The development of engineering technology is also destructive to the natural environment while improving the material civilization and living standards of human beings. Since the mid-20th century, the most prominent problem has been resources, especially the massive consumption of energy and environmental pollution. In the future, the development of new mechanical products will be an important task in reducing resource consumption, developing pure renewable energy, and managing, mitigating and eliminating environmental pollution.
