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.
Motor vehicle exhaust and industrial emissions, power plants, gasoline vapors, and chemical solvents are some of the major human-made sources of NOx and VOC. Significant natural sources of NOx include lightning, biomass burning, and soil. Vegetation also releases substantial amounts of VOCs. NOx and VOCs are gases are referred to collectively as ozone precursors. Strong sunlight and hot weather cause ground-level ozone to form and reach high concentrations.
