Whether you think that those who threw orange powder paint at Stonehenge (Report, 19 June) should be jailed, or are worried about the continuing use of oil, it would be useful to remember that in 1964 the monument was “repaired” using concrete. Yes, it’s lovely to look at, but get a grip! The paint will wash off. The damage that continued use of fossil fuels will do to our world is irreparable.

• It is true to say that “the idea [of storing grain] is not that radical (Economist suggests storing grain to prepare for next global emergency, 20 June). Joseph suggested to the Pharaoh that he store grain at times of plenty to feed the people during a famine more than 3,000 years ago (as described in Genesis).
