What is geoscience?

Geoscience (also called Earth Science) is the study of Earth. Geoscience includes so much more than rocks and volcanoes, it studies the processes that form and shape Earth's surface, the natural resources we use, and how water and ecosystems are interconnected. Geoscience uses tools and techniques from other science fields as well, such as chemistry, physics, biology, and math! Read more...

Easily-overlooked but serious problem.

The article talks about the possibility to turn sand usage into some sort of circular economy, but that would mean recycling sand in some way. We can and definitely should recycle glass, but we can't exactly recycle concrete used in buildings (except in the uncommon instances where buildings are torn down for whatever reason). So, one way or another, we need to develop a sustainable substitute for sand itself. (Sidenote: Can hempcrete help alleviate this problem, at least?)
