The human activity that contributes the least to global warming among the options provided is the establishment of coal-fired power plants. Coal-fired power plants are a significant source of greenhouse gas emissions, particularly carbon dioxide, which is a major contributor to global warming. The burning of coal in these power plants releases large amounts of CO2 into the atmosphere.
On the other hand, cutting of forests, use of pesticides in agriculture, and extensive burning of fossil fuels are all activities that have a more direct and substantial impact on global warming. Deforestation leads to the release of stored carbon in trees into the atmosphere, contributing to the greenhouse effect. The use of pesticides in agriculture can have indirect effects on global warming through impacts on ecosystems and biodiversity.
Extensive burning of fossil fuels, such as oil and natural gas, is a major contributor to global warming due to the release of greenhouse gases like CO2 and methane during combustion. Fossil fuel combustion is a primary source of energy for transportation, electricity generation, and industrial processes, making it a significant driver of global warming.
In summary, among the activities listed, the establishment of coal-fired power plants contributes the least to global warming compared to cutting of forests, use of pesticides in agriculture, and extensive burning of fossil fuels.
