Seeds of change The Chelsea Flower Show opened in autumn for the first time, delayed thanks to the pandemic. The show has been cancelled before due to the world wars — during the second world war the site was used for an anti-aircraft gun emplacement. But it wasn’t always held in Chelsea. It began as the Royal Horticultural Society show in Chiswick, held from 1827 onwards. It moved to Kensington Gardens in 1861 when rival flower shows were attracting visitors away. In 1888 it moved to Temple Gardens, between Fleet Street and the Thames. It was first held in Chelsea — in a single marquee — in 1913. Highly charged Energy prices spiked. Which countries have the most expensive electricity for domestic customers (US cents per kWh)?

Late in 2013, David Cameron snapped. ‘Get rid of all the green crap,’ the then prime minister told energy ministers. His demand came after a backbench revolt over the surcharges tacked on to household energy bills to support onshore wind power. Not for the last time, his decision was based on a spectacular failure to see one of the big trends of the age: the stunning fall in the costs of renewable energy that was already under way. In the past decade, the cost of generating electricity from onshore wind has fallen by 40 per cent. For offshore turbines, it’s down almost a third. Globally, it’s now generally cheaper to construct and run new renewable generation than it is to build a new station to burn fossil fuels.

We are being urged — and, in some cases, paid — by the government to plant more trees. Actually, this happens most years. I can even remember ‘Plant a tree in ’73. Plant one more in ’74’. It is a bit like saying ‘Have more babies’, without any provision for their care once born. It all depends which trees, where you plant them and how you tend them. If you walk through the country nowadays, or near new-build housing estates where trees have been planted in ‘mitigation’, you will see large numbers of saplings dead or dying, still in their tree guards, planted too close together and then forgotten. New trees need protection from rabbits, deer, weeds and competition.

Positive thinking The government wants us to test ourselves for Covid-19 twice a week, using lateral flow kits which will be freely distributed. What is the risk of being ordered to self-isolate as a result of a false negative? — While the NHS claims that these tests produce false positives in 0.1% or fewer cases, an evaluation by Porton Down and Oxford University last year found a false positive rate of 0.3% in a hospital setting, rising to 0.39% in the community — in other words, about one in every 256 tests. — According to the Office for National Statistics infection survey, in the week to 27 March one in every 370 people were infected (not necessarily showing symptoms) — 0.27% of the population.

Paradise lost Sir: After reading Jonathan Beswick (‘Critical mass’, 16 January) I am writing to express the shame I feel as a lifetime member of the Church of England at our Church’s attitude to this pandemic. Here was the greatest opportunity in 70 years to demonstrate care for our fellow people, to advertise our faith and love and to keep the Church in the public eye. I hoped that there would be thousands of Church members flocking to help the lonely and the isolated. But I find my local church locked. This was the chance for the Church to show commitment and sacrifice for the good of the community, to cast aside timidity and get on with normal life, as does the postman, the milkman, the parcel delivery brigade, the health service and many others.

Lockdown damage Sir: I am sick and tired of people taking the moral high ground and looking down on ‘lockdown sceptics’ like me as if we don’t care. It’s ironic, because while there is no clear evidence to date that national lockdowns actually save more lives (contra the interview with Matt Hancock, 9 January), there is plenty of evidence that lockdowns ruin lives. If anyone should take the moral high ground it is those, like myself, who witness this ‘collateral damage’ on a daily basis. Yes, the health issues are complex. And who would want to govern at this time?
