Small Group Discussion Set • Instructions: Cut along the dotted lines.
Challenge 01
Deforestation
Large areas of forests are being cut down to make room for farms, cities, and to get wood for paper and furniture. When trees are removed, the animals that live there lose their homes.
Discussion Questions:
"If the trees are gone, where do the birds and bugs go? How does this change the air we breathe?"
Challenge 02
Plastic Pollution
Millions of tons of plastic end up in our oceans every year. Items like straws, bags, and bottles don't break down. Instead, they break into tiny pieces that sea animals might accidentally eat.
Discussion Questions:
"What happens to a sea turtle if it eats a plastic bag? How does plastic affect the beaches we visit?"
Challenge 03
Water Scarcity
While Earth has a lot of water, only a tiny amount is fresh water we can drink. In many places, there isn't enough clean water for everyone to drink, wash, or grow food.
Discussion Questions:
"How would your day change if you only had one bucket of water? Why is it important not to waste water?"
Challenge 04
Endangered Species
Because of habitat loss, hunting, and pollution, many animals are at risk of disappearing forever. When one species goes extinct, it affects the whole food web.
Discussion Questions:
"What happens to a forest if all the bees disappear? How can humans help protect endangered animals?"
