One positive effect of the coronavirus pandemic has been on the environment. It’s led to the biggest ever reduction in the volume of carbon dioxide released into the world’s atmosphere.
At the height of the lockdown scientists say that daily emissions around the world dropped by almost a fifth. The biggest fall was in China, while in the UK carbon dioxide output was reduced by 13 per cent. But scientists are warning that the cuts in greenhouse gases are likely to be temporary.
Meanwhile in the United States, President Trump has been strongly criticised by health experts, after stating that he was taking an anti-malarial drug to protect himself against coronavirus. Regulators have warned there’s no evidence that hydroxychloroquine provides any protection from Covid-19 and say it can cause heart problems.
