Woodland Trust’s competition comes as charity campaigns for more robust legal protection for precious trees

An oak tree shaped like an elephant and the oak with the widest girth in the UK have been shortlisted for the annual Tree of the Year competition.

The Woodland Trust runs the annual competition to raise awareness of the UK’s ancient and at-risk trees.

Sharing increasingly crowded spaces could result in greater risk of pandemics, human and animal conflicts and loss of nature, say researchers

Over the next 50 years, people will push further into wildlife habitats across more than half the land on Earth, scientists have found, threatening biodiversity and increasing the chance of future pandemics.

Humans have already transformed or occupied between 70% and 75% of the world’s land. Research published in Science Advances on Wednesday found the overlap between human and wildlife populations is expected to increase across 57% of the Earth’s land by 2070, driven by human population growth.

Beef, lamb and dairy products are the most carbon-intensive foods by far. More boldness around dietary changes is needed

The publication of a major study linking habitual eating of processed and red meat to a greater risk of type 2 diabetes is the latest very good reason to think hard about what we consume. Rising obesity rates, food poverty and concerns about the seemingly unstoppable rise of ultra-processed and junk food mean British eating habits are a longstanding source of widespread concern. Many people also recognise that there are environmental reasons to change their diets. Meat and dairy are the most carbon-intensive foods by far. Most of us should eat less of them. But the messaging around this continues to be poor.

Ever since red and processed meat was linked to an increased risk of cancer a decade ago, people have been advised to limit their daily consumption of these to a maximum of 70g. But while the “five a day” fruit and vegetables campaign turns 21 this year, and warnings about excess sugar abound, other government guidelines on food remain vague. While they specify two weekly portions of fish, one of which should be oily, about meat they say only “eat some”. There are no recommendations as to how much white meat should be consumed.

Extreme heat affecting nearly 23m people across US south-west and pushing Texas’s electrical grid to the limit

A heat dome covering the US’s south-west region is affecting nearly 23 million Americans, bringing with it some of the highest temperatures of the summer and putting pressure on the electrical grid in Texas.

The heat dome phenomenon occurs when strong, high pressure traps hot air over a region, preventing cool air from traveling in and causing temperatures to rise on the ground and stay high.

Marsh restorations allowing populations of fen raft spider, which can be up to 7cm long, to recover

One of the rarest and largest species of spider in the UK is said to be making a comeback on nature reserves.

After facing near extinction over the last century, the UK’s population of fen raft spiders is steadily increasing, and numbers are at a record high this year, according to the conservation charity RSPB.

Industry and NGOs backed the UK government’s proposal to maintain the gross emissions cap if greenhouse gas removals (GGRs) are included in the UK ETS, and argued their inclusion could incentivise their uptake but additional support will still be needed, according to responses to a government consultation.
