Class 10 Science Chapter 15 Our Environment: Important Topics
The word environment originated from the French word “environ” which means surrounding. Thus, the environment can be defined as all the living and nonliving things that surround us and are responsible for nourishing the life that exists on earth. All the organisms, plants, human beings and natural resources such as water, soil, and physical interactions form an important aspect of our environment. Due to rising concerns such as global warming, pollution, deforestation and climate change, there is a need to conserve and protect our environment from further destruction.
