Qu: Cigarettes: the environmental impact…

Tuesday the 19th of August 2008

Qu: Having read your answer on the effect of patio heaters (last bastion of the smoker) on global warming I wondered what the effect of the 6 billion cigarettes smoked annually around the world has on the global environment?

Oh dear, this answer sure ‘ain’t pretty. Now I’m really going to have to disown all my still-fag-smoking now ex-mates. 

Let the anti-ciggie tirade begin! Starting at the end and working backwards seems appropriate as cigarettes are most obviously harmful to the environment when discarded, marring the view as they lie scattered beneath the fore mentioned patio heaters. 

Sadly, cigarette butts are most often than not thrown to the floor and left as litter.  It is estimated that over 4.5 trillion cigarette butts are irresponsibly disposed of annually, making them the most littered item in the world. 

There seems to be a general consensus (ask any smoker) that cigarettes are bio-degradable over a 25 year period– however this figure is debatable and some experts doubt that the filters will ever degrade. Even as they break down cigarettes are harmful as they release the 4,000 chemicals that they contain, contaminating the soil or rivers, lakes and ocean that they are washed into. Wildlife is also affected as these toxins enter the food chain and many creatures fatally consume the indigestible fibers. Cigarette packaging is often littered as well; in the UK alone, each day, 122 tonnes of cigarette related debris is thrown out.

As they are smoked they are an environmental nuisance, as 90% of their smoke gets into the atmosphere, adding to air pollution (remember the days that you couldn’t even see to the bar when you walked into your local) and having a negative impact on the health of anyone nearby. 

If you think all that is bad then wait till you hear about the environmental impact of cigarettes. It is estimated that up to 200 000 hectares, usually in the developing world, are cleared to make room for tobacco farming every year. The sensitive tobacco plants are then treated with a nasty cocktail of fertilizers, pesticides and herbicides to protect them from insects and disease. Tobacco farms are often by villages and, when the chemicals inevitably leak into the soil, they begin to poison the waterways, ecological systems, crops, and livestock in the surrounding communities.  Tobacco uses more nutrients than several other crops, and this quickly degrades the surrounding soil.  It is also believed that the toxic chemicals may indirectly cause the development of pesticide-resistant mosquitoes and flies.      

Living by a tobacco farm is no fun then, but this gets a whole lot worse if you’re unlucky enough to be one of the workers harvesting the plants. When the wet leaves are picked nicotine can be absorbed through the skin resulting in nicotine poisoning.  This ‘green tobacco sickness’ causes dizziness, nausea, vomiting and breathing difficulties and affects 41% of workers every season. 

On top of the land clearance for tobacco planting we must also take into account the trees that are felled to process the leaves and to produce the wrapping and packaging for cigarettes. Nearly one hectare of forest is needed to dry every hectare of tobacco meaning that over 600 million trees are destroyed annually for this purpose. On top of that six kilometers of paper is used per hour by the machines that roll and package cigarettes! 

And then there is tobacco’s contribution to world hunger. According to Dr Judith MacKay, Director of the Asian Consultancy on Tobacco Control in Hong Kong, tobacco’s “minor” use of land denies 10 to 20 million people of food. 

Anyone fancy popping out for a smoke? Didn’t think so!

Waste not want not…

Wednesday the 9th of July 2008

foodpricesOne of the key issues at the recent G8 summit was the global increase in the cost of food. As discussed previously, the rising price of staple foods has been linked to the increased cost of oil, which has caused land previously used for food crops to be turned over to crops for bio-fuels.

At the summit in Japan, the World Bank President Robert Zoellick highlighted the growing food shortage and urged the US and ‘rich countries’ in the EU to reform their bio-fuels policies and concentrate on food production. All well and good but it’s hard to believe all this talk is going do much to curb the rate at which your weekly shopping bill is creeping up, especially considering the frequency of missed G8 targets.

But we’re not as helpless as we imagine, the average consumer might not be able to dictate how farmers use their land but we can make sensible choices when it comes to dinner time. You’d think, with the increased prices, that people would be making an effort to make each meal count, but a recent survey estimates the average UK household throws away £8 of leftovers a week and each year in the UK as a whole wastes 4 million tonnes of food. People are spending about 9% of their income on food, with poorer households forking out up to 15% of theirs on staple foods such as milk, eggs and bread - foods that have been hit hardest by price increases in recent months.

This week Gordon Brown urged Britons to stop wasting food and to avoid making unnecessary purchases. But it’s not just the consumers who need to change their habits, the government might be more successful in reducing waste if they tackled supermarkets directly. The Liberal Democrats environment spokesman Steve Webb, blamed the governments “cosy” relationship with supermarkets for their failure to change policies which make it harder for householders to avoid food waste: “They refuse to stock small portions, which are essential for the growing number of one-person households, and offer too many buy-one-get-one-free deals on perishable goods.” Supermarkets also account for a large percentage of waste and throw away large quantities of edible food through poor stock management.

So, what can you do? Try planning your evening meals for the week and using up tins you’ve shoved to the back of the cupboard. Making extra in the evening means you take care of lunch the next day too - and this saves on energy, as you won’t be turning the cooker on again. Cooking for more people always works out more economically so offer to cook for your flatmates or friends and get them to return the favour another night. You can also try avoiding supermarkets; they might seem cheaper at first but in the long term it means smaller shops can’t survive or have to put their prices up further. If you do have to go to the supermarket write a list and stick to it - don’t be tempted by offers which will leave you with a fridge full of out of date food.

