Everywhere we look environmentalists are being exposed as hypocrites. But is this relevant to the arguments these environmentalists are making and, if not, how can we improve the quality of public debate on environmental issues?Read More »Mr Broccoli Versus Piers Morgan: Hypocrisy and Environmental Action
The idea of using a meat tax to improve human health and protect the environment has been getting a fair amount of attention from prominent scientists in the media. Professor Mike Rayner was quoted last year as saying, “I would like to see a tax on red meat and meat products. We need incentives to cut down on meat and dairy consumption.” Marco Springmann told the Guardian, “Current levels of meat consumption are not healthy or sustainable. The costs associated with each of those impacts could approach the trillions in the future. Taxing meat could be a first and important step.” And Joseph Poore suggested that taxing meat will likely be necessary to avoid serious environmental problems.
Taxing food products to promote human health is controversial. It has been suggested that introducing taxes to limit particular food consumption behaviors is a troubling shift towards a “nanny state,” involves paternalistically imposing “alien values” on people, and interferes with the free market by picking and choosing winners and losers among different products. A decision to impose a dedicated tax specifically targeting meat would need to adequately address all of these concerns.Read More »Should Meat Be Excluded From the UK’s Value Added Tax?

Last year, the first truly novel synthetic life form was created. The Minimal Cell created by the Venter Lab, contains the smallest genome of any known independent organism.[1] While the first synthetic microbe was created in 2010, that was simply a like for like synthetic copy of the genome of an existing bacterium. Nothing like the Minimal Cell exists in nature.
This great advance in synthetic biology comes at a time where natural life forms are being manipulated in ways never seen before. The CRISPR gene editing system has been used to create hulk-like dogs, malaria proof mosquitoes, drought resistant wheat and hornless cows. The list of CRISPR-altered animals grows by the month.Read More »Synthetic life and biodiversity

The man who called global warming a fabrication invented by the Chinese to make US manufacturing less competitive is now president-elect of the US. His followers expect him to withdraw the US from the Paris climate change agreement and eliminate the environmental regulations introduced by his predecessor.
But recently, Donald Trump has shown a few signs that he might be open to being convinced that climate change is a real problem requiring action. In discussion with journalists at the New York Times, he expressed the view that there is “some connectivity” between human activity and climate change, adding that he’s keeping an open mind about it.Read More »Cross Post: Our political beliefs predict how we feel about climate change

Environmental epigenetics is a rising field of scientific research that has been receiving much attention. It explores how exposure to various physical and social environments (e.g. pollution or social adversity) affects gene expression and, eventually, our health. Environmental epigenetics can sometimes explain why some of us carry increased risks of developing specific diseases. It provides activists a powerful vocabulary to promote environmental awareness and social justice. This new vocabulary, which allows us to discuss the consequences of disparities at the molecular level, has been enthusiastically mobilized as an effective way of stimulating political will for promoting public health preventive strategies.Read More »Guest Post: Epigenetics: Barriers to the translation of scientific knowledge into public policies

Why do we think that climate sceptics are irrational? A major reason is that almost none of them have any genuine expertise in climate science (most have no scientific expertise at all), yet they’re confident that they know better than the scientists. Science is hard. Seeing patterns in noisy data requires statistical expertise, for instance. Climate data is very noisy: we shouldn’t rely on common sense to analyse it. We are instead forced to use the assessment of experts.Read More »Cross Post: What do sugar and climate change have in common? Misplaced scepticism of the science
This week is ‘Sustainable Fish Week’ at Ghent University in Belgium. All fish on the university restaurants’ menus come from sustainable fisheries or fish farms (with practices that can be maintained without reducing the ability of the target fish to maintain its population and without threatening other species within the ecosystem, for example, by removing their food source, accidentally catching and killing them, or damaging their habitat). Tuna sandwiches will be taken off the menu and a sustainable alternative will be provided instead. Those who take their meal at a university restaurant will receive a free ‘fish guide’ with helpful information for making responsible fish choices at home. Those with strong stomachs may also enjoy the opportunity to taste jellyfish at the university restaurants. The message is that, if we continue to eat unsustainable fish, then soon jellyfish will be the only alternative to fish left on the menu.
The lord of the manor is not a typical peasant, and doesn’t have the same responsibilities. Nowadays, it is quite fashionable to see humans as part of the natural world, part of a cycle of life, dependent on a nature that could eradicate us in an instant if it chose to. The truth is far less comforting.… Read More »We ARE lords of the planet – that’s the problem
The world is full of problems. Pollution is a problem. The destruction of the coral reefs, the eradication of the rain forests, the mass extinction of animal species are problems, and tragedies. Loss of biodiversity is a problem. Global warming is a problem. Poverty and the unequal distribution of resources are major problems.
But lack of basic resources isn’t a problem. We’ll have enough food, water and energy for the whole human race for the forseable future, at reasonable costs. Take a worse-case scenario for all three areas, and let’s look at the figures.
When is a little dioxin too much dioxin?
Dioxin is a persistent organic pollutant (POP) that accumulates in the food chain and is highly toxic to living systems. The Stockholm Convention on Persistent Organic Pollutants commits signatories to ‘reduce or where feasible, eliminate the production and environmental release’ of dioxin.
So we know that dioxin is not a good thing to be releasing into the environment. And we also know that particular human activities, such as the smelting process that produces certain metals and chlorine bleaching of wood pulp in the paper industry produce dioxin. The question is when is it ‘feasible’ to eliminate the production and environmental release of dioxin?Read More »Pulp Friction in Tasmania: when is a little dioxin to much dioxin?
