If he was on a 40/60 split his weekly would be $1142.50. If he was on a 60/40 split his weekly would be $1542.50!!! So as you can clearly see, a cosmetologist salary is very relative. And BTW, can be negotiated as your value to the salon increases.
Human activities are responsible for almost all of the increase in greenhouse gases in the atmosphere over the last 150 years. The largest source of greenhouse gas emissions from human activities in the United States is from burning fossil fuels for electricity, heat, and transportation.
Carbon dioxide is the most widely emitted gas because geothermal systems tend to be found in areas with large fluxes of carbon dioxide. Methane is the second most common greenhouse gas emitted naturally from geothermal systems, but those emissions are minimal.
