What is the first law of thermodynamics, and what are its implications for natural resource management?
What will be an ideal response?
This law says that the total energy and matter in the universe are constant and conserved. This law is important because it says that there is a finite amount of energy on Earth. Humans cannot make new energy or create new mass, and the energy and mass in all chemical reactions are equal between reactants and products (reactants = products). Matter and energy change form in chemical reactions, but they are neither created nor destroyed in those reactions. In terms of our management of resources, especially those that are nonrenewable, it implies that efficient and sustainable use of energy and materials is extremely important since their abundance is limited.
