Nanonuisance? Nanotechnology could revolutionise our lives, but some people are concerned by the darker undercurrents.
Some people believe a future planet full of microscopic machines and microscopic agents in food or packaging could be a good thing. Nanobots might save countless lives in surgery, nanopackaging could make food cheaper and last longer, feeding millions.
But like any new technology, there may be risks. According to Wikipedia, ‘nanotech’, is the study of the controlling of matter on an atomic and molecular scale. Generally nanotechnology deals with structures of the size 100 nanometres or smaller in at least one dimension, and involves developing materials or devices within that size.’

Does man-made global warming actually exist?
by Julian Caldecott
Humans are (ecologically speaking) a 'weed' species, the toughest vertebate predator and coloniser that ever evolved in this world. Once we learned how to prevent or cure most infectious diseases, and how to use the energy in fossil fuels, an explosion in our numbers and impact became inevitable. True to our nature, and now armed with numbers and machines, we have been aggressively burning, ploughing, ranching, trawling, mining, logging and polluting local ecosystems.

Base Europe's electricity on solar plus other renewables, not nuclear
If we are to phase out fossil fuels and avoid nuclear, we must find some very large new sources of electricity - even more so if we want to replace some of the oil used in transport with electricity.
One of the few such sources is the DESERTEC project to bring solar energy from N Africa to Europe: it's now a $400bn project led by a German consortium. DESERTEC is actually much more than this - it's a complete electricity plan for Europe with low loss transmission lines linking different types of renewables, wind, hydro, biomass and it phases out nuclear. There is a great FAQ page about it here: http://www.desertec.org/en/concept/faq/ which answers most of the concerns people raise.
Capitalism: A Love Story
Capitalism: A Love Story is a 2009 American documentary film directed, written and starring Michael Moore. The film centers on the financial crisis of 2007–2010 and the recovery stimulus, while putting forward an indictment of the current economic order in the United States and capitalism in general. Topics covered include Wall Street's "casino mentality", for-profit prisons, Goldman Sachs' influence in Washington, DC, the poverty-level of many airline pilots, the large wave of home foreclosures, and the consequences of "runaway greed". The film also features a religious component where Moore examines whether or not capitalism is a sin and if Jesus would be a capitalist.
