Trump's [cabinet] appointments reflect what I call the Pollution Paradox. The more polluting a company is, the more money it must spend on politics t… - George Monbiot

[P]erhaps the most pernicious innovation was to shut down crucial legal defences. One attorney general removed the defence of proportionality; another removed the defence of lawful excuse. This means that environmental activists can no longer explain their motives to a jury. They have to be tried as though they were mindless vandals, inconveniencing people for kicks, rather than seeking to prevent, at great cost to themselves, the greatest crisis humankind has ever faced. Some protesters have sought to explain themselves regardless, and have as a result been imprisoned for contempt of court.

People in eastern Congo are massacred to facilitate smart phone upgrades of ever diminishing marginal utility. Forests are felled to make “personalised heart shaped wooden cheese board sets”. Rivers are poisoned to manufacture talking fish. This is pathological consumption: a world-consuming epidemic of collective madness, rendered so normal by advertising and the media that we scarcely notice what has happened to us.

If you travel to Worth Matravers - the chocolate-box village in Dorset in which 60% of the houses are owned by ghosts - you will not find hordes of homeless people camping on the pavements in cardboard boxes. The market does not work like that. Young people from the village, unable to buy locally, have moved away, and contributed to the housing pressure somewhere else. The impacts of the ghost market might be invisible to the purchasers, but this does not mean they aren't real. Second-home owners are perhaps the most selfish people in the United Kingdom.
In England and Wales there are 250,000 second homes. In England there are 221,000 people classed as single homeless or living in hostels or temporary accommodation. (These desperate cases comprise about 24% of those in need of social housing.) I am not arguing that if every underused house were turned back into a home the problem of acute homelessness would be solved. I am arguing that homelessness has been exacerbated by the government's failure to ensure that houses are used for living in.
