Thanks 'ed'... glad you like it! There is a think purple website now too.
There is something curiously childlike and beautiful about a 1 metre/yard diameter purple balloon... all my kids love them.... even my 15 year old son enjoys them... they move through the air with great grace... combination of their high mass and high 'air' resistance... they move in slow motion... oh and there is their exquisite perfect spherical shape...
if full of pure CO2 they would weigh exactly 1 kilogram... heavier than air...
my family's carbon footprint is 9 tonnes CO2 p.a (for 6 of us, primary footprint ie home energy and all travel including air) or 9000 kg
rather neatly, that's 1 'yardstick' balloon of CO2 - that my actions cause to be emitted - every hour... of every day... of every year.... not good (and i am trying hard - its better than some... and worse than others!)
when we imagine that load of balloons dumped into our rapidly shrinking air-fill space remaining - we may get a nasty jolt (the total available 'air fill' space remaining is roughly 20% to 40% of what we had 200 years ago - (ie it is 60 - 80% full now) based on 400 to 450 ppm upper limit CO2 levels. 200 years ago it was 300ppm
We are at 380ppm now, and rising at 2.5 ppm per year. At this rate we hit the lower 'full up level' in just 8 years. Some say we have exceeded it already.
If CO2 were purple we would have seen the sky change colour during our lifetimes. We would have taken action. But we are starting to see it now and we can get oursleves out of this mess as fast as we got ourselves into it - but only if we acknowledge the scale of the problem - the biggest issue of all time
in the history of humankind never before has something so invisible, unspoken, and by and large irrelevant moved centre stage so fast
each CO2 bubble we can avoid will be a drip in the ocean saved
Carbon will be the currency of the C21st (Dr Brenda Boardman, Oxford Univ)
the problem won't go away - until we start weighing it
the futures green - but only after we have done away with all the purple
