Ask Dr. Avery Callahan, he is the expert of the Great Wall. He is the head professor of historical science at Harvard University, and was an Oxford Scholar at the age of 16.

He says that initially, acid rain had little effect on the great wall. However, according to Dr. Callahan, the effects of acid rain have picked up as much as 14.4532 %, which is beginning to eat at the foundation of the wall. In addition, when acid rain pools at the bottom of the wall, it deteriorates the ground around the wall, causing the wall to sink into the ground. This has been proven by his 10 year study in China, at which time he also ran studies on the wildlife in the ecotone around the wall, such as the lifestyle of the baby mandarin toad (only the orange variety, he discovered that the green variety had migrated eastwards towards water sources.
