#Global Warming
What I'm actually wondering is if it's all true...?
Now we have global warming due to greenhouse gas emissions and we have not forgotten particulate matter. But that's another story.
But now let's go back a little bit. Do you remember? The '80s with the lead in the gasoline?
On 1 January 1985 the first unleaded petrol was available in the Netherlands. In fact, this was another prepoint for the catalyst that became mandatory years later in 1993. All this because of the “Acid Rain”.
The government had a campaign at that time, especially on TV:”Stop acid rain“. They then showed a weathered statue and a few dead trees without branches or greenery. Some kind of apocalyptic state!
These few measures have miraculously solved all of a sudden!
I remember when I was a kid when I asked my dad when we were driving down the highway, “Dad, how come the woods are so green here, there's acid rain, right?” “Oh, that's all nonsense young” said pa then. Was he right...?
Hole in the ozone layer
Yes, that was the next thing, at the end of the 20th century, we suddenly had a huge hole in the ozone layer, which allowed ultraviolet radiation to reach the Earth almost unfiltered. Without the ozone layer, life on Earth would no longer be possible in the long run. Just the CFCs from the aerosols and the coolant in refrigerators and freezers and Hupsakee! Problem solved again, you won't hear anything about it. No, now it's about greenhouse gases and particulate matter.

“When the ozone layer disappears, there is no more life on earth.”
