What connects a Pacific grey whale and you last visit to the shops?

What connects a Pacific grey whale and you last visit to the shops?
On your last visit to the shops, it is almost certain that you came home with some plastic that you hadn’t taken out with you: if you are really careless, then it would include the plastic carrier bags from the shops you visted, but it’s hard to avoid the odd polystyrene punnet in shrink wrap. Then there are the cardboard boxes with plastic wrappers on the food inside, and sometimes also on the outside!
Then there are those little bottles of water in shrink-wrapped multipacks, and packs of fruit drinks with tough wrappers that will be around long, long after the drink has been consumed and excreted into the sewage system.
Shrink-wrap can’t normally be recycled by local authorities, nor can polystyrene, nor many other packaging materials, so they end up in land fill or being burned in the incinerators that no-one likes in their back yard (so why do those same poeple continue to produce so much waste?), along with much of the recyclable plastic.
Some of it just gets chucked anywhere: just look at the verges of a major road that hasn’t been cleared by the local authority for a while. I have been picking up this sort of litter as I walk or run through parks and the countryside for decades, but what gets missed just blows somewhere. Today’s haul was a dirty nappy in Ashridge Forest, left just off the dirt footpath in a pretty piece of woodland. There was plastic in that too.
What has this to do with grey whales? Have a look at these web pages:
http://www.guardian.co.uk/environment/2010/jul/11/plastiki-rothschild-plastic-bottle-catamaran (millions of tonnes of plastic swilling around in the Pacific Ocean while sea life disappears)
http://www.huffingtonpost.com/2010/04/20/beached-grey-whale-in-sea_n_544130.html (A beached grey whale contains large amounts of domestic plastic.)
None of these materials existed 50 years ago, when plastics were still relatively expensive and the technology was at an early stage, so the entire phenomenon has built up during one generation. Our society is more obsessed with cleanliness and smelling nice than it ever was, but we seem to pay less and less attention to the filth and pollution that we leave in our wakes as we drive on through our lives.
It cannot make sense that every time we buy a sandwich, a drink and a coffee, which are consumed in 10 minutes, we throw away:
Sandwich: shrink wrap or plastic sleeve, carboard pocket, the bits we didn’t want to eat.
Drink: A clear plastic bottle with label and coloured plastic cap.
Coffee: Polystyrene or carboard cup, plastic top, plastic or wooden stirer, paper sugar packet.
What can you do about it? Quite a lot actually, but only if you are willing to think a bit more about your actions, and to not just take the most convenient course every time, which usually means buying everything in one trip to the supermarket: local shops and outdoor markets usually put less packaging on food items. And you can always select items that have less packaging, or tell the butcher that you don’t really need two plastic bags and plastic film around those chops.
If you are feeling really bold, you could protest to the retailer.
If you disagree with all of this and are one of those people who think that their convenience is paramount, and that chops need 3 layers of plastic, then you won’t have read this far anyway. But if you did read this far, I’d be interested to hear how you can justify it.
Climate Shenanegans and Does What Scientists Say Matter?
January 29, 2010 by Doug Kennedy
“What blooming weather: so much for global warming!” is a cry I have heard more than once as we suffer a cold winter.
Of course, weather and climate are different – we experience weather every day, and a year is a long time. Climate applies over tens, or hundreds of years and describes the general, overall situation. We find it difficult to see this perspective when battling through the snow of January 2010 or sweltering in the heat of June 1976. One degree centigrade is nothing within the variation of weather, whereas if a climate changes by a degree it is significant.
If the entire global average temperature goes up by one degree, it is a major change, and this is what is happening.
Climate scientists around the world have persuaded politicians that global warming is happenin. For some of those politicians, it is a disaster that is happening now as their countries are in danger of inundation from the sea already; most accept that global warming is caused by human activities but are having some difficulty in doing anything about it, but there are some who have not accepted it or who choose to ignore it as an issue. The overall status is that scientists think it is happening and have warned humanity that it needs to be dealt with.
A large minority of the UK and US populations do not accept that humans cause global warming, and recent revelations of wrong information in high level publications and nefarious emails among climate academics have given great impetus to the sceptics. There are few sceptics among the scientific community, but their voice tends to be magnified through the media by political and business interests, so these mistakes will have a resonance far beyond what is merited.
An interesting comparison the case of Dr Wakefield and his anti-MMR vaccine campaign. I heard yesterday that the General Medical Council roundly condemned him and his actions which caused thousands of mothers to withdraw their children from vaccination. The result has been increased levels of measles and mumps, which have killed and damaged children. I feel strongly about this as my sister’s immune system was permenantly damaged by measles in the 50s, before vaccines were available. Every study and enquiry into the matter has concluded the Wakefield was wrong, and it transpires that he had a conflict of interest anyway, but that hasn’t stopped the press and some people in vociforously promoting his cause. And this in spite of the damage the diseases are doing children today.
So my conclusion is that we believe what we choose to believe, and scientists can experiment till the sky falls in, but even if all of their conclusions point the same way, the public at large won’t necessarily accept them. We also tend to pick out the parts that suit our individual points of view, such snippets are often wielded like a large debating club, even if they are inaccurate, flawed or plain wrong.
BUT, we must accept that we have been warned that global warming is a threat that puts civilization and millions or billions of lives at risk within the coming century. If we just continue as normal and do nothing to alleviate the risk, how will future generations look upon us? If the outcome is disastrous, then our generation will be cursed and despised. If things don’t turn out so badly, then we will still have used up the great bulk of all of the oil and gas resources of the world in two generations, and be leaving a planet strewn with trash and pollution.
As a friend said to me the other day, ‘Perhaps I just don’t care that much.’
Global Warming is not the problem….
