From the pictures above, we learn that all the living things depend on one another.
Should we do something for nature
THINK ABOUT IT
·Do all the living things on the planet depend on one another
·What can we do for nature
The natural world is filled with living things. Living things start out weak and small and slowly grow strong and big. ① You are a living thing. Each of your classmates is a living thing. Flowers, grass and trees are living things, too. Bees, ants, doves, dogs and cats—these are all living things.

All living things need food and water to grow. Think about yourself. When you are hungry, you need to eat. You eat fruit, vegetables, meat and fish. They can help you grow big and strong. You drink water when you are thirsty. Now think about a tree. When a tree is hungry, it gets food from the soil. Trees drink water, too.
We are different in some ways, but all living things are connected. We all live on the same planet, and we depend on each other. If we pollute the rivers and oceans, fish may get sick or even die. ② Some birds live off fish. ③ If the birds eat the sick or dead fish, they may die off. Nature is a balance between all the living things on the planet. If one species dies off, then another species may die off, followed by another, and another. . .
We should respect the earth and all the living things on it. ④
