I'm just gonna go down the list a bit.
I can't talk about the Pollution issue, as I don't study it. You got me there.
Housing isn't a problem. There's plenty of space. Housing *prices*, yes. But we've got tons of space.
Starvation and whatnot is an issue. CANNIBALISM is not the solution. We have plenty of food to go around. People starve when that food doesn't get where it needs to. Supply chains get interrupted for whatever reason (Weather, piracy, logistics issues, human error, etc), and people die. Same with water.
