ZCBlog: A response to John Hayes’ comments on wind power

CAT disagrees with John Hayes’ recent comments on the development of wind power in the UK.

As a long industrialised nation, the UK should be doing more than the minimum required to meet its targets. We should be pioneering a shift toward renewable resources, which we can continue to rely on in centuries to come – unlike rapidly dwindling fossil fuels. Wind – which the UK has an enviable abundance of – remains an integral part of that shift.

The Centre for Alternative Technology’s Zero Carbon Britain report shows how we can harvest a substantial share of our energy from wind power. The proposed use of on-shore wind power is much smaller to that of off-shore wind but we do believe that the benefits of on-shore wind farms has yet to yield their maximum potential. Wind power is an established energy source with a proven track record, the UK has significant wind power resources and therefore it should be cornerstone of our energy policy.

We believe that the next stage in the development of on-shore wind should be to increase local benefits by developing structures for increased local investment, to enable developments to share a much higher proportion of the returns with local communities.

Where’s the impact of pads and tampons?

 

In this series, we’ve been investigating the impacts of various different consumer products, attempting to untangle the complicated webs of production, manufacture and resource use. We’ve told the story of a chocolate Easter egg, a cotton t-shirt, and a paperback book, discovering along the way some fascinating facts about how these products affect our increasingly fragile planet.

This week, we’re going to investigate menstrual products. Unfortunately, however you term them – sanitary products, menstrual products, whatever – it sounds euphemistic; there’s still a culture of shame surrounding the whole experience of menstruation. Leaving aside the awkwardness, however, and the nomenclature, our use – and disposal – of tampons and pads has a considerable effect on the environment. Every year, we discard an average of 200,000 tonnes of waste from menstrual products, a large proportion of which is destined for landfill or the ocean.

In this post, we’ll take a closer look at what tampons and pads are made of, and consider some alternatives. Help us tell the story by leaving comments below!


First off, let’s have a look at tampons. It’s estimated that one woman will use 11,000 tampons in her lifetime, or 22 items for each period. Each tampon is also estimated to take an average six months to break down, so it’s hardly a surprise that a 2010 survey found that for every kilometre of coastline, there were 8.9 tampon applicators (as well as 22.5 pads, liners and backing strips).

The tampon was first developed in the 20s and 30s, around the same time as the re-usable menstrual cup. However, a business model predicated on disposability was much more attractive, and tampons were marketed aggressively, fixating on their supposed hygiene and convenience. However, they’ve long been linked to health problems, most notably Toxic Shock Syndrome.

Made of cotton or a blend of cotton and rayon, a synthetic product made from wood pulp, there are also concerns that tampons could contain dioxins from the bleaching process and pesticides from the cultivation of the cotton. As we discovered in our post about the impact of a cotton t-shirt, cotton production makes heavy use of incredibly dangerous pesticides.

Tampons aren’t classed as medical products, and as such, don’t have to provide detailed product information. The Women’s Environment Network, in their informative report Seeing Red: Sanitary Protection and the Environment explain that tampon manufacture is self-policed by an industry-led body, which doesn’t even require that tampons be sterile.

This lack of information is especially concerning for fragrance-laced tampons, a concept which seems singularly bizarre. As the Campaign for Safe Cosmetics notes, “because the formulas are considered trade secrets, companies don’t have to disclose what’s in fragrance. We know from product-testing that fragrance may contain allergens, sensitizers, phthalates (a class of chemicals that has been linked to hormone disruption, which can affect development and fertility), neurotoxins and synthetic musks (which can also disrupt hormones).”


Disposable pads are a less modern invention than tampons, with the first versions hitting the market in the late 19th Century. Since then, they’ve evolved into something more user-friendly – as examples in the Museum of Menstruation show, earlier iterations required women to wear a belt to hold the pad in place.

However, the modern materials affording such convenience derive from the petroleum industry – therefore, their manufacture takes a dangerous toll on the environment. Pads also take a very long time to break down, leaving a long-term environmental legacy.


Every year, WEN report, the disposables industry spends a whopping £14 million advertising these products to us. The message – that, as WEN put it, “women are somehow dirty and in need of special cleansing products” – reaches 18.6 million women. So it’s hardly a surprise that disposable menstrual products seem necessary, even unavoidable.

However, there are other options. If you’re the crafting type, you can easily find patterns to make your own re-usable pads online. If not, re-usable pads are available to buy online, as well as re-usable menstrual cups.


What are the impacts of the things we buy? Where is the energy used? What are the impacts on other people and the environment?

Where’s the Impact? is an innovative teaching resource exploring the ecological footprint of products. There are literally thousands of processes involved in the production of any given product – to raise awareness about the impacts of production, pupils use a set of cards to tell the story of a product from beginning to end.

Become a long term volunteer at CAT

 

CAT is on the look out for a new bunch of fresh faces to volunteer from March til September 2012. Annually, CAT accepts two intakes of volunteers on six month placements, where they work closely their chosen department and become a part of the CAT community.

