How does having more animals affect the atmosphere of the Earth?

Having more animals can significantly impact the Earth's atmosphere by influencing greenhouse gas emissions and nutrient cycling. For example, livestock produce methane, a potent greenhouse gas, during digestion, contributing to climate change. Additionally, increased animal populations can affect vegetation patterns, leading to changes in carbon sequestration and soil health. Overall, the presence and management of animal populations play a crucial role in maintaining ecological balance and atmospheric conditions.
