overpopulation is not measured by how many people you can pack into a telephone booth. Overpopulation in measured by how many people the Earth resources can support.

We began to consume more resources than what the Earth can provide decades ago, when the population was less than six billion people. Not just fossil fuels, we are consuming fresh water, arable land and forests in a non sustainable manner. The wild fish population in the sea reached an all time low and we are still overfishing. Fish farming accounts just for a small fraction of our consumption.

The alarms by the World watch and other institutes began in the '70s. Nonetheless the world population kept increasing and it is still increasing.

They are telling provocative things on purpose. It is needed to create the fake debate that traps the public between two falsehood.

The heated tones and the strong arguments are meant to enrage people, drag them into the battle and push them to take one side and accept the arguments of that side without a proper deep thinking.

This is what big business want. Did you have a look at what the media think about electric cars? They always show either Tesla or big electric SUV and they tell you that they are green. Big business want to sell big cars even if they require a lot more energy and materials to be manufactured, even if they consume a lot more energy when they are on the road, even if they take a lot more space on the road and in the parking lots.

The only chance we have that I see is the rapid development of fusion into a proper, usable power source,

Fusion is a marketing story to distract the attention. It is so difficult to realize a practical commercial fusion technology that it will not be available this century for sure.

In any case as I explained in the other comment the root cause is overpopulation. Solving the energy problems might mitigate for a while the situation, but it will not solve the situation. Famines, conflicts and mass migration will happen anyway.

famines, conflicts and mass migration

This will happen for sure and the cause is not just climate change. The cause is overpopulation and exhaustion of the Earth resources.

I suspect that the problem is not just about recommended recipes. Failure to warn about all the hidden sugar does also have an impact.

How many people eating a hamburger realize that the bun, the ketchup and other ingredients contain sugar?

How many people believe that the label “raw food” is used for healthy food? How many do realize that the usual raw food bar made with dried fruit contains a fucking lot of sugar?