What’s that got to do with the price of rice?

Wednesday the 28th of May 2008

With diesel topping 120p per litre and a further 2p rise in fuel tax planned for the coming months, many companies reliant on road mobility are up in arms. Lorry drivers staged a protest this week, blocking the M4 from London to Cardiff. MP’s too have been protesting, against Alastair Darling’s proposed vehicle tax on older, inefficient models.

It seems that owning and running a car is only going to get more expensive - an additional household cost that is predicted to hit poorer families, long-distance commuters and SUV owners hardest.

But is it really such a bad thing? The government has pledged to reduce CO2 from cars by a third by 2030 and these price increases are a strong incentive for people to rethink their long-term reliance on cars and for companies to invest in energy efficient technologies.

That said, the situation is by no means an entirely positive one. Worryingly, the increase in fuel is a major contributor to a global food shortage, which is causing food price inflation to rocket.

“The food price rises are a result of record oil prices, US farmers switching out of cereals to grow biofuel crops, extreme weather and growing demand from countries India and China, the UN said yesterday.” (source).

A combination of increased oil and fuel prices paints a grim picture for the economy; now, more than ever, it’s time to rethink your habits, if only for the sake of your bank balance. Leave the car in the garage and jump on your bike for a start Got lots of heavy bags? Change of clothes? Gym kit? A laptop? No excuse - invest in some panniers and get pedaling. As for food prices - try planting some veges in your own garden - salad leaves like rocket and spinach can be expensive in those ready to wash packets from the supermarket but are surprisingly easy to grow - especially at this time of year. Buy locally produced food and be aware of what you use every week so you can avoid wastage. Easy!

To bee or not to bee…

Friday the 23rd of May 2008

Sorry - couldn’t resist! But seriously… the recent decline, due to Colony Collapse Disorder (CDD), in the world’s bee population is nothing to joke about. Bees play vital part in ensuring the global food harvests are successful through their role as pollinators. Without bees many crops would fail; a sobering thought considering the rise in demand for food due to an expanding population and the transfer of much crop production into biofuels.

beesThe mysterious disease attacks colonies quickly; over the course of a week the majority of the bees will desert the infected hive go off to die elsewhere. The US is worst effected with CCD recorded in at least 24 states and concerned British Beekeepers are lobbying DEFRA to fund research into finding a cure.

The most worrying thing is that because no-one seems to know what is causing CCD, there is no way of tackling it. There are many theories on the cause; one is that the bees may be suffering from stress as beekeepers increasingly transport them around the country to carry out pollination contracts in commercial orchards.

Some researchers blame the increase of mobile phone towers, which are said to inhibit the bees navigation systems. Others think that bees are suffering from a poor diet; the growing use of chemical herbicides and pesticides and the low nutritional value of GM crops could both be responsible. Global warming is also a factor as it accelerates the growth rates of pathogens like fungi, viruses and mites, which are known to damage colonies.

US scientists found that infected hives were shunned by other bees and insects, indicating that there was something toxic in the colony itself. They also found that the few bees left behind in the hive were carrying “a tremendous number of pathogens” virtually every known bee virus, as well as fungal infections, suggesting that the bees’ immune systems were being suppressed in some way. (source)

It’s also worth noting that organically raised bees, which are not subjected to genetically modified crops and chemicals, are not experiencing Colony Collapse Disorder.

Organic meat: a climate hazard?

Friday the 16th of May 2008

cow fartingRadio 4’s Tom Heap’s recent comments on the high impact of a carnivorous diet on the environment are not groundbreaking news. The UN has calculated that livestock warms the planet more than transport and for years The Vegetarian Society have campaigned to raise awareness about the damaging effect to the climate of eating meat.

Cows and sheep burp, fart and even breathe methane - a gas with about 20 times the global warming power than carbon dioxide! Their manure is also heavy with nitrates, which pollute both water and air. What’s more, livestock are relatively inefficient at turning food into protein so feeding them involves clearing acres of land for crop production, leaving less room for climate friendly forests.

Fearing their carbon-heavy practices will be penalized; the meat industry has found low GHG solutions indoors. Once caged, the animals’ diets can be strictly controlled, they don’t ‘waste’ energy by running around and their manure can be burnt as fuel avoiding damaging evaporation and seepage into rivers.?

Peter Bradnock of the British Poultry Council says: “Organic poultry meat has about 45% more global warming potential than indoor-reared poultry meat.”

So, why not eat your pork pie and avoid global warming? All well and good for you, but what about the animals? In ‘What About China?’, The Soil Association’s Robin Maynard points out that the practice of battery farming leads to disease, mutilation, injury and even cannibalism amongst the cramped and frustrated animals.

If you’re still secretly swayed by the climate argument for battery farming, get this: because factory farmed animals are at higher risk of disease they are routinely fed growth-promoters and antibiotics, a practice which has been identified as promoting the development of MRSA and other super-bugs. Over 30 years ago the Swann Committee warned the meat industry about the consequences of feeding animals the same drugs used on humans but unfortunately, this didn’t persuade the meat industry to change their ways. The full consequences of this decision are still emerging; in 2007 a new strain of MRSA was found in intensively farmed pigs and super-bugs are increasingly found in hospitals across the UK.
