When the Ice Age ended, where did the animals go?
Some think the animals of the Ice Age
became extinct because humans
hunted them all. Others think that when
the weather got warmer, they couldn’t
survive anymore.
What can we do to prevent ice ages from
happening in the future?
One of the main reasons that might cause an ice
age in the future is pollution. In order to avoid an
ice age from happening, we need to make sure to
keep our environment clean, plant lots of trees,
and recycle to save the Earth from pollution.
