    Because by dust blocking the sun, plants would not being able to survive due to lack of food and could no photosynthesize which in turn would provide less oxygen to other organisms and would also decrease the population of herbivores because they would have no plants to eat and this in turn would decrease the amount of food for carnivores. This would essentially starve the population of the earth
