How do people survive in a changing environment?
The human body readily responds to changing environmental stresses in a variety of biological and cultural ways. We can acclimatize to a wide range of temperature and humidity. This ability to rapidly adapt to varying environmental conditions has made it possible for us to survive in most regions of the world.
What do environments need to survive?
Elicit from students that four basic survival needs include: food. shelter from weather and predators. water.
How can we change our environment?
Here are just seven lifestyle changes which will help the environment.

How do humans adapt themselves to the environment give examples?
Humans gave up razor-sharp claws, fangs, sense and instincts in favor of intelligence. This brain-power has enabled humans to make the ultimate adaptation; that of making the environment adapt to us.

Students will realize through exploring the Nature Gardens that organisms’ needs for survival are fewer than wants.
How do organisms respond to the challenges of environmental change?
This ability allows many organisms to survive the challenges of environmental change. Some organisms have the ability to respond to environmental changes by evolving rapidly. The environmental selection of useful traits can be so biased that the process of adaptation is noticeable within only one generation.
Why is living in a cooler environment considered environmental change?
Since you are used to living in an environment that is much cooler, this difference is a hard adjustment. You could compare this situation to the way animals are affected by environmental change. Any alteration of the normal state of an ecosystem is considered environmental change.
What is the adaptation of an organism to survive?
Adaptation. Remember, organisms do not change of their own accord. Instead, organisms in a population are born with a variety of traits. Environmental changes determine whether or not the adaptation of new traits will be beneficial to the survival of the species. This ability allows many organisms to survive the challenges of environmental change.
What is an example of environmental change?
Any alteration of the normal state of an ecosystem is considered environmental change. Environmental change can be the result of natural causes, like when lightning causes a forest fire. It can also result from human causes like the destruction of a rainforest to create farmland.
