After 15 years of warnings, the EU has now launched legal proceedings against the UK for failing to reduce "excessive" levels of nitrogen dioxide (NO2) air pollution - mostly diesel particulates from traffic fumes. The government has pushed back its own targets to cut emissions and is showing little will to prioritise the issue.
We know that trees reduce pollution levels by as much as 30%
... and have reported here on innovative and inexpensive ways in which tree canopies help to capture and remove these dangerous pollutants from our air, and the scientist who has recently published on the subject will be joining us via Skype on Saturday 26th April to talk about her work (see April 2014 Conference tab above).
Let's keep planting and replacing trees so that we can all breathe more easily.
