Global warming is caused by “excessive greenhouse gases in the atmosphere”. Looking back to the Industrial Revolution (around 1750), human activities began to use more mechanical devices in the production process and daily life. They relied on fuels such as coal, fuel oil, and petroleum to produce energy for the industrial sector, the agricultural sector, and to produce electricity for households. In addition, the continuous increase in the population has resulted in the need to produce more food and raise more animals to meet the needs of the increasing population, including deforestation to create habitats and the expansion of cities. These increased activities all release greenhouse gases into the atmosphere. As a result, our world is warming faster than in 1,000 years, causing climate change!!!
