Canada’s assisted-dying law has expanded since 2016. What can England and Wales learn about safeguards, eligibility and social pressure?

Quand la peste a décimé la population mondiale, la biodiversité a, paradoxalement, elle aussi chuté

En analysant des archives polliniques, des chercheurs montrent que l’abandon des terres agricoles a fait reculer la diversité des plantes pendant plus d’un siècle.

Les prévisions relatives au changement climatique prennent souvent l’année 2100 comme point final. Mais il est important d’envisager ce qui se passera au-delà, au moins jusqu’à l’an 2500.

Climate change predictions often use the year 2100 as an end-point. But it’s important to consider what will happen beyond that, at least up to the year 2500.
