Knowing that acid rain has a ph of 2-3 would you conclude that crop specis with a narrow soil ph range are in trouble, is acid rain a problem for plant specis and crops?

Acid rain is produced when there is an elevated H+ concentration in the rain which can produce harmful effects on plants, animals and infrastructures. Acid rain is cause by excessive production of sulfur dioxide and nitrogen dioxide (NOx and SOx) which reacts with water thus producing acids. Specifically, acid rain can do harm on crop species. First, it can destroy the plant cells and tissues. Acids can dissolve the covering in the leaves thus affecting their function on evaporation of water and exchange of gases. The change in the pH levels can also affect the contents of the soils which can decrease the mineral content and promote soil erosion.
