With World Water Day, the United Nations will draw attention towards mankind’s water consumption, especially in industrial nations. Today, about 7 billion people live on our planet. The number is expected to grow by about 2 billion by the year 2050. Of course, each one of them will need water. That includes drinking water as well as water used in every day life, like for showering or food production. All together, that adds up to a lot of water. Just keep in mind, producing one kilo of beef consumes 15,000 liters of water, and one kilo of wheat guzzles up 1,500 liters.
The United Nations recommends a sustainable diet. That means we should be aware of how water-intensive products are. We also should reduce the amount of food we waste, says the UN. 30% of the food produced worldwide is thrown away. The water used to produce it is therefore lost forever. You can learn more about the World Water Day on the official UN website.  The latest Environmental Outlook report by the OECD also draws a bleak picture on rising sea levels that are swallowing cities and millions of people who will be suffering water shortages.
The UN also provides a very interesting FAQ about the value of water. Facts and figures about water can be found from the National Geographic.  If you are a U.S. resident, the National Geographic provides another interesting feature, a water footprint calculator to estimate your water use on a daily basis.

Juan Zacarias always carries a camera with him. He keeps his eyes open for the next great shot and is continuously taking pictures. I was glad to have him on board for shooting my report at a sewage plant in Nicaragua. Out of the blue we got a chance to take a helicopter flight over the area with the plant and the amazing lakes surrounding it. Juan was thrilled. The weather was great when we took off. The chopper took us over Lake Managua which is bigger than we imagined. Heading south-west, we flew along Rio Tipitatpa, where Lake Managua connects with Lake Nicaragua in what is the largest contiguous reservoir for drinking water in Central America. It could have been a perfect day, but as the flight progressed the wind got stronger. Too strong for some of us. Sick bags became very handy. Finally, with solid ground under our feet again, I thought to myself, that I liked the view very much – but next time I would definitely prefer a windless day.

If you live in a big city or even a megacity, in high apartement buildings, you are certainly aware, that these cities never have enough public green spaces. But there is help. If you need a green view to lift up your mood, or you just want to grow some tomatoes, than you will find the idea in the video above interesting. The Paris based designers Barre & Charbonnet have build a small garden-like construction, that you could use either way, inside or outside the rooms. The idea is to create a “micro-habitat” and to “reinterprete the hanging gardens”, the designers say on their homepage.  Besides: You will have always a green horizon.

The World Wind Energy Association (WWEA) has some good news for the world market for wind turbines. Not only that the market has recovered last year, it also set a new record: 42 gigawatt of new capacity had been installed in 2011, the worldwide total capacity rose up to 239 GW. According to the WWEA todays wind power would be enough to cover 3 % of the world’s electricity demand. China is the biggest player in the business, says the WWEA. The country installed around 18 GW of new wind turbines within 2011, coming to a total capacity of 63 GW – that’s more than one fourth of the global wind capacity. The second largest market for new wind turbines was again the USA, followed by India and Germany, which grew about 2 GW.
