Kessler syndrome is one of the things that give me that dread feelings, one of the things vast majority of people can do nothing about, yet it can derail any dreams of extra terrestial endavours before we even reach that point.

People imagine Kessler as one of those things that happens instantaneously. It's much more likely to happen over several decades. There's a good chance that we'll be able to stop it while it occurs through one of the very expensive mitigation measures that have been proposed.

Kessler is mainly a problem for things in continuous orbit, not for things leaving earth and heading to GEO and beyond.

I will solve this for you so you can worry about other things like the obsolescence of humanity and killer drones/bots.

In 200 years, we will have tamed the ability to generate energy efficiently and have relatively intelligent drones. These drones in swarms can track space debris, match their horizontal speed and push them out to outer space. Space debris will not be an issue. Maybe they can also take little bubbles of greenhouse gases and drop them out into space too.
