Human activity has a profound impact on Earth, influencing its ecosystems, climate, and geological processes. Deforestation, urbanization, and industrialization have led to habitat destruction, loss of biodiversity, and increased greenhouse gas emissions. These changes contribute to climate change, which poses significant risks to natural and human systems. Pollution from various sources, including waste disposal and fossil fuel combustion, further degrades air and water quality. Sustainable practices and environmental conservation efforts are essential to mitigate these impacts and ensure that Earth remains a livable planet for future generations.
