I think that getting caught up in objections to housing development is a terrible diversion and a waste. Look up a housing estate on a map with satellite view and zoom out so you can compare it to the vast areas which are sprayed with pesticides, herbicides and chemical fertilisers and where grazing destroys biodiversity. All of the above is currently subsidised by taxpayers.
The scope for winning environmentally is enormous in the countryside but instead all the attention gets absorbed by residential planning where the impact is the smallest.
The government should be changing agricultural policy for the environment and wildlife, creating local & accessible nature reserves and forests for the politics and building houses for the people.
