Many population- environment organizations concerned about human population impact on the planet believe they cannot talk about ‘coercive’ population policies, only education and good access to family planning. But are they falling into the same trap as environmental organizations that refuse to acknowledge the overriding evidence that our ever growing numbers are a key part of the problems we face?

Advocates for 20 proposals to mitigate climate change speak at Conference at Manchester Town Hall, UK, with a report on the ten best of the 20 to appear in Sunday's Guardian, UK on Monday 13 July.

How can we ever meet the needs of a rising number of people with growing energy demands, when fossil fuels are running out and population growth is undermining efforts to substitute green energy supplies for fossil fuels? Governments are planning massive expansion of nuclear power but it is no answer. Energy is a hugely complex issue. Brian McGavin tries to simplify the picture.

Month by month, immigration chaos at the UK Home Office reveals new depths of incompetence. After more than 11 years in power UK government claims that it is tackling the issues will do little to reassure a worried public. The safety valve of migration is part of our collective history, but large-scale migration now raises vital social, environmental and economic questions about where the world is going and how we deliver reform and a better life for people wherever they are born.

The United States, Australia and Canada have long seen themselves as lands of immigration with endless frontiers, but the space is getting crowded and the US has a major problem with illegal entry. Now Europe is facing similar challenges.

As we face the prospect of ecological meltdown due to the unprecedented demands of 6.5 billion humans on our diminishing natural resources, the United Nations assures us that the world can sustain 9.2 billion in 2050, after which it claims ‘demographic transition’ through rising living standards will lead to population stability and its eventual decline.
