You forgot breeding
"Whenever an eco-activist starts going on about gadgets or electricity or food, ignore them. The big stuff is travel, making and having things (ie buildings, furniture, tools, interior decor, infrastructure etc) and heating/cooling (a large amount of this is laundry and personal hygiene)."
my partner and i have decided not to have children, thereby limiting the amount of co2/waste/what ever that v2.0 would of used. yet i get called "selfish" and accused of being a planet killer because i refuse to buy green things (because a new green tv is so much more efficient then sticking with an old one that works fine, no sunk in carbon in manufacture nope) and plan on buying a car that does 15-20 mpg(a 1990's era car at that, so again no sunk carbon in making new). Not to mention horror of horrors closing the curtains in my office room and using a light bulb (not much light from outside+ fully visible to street)
the point? the people calling me this often had 2+ children (more usually 3) that they each then kit out with the latest consumer crap/fashion(which changes every 6 months) and cart around in such wonderfully environmental cars as prius and MPV. We are probably more green then most "greenie" couples (no kids) due to not buying the latest whizz bang and buying things we like not what is new (i have some 15 year old clothes i wear with brand new for example)
With the world already overcrowded is it not the "think of the children" brigade with there spawn making the situation worse? after all if they have more then 2 children they are increasing the strain on the precious globe. nah its gadgets, Jeremy Clarkson and not enough windmills
Fun things to do at a middle class dinner party:
1) bring up the above,
2) mention how organic food (which your host/ess will almost certainly go on about as if it was made from gold) can feed 4 billion people, wait until they go "so what" before telling them the population of earth is around 7 billionish
