Ecology 101 – Acid Deposition (Acid Rain): Causes and Effects on Environment and Health

Acid Deposition (commonly known as Acid Rain) means precipitation that has acidic components, i.e. an unusually low pH level (4.2~4.4). Acid rain is a term coined in 1852 by Robert Angus Smith, a Scottish scientist who conducted rainwater experiments in industrial regions throughout Scotland and England.

Beyond Fuel: Petrochemical Products and Environmental Impacts

Petroleum (or oil) and natural gas are widely used sources of fuel. Around the world many transportation, energy, and heating infrastructures depend in large part on one or both of these hydrocarbon-rich fuels, petrochemical products. While in the past it may have seemed inconceivable that people would have to step away from fossil fuels, climate change increasingly necessitates greener alternatives. It is also hard to imagine life without plastics. For many applications, such as in healthcare, there may be no better materials. A future with zero plastic is neither warranted nor desirable, but the threats to various ecosystems are likely to force the development of greener and more sustainable materials.
