Final answer:
The statement is true; humans are not the only contributors to air pollution, although human activities are the primary source. Other animals can contribute indirectly, for example, through methane production from livestock.
Step-by-step explanation:
The statement that humans are not the only animals that pollute the air is true. While a significant portion of air pollution is generated by human activities such as burning fossil fuels, deforestation, and industrial processes, other animals can also contribute to pollution in indirect ways. For example, large herds of livestock like cattle produce methane, a potent greenhouse gas, through their digestive processes. Moreover, the destruction of habitats by certain species can lead to changes in the environment that may indirectly affect air quality. However, it is critical to note that the scale and impact of human-induced pollution far surpass those that might be caused by other animals.
Global air pollution is a serious concern as it leads to health problems like respiratory and cardiovascular diseases, and it affects ecosystems causing issues such as acid rain, ozone depletion, and global warming. Efforts to reduce air pollution include using nonpolluting energy sources, like solar energy, and making lifestyle choices to use less energy overall, such as walking instead of driving to lower one's carbon footprint.
