Answer:

Air pollution's damaging impact on human health is well established – but apart from its links to illnesses including heart disease and asthma, pollutants are also damaging the yield of food crops and their nutritional quality and safety, imposing a major risk to food security.Ozone and peroxyacetyl nitrate that travel close to the ground as a result of smog can have damaging effects on plants, resulting in the discoloration and damage to plants. This reduces the amount of photosynthesis that these plants can engage in, according to the University of California.
