I wonder how many lawns will be mown over this Easter weekend? |
I think someone at your local wildlife trust has been hitting the wrong buttons on their calculator. Certainly there is a problem but for some more realistic figures and solutions see:
Grass Cutting Beats Driving in Making Air Pollution ENS 31may01
The very extreme figures seem related to 'old' and potentially poorly maintained mower engines, it is also important to note that the pollution figures relate to PAH, not to the whole range of emissions - SOx, NOx, CO2 etc. Still there is clearly a need for a debate about how gardens can be best maintained; getting rid of lawns also brings problems - see Wildlife Gardening forum !
