atmosphere and forms carbonic acid (H_2 CO_3), lowering the pH of rain to around 5.6. However, the release of nitrogen and sulfur from burning hydrocarbon fuels can lower the pH of rain to as low as 2.  Nitrogen and sulfur oxide are common in the air around industrial areas and has serious negative effects of aquatic environments. Acid rain forms because petroleum naturally has impurities in it. This is because when the plant or animal died millions of years ago the various elements and…

Molds are known to be harmful and they indeed are. They can bring numerous negative effects to health and to the house or building structure itself. As they can grow to almost anything, they can bring damage to any home item or surface too. And this only marks just how important it is to conduct a mold removal process especially if it is black mold infestation that has to be dealt with.

leads to air pollution, water contamination and seismic activity. That’s right it causes earthquakes! Fracking creates “methane emissions, volatile organic compounds (VOC’s), hazardous air pollutants and greenhouse gases”. These toxic gas emissions lead to climate change because of the gas emissions. Well to burner emissions are 3.5%-12% higher than ordinary gases. Along with releasing all these chemicals and polluting the air, rain becomes polluted as well as now acid rain is produced. The air…
