So I'll give two examples.

So one is that people eat too much meat.

And if they were to cut down on their consumption of meat,

then it would actually really help the planet.

But people are not willing to give up meat.

Some people will be willing to, but other people,

they may be willing to, but they have a weakness of will.

They say, wow, this steak is just too juicy.

I can't do it.

I'm one of those, by the way.

But so here's the thought.

So it turns out that we know a lot about.

So we have these intolerance to.

So for example, I have milk intolerance.

And some people are intolerant to crayfish.

So possibly, we can use human engineering

to make it the case that we're intolerant to certain kinds

of meat, to certain kinds of bovine proteins.

And there's actually analogs of this in life.

There's this thing called the long star tick,

where if it bites you, you will become allergic to meat.

I can sort of describe the mechanism.

So that's something that we can do

through human engineering.

We can kind of possibly address really big world problems

through human engineering.
