Acid rain over Britain has been all but eliminated 25 years after Margaret Thatcher launched a major bid to cut sulphur emissions, a study has found.
A new report on Britain's environment found that levels of sulphur in our atmosphere have dropped 90 per cent compared with their peak level in the 1950s, thanks to measures to control emissions from coal-fired power stations in the 1980s.
Now a similar political drive is needed to tackle the problem of nitrogen emissions from cars, power stations and farms and prevent the pollution from killing off wild flowers, experts said.
Having too much nitrogen in the atmosphere over-fertilises the Earth and allows grasses and weeds such as nettles to flourish, causing the disappearance of wild flowering plants.
The warning came in a new report led by the Centre for Ecology and Hydrology, which analysed how the chemical climate of the UK has changed in recent decades.
