The Now Show on BBC Radio 4 (a comedy show based on current affairs) mocked the UK Governments' attempt to account for the services that the biosphere provides us with in financial terms. I wish they hadn't. We can't continue to liquidate natural capital and call it income, therefore some attempt to cost (say) the pollination service performed by bees, or the various services provided by trees should theoretically go some way to correcting our current system's tendency to ignore 'externalities' and plnder the planet for profit.
The UK's Conservative government (in coalition with Liberal Democrats) could live up to its Conservative name by seeking to find ways to conserve our planet, and focus less on conserving institutions and traditions for their own sake. The need to sustain human life on this planet is very serious. Yes, make humour about it, but be careful not to undermine any effort in that direction.
