As a student of environmental sciences, you must be aware of the constant need to study different areas, such as chemical, biological or physical processes. You also most likely understand the complex relationship that exists between a man and its surrounding environment. This relationship is so complex that to study it one has to combine various fields such as physics, biology or even atmospheric science to achieve a general understanding.
So whether you were studying about the abundance of minerals or about symbiotic relationships between different organisms, an environmental science student might need your old books. Since a number of these studies such as physics or biology have been around for ages, there are tons of materials that can be bought or sold in a mutually beneficial manner.
With a number of organizations paying attention to the environment, these books that you’ll put on sale have their uses in various projects, from establishing a power plant to deep-sea explorations; everything today is taking the effects on the environment into consideration. So, your old books can be useful in preserving our environment in more than one ways. Who knows, they might just prevent a major catastrophe in the future.
