The world overshoot day – are we consuming 1,5 planets a year?

I suppose it is common knowledge these days to remind ourselves that today is the day when “humanity has exhausted nature’s budget for the year.” In other words humanity spends earth’s annual biocapacity’s worth of resources in only a bit over eight months. Moreover, the time required to reach this point takes less and less time each year.

When you look at the below graph it is difficult to disagree with such musings. (more…)

Why economic growth is important for sustainability?

My brother visited South Korea some years ago. He brought me a plastic toy diver (below) that worked with a pair of AA-batteries.

We seriously couldn’t come up with anything better to do than build diving action figures? I admit though, that it was funny to imagine (in a self-loathing way) what the people working in the toy-diver-factory thought of the world around them and about the people buying the pointless things in the first place.
