“Dutch people cycle an average of 2.6km each per day. If this pattern was replicated worldwide, annual carbon emissions would drop by 686 million tonnes. This mammoth figure exceeds the entire carbon footprint of most countries, including the UK, Canada, Saudi Arabia and Australia.” @euronews.com

Cycling like the Dutch would slash the world’s carbon footprint
If everybody cycled like the Dutch, we could offset the UK or Australia’s entire carbon footprint.

As a doctor, I say this: before we even consider assisted dying, fix how we care for the most vulnerable | Zubir Ahmed
A person’s wish to die can be shaped by whether they have access to proper palliative care – and too many do not, says Labour MP and transplant surgeon Zubir Ahmed

In the footer, it notes the data sources, indicating that the information is based on media mentions from Media Cloud (2025) and death data from the US CDC (2025) and the Global Terrorism Index, with a clarification that values are normalized to sum to 100%.

Climate crisis
Sarah Benn loses suspension appeal
The retired GP and climate activist Sarah Benn (below) lost her High Court appeal against a misconduct finding and suspension by a medical practitioners' tribunal over her protest actions. Benn was suspended from the medical register for five months after defying an injunction three times during protests and was sentenced to 32 days in prison. She argued that the climate situation was so desperate that lawful means were

insufficient to achieve change.
But the court held that she was not entitled to rely on being a member of the medical profession while repeatedly defying a court order, which resulted in imprisonment.
