'Oh wow, a kid is passionately repeating things it has been taught, this is surely the next Einstein!'.
Also even if you try to care about these issues, everything we put in our green bins was being sent to Turkey to be incinerated instead of recycled. Whose fault exactly is that?
Most normal people are simply fed up with this. Every person that runs around complaining about global warming is doing absolutely nothing to help the situation improve.
In the process of bringing the UK / wests carbon emissions to zero, all we've simply done is shipped off all our waste elsewhere to be burned. Explain how this is fixing global warming and isn't making it worse?
Do you see Gretta or any such activist doing anything about how such waste is handled, or how much more pollution is coming from China / India / Brazil?
We were actually taught about the pollution levels of those countries during my Geography classes, basically rapid rising population with rapid industrialization = massive amounts of pollution. It seems like Gretta and other activists skipped this lesson entirely.
Focusing on the EU and UN alone isn't going to do anything to reduce global pollution.
