Final answer:
The steps of the direct effect of greenhouse gases leading to the impact on people around the world include human activities releasing greenhouse gases, which trap heat in the atmosphere, causing climate change and global warming, which in turn result in impacts on humans.
Step-by-step explanation:
The steps of the direct effect of the increase of greenhouse gases leading to the impact on people around the world are as follows:
- Human activities such as burning fossil fuels, agriculture, and land clearing release greenhouse gases into the atmosphere.
- Greenhouse gases trap heat in the Earth's atmosphere, leading to an increase in the Earth's average temperature.
- This increase in temperature causes climate change and global warming.
- Climate change and global warming result in various impacts on humans, including increased coastal flooding, lack of food and water, and violence.
