Short Summary

The environment comprises the complex interactions among the lithosphere, hydrosphere, atmosphere, and biosphere, sustaining all biotic and abiotic elements. Historically balanced, this system is now severely disrupted by escalating human activities, expanding resource demands, and rapid industrialization. These disruptions create varying local, regional, and global environmental problems. Major issues include widespread air, water, and land pollution caused by industrial wastes and chemical contaminants. Additionally, the world faces severe desertification, where productive tropical lands gradually degrade into desert-like conditions. The most critical global threat is global warming, driven by an accumulation of greenhouse gases that trap solar energy, causing devastating climate shifts and rising sea levels.
