also significant factors.
The world’s insects are hurtling down the path to extinction, threatening a “catastrophic collapse of nature’s ecosystems”, according to the first global scientific review.
More than 40% of insect species are declining and a third are endangered, the analysis found. The rate of extinction is eight times faster than that of mammals, birds and reptiles. The total mass of insects is falling by a precipitous 2.5% a year, according to the best data available, suggesting they could vanish within a century.

The planet is at the start of a sixth mass extinction in its history, with huge losses already reported in larger animals that are easier to study. But insects are by far the most varied and abundant animals, outweighing humanity by 17 times. They are “essential” for the proper functioning of all ecosystems, the researchers say, as food for other creatures, pollinators and recyclers of nutrients.

The fields outside Kotawaringin village in Central Kalimantan, on the island of Borneo, looked as if they had just been cleared by armies. None of the old growth remained — only charred stumps poking up from murky, dark pools of water. In places, smoke still curled from land that days ago had been covered with lush jungle. Villagers had burned it all down, clearing the way for a lucrative crop whose cultivation now dominates the entire island: the oil-palm tree.
The dirt road was ruler straight, but deep holes and errant boulders tossed our tiny Toyota back and forth. Trucks coughed out black smoke, their beds brimming over with seven-ton loads of palm fruit rocking back and forth on tires as tall as people. Clear-cut expanses soon gave way to a uniform crop of oil-palm groves: orderly trees, a sign that we had crossed into an industrial palm plantation. Oil-palm trees look like the coconut-palm trees you see on postcards from Florida — they grow to more than 60 feet tall and flourish on the peaty wetland soil common in lowland tropics. But they are significantly more valuable. Every two weeks or so, each tree produces a 50-pound bunch of walnut-size fruit, bursting with a red, viscous oil that is more versatile than almost any other plant-based oil of its kind. Indonesia is rich in timber and coal, but palm oil is its biggest export. Around the world, the oil from its meat and seeds has long been an indispensable ingredient in everything from soap to ice cream. But it has now become a key ingredient of something else: biodiesel, fuel for diesel engines that has been wholly or partly made from vegetable oil.
Finally we emerged, and as we crested a hill, the plantations fell into an endless repetition of tidy bunches stretching for miles, looking almost like the rag of a Berber carpet. Occasionally, a shard of an old ironwood tree shot into the air, a remnant of the primordial canopy of dense rain forest that dominated the land until very recently.

Helping these tiny helpers can take only a small effort, he said. Habitat restoration can be as simple as a garden with plants that flower throughout the year. Unlike mammals, insects don’t require vast tracts of land to be satisfied — a back yard blooming with native flowers will do.
Not long ago, a lengthy drive on a hot day wouldn’t be complete without scraping bug guts off a windshield. But splattered insects have gone the way of the Chevy Nova — you just don’t see them on the road like you used to.
Biologists call this the windshield phenomenon. It’s a symptom, they say, of a vanishing population.
“For those of us who look, I think all of us are disturbed and all of us are seeing fewer insects,” said Scott Black, executive director of the Portland, Ore.-based Xerces Society, a nonprofit environmental group that promotes insect conservation. “On warm summer nights you used to see them around streetlights.”
The windshield phenomenon is not just a trick of Trans Am nostalgia. A small but growing number of scientific studies suggest that insects are on the wane.
“The windscreen phenomenon is probably one of the best illustrative ways to realize we are dealing with a decline in flying insects,” said Caspar Hallmann, an ecologist at Radboud University in the Netherlands. Hallmann is part of a research team that recently waded through 27 years’ worth of insects collected in German nature preserves.
Between 1989 and 2016, according to a report published Wednesday in the journal PLOS One, the biomass of flying insects captured in these regions decreased by a seasonal average of 76 percent.

