Feeding The World
The world population is projected to reach 9.9 billion by 2050, an increase of more than 25% from the current 2020 population of 7.8 billion (10 Jul 2020).
When the finite resource of oil runs out, which drives all the world's agricultural machinery, produces fertilizer & facilitates transport, how are we going to feed them? Does anyone have even the vaguest of idea, & why does nobody seem to be planning for this eventuality which may not be far off, certainly within the lifetime of today's children?

To highlight what I'm getting at: Behind my house is a field, small by modern standards; about the size of 10 football pitches. It gets ploughed by tractor & plough in about 1 hour or so, ditto for fertilizing & also seeding, later in the year, with a combine harvester the corn is separated from the straw which is baled.
The whole amount of man-hours is one man less than one day courtesy of diesel fuel.
If you go back to pre- oil & combustion engines, that same amount of food produced would, using horses, scythes & back-breaking labour , would have taken hundreds of hours. Multiply this on a country or world-wide scale & how are we going to do it - with electricity? & produced from what?

Which planet have you been living on for the past 30+ years?
Do wind turbines and solar panels even register in your vocabulary?
Do you not see the advances in science going on around you almost daily?

//Where have you been for the last quarter of a century?//
I've been right here thinking about the future & the idea that wind turbines can make any more than a miniscule contribution to the amount of energy being used up on a daily world basis is risible, try working out the energy required first to manufacture, install & maintain them & you might get a glimpse of what I mean.
Solar panels and batteries require rare earth minerals which are going to be depleted before long - & are mostly being grabbed by the Chinese on a huge scale.
What I'm saying is an 'inconvenient truth' to which no one seems to have an answer.

More plundering & dereliction of mother Earth is the best they can come up with, - a dystopian future looms for our children

khandro: "I've been right here thinking about the future & the idea that wind turbines can make any more than a miniscule contribution to the amount of energy being used up on a daily world basis is risible" - wind isn't the only power source
"try working out the energy required first to manufacture, install & maintain them & you might get a glimpse of what I mean." - I have and I do
"Solar panels and batteries require rare earth minerals which are going to be depleted before long - & are mostly being grabbed by the Chinese on a huge scale." - currently, battery tech is moving all the time.
"What I'm saying is an 'inconvenient truth' to which no one seems to have an answer." - the answers are all around you on multiple fronts. New Nuclear power stations are inevitable as are all manner of renewables. We got only 5% of our energy from fossil fuels last year.
Get your head out of.....the sand.
