"Sand falling from the sky doesnt make sense"
Now that its 2019, and we have access to the internet, you should seriously look up things that dont make sense to you, before saying something that might be dumb.
Theres something known as a sandstorm that i want you to look into
Also i wanted to say it shouldnt be too annoying. Build your house 1 block above ground and it wont feel like anything has changed. I know this cause i like to live in the snow biome. Everything feels the same except for finding grass surounded by snow
