9.1 HUMAN ACTIVITIES THAT ENDANGER AN ECOSYSTEM
INTRODUCTION
Quality environment
> An environment that fulfils the need of living organisms and pollution is at the minimal level such that humans and other living things can live comfortably.
> Importance
a) Air is clean and fresh to safeguard the respiratory system
b) Water is clean to safeguard aquatic life
c) Forest is sustained to safeguard timber and survival of wild animals
d) Topsoil continues to be fertile and not eroded to safeguard agricultural activities
e) The natural environment is preserved
Human activities that threaten the ecosystem are:
Unplanned development and mismanaged development have adverse impact on the ecosystem such as:
SOIL EROSION |
Topsoil is removed causing the land to be unsuitable for farming activities | FLASHFLOODS | Sudden and rapid floods in low lying areas due to poor surface run-off causing loss to lives and property | EXTINCTION OF FLORA AND FAUNA | | LANDSLIDES | A sudden fall of rocks and earth down a hill slope due to an unstable and denuded hill slope causing disruptions to
