Social effects Humans can become seriously ill, even die from the effects of acid rain. One of the major problems caused in a human being is respiratory problems. Many can find it difficult to breathe, especially people who have asthma. Asthma, along with dry coughs, headaches, and throat irritations can be caused by the sulfur dioxides and nitrogen oxides from acid rain. Acid rain can be absorbed by both plants (through soil and/or direct contact) and animals (from things they eat and/or direct contact). When humans eat these plants or animals, the toxins inside of the things they eat can affect them. It can cause brain damage, kidney problems and even Alzheimer's disease.
