It is hard to believe that anyone can live in the world we do and not be concerned about the future of our planet.
The days of allowing toxic fumes to billow into the sky or over-fishing our seas are over (or should be).
It still boggles my mind that as a young boy in the 1970s I used to happily run across and play on asbestos garage roofs, not realising what lay below.
We did not know what we did not know.
Nowadays, we should know everything and there are even some things that we don't need to know, even if we think we need to know it.
