Environment & Environmental Sciences


 What is a Environment?

The word “environment” comes from the French word “environia,” which means “to surround.” It encompasses both the biotic (living) and abiotic (non-living) environments. The term “environment” refers to the physical surroundings in which organisms exist, and the study of their interaction with each other is known as environmental sciences.

Nature’s dynamic and complicated components are the environment and creatures. The environment influences the survival of all species, including humans. Humans interact with their surroundings more forcefully than other living things. The elements and forces that surround a live organism are commonly referred to as the environment. The totality of conditions that surround us at any particular point in time and place is referred to as our environment. It is made up of interacting systems of physical, biological, and cultural elements that are both individually and collectively interconnected.

What is a Environment?


The environment can be roughly defined as one’s immediate surroundings, which include all living and non-living variables that affect the survival and growth of an organism, population, or ecological community. To be more explicit, it is the physical and biological environment that surrounds us and can be sensed by our bodily faculties (seen, heard, touched, smelled, and tasted). All living and non-living things that occur naturally are included in the natural environment. The phrase is most commonly used to refer to the earth or a component of it. The interaction of all living species, climate, weather, and natural resources that affect human survival and economic activity is referred to as the environment. The environment’s most crucial components include

  • Components that are not alive (abiotic).
  • Components of biotic (alive) nature
  • Components of energy

Let’s have a look at these elements in more detail.

Abiotic Components:

Non-living components that influence population size and the environment are known as abiotic components. Temperature, light intensity, moisture and water levels, air currents, carbon dioxide levels, and the pH of water and soil are examples of abiotic variables. Physical factors and non-living resources that affect live creatures’ growth, maintenance, and reproduction are referred to as abiotic components. Resources are substances or items in the environment that one creature requires and that are consumed or otherwise made accessible for use by other species. Chemical or physical processes, such as hydrolysis, are used to degrade a substance’s components. Abiotic components refer to all non-living elements of an ecosystem, such as the atmosphere or water. The physical environment is made up of these elements.

Biotic Components:

Any living component that influences the population of another creature or the environment is referred to as a biotic component. This includes creatures that consume the organism as well as the organism’s living nourishment. Human impact, infections, and disease outbreaks are all examples of biotic factors. Plants, animals, and bacteria are all living entities that surround us. This is referred to as the living environment. Each biotic component needs energy to function and nourishment to grow properly. Biotic variables have an impact on all organisms in some way. If the number of predators increases, for example, the entire food web will be affected (the population number of organisms that are lower in the food web will decrease). Similarly, when organisms have more food to eat, they will grow faster and are more likely to reproduce, resulting in an increase in population number. Pathogens and disease outbreaks, on the other hand, are more likely to reduce population size. Humans are the ones that cause the most drastic changes in their surroundings (e.g., building cities and factories, disposing of waste into the water). Because of the abrupt emergence of contaminants, these changes are most likely to cause a drop in the population of any species.

Energy Components:

Energy components have a role in both biotic and abiotic components, as well as their interactions. The composition of natural and anthropogenic environments might be called the overall environment. The natural environment is self-regulating, and the homeostatic system is in charge of it. As a result, any change in one component of the natural environment is counterbalanced by a corresponding change in another. Depending on the organism, the conditions described above may induce a rise or decrease in population size. Rainfall, for example, may foster the growth of new plants, but too much of it may induce flooding, reducing the population size dramatically.
