The accelerating loss of biodiversity poses a "fundamental threat" to the "survival of humankind," warned the head of the United Nations new biodiversity body, as he also sounded the alarm on the declining biodiversity on farms.

Zakri Abdul Hamid, founding chair of the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES), made the comments at the 7th Trondheim Conference in Norway on Monday.

On the widely noted declining plant and animal biodiversity in the wild, Zakri said “we are hurtling towards irreversible environmental tipping points that, once passed, would reduce the ability of ecosystems to provide essential goods and services to humankind.”

But biodiversity loss is hitting farms also, said Zakri, threatening the world's food supplies, both in terms of livestock as well as crops.

“The good news is the rate of decline is dropping but the latest data classify 22% of domesticated breeds at risk of extinction.”

Zakri cites incentives for more uniform breeds from industrialized countries as a contributing factor in the decline of livestock diversity.

“Those genetics are irreplaceable. Once they’re gone they’re gone,” Jeannette Beranger, research and technical programs manager at the American Livestock Breeds Conservancy,said.

Crops have suffered a loss of 75 percent of genetic diversity in the last century as locally-adapted varieties were abandoned in favor of genetically uniform varieties.

Take apples, says John Torgrimson, executive director of Seed Savers Exchange, an organization that saves and shares heirloom seeds.

Nowadays, you'll generally find only about 10 varieties of apples in markets, he says, and some of those are related to each other.

And the ubiquitous red delicious of today looks "tremendously different" from the red delicious of 100 years ago, Torgrimson says.

Yet "at one time, we had 20,000 varieties of apples in the U.S." In 2000, we had about 4,000 varieties, but most of those were held in private orchards across the country; market forces are bringing only a handful of varieties to consumers, says Torgrimson.

Further, noted Zakri, out of the 30,000 edible plant species only 30 crops account for 95% of human food energy, with the bulk coming from rice, wheat, maize, millet and sorghum.

We need genetic diversity, Zakri said, because it is key to providing "a large genetic pool that enables organisms to withstand and adapt to new conditions.”

Not to be overlooked in this declining farm biodiversity is the role of agribusiness, says Christopher Cook, journalist and author of Diet for a Dead Planet: Big Business and the Coming Food Crisis.

This "high-profile focus on recapturing biodiversity and repairing ecosystems" from the UN body is good, he says, but moving forward, "it's critical that they examine the central role that large-scale industrial agriculture and agri-food corporations have played in eroding our biodiversity and undermining ecosystems."

"In their relentless push for market control these corporations, Monsanto, Syngenta and others, often with help from governments, have monopolized and privatized our seed supply—and promoted monoculture farming that has destroyed soils and fed climate change and drought," says Cook. "Biodiversity and economic diversity are linked—to restore both, we must combat agri-food corporations' phenomenal economic and political power."

The work of bringing various stakeholders together to address the issue of biodiversity loss and genetic erosion is vital," adds Tanya Kerssen, research coordinator with Food First, an organization that works to eliminate the injustices that cause hunger.

And, echoing Cook, she says that "hopefully, the new platform will take seriously the role that industrial 'green revolution' agriculture has played in generating this crisis, which is being perpetuated at a breakneck pace through the corporate rush on land, water and other resources around the world.

If you want to see biodiversity loss in motion, just look at where a land grab has taken place.

"These 'land grabs' are transforming diverse, community-based food systems—which also rely on the diversity of nature, including wild plants, forests, pollinators, etc.—into monocultures dependent on corporate inputs. Conserving biodiversity requires empowering farmers, peasants and indigenous peoples to manage diversity in sustainable ways," says Kerssen.

The answer to this declining biodiversity will not be found in corporate agriculture, which started the problem, she emphasizes.

"The danger is that agribusiness will influence the process, or coopt the results, to assert itself as the solution to the problem it created—for instance, by making Monsanto’s claim that it can 'produce more, conserve more,'" cautions Kerssen.

"Another danger is that this process leads to the privatization of biodiversity—another market-based pseudo-solution—that will only increase speculative pressure by investors on the world’s most precious resources."

