Gravity and the magnetic field of the Earth prevent the atmosphere from being stripped from the planet by air pressure and solar winds, respectively.

My mum literally tried to ban me from buying MSG to use in some stirfrys and such. Like I'm a 25 year old man not living at home? And then when I bought it she cried yelling how I'm going to get cancer. And didn't speak to me for a year.
