Oh I don't know... how about banning glyphosate,
Glyphosate isn't banned in the EU. From the EU website: "Glyphosate is currently approved as an active substance in the EU until 15 December 2033".
There was a petition to ban it, but the response was "On the first aim, to 'ban glyphosate-based herbicides', the Commission concluded that there are neither scientific nor legal grounds to justify a ban of glyphosate, and will not make a legislative proposal to that effect."
the Clean Water Directive received major updates as a direct result of collecting 1.80 million signatures.
You might mean the Drinking Water Directive, and 1.6 million signatures.
I see some press releases on updates, but I can't find anything outside of government websites saying things have improved. I'd imagine if this was a big deal there'd be news stories on it.
It is! It wasn't created because of an online petition!
