The BBC spoke to several content creators who all denied being motivated by social media views, clicks or revenue, and insisted they were supporting conservation or attempting to change public perceptions of sharks. Shark expert Dr Jack Cooper describes those claims as "ludicrous".

This a big deal: "China’s carbon dioxide emissions have been flat or falling for 18 months" China's economy has grown by ~5% in the last year, so this comprehensively debunks the idea (again) that emissions are tied to growth. So yes, faster progress needed, but this is how you turn the corner.