"Either way," says Kerssen, "it will be incumbent on social movements around the world to make sure IPBES recommendations are implemented with an eye towards justice and sustainability, not corporate profit."

Only with political will can we avoid the worst of climate change

It's fitting that the latest Intergovernmental Panel on Climate Change report was released during Earth Month. After all, the third chapter of its Fifth Assessment focuses on ways to keep our planet healthy and livable by warding off extreme climatic shifts and weather events caused by escalating atmospheric carbon.

Doing so will require substantially reducing greenhouse gas emissions — 40 to 70 per cent by 2050 and to near-zero by the end of the century. We must also protect carbon 'sinks' such as forests and wetlands and find ways to store or bury carbon. The good news is that weaning ourselves off fossil fuels, conserving energy and shifting to cleaner sources comes with economic and quality-of-life benefits.

"There is a clear message from science: To avoid dangerous interference with the climate system, we need to move away from business as usual," said economist Ottmar Edenhofer, co-chair of Working Group III, which produced the chapter.

Doing nothing isn't an option. That would lead to a significant increase in global average temperatures and extreme weather-related events such as storms, droughts and floods, wreaking havoc on our food systems, communities and the natural environment we depend on for our health and survival. Technological measures and behavioural change could limit global mean temperatures to less than 2 C above pre-industrial levels, but only with "major institutional and technological change."

Because we've stalled so long, thanks largely to deceptive campaigns run by a small but powerful group of entrenched fossil fuel industry interests and the intransigence of some short-sighted governments, we must also consider ways to adapt to climate change that's already occurring and that we can't stop.

Although carbon emissions are rising faster than efforts to curtail them, there are glimmers of hope. A growing number of networks — including cities, states, regions and even markets — are working together to implement climate plans. And costs of renewable energy, such as solar and wind, are falling so quickly that large-scale deployment is practical. Putting a price on greenhouse gas emissions through carbon taxes or other methods is one critical way to shift investment from fossil fuels to renewables.

Carbon-intensive fossil fuel economies will suffer as renewable energy technologies mature — especially those relying heavily on coal and unconventional oil such as bitumen from tar sands. Canada's choice: take advantage of the growing worldwide demand for clean energy technology, transit infrastructure and sustainable building techniques or continue to focus on selling our non-renewable resources at bargain-basement prices until climate and food-system destabilization swamps global markets and the world rejects Canada's high-carbon fuels.

The IPCC found responsibly addressing climate change by pricing carbon and making needed investments is affordable: ambitious mitigation would reduce economic growth by just .06 per cent a year. That's not taking into account the many economic benefits of reducing climate change — from less spending on health and disease to reduced traffic congestion and increased activity in the clean-energy sector. Considering the costs and losses climate change and extreme weather impose on our cities, communities and food systems, we can't afford not to act.

A clean energy revolution is already underway and, as the world comes to grips with the need to change, it will inevitably spread. As Canadians, we can choose to join or remain stuck in the past. Tackling global warming will require all nations to get on board. That's because greenhouse gases accumulate and spill over national boundaries. And, according to the IPCC, "International cooperation can play a constructive role in the development, diffusion and transfer of knowledge and environmentally sound technologies."

As a policy-neutral scientific and socioeconomic organization, the IPCC doesn't make specific recommendations, but it reviews the available science and spells out in clear, albeit technical, terms that if we fail to act, the costs and losses to our homes, food systems and human security will only get worse.

It's been seven years since the fourth assessment report in 2007. We can't wait another seven to resolve this crisis. As nations gear up to for the 21st climate summit in Paris in late 2015, where the world's governments have pledged to reach a universal legal climate agreement, international co-operation is needed more than ever. Let's urge our government to play a constructive role in this critical process.

Published on May 27, 2013
Earth had a climate long before we showed up and started noticing it and it's influenced by a whole series of cycles that have been churning along for hundreds of millions of years. In most cases those cycles will continue long after we're gone. A look at the history of climate change on Earth can give us some much needed perspective on our current climate dilemma because the surprising truth is, what we're experiencing now is different than anything this planet has encountered before. So, let's take a stroll down Climate History Lane and see if we can find some answers to a question that's been bugging Hank a lot lately - just how much hot water are we in?
