Sir, – The problem for the environment (and by extension, us) is that green parties exist. There should be no green parties, in Ireland or elsewhere in Europe. All political parties should be green and should have their green policies and intentions declared. The existence of green parties allows other political parties to point the finger at them while they themselves dodge or play down difficult environmental issues. – Yours, etc,
PATRICK BYRNE,
Killiney,
Co Dublin.
