Why think small? Find out which of the Millennium Development Goals are lacking behind on schedule (my gosh, 2 years and 2 months left until 2015!). Then try to give one of those goals a big boost! Invent your own creative and fun solution to this particular global challenge, and 'test' this on a tiny scale, here or elsewhere. October 17 2012

Be a Plant-Eater for one month. No meat, no dairy products. Google/YouTube on 'PlantenEter' and you will get inspiration. You will do good for your own health as well as the health of the planet and mankind. Chance that you will continue after one month is rather big. Making it a good investment into a new and better lifestyle. October 14 2012
