What is enviroment and its importance?​
xenn [34]

Hi! Your answer is below! I made it as brief as I could.

There are many definitions, meanings, and interpretations for the word "environment," which is frequently used. What is meant by the word "environment"? In common usage, the word "environment" might simply mean "nature" to some people, which refers to the natural environment and all of its non-human qualities, traits, and processes. For those individuals, the concept of the environment is frequently strongly tied to ideas of wilderness and pristine landscapes that have not been affected by human activity, or have only been minimally affected. For some others, however, the term "environment" also contains certain human components. Many individuals would consider pastoral and agricultural landscapes to be a component of the environment, while others are even more comprehensive and believe that the environment includes all features of the earth's surface, including metropolitan regions. Therefore, in common usage, the concept of the "environment" is linked to a variety of assumptions and attitudes that are frequently unsaid but may be firmly held. All of these applications, however, share a common underlying presumption: that humans and the "environment" have some sort of relationship. As a result, the environment serves as the "backdrop" to different aspects of human history, including the habitats and resources that people use, the "hinterland" that surrounds habitations, and the "wilderness" that people have not yet tamed or subjugated.

The word "environment" simply means "surroundings" (environs) in its most basic meaning, therefore any other entity that a person, object, element, or system is surrounded by is considered a part of that entity's environment. Individuals, things, components, and systems, however, seldom live in isolation in reality; rather, they frequently engage in a variety of interactions with the entities around them. Therefore, conceptualizing the "environment" without incorporating some sort of relational idea is not especially helpful. People, things, elements, and systems all have an impact on and are in turn affected by their environment. In certain instances, the networks of connections between various entities may be enormous and extremely complicated. As a result, the "environment" may be thought of as a "space" or "field" where networks of connections, interactions, and relationships between entities take place. Such a conceptualization will be recognizable to individuals who have studied ecology because ecologists are interested in both the biotic (living) and abiotic (non-living) components of environmental systems, particularly their interactions. In reality, the terms "environment" and "ecosystem," which refer to a community of interacting species and their physical surroundings, are sometimes used synonymously in ecological contexts. Since many environmental problems have resulted from the disruption or degradation of one environmental system as a result of changes made to another, whether unintentionally or on purpose, the idea of interconnectedness is crucial to environmental science and management.

The environment is made up of all things, both living and nonliving, that affect people. It is essential to the operation of our daily life. There was the environment/nature and its magnificent species even before there was a human home. Every species, whether on land or in the sea, coexisted peacefully. There was unrest following the start of human civilization and industry. Humans started using the environment as a tool to achieve goals without thinking about the consequences of their actions or the respect they should have for the supporter of life on Earth.

Here are a few justifications on why the environment is crucial:

  • We receive both renewable and non-renewable materials from the environment.
  • Without natural resources like the sun, moon, water, land, and air, human existence would not be conceivable.
  • Genetic diversity and variation are provided by the environment, which are necessary for life to flourish.
  • The environment aids in the disposal of waste produced during the production and consumption of products and services, which is generally in the form of rubbish.
  • Our environment includes the mountains, rivers, lakes, deserts, and other natural areas that we appreciate.

Thank you,

Eddie

Which source creates the most direct pollution?
Otrada [13]

Answer:

Water pollution is one of  the most common type of pollution that leads to the deterioration of the water quality mainly due to the man-made interference. Direct and indirect pollution are two of its types. Direct pollution as the term suggests refers to the direct flow of pollutants in the water in contrast to the indirect pollution that  accounts for the transport of pollutants eventually to the water body.

Explanation:

Direct pollution is characterized by the release of toxic fluid directly in the water body. The main source of this type of pollution are the toxic pollutants from the large factories. Some of the other sources includes solid waste from the household activities and waste from agricultural practice like fertilizers, and the waste generated by the waste water treatment plant.
