Red squirrels, for whose troubles the greys are blamed, became virtually extinct in the UK before greys were even introduced, writes Natalia Doran

Your article (The faddy eater: Could I stomach southern-fried squirrel?, 22 February) should be admired for its honesty in showing appropriate discomfort with the idea of eating a creature that should have been living, breathing, playing, instead of suffering an early violent death. However, it also propagates a couple of myths regarding the highly intelligent and successful grey squirrel. The thing is, red squirrels, for whose troubles the greys are blamed, became virtually extinct in this country before greys were even introduced. That happened because of habitat loss. The reds were then also reintroduced from continental Europe, so the “nativeness” narrative is flawed. The tree damage is hugely exaggerated as well – the Forestry Commission puts the damage at 5%. More is lost due to poor growing practices. Furthermore, that figure relates to commercial forestry: in natural woodland grey squirrels are uniformly good for the ecosystem.

Major step taken by government Multi-Sector Commission following 15 year process

Two “naked” people spotted hunting armadillo. One “naked” family on a river-bank. About five other “naked” people - plus houses, settlements and crops - seen from small planes. Fresh footprints on a path, on a tree trunk, and along a Canadian oil company’s seismic lines. Noises in the night. Whistling and birdsong imitation. A loosed arrow. Fishing utensils, abandoned fires, and food stolen from inhabitants in the surrounding areas. . .

This is just some of the vital evidence currently being used to promote the establishment of two new reserves for indigenous peoples living in “isolation” that together could extend for more than 2.5 million hectares across one of the remotest parts of Peru’s Amazon, along the border with Brazil. If created, they could become the biggest indigenous reserves in the country.

Why are scientists worried about freezing temperatures in winter, is the beast from the east a freak event – and what is the polar vortex?

Q: Snow in winter. That feels reassuringly normal. Does this mean the climate has fixed itself?

A: Unfortunately not. In fact, many scientists are concerned this is a prelude to more extreme and less predictable weather.

Analysis from EU’s scientific risk assessors finds neonicotinoids pose a serious danger to all bees, making total field ban highly likely

The world’s most widely used insecticides pose a serious danger to both honeybees and wild bees, according to a major new assessment from the European Union’s scientific risk assessors.

The conclusion, based on analysis of more than 1,500 studies, makes it highly likely that the neonicotinoid pesticides will be banned from all fields across the EU when nations vote on the issue next month.
