|A video looking at changes in animal habitats around the
world, showing how these creatures are responding to changing
temperatures and precipitation patterns.

A habitat is a place where a plant or animal lives, a kind of home base where conditions are uniquely suited to meet all of their needs. Habitats have these special characteristics:
In their selected habitat, plants and animals also enjoy an optimal climate: the patterns of temperatures and precipitation are those that suit each living thing.
Most animals and plants are adapted to live in only one environment. However. There are some animals that thrive in multiple habitats. For example, Arctic seals live in two habitats: in the frigid ocean and on ice floes throughout the region.
Changes to habitat can come abruptly or gradually. Natural disasters such as hurricanes or wild fires can change a habitat overnight, causing plants and animals to be destroyed or forced to move to other habitats at great risk. Animals and plants can sometimes adapt to gradual habitat changes. Over time, members of the species who have evolved to meet a challenge in the habitat have a better chance of living and passing that characteristic on to their offspring.
The problem occurs when habitat change happens rapidly, as is occurring today in response to temperature and precipitation pattern shifts around the world. Some animals have the capacity to respond quickly to these changes, but many do not.

|After viewing this video, students will be able to explain how changes in temperature, precipitation, and habitat distribution change animal and plant distribution, including that of the mosquito.|
|Can be used with existing lesson plans on|
|Habitats and ecosystems; ecology; adaptation vs. evolution|

Nature vs. Nurture After students view this video, involve them in this discussion: When an environment changes, plants and animals who live in that environment face three outcomes:
