UN report says nature is in worst shape in human history

Published

9 minute read

Nature is in more trouble now than at any other time in human history, with extinction looming over 1 million species of plants and animals, scientists said Monday in the United Nations’ first comprehensive report on biodiversity.

It’s all because of humans, but it’s not too late to fix the problem, the report said.

Species loss is accelerating to a rate tens or hundreds of times faster than in the past, the report said. More than half a million species on land “have insufficient habitat for long-term survival” and are likely to go extinct, many within decades, unless their habitats are restored. The oceans are not any better off.

“Humanity unwittingly is attempting to throttle the living planet and humanity’s own future,” said George Mason University biologist Thomas Lovejoy, who has been called the godfather of biodiversity for his research. He was not part of the report.

“The biological diversity of this planet has been really hammered, and this is really our last chance to address all of that,” Lovejoy said.

Conservation scientists from around the world convened in Paris to issue the report, which exceeded 1,000 pages. The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) included more than 450 researchers who used 15,000 scientific and government reports. The report’s summary had to be approved by representatives of all 109 nations.

Some nations hit harder by the losses, like small island countries, wanted more in the report. Others, such as the United States, were cautious in the language they sought, but they agreed “we’re in trouble,” said Rebecca Shaw, chief scientist for the World Wildlife Fund, who observed the final negotiations.

“This is the strongest call we’ve seen for reversing the trends on the loss of nature,” Shaw said.

The findings are not just about saving plants and animals, but about preserving a world that’s becoming harder for humans to live in, said Robert Watson, a former top NASA and British scientist who headed the report.

“We are indeed threatening the potential food security, water security, human health and social fabric” of humanity, Watson told The Associated Press. He said the poor in less developed countries bear the greatest burden.

The report’s 39-page summary highlighted five ways people are reducing biodiversity:

— Turning forests, grasslands and other areas into farms, cities and other developments. The habitat loss leaves plants and animals homeless. About three-quarters of Earth’s land, two-thirds of its oceans and 85% of crucial wetlands have been severely altered or lost, making it harder for species to survive, the report said.

— Overfishing the world’s oceans. A third of the world’s fish stocks are overfished.

— Permitting climate change from the burning of fossil fuels to make it too hot, wet or dry for some species to survive. Almost half of the world’s land mammals — not including bats — and nearly a quarter of the birds have already had their habitats hit hard by global warming.

— Polluting land and water. Every year, 300 to 400 million tons of heavy metals, solvents and toxic sludge are dumped into the world’s waters.

— Allowing invasive species to crowd out native plants and animals. The number of invasive alien species per country has risen 70% since 1970, with one species of bacteria threatening nearly 400 amphibian species.

Fighting climate change and saving species are equally important, the report said, and working on both environmental problems should go hand in hand. Both problems exacerbate each other because a warmer world means fewer species, and a less biodiverse world means fewer trees and plants to remove heat-trapping carbon dioxide from the air, Lovejoy said.

The world’s coral reefs are a perfect example of where climate change and species loss intersect. If the world warms another 0.9 degrees (0.5 degrees Celsius), which other reports say is likely, coral reefs will probably dwindle by 70% to 90%, the report said. At 1.8 degrees (1 degree Celsius), the report said, 99% of the world’s coral will be in trouble.

“Business as usual is a disaster,” Watson said.

At least 680 species with backbones have already gone extinct since 1600. The report said 559 domesticated breeds of mammals used for food have disappeared. More than 40% of the world’s amphibian species, more than one-third of the marine mammals and nearly one-third of sharks and fish are threatened with extinction.

The report relies heavily on research by the International Union for the Conservation of Nature, or IUCN, which is composed of biologists who maintain a list of threatened species.

The IUCN calculated in March that 27,159 species are threatened, endangered or extinct in the wild out of nearly 100,000 species biologists examined in depth. That includes 1,223 mammal species, 1,492 bird species and 2,341 fish species. Nearly half the threatened species are plants.

Scientists have only examined a small fraction of the estimated 8 million species on Earth.

The report comes up with 1 million species in trouble by extrapolating the IUCN’s 25% threatened rate to the rest of the world’s species and using a lower rate for the estimated 5.5 million species of insects, Watson said.

Outside scientists, such as Lovejoy and others, said that’s a reasonable assessment.

The report gives only a generic “within decades” time frame for species loss because it is dependent on many variables, including taking the problem seriously, which can reduce the severity of the projections, Watson said.

“We’re in the middle of the sixth great extinction crisis, but it’s happening in slow motion,” said Conservation International and University of California Santa Barbara ecologist Lee Hannah, who was not part of the report.

