The BBC reports restoring peat moors degraded by farming may prove a relatively inexpensive way of tackling climate change, a report shows.

Wet peat bogs store carbon that’s been sucked from the air by plants, but many bogs have been drained for farming. As drained peat dries, CO2 is produced – so in that sense peat’s causing a climate problem like cars, planes and factories. But statisticians say parts of the peat problem may be relatively cheap and easy to solve. They say the benefit of blocking up drainage ditches and bringing back vegetation to the moors shows benefits way higher than the cost.
