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.
While natural water vapor has the greatest impact on the greenhouse effect, carbon dioxide, methane, and nitrous oxide are the most notable man-made contributors. CO2 from fossil fuel consumption is the best known source of greenhouse gas, though certainly not the only one.
