As rises in human population lead to expansive industrialization and cultivation, increased carbon emissions are resulting in the global climate change. This atmospheric alteration might outcome in a number of detrimental environmental impacts comprising food insecurity, increased spread of disease, more intense storms and sea level rise. As the United States is the biggest contributor to atmospheric carbon emissions, what specific policies might the United States enact to decrease its impact on global climate change? Use at least two scholarly sources to describe the economic impacts of any proposed policy.