The world’s chocolate industry is driving deforestation on a devastating scale in West Africa, the Guardian can reveal. Cocoa traders who sell to Mars, Nestlé, Mondelez and other big brands buy beans grown illegally inside protected areas in the Ivory Coast, where rainforest cover has been reduced by more than 80% since 1960. Illegal product is mixed in with “clean” beans in the supply chain, meaning that Mars bars, Ferrero Rocher chocolates and Milka bars could all be tainted with “dirty” cocoa. As much as 40% of the world’s cocoa comes from Ivory Coast.
The Guardian travelled across Ivory Coast and documented rainforests cleared for cocoa plantation; villages and farmers occupying supposedly protected national parks; enforcement officials taking kickbacks for turning a blind eye to infractions and trading middlemen who supply the big brands indifferent to the provenance of beans.
When approached for comment, Mars, Mondelez and Nestlé, and traders Cargill and Barry Callebaut did not deny the specific allegation that illegal deforestation cocoa had entered their supply chains. All said they were working hard to eradicate the commodity from their products.

Kellie Anderson stands in the understory of a century-old forest in eastern Napa County, about 70 miles north of San Francisco. To her left is a creek gully, a rush of the water audible through the thick riparian brush. The large trees here provide a home for deer, mountain lions, and endangered spotted owls, while the stream supports the last remnants of the Napa River watershed’s nearly extinct steelhead trout.
“They want to take all of this out,” says Anderson, who sits on the steering committee of a local environmental organization, Save Rural Angwin, named for a community in the renowned wine country of the Napa Valley. She is studying a project-planning map of the area as she waves her free arm toward the wooded upward slope. “It looks like this will be the edge of a block of vines,” she says.
Anderson and two fellow activists, Jim Wilson and Mike Hackett, were visiting a property of several dozen acres that the owners plan to clear and replant with grapes, the county’s principal crop. The project is one of many like it that are now pending approval by Napa County officials, who rarely reject a vineyard conversion project in the Napa Valley, a fertile strip that runs northward from the shores of San Francisco Bay.
In Napa County, neighboring Sonoma County, and farther to the north in the Willamette Valley of Oregon, concern is growing among some residents, environmentalists, and scientists about the expansion of vineyards into forested regions and the impacts on watersheds and biodiversity. In Napa, an aerial view reveals a carpet of vines on the valley floor, which is why winemakers hoping to plant new vines increasingly turn to land in the county’s wooded uplands. At these higher elevations, “about the only thing standing in the way of winemakers are the trees,” says Hackett.

“When the plants go extinct, the animals that depend on them go extinct. And it’s completely ignored,” [McNamara] said. “Most biologists who are aware of this are convinced that by the end of the century, if current trends continue, we will lose half of all animals and half of all plants will be gone.”
For a onetime landscaper from California, it was a Cinderella moment — standing beneath the glass vaulted ceiling of the Edwardian Lindley Hall in London, accepting one of the world’s highest honors in horticulture.
The crowd that applauded American Bill McNamara as he accepted the prestigious Veitch Medal from the Royal Horticultural Society on Feb. 22, included finely dressed members of England’s titled gentry and some of the biggest names in the botanical realm over which Great Britain still rules.
“It was such a big honor, it was a shock,” said McNamara, now comfortably back in his bluejeans at Quarryhill Botanical Garden, a refuge for rare and endangered Asian plants that he gathered himself from seed in wild and remote corners of China. In just 30 years, a mere baby in the world of botanical gardens, Quarryhill has come to be considered one of the most significant collections of its kind in the world, numbering close to 2,000 species plants in their natural form, unchanged by man through hybridization.

A cloud of uncertainty hangs over the hundreds of Sonoma County residents who grow marijuana for a living as the county bureaucracy continues a rapid march toward regulating their well-known but largely invisible industry.
More than 200 people attended a Cannabis Community Meeting held by county officials Thursday night at the Glaser Center in Santa Rosa to explain a proposed land use ordinance just six days after it was released and two months before the Board of Supervisors is scheduled to enact it.
Public workshops on the ordinance regulating medical marijuana were held around the county in July and August.
“This is not perfect by any means, but it is a first step,” Board Chairman Efren Carrillo said, noting there is a “bright future” for cannabis in the county that abuts the famed Emerald Triangle pot-growing region.
When the meeting ended, Cory Bohn, a west county marijuana farmer for 15 years, said he wasn’t sure if he would fit in under the proposed regulations that dictate where the psychoactive herb can be grown.
“Prohibition’s over but there’s still a lot of rules,” Bohn said. “I want to be compliant but I have a family of five to support.”
Bohn said he grows marijuana in a rural residential area, in a land-use zone that is likely to generate the most debate over the county’s zoning plan.
