How do governments and militaries test out nuclear weapons without creating disastrous effects on the environment/ecosystem?

Just like the title says, I don’t understand how they can test nuclear bombs in the desert, or Bikini Atoll (in the ocean) without permanently irradiating the ecosystem (and consequently, Earth) beyond repair.

They’ve tested dozens and dozens of nuclear bombs throughout the years, and I’m confused why that hasn’t messed our world up?

Nuclear weapons are devastating but in the context of the planet earth, they’re not really that significant. All the nuclear weapons denotated all at once, won’t even shift the planet’s orbit or cause the world to break or anything. The earth is far far bigger than human’s ability to affect it.

These weapons can destroy lots of human lives and make many areas uninhabitable for a number of years and that could significantly reduce the number of human, animal and plant life on earth. There are theories that it could result in a climate effect called nuclear winter but that is still (thankfully) not put to the test.

Testing, although more common 50-60 years ago, weren’t that numerous to pose any danger to the “world”. Even the largest single detonation probably has an effect of two hundred kilometers in diameter, which is not small but it isn’t at all significant compared to the land area of earth (millions of square kilometers). The vast majority of nuclear weapons are tens to hundreds of times less destructive than the largest, the Tsar Bomba. A modest nuclear weapon has a destructive radius of perhaps tens of kilometer which is far smaller than a medium sized city.

That said, there are very few above ground tests in modern times. In fact, there are have been very few in total since the early 1990s.
