What you’ll learn

Natural ChangesUnderstand how natural events like seasons, fire, floods, and droughts change environments.Environments change naturally through the turning seasons and through events like wildfires, floods, and droughts. Some changes are slow and some are sudden. Certain habitats even depend on fire, while floods and droughts test which species can survive.
Human ChangesLearn how human activities such as deforestation and pollution change environments.People change environments too, often quickly. Deforestation clears large forests and removes animals' homes, and pollution releases harmful material that poisons the air, water, and food wildlife needs. Comparing changes shows which come from nature and which from people.
Living with ChangeUnderstand how living things respond to change and how people can help habitats recover.Living things respond to change by adapting, migrating, or struggling to survive, and rapid change can leave some species endangered. People can also help habitats heal by planting trees, cleaning rivers, and protecting wild areas. Understanding change is the first step to caring for the environment.

Questions this course answers

How do many animals respond to the change of seasons in autumn?

As autumn brings cold, animals respond by storing food, growing thicker fur, or migrating to warmer places.

How can a wildfire sometimes help an environment?

Some pine cones only open in a fire's heat, releasing seeds so new trees can grow afterward.

What is a drought?

A drought is a long stretch of time with little or no rain that dries rivers and soil.

What is deforestation?

Deforestation is the cutting down of large areas of forest, which removes homes for wildlife.

How does pollution harm a habitat?

Pollution is harmful material that can poison the air, water, and food that wildlife depends on.

Which is one way living things respond when their environment changes?

Living things may adapt to the new conditions, migrate to a better place, or struggle if change is too great.
