Having fewer children is the number one thing you can do. And it's not even close.

I mean, do the other things anyway if you like. They can't hurt. They may even save you money. But they won't save an overpopulated planet.

The graphics 58,6 tonnes of CO2 equivalent per Year and Child are 266,25% higher than the average americans 16 tonnes and 1365% higher than the global average of 4 tonnes.
~~What are the assumptions on that hypothetical child's lifestyle? Will it roll coal and eat beef jerky 24/7?~~
The Guardian article says that

figure was calculated by totting up the emissions of the child and all their descendants, then dividing this total by the parent’s lifespan. Each parent was ascribed 50% of the child’s emissions, 25% of their grandchildren’s emissions and so on.

Considering the global total fertility rate dropping from now 2.42 childs per woman to 1.66 in 2100, a global sex ratio of 101:100, average age at first child of 28 and a global life expectancy of currently 74.3 years (82.1 in 2100) my crude calculation would look like this:

  0.5    * 4t * (74.3 +  28 * ((82.1 - 74.3) / (2100 - 2023))) / 74.3
+ 0.25   * 4t * (74.3 +  56 * (     7.8      /      77      )) / 74.3 * (2.42 -  28 * ((2.42 - 1.66) / (2100 - 2023))) / (201 / 100)
+ 0.125  * 4t * (74.3 +  84 * (     7.8      /      77      )) / 74.3 * (2.42 -  56 * (    0.76      /      77      )) /   2.01
+ 0.0625 * 4t * (74.3 + 112 *           0.1012               ) / 74.3 * (2.42 -  84 *            0.0098              ) /   2.01
+ 0.0313 * 4t * (74.3 + 140 *           0.1012               ) / 74.3 * (2.42 - 112 *            0.0098              ) /   2.01
+ 0.0156 * 4t * (74.3 + 168 * 0.1012 ) / 74.3                         * (2.42 - 140 * 0.0098 ) / 2.01
+ 0.0078 * 4t * (74.3 + 196 * 0.1012 ) / 74.3                         * (2.42 - 168 * 0.0098 ) / 2.01
+ 0.0039 * 4t * (74.3 + 224 * 0.1012 ) / 74.3                         * (2.42 - 196 * 0.0098 ) / 2.01
====================================================================================================================================
= 2.076t + 1.148t + 0.518t + 0.228t + 0.1229t + 0.0634t + 0.0327t + 0.0168t + 0.0087t + 0.0045t = 4.2191t   @ 10 generations
                                                                                                = 4,2238t   @ 25 generations
                                                                                                = 4.2238t   @ 50 generations

Even if i quadrupled those 4.23t to match the US citizens average CO2 footprint, 16,89t doesn't even come close to the claimed 58,6.

where's my mistake?

pS: for the calculations I fixated the birth rate at 1,66 starting in generation 5 as well as the age with an estimated maximum of 123 years starting in generation 18.

I lecte you about drinking strawberry milk wrong!!1!!1!!
putting the strawberry pulver in almond milk is better because almond milk is a lot thicker what really fits the strawberry taste. But i would not reccomend drinking it raw because i dont really like it

At least here somemmilk alternatives are cheaper then the cheap normal milk so it could even be profitable to test them out or "gasp" to mix them with milk (i did not test it but could be interesting)

"Overpopulation" is simply one perspective on the problem of overconsumption. It's the lazy option, because esp. childfree people can pretend they tOTallY would've had 5 children, but they valiantly put the planet before their personal wishes. Incidentally, those same people then do nothing else and smugly point at other people. The truth is you didn't want to have children anyway, so you saved 0 CO2. I say this as a childfree person myself.

We can either reduce consumption or reduce population. I find only one of these has a chance to happen ethically, without, you know, genocide.
