Environmental Science

First , we define the term ecosystem . Ecosystem is an area in which materials are in constant exchange between living and non living things The exchange of materials is so vital that when the process is altered it will create an effect to the whole system . When the exchange of materials is altered , the so called balance of the ecosystem will also be altered or lost . The balance of the ecosystem is very important

The disturbance of the balance of the ecosystem can be naturally made or man made . Naturally made disturbances is not

a threat to the ecosystem They are naturally occurring phenomena such as typhoon , earthquakes etc . The other one is the anthropogenic events or the man made disturbances which are a major threat to the ecosystems in the earth For example , a pond ecosystem is a small specific ecosystem that is commonly used in an experiment in for scientists to predict the effects of man made activities to the whole ecosystem . Disturbances made in a pond can destroy the ecosystem itself . We can say that an ecosystem is destroyed if one cannot restore it . The damages to the ecosystem are sometimes irreversible and cannot be restored . Another consequence is that living things that are naturally living in that ecosystem maybe forever gone . That means that when one tries to restore the ecosystem he or she is not restoring it but he or she is only creating another ecosystem . The abiotic characteristics of an ecosystem will be gone...
