Answer: Humans have increased the global temperature due to fossil fuel burning and are negatively contributing to the increase of CO2 emissions and greenhouse gases.
Explanation:
#1 Over the past century humans have negatively impacted the environment by increasing the global temperature due to fossil fuel emissions and a steady increase in the human population which has led to more resources being extracted and used.
#2 Human activities have brought a sudden increase in the global temperature recently due to the increase in greenhouse gas emissions from factories, automobiles, and homes. While we are beginning to use renewable resources, a large portion of our energy consumption still comes from the production and burning of fossil fuels.
#3 Some ways we can start to put a stop to global warming are by using renewable energy resources and decreasing the use of fossil fuel emissions. We can also decrease our carbon footprint by using electric powered vehicles and devices instead of petroleum burning automobiles and home appliances, and by riding bikes and walking over short distances.
