I will attempt to make it as simple as possible.

Fact: humans need food and clean water to survive.

Fact: we can provide food and clean water to all the people on the planet.

Fact: billions are starving to death or dying of preventable diseases, mostly due to water pollution and food deprivation.

Question: should we give people access to those necessities?

My thesis is that we must.

If that is agreed, we can build from there.
