A simple virus in web can arise more public concerns of CO2 concentration in the atmosphere than PR department of UNEP, which spends a bunch of billion euros to sustain the project activities. Why not to spend the 1/100.000 of the money on good hackers. Just imagine opening the google tab and there is a board of statistic information of how we fucked up our environment and killing people, flora, fauna.
Opening a radio stream doesn't cost that much, but the regulations of FCC and all these burocracy issues makes the attempt in vain. Just imagine A sustainable radio FM 99.9
We go to Kneipe and buy a bier for 3-4 Euros. Just imagine a simple board in the pub, saying 1 Cent of it goes to renewable energy research efforts.
Why should we be so stupid not starting the big deals from little, obvious and clear things...
