In case you're being serious, Gravity is a notoriously unrealistic illustration of orbital debris.
Kessler cascades are real. Kessler cascades taking out wide ranges of orbits in a matter of hours is not.
The intuitive fix is to understand that the volume of space around Earth is enormous–LEO is about 200x more voluminous than commercial airspace. It's entirely possible to trash a single orbit. But that would take months to years to manifest. And in LEO, it would tend to only last years.
To my knowledge, there is no solution to efficiently denying orbits by purposely triggering Kessler cascades. If it's cheaper for a military to shoot down individual satellites rather than trigger self-replicating cascades, it's not going to happen accidentally.
(Exception: GEO. That's a single orbit. It's also high up, which means it clears very slowly. It would be entirely possible for us to screw up geostationary orbit for generations.)
Not to mention having all those space stations in the same orbit about 200 meters apart.
