I agree that a four-day working week could have many benefits (Thousands of UK workers begin world’s biggest trial of four-day week, 6 June), but helping to mitigate the climate crisis is unlikely to be one of them, as people may well use their longer weekends to fly abroad, without the need to take any days off from work.

• Those of us who farm regeneratively do use fertilisers, we simply don’t use artificial ones (The regenerative farm working to improve soil without fertilisers, 3 June). There are lots more food producers like us – big and small – than is generally recognised. Local demand for our naturally grown produce is increasing all the time.

• Boris Johnson may be trying to drag us back to imperial units, but there is no need for the Guardian to help him out. The graphic with your report (UK to send long-range rocket artillery to Ukraine despite Russian threats, 6 June) tells us that the M31A1 rocket has an overall weight of 302kg, and contains an explosive warhead of 200lb. What’s wrong with 91kg?

• Isn’t the expression “working royals” something of an oxymoron (Queen’s absence strikes symbolic note as royals gather at jubilee service, 3 June)?

• I have just heard the news that Antony Gormley is to become a German citizen. Does this mean that those of us left in Britain will be officially Gormless?
