The solution is surely to use the non-profit Ecosia search engine that plants trees and quite simply guarantees that it protects your data (Together we can thwart big tech’s data grab, Opinion, 7 January)?

• It is a daily joy to read such wonderfully detailed accounts of unchanging, centuries-old oak trees, rivers, animals, birds and fauna from around the UK in the country diary. Please keep them coming. They help us to maintain our sanity in these dark times.

• What a delight to see the photograph of the 1973 European Communities stamp (Letters, 10 January). But what struck me most was that the stamp cost only 3p. The current 2nd class rate is 58p, a 1,833% increase in 45 years. Just shows how postage costs have risen massively against wage rises.

• Surely Bath beats both Harlech and Dunedin with its steep streets (Report, 11 January)? Try struggling up Bennett Lane to reach Camden Road after work as I did in the 1960s and 70s – I’ve never been as fit since!

• My money would be on St Patrick’s Hill, Cork City, Ireland. The gradient is absolutely terrifying for drivers, like climbing the side of a house. What’s more, it’s a proper street with buildings and it ascends directly from the centre of the city.
