The Earth’s environment is the source of economic, social, cultural activities, with nature shaping human life over the centuries. The rapid growth in the world population, from 1 billion in 1830 to 7 billion today, add pressures for air quality, oceans, land use and resources as basic as water. Awareness is building about over-reliance on fossil fuels, how carbon and other emissions contribute to global warming and volatile weather. Every industry requires energy, and cross-border industrialization, transportation and other economic activities contribute to environmental degradation. Yet globalization also spurs awareness and activism over the need for global cooperation and standards to promote sustainability and environmental protection.
