Eating green may not be green

GOOD BUT GREEN? Scientists have long advised people to switch to a plant-based diet to benefit the environment but that may not be borne out by research.

A nutritious diet that includes lots of fruits and vegetables might not be the greenest in its environmental impact, according to a new study.

After analysing the eating habits of about 2,000 French adults, and the greenhouse gas emissions generated by producing the plants, fish, meat, fowl and other ingredients, researchers concluded that widely embraced goals for the health of people and for the health of the planet are not necessarily perfectly compatible.

Growing fruit and vegetables doesn’t produce as much greenhouse gas as raising cattle or livestock, the study confirms, but people who eat a primarily plant-based diet make up for that by eating more of those foods.

“When you eat healthy, you have to eat a lot of food that has a low content of energy. You have to eat a lot of fruits and vegetables,” said Nicole Darmon, the study’s senior author from the National Research Institute of Agronomy in Marseille, France.

Greenhouse gases – which include carbon dioxide, methane and nitrous oxide – are produced by machines that burn fossil fuels. That gas is then released into the atmosphere, where it contributes to climate change.

Food production – including the use of farming equipment and transportation – is estimated to be responsible for 15 per cent to 30 per cent of greenhouse gas emissions in developed countries, the authors write in The American Journal of Clinical Nutrition.

Scientists have long advised people to switch to a plant-based diet to benefit the environment and their own health.

To more closely examine that premise, Darmon and her colleagues used food diaries from 1,918 French adults to compare the nutritional quality of people’s real-world diets and how much greenhouse gas they produced.

Did Dinosaurs Fart?

Dinosaur gases ‘warmed the Earth’

Apatosaurus, formerly known as Brontosaurus, produced a lot of wind

 

Giant dinosaurs could have warmed the planet with their flatulence, say researchers.

British scientists have calculated the methane output of sauropods, including the species known as Brontosaurus.

By scaling up the digestive wind of cows, they estimate that the population of dinosaurs – as a whole – produced 520 million tonnes of gas annually.

They suggest the gas could have been a key factor in the warm climate 150 million years ago.

Canada condemned at home and abroad for pulling out of Kyoto treaty

China calls Canada’s decision ‘preposterous’, while Greenpeace says the country is protecting polluters instead of people

Canada has been condemned at home and abroad as “irresponsible” and “reckless” for pulling out of the Kyoto climate treaty, just a day after committing to a future legally binding deal at a major UN climate summit.

“I regret Canada’s withdrawal and am surprised over its timing,” said the UN climate chief Christiana Figueres. “Canada has a moral obligation to itself and future generations to lead in the global effort.” China, which agreed for the first time to legal limits on its emissions at the summit in Durban, denounced Canada’s decision as “preposterous” in its state media and called it “an excuse to shirk responsibility” in tackling global warming.

The domestic reaction was equally fierce with the announcement by Canada’s environment minister, Peter Kent, described as “shameful” and “a total abdication of our responsibilities”. Under the Kyoto protocol, Canada was committed to cutting its greenhouse gas emissions by 6% by 2012, compared to its 1990 levels. But its actual emissions have risen by over 30%, making failure inevitable. Canada’s inaction was blamed by some on its desire to protect the lucrative but highly polluting exploitation of tar sands, the second biggest oil reserve in the world.

Kent claimed that Canada would have to pay billions to meet its Kyoto target in 2012: “To meet the targets would be the equivalent of … the transfer of CAN$14bn [£8.7bn] from Canadian taxpayers to other countries – the equivalent of $1,600 from every Canadian family – with no impact on emissions or the environment.” He was referring to the cost of buying carbon emission permits (AAUs) from other countries to compensate for Canada’s huge overshooting of its target.

Opinion:

Canada simply wants to have its cake and eat it too. It doesn’t matter whose toes you tread on in business.

Canada made a promise, signed the Kyoto agreement, it should be held binding.
