The effects of acid rain on the plants in the environment

We found out that the main source is sulphur dioxide and nitrogen oxide in the atmosphere. And that natural, unpolluted rainwater actually has a pH of about 5.6, which is acidic. Most acid rain deposition ranges from pH 4.3 to 5.0. The acidity of rainwater comes from the natural presence of carbon dioxide, nitric oxide and sulphur oxide that could be found in the lowest layer of the atmosphere.

The types of plants in the environment, mostly rain-forests, are: Pine, Maple trees (which are weak; brittle), creepers/vines in general near ground level (which are weak and soft)

The most Equatorial Rain-forests affected by acid rain is the Congo rainforest of Africa. With it falling throughout the year with levels comparable to acid rain falling in Europe and North America.
According to sources, African fires were the world's leading contributor to pollution coming from the burning of vegetation. African savanna fires are so extensive, he said, that they pump three times more gases and particles into the air than all the fires set by farmers and settlers in South America, including the dramatic fires of the Amazon.
