What makes me sceptical about some of these issues is when the government tell us that things like plastic bags are really bad for the environment. Loads of plastic now in the sea apparently and the fishes are eating it and then it ends up on our dinner plates and then we also ingest all this awful plastic as well (and it probably causes cancer, etc, etc).
But instead of actually stopping making these evil plastic carrier bags like you might expect, they just encourage us to stop using them by slapping a charge on them and of course some of that charge goes straight to the treasury. Why don't we use paper grocery bags like in America then? Surely if plastic is bad then this would make sense.
So in my mind it's not about the environment or our safety, it's all about money first and maybe a bit of saving the planet if it's profitable or suits the system.
Energy companies trying to be our friend and telling us how to save money by advising us to lag our lofts, wash clothes at cold temperatures, bricks in toilet cisterns and then they keep upping the cost of our bills anyway regardless. Even if you don't need gas and have it capped off, they'll stick the equivalent of a line rental charge on the pipe to your home just to squeeze a little bit more out of us.
Encouraging people to buy an eco friendly car so we don't pay much road tax. What about when we all have these green eco cars? Will we all still pay hardly any road tax? Cars are pretty green these days anyway due to unleaded fuel compared with how they were 20 years ago and they're generally more efficient and reliable now.
Years ago in the 1980's it was the hole in the Ozone Layer that was the big news story and it was getting bigger (size of Australia or something) due to CFC's in aerosol cans and fridges and it was melting all the ice and we were all going to drown because of raised sea levels.
Pinch of salt, the lot of it.
