There is no fuller spectrum of light than outdoors. Plants outside have the greatest range of effects. Leaving the same plants grown indoors, as rather monotonous, in the true sense of the word.
I have never heard such utter bollox as some of the comments here regarding the state of our planet. Of course it's getting warmer, only a child wouldn't of noticed. Yes the sea has risen, Look at it. China Russia and India are not the worst. They are more sustainable than the States or Canada. China is over 100% better. Only the oil producing zones of Qatar and the Arab Emirates are doing more harm, and oddly luxembourg, per capita. The idiots who don't want to act will always circulate such preposterous stories. Get your heads out your asses and look out the window. Turn off the TV, put down the papers, stop reading internet sites and just look out the fucking window. Stop acting like sheep and do some leading.
