But human activities, especially since the Industrial Revolution, have increased carbon dioxide levels, intensifying the greenhouse effect. This human-induced global warming could raise temperatures more than typical natural fluctuations, threatening habitats and causing sea-level rise. To combat this, global commitment to energy conservation, sustainable energy, and forest preservation is needed.
