In the huge rubbish dump in the barrio of Cateura, on the south side of Asunción, Paraguayan youngsters who sort through the capital’s rubbish have found the means to make music. The orchestra known locally as Melodias de la Basura or Los Reciclados, and in English as the Landfill Harmonic, was started in 2006 by an environmentalist and music teacher, Flavio Chavez.

The home secretary last week criticised the ‘uncontrolled mass immigration’ that took place before 2010 for its effects on housing and public services. The latest census data show that half the population growth in the decade after 2001 was due to immigration. Theresa May is certainly right to say immigration affects housing demand, but the question is how much. According to May, ‘more than one third of all new housing demand in Britain is caused by immigration’. Nick Boles, a minister under pressure because of his plans to build on the countryside, told the Daily Mail that ‘100,000 new homes a year will be needed to accommodate’ migrants.

On Friday, thousands of protesters will converge on Fort Benning, Georgia, home to the Western Hemisphere Institute for Security Co-operation (WHINSEC). It’s had this title since 2001, but when it was set up in Panama in 1946 it was the School of the Americas. In 66 years it has trained 64,000 soldiers from Latin America in counterinsurgency, sniper warfare, interrogation techniques and other useful methods for repressing their citizens.

Three weeks ago a remarkable caravan of vehicles arrived at the Mexican town of Reynosa, just across the border from Hidalgo, Texas. It left the northern border of Nicaragua on 12 October, carrying the relatives of migrants who made the journey north to cross illegally into the United States, but vanished along the way. The caravan, which finished its journey through Central America this weekend, was trying to draw attention to their disappearance and – if possible – find them.

Yesterday we went into the red. According to the Global Footprint Network, between 1 January and 22 August mankind used up a year’s worth of the earth’s resources. Earth Overshoot Day came sooner this year than ever before. Ten years ago it fell on 3 October, and as recently as the 1970s we were still living within our means. Things are slipping fast.
