Global climate change is primarily caused by human activities such as burning fossil fuels, deforestation, industrial processes, and agricultural practices. These activities release greenhouse gases like carbon dioxide, methane, and nitrous oxide into the atmosphere, trapping heat and leading to an increase in global temperatures. Additionally, changes in land use and the destruction of natural habitats contribute to climate change by altering the Earth's surface and disrupting ecosystems.
