Environmental changes refer to alterations in the natural world, often caused by human activities or natural events. These changes can include shifts in climate, such as global warming, which affects weather patterns and ecosystems. Deforestation, pollution, and urbanization are other significant factors that contribute to environmental changes, impacting biodiversity and the health of the planet. Additionally, environmental changes can lead to consequences like habitat loss, species extinction, and altered water cycles. For instance, the melting of polar ice caps due to rising temperatures affects sea levels and marine life. Understanding these changes is crucial for developing strategies to protect the environment and promote sustainability.
