She writes: BC’s own source revenue—taxes, fees & royalties—has plummeted from 19.2% to 15.4% of GDP over 25 years. This drop represents $16.8 billion in foregone revenues annually."
Tax cuts drive the deficit; progressive tax ⬆️ needed 👇

BC folks! Outstanding piece here by @iglikaivanova.bsky.social, co-ED of @bcpolicy.bsky.social.
BC has a revenue problem, not a spending problem
The solution to BC’s fiscal challenges isn’t spending cuts. Instead, BC needs progressive revenue measures.

Opinion: B.C. has a revenue problem, not a spending problem
Experience from early 2000s shows that underfunding public services and failing to address poverty leads to higher economic and social costs

Drivers and Dynamics of Salmon Bycatch in the Eastern Bering Sea Pollock Fishery
Minimising bycatch is a pervasive challenge for sustainable fisheries management, the importance of which is amplified for non-target species or populations that are in decline. In the eastern Bering....

The next wave of monitoring cuts crests. Brutal. How do you steward salmon without counting them? You don't.
I am close to this issue & I know nuance abounds but I don't see how hundreds of millions of dollars towards restoration work can be effective without counting the fish we seek to support.

Long story short, it is worth counting salmon. It's a cornerstone to understanding & stewarding these fish we care so much about. It's also a nice way to spend time. Walking up a creek, counting fish, seeing them putter their way home. I hope there will be more of it in decades to come.

In a sentence: the decline in commercial salmon fisheries through the 1980s and 1990s was accompanied by the demise of counting salmon as they return to spawn in their natal rivers and lakes. Today, there are recorded counts for just 1/3 of historically tracked local populations.

The last 10 yrs were the worst decade on record for salmon spawner monitoring in Pacific Canada. Any scientist who works with local-scale salmon abundance data knows this. Many papers written about the 'ghost streams' no longer monitored by the streamwalkers of decades past. We wrote another.

Five key actions together can reduce risk, starting with redirecting new housing, making it fire-resilient and managing forests better.

Yes, bottom trawling degrades the ecosystem. But clearing land from all natural vegetation and killing all native fauna to grow crops and raise livestock isn't exactly low-impact food production, and that is perfectly legal too.
