This piece is disturbing because it reads like a press release that had to include a bit of journalism in it. There’s virtually no critical analysis of the danger of what’s happening. The only mention of the word “law” is a UN quote.

“The purpose behind the release of herbicide on the villages remains unclear.”

“The purpose behind the release of herbicide on the villages remains unclear.”

Israel has been dumping herbicides throughout southern Lebanon as part of a concerted ecocide campaign to render the region uninhabitable. This has been going on for months with Lebanese journalists & environmentalists regularly reporting on it.

The BBC: we don’t know why the Israelis are doing it

Tira de Laerte, em 4 quadrinhos.
1) Mulher, de costas, numa varanda. Ela está de camisola e segura na mão uma xícara com algo. Está espirrando com força, seus óculos até voam. Texto: “Hoje de manhã dei um bruta espirro.”
2) Mulher parada, olhando da varanda, segurando a xícara. Texto: “No mesmo instante veio, sei lá, uma tristeza.”
3) Mulher parada com a xícara. Texto: “Um desânimo imenso com o mundo e com a vida.”
4) Mulher dá um gole na xícara. Texto: “Teria relação com o espirro? - ou foi só o ensejo?”

Europe had its coldest January in 16 years. Historically, it would have been considered a warm January (pre-1990).

In 1922, insulin co-discoverer Frederick Banting refused to profit from the discovery and offered it to the world as a global public good.

Today, many people with diabetes still don't have access to affordable and quality treatment and care.

Brazil’s Massive Landless Workers’ Movement Leads the Way After 40 years of struggle, Brazil’s Landless Workers’ Movement, the world’s largest social movement, has rebranded its fight for agrarian reform around organic food production.

"At nearly two million members strong, the MST is now likely the world’s largest social movement, battle-hardened now after four decades, demanding agrarian reform."

The side plot is Bolsonaro, who loved the idea of torturing people, “planning” a massive prison break because the A/C is too loud and his TV sucks.

By “planning” I mean using the prison printer to print out the escape plans, chasing emus during outdoor recreation hours, etc.
