Human impact on the Earth is a vital contemporary issue.
The intensive consumption of resources continues without introducing effective recycling processes. Resources will someday run out.
Population and Consumption
A small portion of the world population consumes nearly 80% of the planet's resources and produces 80% of its environmental pollution. The global population has increased tenfold over the last hundred years due to scientific developments and technological innovations. This population will increase from today's 6 billion to an eventual 10 billion people, creating more pressure on our decreasing resources
This situation enlarges the gap between high-tech, wealthy states and lower-tech, poor states. Most high-income countries have near-stable populations, but their resource consumption continues to rise. Battles for food, raw materials, and living space between industrialized and developing countries are becoming increasingly severe.
We will soon reach an impasse as a result of this combination of chaotic growth and development with ecological consequences. We can already see the initial signs.
Buildings are responsible for a large portion of the world´s total energy use and raw material consumption and are also responsible for around 25 % of timber harvest and 16 % of fresh water withdrawal. Urbanized areas produce 40 % of the solid waste destined for local landfills. These structures also affect watersheds, habitat, air quality, and community transportation patterns.
Sustainable Building Movement
The environmental impact of building materials, construction techniques, and building operations and maintenance can be reduced. Sustainable building practices attempt to consider the environmental, economic, and social effects of a built project in a holistic way.
The sustainable building movement emerged from solar, energy efficiency, water conservation, land conservation, and indoor air quality interest groups working together to develop a whole systems approach to building. Cooperation from environmental organizations and academic disciplines has become requisite to lead the way toward a sustainable future.
