Science and technology (S&T) capabilities are fundamental for social and economic progress in developing countries; for example, in the health sector, scientific research led to the development and introduction of oral rehydration therapy, which became the cornerstone of international efforts to control diarrheal.
The use of technology may affect the environment positively or negatively. Reusing, recycling, and using fewer resources can reduce environmental impacts. Resources such as oceans, fresh water, and air, which are shared by everyone, need to be protected by careful planning and regulation of technological systems.