We asked some of CAT’s volunteers about their experience of being here; see below for their stories. For more information about becoming a long-term volunteer, follow this link.

Katie was a volunteer in the summer months in the gardens. With a horticultural background, she came to CAT to build on skills she already had and to develop confidence in her abilities as a gardener. During her time working in the gardens, Katie spent two days a week on the display gardens, and three days a week on the produce gardens. Her work helped produce food for the restaurant and staff lunches, as well as maintain the gardens on the visitor’s circuit which educate visitors to CAT about organic growing methods.

Being a part of the CAT community has been important to Katie. As she says, “it’s a hub of interesting people and projects, which is inspiring to be around.” Katie was also a member of site community, the group of CAT staff and volunteers who live on the CAT site, and enjoyed the communal lifestyle, sharing food and resources.

Making the most of the summer months, Katie and the other summer volunteers spent time exploring the surrounding areas. “To be able to live in a UNESCO biosphere is incredible!” Living so close to incredible surroundings of biosphere and nearby Snowdonia national park has been life-changing for Katie, who is staying on to create a series of films about bugs.

 

 

Amy is two months into volunteering in education, as well as Zero Carbon Britain. Having just finished a phD in chemistry, Amy was tiring of research and wanted to do something different. While she felt that she had a fairly good knowledge of sustainability issues, she wanted to learn more about the practical side of things. Visiting CAT with a university group in June, Amy was inspired by the atmosphere and feel of the site, as well as the pioneering research project Zero Carbon Britain 2030.

Her tasks as Zero Carbon Britain volunteer sees her write the regular newsletter, as well as give presentations to a variety of different groups. As an education volunteer, she’s currently attending workshops, with a view to leading them herself soon, and doing research that the other educators can use in their work. As Amy says, “no day is the same!”

Enjoying the ample natural beauty around CAT has seen Amy cycle around the nearby estuary, as well as climb a few mountains. Amy’s also enjoyed the social life at CAT, which sees volunteers and staff eat lunch each day together in the much-loved T Chest.

As for the future, Amy’s stint in the education department has already confirmed her interest in moving into environmental education. She says “I’ve really enjoyed thinking about communicating ideas to a range of audiences, not just schools. At CAT, you talk to a group of 10-year-olds one day, and a group of uni students the next.”

Martin has been volunteering in the information department for two months. Having worked for the Green Party, and having previously volunteered with Friends of the Earth and Transport 2000, Martin has long had an interest in sustainability issues. A member of CAT for several years, Martin decided to take a break from his work as a university administrator to deepen his knowledge.

So far, volunteering with information has seen Martin learn more about specific subjects, revise some of the public materials CAT provides, and edit and write web information pages. In the next few months, Martin is hoping to do some video editing. Information, says Martin, is a good position for those who “want to know everything about everything, people with overactive minds!”

Attracted to the area, Martin has always wanted to experience living in a rural community. It is, Martin notes, rather different from living in a city; it’s great “if you want time to think.” Welsh also interests Martin: “the fact that there’s another British language spoken here attracts me to the area; I like hearing the bilingual announcements when I get off the train in Newport.”

The Sex Life of Spiders

Spiders have a really roundabout way of getting on with the task of procreation– male spiders have two modified appendages called pedipalps on the front of their heads which are used to transfer sperm to the female, but unfortunately they produce sperm from the other end of their bodies which means that they have to disappear into a corner and concentrate on the job in hand so to speak and then transfer it to their palps. Then charged up and ready to go they venture out in search of a female. Courtship is fraught with danger for the generally much smaller male and spiders have developed an extraordinary range of techniques to ensure successful mating. The Nursery web spider wraps up a juicy insect in silk and presents it to his spouse and while she is busy unwrapping and eating it he gets on with what he’s come for. Some spiders practice bondage and tie the compliant female down with silken strands before getting on with it.Yet another species attracts a likely female by impressing her with a lively display of break dancing while others serenade their chosen lady with a tune by rubbing their legs together (stridulation). Perhaps most incredible of all some spiders put their spouses in a form of chastity belt after mating to ensure it is only their genes which are passed on–it’s thought that they leave part of their pedipalp which breaks off and forms a plug which means she cannot be mated, but also means that the male has now effectively castrated himself and is no longer of any use in continuing the line. It now makes sound practical sense to donate his body to the female giving her sustenance and converting him into eggs. So there you go—the humble spider has a lot more up its sleeve than it seems.

It’s Spring?… well the birds seem to think so

Mid February and we arrive to a veritable cornucopia of birdsong…

A Song Thrush, Mistle Thrush, Great Tit and the chaffinches were all in full song among the trees and rafters that they call home around CAT, accompanied by the cheerful song of the Robin.

The Song Thrush was really giving everything it had to be the strongest in the choir, but the tinge of sadness in the Mistle Thrushes song still came through, only to be cheered up by the jolly  Robin. The song of Spring has begun, and it promises to become ever more beautiful as the season continues.

