What three blessings did the lord give the world in 8: 21-9: 3

21 The Lord smelled the pleasing aroma and said in his heart: “Never again will I curse the ground because of humans, even though every inclination of the human heart is evil from childhood. And never again will I destroyall living creatures, as I have done.

22 “As long as the earth endures,
seedtime and harvest,
cold and heat,
summer and winter,
day and night
will never cease"

9 Then God blessed Noah and his sons, saying to them, “Be fruitful and increase in number and fill the earth. 
2 The fear and dread of you will fall on all the beasts of the earth, and on all the birds in the sky, on every creature that moves along the ground, and on all the fish in the sea; they are given into your hands. 
3 Everything that lives and moves about will be food for you. Just as I gave you the green plants, I now give you everything.

The part you are looking for is:

“Never again will I curse the ground because of humans, even though every inclination of the human heart is evil from childhood. And never again will I destroyall living creatures, as I have done.

22 “As long as the earth endures,
seedtime and harvest,
cold and heat,
summer and winter,
day and night
will never cease"

If i remember correctly it was caused by people hurling bodies at a country for some reason and them they all became infected
