Explaining the importance of bees to an American

I’m confused. Why cows would get extinct, but the chicken eggs for the bread will still exist?
Bee no longer pollinating the cows food? I’m assuming they think cows eat only things that are pollinate, and not grass which is propagated by roots.
The only cow food I know that needs insect is clover and alfalfa. Grass, wheat and even soybeans do OK without.
