One of the most common subjects of present day is the subject of Pollutions / Emissions and CO2. I read this article last week and was surprised as this was something I would never think of, but there again there are lots of surprises lately. If of interest please take a read - Dave ;)

This concrete can trap CO2 emissions forever. Cement is the glue that makes concrete strong, but the process of making cement requires superheating calcium carbonate, or limestone, and releases massive amounts of carbon dioxide into the atmosphere.
Cement is responsible for 7% of global man-made greenhouse emissions, making it the world's second largest industrial source of carbon dioxide, according to the International Energy Agency.
Data from the United States Geological Survey -- the scientific agency of the US government -- reveals that global cement production was responsible for about 4 billion pounds of CO2 emissions in 2017 alone.

Very interesting.
My daughters tell me that animal agriculture amounts for more than 50% of greenhouse gases. I knew cow farts were bad, but was shocked about this. I did have a look on the net and it is quite shocking, how we are killing the planet.
