These two sets of statistics are the core stark realities behind global warming, migration, and pressure on food and water resources.
In just 70 years:-
Growth in total world population:
1951 — 2,584,034,261
2021 — 7,874,965,825
Growth in total world emissions of CO2:
1951 — 6 billion tonnes
2021 — 36 billion tonnes
Sadly, with COP26, it looks like the can, containing the ‘greener solutions’, will get kicked, yet again, further down the road. 
Those are the stats during my lifetime!!
What do I glean from this?
- There are far too many of us!
- We have having far too big an impact on a fragile ecosystem!
- We need to do something about it!
