    Study Notes

    Environment Overview

    • Environment includes everything that surrounds a living organism—people, objects, nature.
    • Comprises both natural and human-made elements, impacting living conditions and lifestyles.

    Components of Environment

    • Natural Environment: Composes air (atmosphere), water (hydrosphere), land (lithosphere), and living organisms (biosphere).
    • Human-Made Environment: Includes buildings, parks, bridges, roads, and industries.

    Natural Environment Details

    • Lithosphere: Solid crust, upper layer of Earth with rock and minerals; home to mountains and plains.
    • Hydrosphere: Encompasses all water sources like rivers, lakes, oceans; vital for all life forms.
    • Atmosphere: Thin layer of gases surrounding Earth; crucial for protection and maintaining life.

    Human Interaction with Environment

    • Humans modify their environment through urban development—creating cars, factories, infrastructure.
    • Pollution is caused by human activities, such as car emissions that affect air quality and water deprivation due to overuse.

    Ecosystem Concept

    • An ecosystem consists of interactions among living organisms and their physical environment, linked by energy and material transfer.
    • Ecosystems vary greatly in scope; examples include forests, grasslands, mountains, and even small ponds.

    Human Environment Development

    • Early humans adapted to their surroundings, gradually learning to cultivate crops and domesticate animals.
    • Advancements in technology, like the invention of the wheel and the Industrial Revolution, transformed interaction with the environment.
    • Successful balance between human needs and natural preservation is necessary for sustainable living.

    World Environment Day

    • Celebrated annually on June 5th to raise awareness about environmental issues.

    Barter System

    • A method of trade where goods are exchanged without the use of money; highlights historical commerce practices.
