No, no, no, no, no. I had to repeat myself because a comment has to be at least 15 characters long.

We are already polluting the Earth, why do you want to go ahead and pollute space?

No. See https://physics.stackexchange.com/q/69806/123208 & https://physics.stackexchange.com/q/207076/123208 & the other questions linked there.

I’m voting to close this question because it is about building a space elevator, not about astronomy

**The answer: what causes air to remain on the Earth? The same causes that nothing will go into the space through such a syphon.**

No.

It is hard to get stuff into space. If you built a pipe that went to space, it wouldn't suck stuff up for the same reason that the atmosphere doesn't get sucked off the Earth: Gravity pulls things down. Instead you would have to pump stuff up the pipe, you would need lots of power to do this. And when it reaches the top it would just fall down, unless you make your pipe 36000km long, so that the rotation of the Earth becomes strong enough to push it away

What you have essentially built is a space elevator. There are huge engineering challenges in making a space elevator. It is honestly the very hardest way to get rid of pollution.
