If economic growth undermines labour rights, tramples environmental safeguards and sidelines Indigenous communities, "We are setting ourselves up for long term problems in Ontario. That's not prosperity, it's a regulatory race to the bottom." - Shane Moffatt, Ontario Nature

Urban trees can lower temps by up to 12°C, but it’s not just about quantity. Species, layout and local climate all play a role in how effective they are. Strategic planting leads to cooler streets, cleaner air and healthier communities, especially in neighborhoods vulnerable to rising temperatures.
Trees are natural ACs for cities, if you plant the right ones
Urban trees are on the rise but researchers are only starting to uncover the best way to cool cities with them

It's common for some birds swallow small rocks, most likely to aid digestion by grinding food already in their stomachs. Here's a Merlin (Falco columbarius) getting caught in the act.

#ObservationOfTheDay
A brown raptor takes a stone in its beak. The bird begins to swallow the stone whole, its beak wide open. The bird turns and looks directly into the camera as if it knows it's been perceived.

We are deeply saddened by the passing of Dr. Jane Goodall — a trailblazer for women in science, a voice for animals, and a tireless champion for nature and conservation. Her legacy will continue to inspire generations to protect the living world we share. 💚 #JaneGoodall
