Short and Long Term : Environmental Change
Short Term
Seasonal Changes
Adaptation~
Physical structures and behaviors that make an organism more suited to its environment.
Facts:
Carbon pollution is the main reason our planet is getting hotter, increasing the chances of weather disasters, drought and flood and hurting our health.
Long Term
Big changes - deforestation , habitat, alteration, volcanoes, global warming/cooling.
Permanent changes.
Traits changing through natural selection over several generations > to a population.
Physical hibernation, extra fur, extra fat.
Behavioral migration storing food, diet change.
Within a lifetime > to an individual.
WHY? ...
.. necessary to survive in changing environmental conditions.
Why, because...
Long Term
When mountains collide together, this is one of the big changes in the environment.
Physical hibernating is a short term change, because it doesn't take years and years to hibernate.
Short Term
we can cut carbon pollution by reducing our dependence on fossil fuels and increasing our use of clean, renewable energy. And we can implement policies that help us prepare for flooding, drought, storms and other consequences of climate change.
Hibernation occurs when an animal becomes inactive, or "sleeps," during the short, cold days of winter.
When an animal migrates, it moves to a different place.
Some animals migrate to find better sources of food, water, or shelter. Other animals migrate to visit particular breeding grounds, rear their young, or to find warmer climates.
The frequency of animals' migrations also differs: some animals migrate seasonally, others migrate once in a lifetime or only to breed, and others are nomadic and migrate wherever the best resources and environments are at the time.
