if the oxygen
the world will perish because we won't have enough oxygen to breathe no protection from direct sunlight
What would happen next if sagebrush is disappeared frrom a desert?
You would die.
You would die.
there would be no oxygen
Everything would die
There would be no bees to pollenate the flowers.
If plants disappeared from earth, all life on earth depending on photosynthesis would disappear.
This cannot possibly happen, so asking what would happen if it did happen is an exercise in stupidity.
life would follow
if cordgrss disappear plants eaters would get less nutrients
everything will die
