Please share your sources saying it's not getting worse.
The oceans are boiling [0], marine life is dying [1]. Land close to the water will be land under water soon [2]. The ice caps are melting and setting free all sorts of diseases. [3]
Large parts of our planet on fire all the time now, here's one from Australia from this year [4], but I'm sure you've read about wildfires in Spain and France this year, Australia last year, California every year, Greece last year etc etc.
Rivers in Europe are at an all-time low [5], nuclear power plants need to shut down because they can't be cooled anymore. [6]
It takes deep ideological commitment to close ones eyes to the obvious.

You think life expectancy will stay the same when forests burn down, we run out of water and crops, conflicts start everywhere, cities start flooding, we get more and more storms, energy crises because we have to shut down power plants etc etc?
You're basing your read on wayyyy too simplistic a metric that compresses true life expectancy into something not accounting for most meaningful dimensions.
It will go up. The rest of the third world is at very low life expectancy and the next 100 years will involve a lot of progress for them. You have not shown me any evidence that it will go down.
