Figures I've seen suggest that a cd disc is 5 times less environmentally friendly than streaming the same album. This does not include packaging and transportation etc.
The same LP is around 17 times less friendly.
However, people now stream music more than the discs bought in the past, which does not help to the streaming figures.
Numbers quoted are indicative and should be taken with a decent amount of sodium-chloride!!
Any human activity can be viewed as a threat to the world's ecology. I've done environmental conservation courses and done a bit of field work, so I'm a bit of an ecowarrior, to be honest. The thing is, all our collective contributions to the early demise and death of this planet are significant and are a direct cause of the negative impact, but I'm a realist. I'm not prepared to go back to living in a cave and abandon my biological right to my place in a modern society, using electricity and ranting on this forum. I do consider my carbon footprint, but my attempts to minimise the effects are completely negated by the lifestyles of my neighbours, never mind the new coal fired power station China builds every week. You can't obsess about this stuff and reduce your rightful quality of life in a modern world. Yes, try to recycle and don't burn tyres at the weekend, but just be sensible and practical about it. The thing is, humans will be gone in around 1000 years, because of war, disease, overpopulation and just plain old stupidity and I can guarantee the planet will eventually rid itself of any sign of our endless greed and destruction and our attempts to ruin the planet will prove futile. The planet will repair itself in the long term and another species, not obsessed with materialism and vanity will take our place. The world will give a big sigh of relief and the stage will be set for another life form to fill the hole we leave behind. 'Humans, thank **** they've gone. Time for another ice age and a bit of peace and quiet.' Sorry it's a bit off topic, but unless 8 billion people change their lifestyle and put the world first, nothing will change. Sean Lock accurately approximated a single person's efforts to minimse their impact, to be the same as turning up to an earthquake zone with a pan and brush. If you want to cut out all your daily activity to 'save the planet' then go ahead, but it won't change the outcome.
