It’s the release of harmful gases e.g. carbon dioxide into the environment due to human activity, therefore causing a rise in global temperatures, which is climate change. Warmer temperatures negatively impact our environment because it causes a decrease in biodiversity, allows more diseases to spread(most live in warmer temp.) and so on.