Five times in the past, Earth has undergone mass extinctions where much of life on Earth blinked out, like the one that killed the dinosaurs. Watson said the report was careful not to call what’s going on now as a sixth big die-off because current levels don’t come close to the 75% level in past mass extinctions.

The report goes beyond species. Of the 18 measured ways nature helps humans, the report said 14 are declining, with food and energy production noticeable exceptions. The report found downward trends in nature’s ability to provide clean air and water, good soil and other essentials.

Habitat loss is one of the biggest threats, and it’s happening worldwide, Watson said. The report projects 15.5 million miles (25 million kilometres) of new roads will be paved over nature between now and 2050, most in the developing world.

Many of the worst effects can be prevented by changing the way we grow food, produce energy, deal with climate change and dispose of waste, the report said. That involves concerted action by governments, companies and people.

Individuals can help with simple changes to the way they eat and use energy, said the co-chairman of the report, ecological scientist Josef Settele of the Helmholtz Center for Environmental Research in Germany. That doesn’t mean becoming a vegetarian or vegan, but balancing meat, vegetables and fruit, and walking and biking more, Watson said.

“We can actually feed all the coming billions of people without destroying another inch of nature,” Lovejoy said. Much of that can be done by eliminating food waste and being more efficient, he said.

Canada should not want to lead the world on climate change policy

Published on

From the Fraser Institute

By Ross McKitrick

Some commentators in the media want the the federal Conservatives to take a leadership position on climate, and by extension make Canada a world leader on the journey to the low-carbon uplands of the future. This would be a mistake for three reasons.

First, unlike other areas such as trade, defence or central banking, where diplomats aim for realistic solutions to identifiable problems, in the global climate policy world one’s bona fides are not established by actions but by willingness to recite the words of an increasingly absurd creed. Take, for example, United Nations Secretary General António Guterres’ fanatical rhetoric about the “global boiling crisis” and his call for a “death knell” for fossil fuels “before they destroy our planet.” In that world no credit is given for actually reducing emissions unless you first declare that climate change is an existential crisis, that we are (again, to quote Guterres) at the “tip of a tipping point” of “climate breakdown” and that “humanity has become a weapon of mass extinction.” Any attempt to speak sensibly on the issue is condemned as denialism, whereas any amount of hypocrisy from jet-setting politicians, global bureaucrats and celebrities is readily forgiven as long as they parrot the deranged climate crisis lingo.

The opposite is also true. Unwillingness to state absurdities means actual accomplishments count for nothing. Compare President Donald Trump, who pulled out of the Paris treaty and disparaged climate change as unimportant, to Prime Minister Justin Trudeau who embraced climate emergency rhetoric and dispatched ever-larger Canadian delegations to the annual greenhouse gabfests. In the climate policy world, that made Canada a hero and the United States a villain. Meanwhile, thanks in part to expansion of natural gas supplies under the Trump administration, from 2015 to 2019 U.S. energy-based CO2 emissions fell by 3 per cent even as primary energy consumption grew by 3 per cent. In Canada over the same period, CO2 emissions fell only 1 per cent despite energy consumption not increasing at all. But for the purpose of naming heroes and villains, no one cared about the outcome, only the verbiage. Likewise, climate zealots will not credit Conservatives for anything they achieve on the climate file unless they are first willing to repeat untrue alarmist nonsense, and probably not even then.

On climate change, Conservatives should resolve to speak sensibly and use mainstream science and economic analysis, but that means rejecting climate crisis rhetoric and costly “net zero” aspirations. Which leads to the second problem—climate advocates love to talk about “solutions” but their track record is 40 years of costly failure and massive waste. Here again leadership status is tied to one’s willingness to dump ever-larger amounts of taxpayer money into impractical schemes loaded with all the fashionable buzzwords. The story is always the same. We need to hurry and embrace this exciting economic opportunity, which for some reason the private sector won’t touch.

There are genuine benefits to pursuing practical sensible improvements in the way we make and use fossil fuels. But the current and foreseeable state of energy technology means CO2 mitigation steps will be smaller and much slower than was the case for other energy side-effects such as acid rain and particulates. It has nothing to do with lack of “political will;” it’s an unavoidable consequence of the underlying science, engineering and economics. In this context, leadership means being willing sometimes to do nothing when all the available options yield negative net benefits.

That leads to the third problem—opportunity cost. Aspiring to “climate leadership” means not fixing any of the pressing economic problems we currently face. Climate policy over the past four decades has proven to be very expensive, economically damaging and environmentally futile. The migration of energy-intensive industry to China and India is a very real phenomenon and more than offsets the tiny emission-reduction measures Canada and other western countries pursued under the Kyoto Protocol.

