Please write a speech on the topic There is only one Earth .

We only have one Earth.

Once upon a time, there was a beautiful legend. Legend has it that a great mother, dressed in a white water coat, wore a green straw hat, and held a light blue umbrella, a faint blue, a faint existence.

The mother had three sons, the sky, the sea, and the land. She worked hard to nurture them and watched them grow up day by day. The sons were deeply grateful to their mother, and the sky reflected itself in the ocean, turning their mother's watercoat blue; Flowers and trees grow on the land, creating green mountains and green waters, making my mother's straw hat even more beautiful.

The mother was so happy that she gave life on land and sea, added white clouds to the blue sky, and lived a peaceful life with her sons.

Time flies, and in the blink of an eye, the mother's fourth son, the human race, is born. His mother blessed him with wisdom and creativity, nurtured him with care, and lifted him up with hope.

The sky said to humans: "Brother, I am willing to let you soar into the blue sky." ”

The ocean said to humans, "Brother, I would like to take you on a journey around the world." ”

The land said to the humans, "Brother, I am willing to be trampled under your feet." ”

Finally one day, humanity feels like he's grown up. He is no longer satisfied with everything that others give, and he is no longer resigned to his position.

So, he used the wisdom and creativity given to him by his mother to desperately strengthen himself. In order to be powerful, he emitted harmful substances into the sky, causing black holes in the atmosphere; He punished the pollution of the oceans severely, and there were large red tides; He also caused the land to be eroded and made into a thousand ravines.

Mother was devastated, not because her blue coat had turned black, not because her straw hat had turned brown, not because her umbrella had turned to pieces, but because humans had pointed the finger at their own brother for their own sake. In order to get their own things, human beings brutally pierced the sky, pierced the ocean, and shattered the land, and pointed the finger at the mother, the deep well where the nuclear waste was stored, piercing the mother's heart like a needle. The mother became frail and sickly.

She couldn't stand the blow anymore.

The sky, the sea, and the land are finally outraged, and they have taken revenge on humanity in their own way. In the face of the terrified human beings, they only said one word: "We have only one mother, and for the sake of our mother, we have no choice but to destroy you."

After that, tsunamis, hail, **, and ...... hit humans

A long, long time later, there was a beautiful legend of a great mother who wore an azure water coat ......

The earth is a common home for all mankind. On this only earth, space is finite and resources are finite. For today, but also for tomorrow; For oneself, and for one's descendants; Let's all take care of our home and our planet!

Because we only have one Earth!

The title of my talk today is: We Only Have One Earth.

The beautiful Earth is the most dazzling planet in the universe. She is the mother of humanity and the cradle of life. She dedicates all her wealth with motherly generosity and selflessness, so that we have a past and a happy and comfortable life.

But now Mother Earth has lost its former glory in order to take care of us! "Our earth is so lovely, and at the same time too easily broken! This is the exclamation of astronauts when they travel to space and see the earth.

The earth is small. It is a planet with a radius of just over 63 million kilometers. In the starry universe, the earth is like a flat boat.

It's only so big that it won't grow again.

Protect the planet and love our homeland.

When human beings left the earth for the first time and looked at their hometown in space, they were surprised to find that among the cosmic stars known at present, only the earth, the home of our human beings, is a blue planet. The lush vegetation, the green trees, the birds and the fresh air are the homes we dream of. The earth is the only place where human beings live, and if human beings want to live and work on the earth in peace and contentment, they must take care of the earth, protect the environment, and maintain ecological balance.

The sky is blue, the wilderness is vast, the wind blows the grass and sees the cattle and sheep" What a beautiful poem! All of a sudden, it brought us to the reverie of the natural scenery, so beautiful and harmonious, so vibrant, but now, human beings are transforming nature at a rapid speed, a piece of forest falls, a piece of green disappears, a high-rise building is built, a piece of sewage flows out, our living environment has been seriously damaged, the atmosphere, water, land is seriously polluted, and the ecological balance of nature has been greatly affected.

Many of the creatures that were once common on the planet are now gone, and the wanton destruction of nature by humans will not only cause species extinction, but also cause climate change. Acid rain, global warming, rising sea levels, melting ice floes, collapsing ice shelves, sandstorms, ......These natural disasters are all human"A masterpiece".Do you know what the cost of 1 degree of global warming will be?

After experimental demonstration, American scientists have come to an astonishing conclusion: a 1 degree increase in the average temperature of the earth will reduce the yield of crops by a large amount; If the polar region rises by 2 degrees, melting water will flood 90% of the earth's land; If it rises by 3 degrees, all ecosystems on the planet will collapse.

So, from now on, we should do our best to close the environmental loopholes. We can start from the little things around us, such as trying not to use disposable chopsticks, planting more trees, and caring for every grass and tree around us; To save water and electricity, the faucet should be closed tightly after use, and the lights should be turned off in time after use. Don't litter waste batteries, plastic bottles, etc., pick up garbage when you see it, etc.

No accumulation of steps, no thousands of miles; No matter what you do, you must start from me, from now on, from the little things around you. Protecting the environment is everyone's responsibility. Let's do it!

As long as we work hard, green will definitely surround us again!

Without the earth, there will be no human beings, without the earth there will be no flowers and grasses, we must cherish the earth's water sources, do not kill the life on the earth, we must rely on our hands to protect it, rely on our practical actions to protect him, remember this sentence: human beings have only one earth.

Come! Let's protect him, we have to learn to protect the environment!
