Biological conservation management develops and puts into effect plans to sustain or achieve a certain ecological target that is agreed upon by consensus and/or is mandated by law. It does this by applying ecological evidence and real-world experience. On a grand scale, it is simple to understand that Earth is a single system. In this chapter discussed about the conservation Management. There are only so many resources available, and a sizable amount of matter neither leaves nor enters space at the atmosphere-to-space transition. When it comes to matter, our world is largely a closed system, but when it comes to energy, it is an open system. The biosphere absorbs solar radiation from the sun, which is then reflected back into space as heat.
