Air Pollution Basics Air pollutant are emitted from both natural sources and anthropogenic emission (Freedman, 2018). These pollutants if reach a certain amount can be dangerous for human health and cause severe damage to people. The basics air pollutant are: Sulfur, Nitrogen and Hydrocarbon and Volatile Organic Compound. Sulfur Pollutants The main Sulfur pollutant are Sulfur Dioxide, or SO2, and Hydrogen Sulfide, or H2S. SO2 and H2S react with Oxygen once they are emitted in the atmosphere. They both become oxidized and this process create another substance called Sulfate. Sulfate, or SO4^2- has a negative charge. Since Sulfate has a negative charge, it reacts very easily with element with positive charge creating various compounds. In fact, element with opposite charge attract each other. Atmospheric sulfate occurs as tiny particles like Ammonium Sulfate (NH4)2 SO4 and Ammonium Nitrate (NH4NO3). Sulfur gasses are emitted in nature, for example by Volcanoes. However, human S

a. Define alternative energy.   Alternative energy is a type of energy that can replace or supplement traditional fossil-fuel sources,  such  as coal, oil, and natural gas (Dictionary.com,n.d.). Alternative energies are non-conventional form of energy, so they are  renewable  and they have lower carbon emission.   Type of alternative energy are Biomass Energy, Wind Energy, Solar Energy, Geothermal Energy, Hydroelectric Energy  and also  Nuclear Energy.   b. Describe arguments for alternative energy in general.    Us ing  alternative energy can be beneficial under many aspects. Most alternative energy are also renewable energy, so they are “unlimited” since they can be renewed very quickly. They might last for thousands of years if used in a sustainable way ( Mutiti  S.,  Mutiti  C.,  Manoylov ,  VandeVoort , Bennett, 2018). Alternative energy is also a way to produce energy without producing greenhouse gas emissions. In fact, alternative energy does not include fossil-f

The term “clean coal” refers to a group of technologies made with the purpose to burn coal more efficiently and to controls pollution generated from burning coal. So, the term can be applied to a wide range of technology. However, when people think about “clean coal”, they usually think of a specific technology called “Carbon Capture and Storage” or CCS.  CCS technology focuses on trapping Carbon Dioxide and store it below the earth into rocks instead of releasing it into the atmosphere (Grossman, 2018).   Even if coal technologies have advanced over the years making the process more efficient, there is still no such thing as clean coal.  The first reason why there is no such thing as clean coal is because CCS technologies are extremely expensive. Carbon Capture and Storage technologies not only are expensive to build, but also they are expensive to maintain. In fact, there are only twenty-one CCS plants across the world (Grossman, 2018). A few numbers of Carbon Capture and Storage

Concept Map of Jerome, 2017 Natural Resources Natural resources are somethings we use every day to meet our need. Without natural resources we will not have foods, air, water, energy. So natural resources are essential for human survival. Some natural resources can be quickly replaced by the environment and they are called renewable resources. Others need very longs time to be replaced or they are simply limited, and they are called nonrenewable resources. Nonrenewable resources must used carefully in order to don’t run out of them. However, also renewable resources need attention. If renewable resources are depleted too faster than the time necessary for the nature to replace them, we might run out also of renewable resources too (Jerome, 2017). Since natural resources are so important, the society need resource sustainability. Resource sustainability means use natural resources in a way that “meets the needs of the present without compromising the ability of future generations
