A record number of countries voted to restrict fishing of mako sharks in an effort to protect the endangered species

A record number of countries have voted to protect the world’s fastest shark from extinction in a move welcomed by conservationists as a “wake up call” for fishing nations who have ignored the endangered species’ decline.

In Geneva this week, governments voted under the Convention on International Trade in Endangered Species (CITES) to regulate the international trade in both species of mako shark – long and short fin – in addition to 16 vulnerable species of sharks and rays.

This summer has brought a bounty of butterflies to the buddleias, but not the small tortoiseshell, which is in precipitous decline

Every summer, I read despairing messages about the absence of butterflies on buddleias. These observations fit my own experience.

The buddleias from my Norfolk childhood in the 80s and 90s reliably contained a dozen nymphalids – brightly-coloured small tortoiseshells, peacocks and red admirals.

Ian Duncan responds to letter on energy targets, Carol Blumenthal defends activists, Wendy Mulville recalls her experiences about air conditioning in Texas, Joseph Nicholas on the apocalypse, Michael Cook on forests, and world-class athletes step up

The letter on Wednesday (Clearer green energy targets are needed, 28 August) was quite right in recognising the UK’s lofty ambitions to become one of the cleanest and most innovative energy systems in the world on our path to becoming a net-zero emissions economy by 2050. But I take issue with the suggestion that our ambitions are not matched by our actions. We’re investing £274m to develop cheap, high-performance and durable batteries. We’re removing regulatory barriers to allow more storage facilities across the UK. We’re supporting small-scale localised energy generation through our smart export guarantee – continuing our world-leading support for the solar industry.

As members of the EU, we were obliged to implement the VAT increase for solar technology and storage. Once we leave, it may be possible to review this. All of this is supported by upgrades to the country’s energy infrastructure through our smart meter rollout and smart systems and flexibility plan. This enables homeowners to save money by putting them in control of their energy use, such as by charging electric vehicles or storing energy in a battery when it is cheapest.
