What to write on the placard about protecting trees and how to do it

Cao'er, life is wonderful because of you. Flower, the world is beautiful because of you

Be green and environmentally friendly, starting from me

Protecting the environment is protecting life

Only with a fresh environment can you have a clear mind

To protect the environment, start by picking up a scrap of paper around you

Stretch out your hand, Pick up every scrap of paper

Green is human life

The earth is my home, we must love it

Keep the beauty of flowers and reflect your beauty

Be green and environmentally friendly, start with me

Protect green, create green

Bloom with flowers and grow with small trees

< p>Planting a tree may become a forest; saving a drop of water may become an oasis

Green is the source of life

Care for flowers, plants and trees, eliminate white pollution, and let Mother Earth No more crying

One more piece of green, one more piece of peace

Leave me a piece of green and return a piece of love to you

The more green the world has, the more it will Wonderful

Protecting the mother river is protecting the spring of life

The grass warns, be gentle under your feet

Give a piece of love and protect the flowers, plants and trees

< p>If you lose a piece of green, you will lose a piece of fresh air

The city is as green as the sea, and there is less pollution in the world

Green is the root of life, and green life depends on People care

Protect the green in your eyes and keep the red in your heart

The green environment makes you feel relaxed and happy<

Let us join hands and plant the seeds of life together

Adding green to the school is to add luster to the school

One more piece of green, one more quiet beauty

Green is a breeze that refreshes you

Stretch out your hands and spread green hope

Green lasts forever, life is eternal

Green needs human care, and human beings need green vitality

The grass is luxuriant, but it is a pity to trample on it

The more green the world has, the more wonderful it will be

Green environment beautifies life

Green is life Seeds

Mother Earth is tired, humans need to wake up

Green, the note of life

Only when you have green, you have a home. Protecting green means protecting your home

The sun, green, and water... are just like human organs, and they are indispensable. The sun, green, and water are indispensable... just like a big family, a person is just a "member"

Looking at the grass as eyes, I grew up with the grass

Patches of green, every heart

New green, new school, new Olympic Games

A clear fresh green brings the awakening of all things; a faint floral fragrance brings beauty to the world

Without green, spring will no longer come. Choose your own.
