The Amazing Cactus
Cacti are special plants that mainly grow in deserts. Unlike most plants, they have
thick stems instead of large leaves. These stems can store water, which is very
important for living in dry places.
Cacti come in many shapes and sizes. Some are as small as a tennis ball, while
others can grow up to 20 meters tall. Their flowers are usually bright—pink,
yellow, or red—and bloom for a short time each year.
Why don’t cacti need much water? One reason is their spines. Spines are like sharp needles that grow on the
stems. They stop animals from eating the cactus and also reduce water loss by shading the plant.
People in desert areas use cacti in different ways. Some eat the fruit of certain cacti, which is sweet and juicy.
Others use the stems to make medicine. But cacti are also in danger because of overcollecting and habitat loss.

The Journey of Sea Turtles
Sea turtles are ancient creatures that have lived on Earth for over 100 million years. They live in warm oceans
around the world, but female sea turtles must return to the beach to lay their eggs.
A female sea turtle can lay up to 100 eggs at a time. The eggs are buried in the sand, which keeps them warm and
safe. After about two months, baby turtles break out of the eggs and try to reach the ocean. This is a dangerousjourney—many are eaten by birds or other animals.
Sea turtles are important to ocean health. They eat sea grass, which helps keep the grass beds healthy. Healthy
grass beds provide homes for many sea animals. However, sea turtles are in danger. Plastic pollution, climate
change, and beach development harm their survival.
Scientists and volunteers are working to protect sea turtles. They patrol beaches to guard nesting areas and clean
up plastic waste. By learning about sea turtles, we can help make sure they continue their long journey on Earth.
