Reasons to be positive. The economic downturn could be the catalyst for positive change. It should be translated into the wake-up call we need for a major change in aspirations and lifestyles to save humanity from the ecological and economic disaster that would otherwise result from continuing on the high carbon and resource depleting path we have been pursuing

It is environmental illiteracy and a complete lack of forward thinking to ignore the need to halt and then reverse population growth in the context of climate change, travel congestion, unaffordable housing, and resource depletion

Is it better that we manage population growth responsibly or should we to wait for nature to cull our numbers?

The UK still has time to accelerate the take-up of renewable energy and put the nation on a path towards clean energy that is cheaper, stable and more sustainable. We have a stark choice: We can stay stuck in the last century's boom and bust approach to our economy in the way we consume energy and resources, or create a sustainable, stable and renewable energy infrastructure with the long term environmental and employment benefits that ensue

Large carbon and resource savings arising from efficiency and renewable energy programmes will be completely cancelled out by the added resource needs of even small population increases. Action is urgently required on both fronts to protect our life on earth

What will use more finite resources? That 3rd or 4th child you have or driving a large car? We all need to think about the choices we make
