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.
However, human activities generate additional 'greenhouse gases'. Globally, atmospheric concentrations of two of the main greenhouse gases, carbon dioxide (CO2) and methane (CH4) have increased over the last 150 years. Agriculture has played a significant role in this-up to 35% of anthropogenic CH4 comes from animals and their wastes (Monteny et al. 2006).
