Here's something that's not talked about enough

The air pollution from burning fossil fuels kills an estimated 10 million people a year

1 in 6 deaths is caused by fossil fuels

These deaths could are avoidable.

Switching to renewables would save these lives.

We are faced with a choice, save lives or kill people.

As a society we need to actively choose to do the right thing.

DOn't worry about the environmental damage of a few few flights by SpaceX's Starship - they will only be for the ruling elite.
The same ruling elite that by their actions around the world are already bringing us to our knees economically and fighting any transition actions to save our ecosystem.

Rishi Sunak is as rich as the King. But in 2022, he paid the same tax rate as *a nurse*.

Our tax system is broken.

Right now, multimillionaires like Sunak hoard wealth, while 1/3 kids grow up in poverty. Enough.

We're forcing a reckoning.

Syria's worst drought in decades pushes millions to the brink The drought has slashed wheat harvests by 40% in a country where nearly 90% of the population already lives in poverty.

'rainfall has dropped by nearly 70%, crippling 75% of Syria's rain-fed farmland

Here’s what you need to know about Starmer’s illiberal protest curbs: they would have killed the Labour party at birth | George Monbiot The rights we enjoy in the UK, and the movement the PM purports to lead, were built on protest. Those rights are in dire peril, says Guardian columnist George Monbiot

To be effective, protest must be noisy, obstructive, annoying. No longer is this allowed. Now the last attribute of effective dissent – persistence – is also to be banned. But the moment protest ceases to be effective is the moment democracy dies. www.theguardian.com/commentisfre...

Antifa again terrorizing the community with music, smiles, and civic joy. Imagine the horror of people being fed from gardens, reading in libraries, honoring MLK, and driving Subarus. Civilization clearly hanging by a thread of decency.

PM Carney once called climate change β€œthe most pressing issue of our time.” So why then is his government fast-tracking fossil fuel projects that turbo-charge these types of climate disasters? Our latest blog warns that this approach puts Canada’s climate goals and our communities' health at risk.

The surging price tag of wildfires, in one chart Wildfires are getting worse β€” and a lot more expensive for the rest of us.

Wildfires aren’t just getting bigger. They’re getting massively more expensive.

A new study shows the most destructive fires are happening more often, fueled by climate change, urban sprawl, and decades of fire suppression.
