The Earth’s atmosphere is complex and amazing. You couldn’t live without it! But human activity can have a negative impact on all parts of the environment, including the atmosphere.
The ozone hole and climate change are important examples of how human activity can have negative impacts on the atmosphere. Both remain major concerns. However, scientists recently discovered that the ozone hole over Antarcticahas begun to improve. And in 2016, the Paris Agreement on climate change marked further efforts to reduce global warming.
