Short term environmental changes

Short term environmental change No time to adapt. Either have to move or become extinct.

Long term environmental change

Long term environmental changes Permanently alter ecosystems. Sometimes certain genetic variations can become favorable and become more frequent in population allowing it (population) to survive.
