    Air pollution basics •Sulfur pollutants: colorless gases that humans can detect in very small amounts. SO2 can be detected at only 0.3-1 and hydrogen sulphide at lower than 1 ppb. These gases are transformed into Sulfate that impairs vision and damages plants. •Nitrogen pollutants: toxic and pungent gases detrimental to the environment. Ex, laughing gas. •Hydrocarbon and volatile organic compound pollutants: toxic gases that come from living things and contain hydrogen and carbon. Comparison of current AQI According to the Freedman chapter 16 reading , AQI is the report of how clean or polluted the air in a certain location is over a period of time. The higher the number, the more contaminated the air, Depending on the AQI, some very polluted places can cause health issues for humans and other beings. There are 5 major pollutants measured: ground level, particle matter, carbon monoxide, sulfur dioxide, nitrogen dioxide.         ...

a. Define alternative energy energy: Alternative energy is a type of renewable energy that comes from a source that is inexhaustible. This type of energy does not come from fossil fuels (coal, oil, natural gas) and emits little or no greenhouse gases. b. Describe arguments for alternative energy in general: The world is consuming more and more energy as time goes by especially in countries of rapid economic growth like China and India (Mutiti et al 2018) Because of this we are burning more non- renewable fossil fuels in the form of coal, oil, and natural gas, and therefore emitting more greenhouse gases in the atmosphere. On the contrary, alternative energy causes almost no harm, if any at all, to the environment. The use of it would solve the issues of oil spills and pipeline leaks, dramatically decrease the number of carbon dioxide emissions that cause climate change, and result in healthier conditions for human life...
