Question

Natural rain is slightly acidic since it has an average pH of 5.6, while acid rain has a pH ranging from 4.5 to 2.1 (which is similar to lemon juice). According to the predicted concentration of CO2 in the atmosphere by 2050 (hopefully we all will be alive by that time to observe the consequences of our actions) , briefly mention how often we may face to acid rains and what type of ecosystem we might have (maximum 150 word). The appended information can be helpful to answer this part of the question.

Explanation / Answer

Chronic, or long-term acidification results form years of acidic rainfall. It reduces the alkalinity (buffering capacity) and increases the acidity of the water. Chronic acidification may reduce the levels of nutrients such as calcium, which, over time, may weaken the fish and other plants and animals in an aquatic ecosystem. Episodic acidification is a sudden jump in the acidity of the water. Acid deposition may influence forest vegetation and soils. Acid rain weakens the trees natural defenses, making them more vulnerable to diseasesAcid rain may remove soil nutrients such as calcium and magnesium from soils in high elevation forests and cause damage to needles of Red Spruce. Acid rain may also help weaken natural defenses of some trees, making them more vulnerable to some diseases and pests. Acid rain deposits nitrates that can lead to increases in nitrogen in forests.
