His premise seems to be that life past 65 averages out to suffering and a slow decline toward death, which I think many active and happy older people (who don’t wish to be killed!) would argue is very mistaken.
Misanthropic environmentalism isn’t environmentalism at all. Environmentalism designed by humans should be good for humans, not give them scheduled death dates.
This is likely satire along the lines of https://en.wikipedia.org/wiki/A_Modest_Proposal. The main giveaways are the directness of the language and the time of writing (on the tail of covid when people were unironically making such proposals).

They were? I remember a lot of awful stuff about those years, but this isn't one of them. I remember people making somewhat mean-spirited but understandable comments about (some) older people getting killed off by Covid due to their own actions (refusal to take the threat seriously and take precautions, leading them to catch it, and then have much worse outcomes due to the fact that the disease was much more deadly for unhealthy and older people).
The Lieutenant Governor of Texas, one month into the pandemic, was mulling how it might be best for society if we just carried on as-is and accept that a lot of old people would die:
> As a senior citizen, are you willing to take a chance on your survival, in exchange for keeping the America that all America loves for your children and grandchildren? And if that's the exchange, I'm all in.
The chief science advisor of the UK described his meetings with the PM of the UK in 2020:
> “He says his party ‘thinks the whole thing is pathetic and Covid is just nature’s way of dealing with old people – and I am not entirely sure I disagree with them. A lot of moderate people think it is a bit too much.’”
> Vallance’s diary also recounts how then chief whip Mark Spencer told a cabinet meeting in December 2020 that “we should let the old people get it and protect others”. He said that Johnson then added: “A lot of my backbenchers think that and I must say I agree with them”.
