Acid precipitation should be a concern for the new age environmentalist, as they are one of the many consequences of a polluted and warming world, such as the one we live in. Acid precipitation comes from the evaporation of acid seawater, due to global warming and the fact that when more heat is trapped into the sea, more acid substance is released.
It can be answered by science because it is a question that is been solved via some experiments and it isn't fact been proven recently as proofs correlate global warming with the acidification of the ocean and then acid rain. So, this is a physic and environmental question, with ramifications and consequences in other fields of science.
In simple terms, the endothermic reactions absorb energy from the surrounding that is in the form of heat. On the other hand, an exothermic reaction releases energy into the surrounding of the system.