The Great Tit sure it is Spring
The Great Tit sure it is Spring

So open the windows or step outside and let the birdsong wake you and convince you of an early spring. The birdfeeders at CAT have started to attract lots of attention from these feathered friends, and hopefully yours will do the same.

Bird Watch

Every day when we arrive at CAT,  a new email lies waiting for us telling us about birds,  plants and flowers  slowly creeping out of their winter slumber. Rennie Telford is one of CAT’s expert bird watchers and as Spring fast approaches we want to share with you some of Rennies insights into the wonderful world of nature.

Last week Rennie spotted around 10 or 12 crossbills in the topmost branches of some conifers.  When there is a shortage of pine cones in certain areas there occurs what is known as an irruption as large flocks of crossbills  fly great distances and invade localities which are heavily forested with conifers, so they might be around again. It is an unusual enough sighting as crossbills have never been seen at CAT.

Rennie writes……..

Alright , I know it’s freezing cold and frosty, but spring is on the way – trust me.  The early morning bird song around site is increasing daily, with more and more different species starting up. This morning we had both the Mistle Thrush and the Song Thrush blasting away from the trees. For those non-naturalists amongst you, a good rule of thumb to differentiate between the two is that the Mistle tends to sing from an elevated and exposed position at the top of the tree whilst the Song generally favours singing lower down and somewhat more concealed. Also the Song is smaller and more round shaped and of course the song is completely different— or it was – my earsight’s not what it used to be!

Sometimes we tend to overlook the more common birds because they are always there, but they can be just as, if not more, interesting than the unusual ones. Take the ubiquitous robin – there are several pairs on site and although they can be endearingly tame and confident around humans, they are aggressive little buggers to each other. They are extremely territorial and each pair has their own area which they defend robustly against other robins. The edges of these areas tend to overlap and this is where fairly evenly matched skirmishes occur – but when, say, T chest area birds penetrate deep into Cabins area birds’ territory (for a prime food source perhaps) – then the Cabins birds will attack quite viciously and generally dominate the invaders. When the situation is reversed, the T chest birds wiil usually come out on top. So the next time you pause to listen to the melodic outpourings of a cute little red breasted robin perched on a branch in the weak spring sunshine — remember the song translated is probably ” F*** off out of my manor innit, or I’ll have you”

Back to Robins. If you want to try and identify birds from their song ( which opens up a whole new world ) , the robin , at this time of the year is an ideal bird to start with. As the trees are bare of foliage it is easy to see a robin perched on a branch singing its lovely , liquid, warbling song. Once you have seen it, close your eyes for a couple of minutes and concentrate hard on the song — get it firmly in your head and then listen out for it over the next few days. After a while you will find that you recognise this particular song, even when there is a veritable cacophony  of other bird song around. Then progress to other easily recognisable birds – blackbirds, chaffinchs, blue tits etc. and repeat the process –locate, identify, close your eyes, remember it and listen out for just that song for a few days. You will soon build up a mental library of bird song that will last you a lifetime.
Thinking about it , it is probably best to do this when there are no visitors around — the sight of CAT staff standing around with their eyes shut, listening dreamily to bird song doesn’t really tie in with the image we wish to present of  a dynamic, highly motivated, perfectly honed, all action and totally professional workforce.  Which of course we are (??)
It is a really good skill to master — I am not particularly good at it (exposure to AC/DC and Seasick Steve at maximum decibels has not helped matters either ) but if you are interested, sign up for the woodland birds thingy this Saturday  ( see Grace ) and the dawn chorus walk which Grace is organising with a really brilliant lady from the RSPB is unmissable.

22nd February

If you are walking or cycling up the south drive listen out for a sharp, staccato drumming sound in the distance. This is the Greater Spotted Woodpecker talking to other woodpeckers by performing its drumming routine. It finds a suitable tree and proceeds to bash it repeatedly with its beak producing a far carrying and resonant sound which has a peculiar sort of vetriloquism to it and is very difficult to locate accurately. There are at least two pairs of these strikingly exotic looking birds in or around the quarry, they regularly visit the Cabins’ bird feeders and they were also regulars on the feeders at the back of the shop outside the Courses office.
There is something really manic about these birds — after all any bird that decides to repeatedly head butt a tree has got to be a bit loopy –they even have a sort of built in shock asorber at the base of the beak to avoid brain damage. This head banging analogy was re inforced to me a couple of years ago when I was listening to a slowed down recording of the drumming while trying to count the rate at which it struck the tree ( I know— I really should get out more ) and it sounded for all the world like the riff from Smoke on the Water!

These heavy metal head bangers of the avian world , also have a rather gruesome side to them and will enlarge the holes in nest boxes, of other species to get at the eggs and  nestlings inside , to provide a high protein supplement for their own brood  — which is why it is a good idea to reinforce the area around the entrance with metal or thicker wood and of course never put a perch below the hole.
