Sir – As a local resident worried about the impact of humankind on the environment, I went to Redbridge Recycling Centre this afternoon in the hope that I might, in my small way, contribute to making Oxford a greener place.

Once I had arrived and deposited a few household items into the bins, I was politely asked by one of the staff to leave the premises. The reason? I was a pedestrian and only cars are allowed.

Is this an example of the council giving to the environment with one hand and taking from it with the other?
