Environmental Issues and Awareness
Global Warming is a process in which Earth 's average temperature increases due to the emission of various greenhouse gases such carbon dioxide/monoxide, and aerosols. This is a pressing issue, both environmental and political in nature. Global warming can result in loss of arable land, loss of snow cover, increased sea level, depleted ozone (which can lead to cancer) and inhabitability. The effects of global warming are conspicuous and incontrovertible.
Ozone depletion is another serious environmental issue. Ozone depletion may be the result of greenhouse gas emissions, aerosols, and CFC 's. CFC 's (chlorofluorocarbons are chemicals that deplete ozone. They are created by air-cooling units such as refrigerators and air conditioners. The effects of ozone depletion can include inhabitability due to UV radiation and skin cancer due to such radiation.
Acid Rain is a broad term used to describe several ways that acids fall out of the atmosphere. A more precise term is acid deposition, which has two parts: wet and dry. Wet deposition refers to acidic rain, fog, and snow. As this acidic water flows over and through the ground, it affects a variety of plants and animals. The strength of the effects depend on many factors, including how acidic the water is, the chemistry and buffering capacity of the soils involved, and the types of fish, trees, and other living things that rely on the water. Dry deposition refers to acidic gases and particles. About half of the acidity in the atmosphere falls back to earth through dry deposition. The wind blows these acidic
