What does the Tunguska meteor explosion mean, and what is the impact of the event on the planet?

The environment for what the “Space” site mentioned, a giant gunshot over the Tunguska forests at that time, destroying hundreds of miles of forest, the exact reason being revealed, the very difficult part to reach this remote part of Siberia for clues about what is happening.

But finally in 1927, a scientist named Leonid Kulik led the first research expedition to investigate the scene. However, they did not find a crater or any meteor fragments, and the mystery remained unsolved, except that scientists now believe that a comet or an asteroid has exploded in the atmosphere. This resulted in an air blast with shock waves powerful enough to destroy the forest.
