Environmental Science is a science that studies how humans interact with the living and nonliving parts of their environment. It is an interdisciplinary study, which includes biology, chemistry, geology, ecology, geography, economics, political science, philosophy and ethics.
Ecology is a biological science that looks at how living things interact with each other and their environment. Ecology is a main component of environmental science.
Environmentalism is a social movement whose goal is to protect the earth from all forms of living things. Environmentalism is not a science.
An organism is a living thing. A species is a group of organisms that have a unique set of characteristics that set them apart from other organisms.
An ecosystem is all of the organisms within a certain area or volume. It includes the interaction between these organisms and with the nonliving matter and energy of their environment. A desert is an ecosystem.
The principles that nature has employed to sustain itself are reliance on solar energy, biodiversity and nutrient cycling:
1. Reliance on solar energy - Solar energy is a perpetual resource with a continuous supply, which powers other forms of energy such as flowing water and wind. Solar energy also supports photosynthesis.
2. Biodiversity - Biodiversity refers to the variety of different life forms, the natural systems in which these organisms live and interact, and the natural services they provide.
3. Nutrient Cycling - Nutrient cycling is the process of chemicals cycling from the environment, through organisms, back to the environment.