The next government should start by creating a new super-ministry of Energy, Resources and Climate where long-term thinking and planning can occur in a collaborative setting, not the current one where climate policy is positioned at odds with—and antagonistic towards—everything else. The environment ministry can then return its focus to air and water pollution management, species and habitat conservation, meteorological services and other traditional environmental functions. The climate team should prepare another national assessment but this time provide much more historical data to help Canadians understand long-term observed patterns of temperature and precipitation rather than focusing so much on model simulations of the distant future under implausible emission scenarios.

The government should also move to extinguish “climate liability,” a legal hook on which dozens of costly nuisance lawsuits are proliferating here and elsewhere. Canada should also use its influence in the UN Intergovernmental Panel on Climate Change to reverse the mission creep, clean out the policy advocacy crowd and get the focus back on core scientific assessments. And we should lead a push to move the annual “COPs”—Conferences of the Parties to the Rio treaty—to an online format, an initiative that would ground enough jumbo jets each year to delay the melting of the ice caps at least a century.

Finally, the new Ministry of Energy, Resources and Climate should work with the provinces to find one region or municipality willing to be a demonstration project on the feasibility of relying only on renewables for electricity. We keep hearing from enthusiasts that wind and solar are the cheapest and best options, while critics point to their intermittency and hidden costs. Surely there must be one town in Canada where the councillors, fresh from declaring a climate crisis and buying electric buses, would welcome the chance to, as it were, show leadership. We could fit them out with all the windmills and solar panels they want, then disconnect them from the grid and see how it goes. And if upon further reflection no one is willing to try it, that would also be useful information.

In the meantime, the federal Conservatives should aim merely to do some sensible things that yield tangible improvements on greenhouse gas emissions without wrecking the economy. Maybe one day that will be seen as real leadership.

Federal government’s environmental policies will do more harm than good

Published on

From the Fraser Institute

By Matthew Lau

The study covered grocery bags, food packaging, soft drink containers, furniture, t-shirts and other plastic products. In most cases, replacing plastics with alternatives causes greenhouse gas emissions to rise by 35 to 700 per cent.

Through a variety of regulatory and spending initiatives, the Trudeau government is expanding its control over our lives, often in the name of climate change or other environmental objectives. For example, the government plans to force consumers to buy electric vehicles instead of conventional cars and has proposed or implemented plastics restrictions on consumers and businesses—everything from plastic drinking straws and plastic utensils to clothing material and food packages.

However, while evidence of the high costs to consumers continues to mount, evidence of the environmental benefits is notably absent. Indeed, many recent studies provide evidence that Ottawa’s restrictions on consumers may well cause net environmental harm. One reason is that the plastic products the federal government is so intent on restricting are more environmentally efficient than alternatives.

study published earlier this year in the journal Environmental Science & Technology concludes, “15 of the 16 applications a plastic product incurs fewer greenhouse gas emissions than their alternatives.” The study covered grocery bags, food packaging, soft drink containers, furniture, t-shirts and other plastic products. In most cases, replacing plastics with alternatives causes greenhouse gas emissions to rise by 35 to 700 per cent.

Why? Because plastic generally takes less energy to manufacture and transport than the alternatives. In fact, many plastic products that are more environmentally friendly than non-plastic alternatives (according to the study) are products the Trudeau government wants to ban or curtail through regulation.

Other evidence shows plastic bans of the type imposed in Canada cause environmental ruin, contrary to the predictions of politicians. For example, research in New Jersey found after single-use plastic bags were banned in 2022, shoppers switched to the heavier reusable bags. “Owing to the larger carbon footprint of the heavier, non-woven polypropylene bags,” reported the Wall Street Journal, “greenhouse gas emissions rose 500%.”

Similarly, the New York Times reported that while California banned single-use plastic bags almost a decade ago, in 2023 “Californians threw away more plastic bags, by weight, than when the law first passed, according to figures from CalRecycle, California’s recycling agency.”

Also from the Wall Street Journal, analyses suggest electric vehicles often emit more particulate pollution (dust, dirt and soot) than conventional vehicles. That’s because most particulate pollution these days is not from the tailpipe but from tire wear. EVs are much heavier than conventional vehicles so their tires wear out faster, increasing particulate pollution. The firm Emissions Analytics compared a plug-in electric to a hybrid vehicle and found the plug-in electric, which weighed more, emitted about one-quarter more particulate matter than the hybrid as a result of tire wear.

Last year, the chair of the U.S. National Transportation Safety Board noted that EVs manufactured by Ford, Volvo and Toyota were all about 33 per cent heavier than conventionally powered versions of those same vehicles. That’s a problem not only for the environment but also for driver safety—and yet more evidence that the Trudeau government’s EV mandates will harm Canadians.

When it comes to vehicles, plastic products and many other things, the Trudeau government should begin reducing its control over consumers. The harm to consumers is evident; the compensating benefits to the environment—if any—are not.
