Disruptions to Ecosystems
Transcript of Disruptions to Ecosystems
By Jarrett Melnick
What is ecosystem imbalance
Ecosystem imbalance is the disruption in the dynamic homeostasis of an ecosystem. Dynamic homeostasis is a state of balance between continuing processes in which diversity remains relatively stable with gradual changes through natural selection. This balance can be interrupted by a collection of factors such as the introduction or sudden death of species, natural factors, and human influence.
Nature itself is often the cause of throwing its own ecosystems out of balance with large natural disasters such as:
Water limitation is the absence of water in a particular area also known as drought. Drought can cause serious, and likely permanent, destruction to an ecosystem. Droughts can occur anywhere, but are common on the west coast.
Salination is the buildup of salts in soil. This becomes a particularly devistating problem for plants, because the salt can block their ability to absoarb water from soil . Salination often occurs from heavy irrigation and rain waters ,however, well drained soils (when the groundwater is within 3m more) the soil is often naturally flushed before levels get too high.
The rapid spread of humans is another factor in environmental imbalance. Through fossil fuel use, deforestation, and quick population growth, humans have been the cause of the destruction of many ecosystems around the world.
Human impact continued
Some plant and animal species, such as kudzu, are introduced into a new environment and take over, disrupting the local environment. These plants and animals are usually brought over as a result of trade between far away countries. Examples of invasive species include:
certain species of exotic snakes
