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.

Turning to renewable energy sources is an effective way to tackle climate change, but does it damage our environment too? A lot of critics say biomass production exploits important land and offshore windparks disrupt the marine habitat.

The German government is trying to find a way to address the offshore windpark problem with a new solution: a sort of bubble-curtain. The problem is, construction in the Baltic Sea produces a lot of noise underwater, and that creates problems for whales and poropoises that use sonar signals for communication. So officials are proposing a type of low-cost technology that would release bubbles from the sea floor and mute a lot of the noise. That way, the drilling and pounding wouldn’t be quite so disruptive and marine life could continue communicating as they do now. If it’s successful, the bubble-curtain idea could be used on several other underwater construction sites!
