When night falls; When the city is brightly lit and neon flashes; When people were intoxicated with this beautiful night, someone made a dissatisfied voice: "It's dark, please turn off the lights!" " "

At 20: 30-2 1: 30 on March 26th, please turn off the lights at home! Maybe you will say, "This is just to save energy and reduce emissions!" To this, my answer is: "Not only that."

Why? Astronomers said: "The invention of electric light did bring us convenience, but it caused light pollution because people used too much electricity. Now, our night sky is being swallowed up by light pollution, which makes astronomical observation difficult. "

Animals are the most implicated. The zoologist said, "Who is most harmed by light pollution? It must be an animal! Light is a powerful biological force. For many creatures, light attracts them like a magnet. Since humans lit up the sky with lights, many Nocturnal Animals have become more and more confused. Little turtles will climb into the sea after they are born. Because people climbed in the wrong direction with the lights on. Under the action of artificial light, the biological clocks of thrush and nightingale are destroyed by light, and they "start their nerves" to sing in the middle of the night. Some birds that move at night run into brightly lit buildings because they can't see the glass clearly ... "

Earth Hour, I hope everyone will turn off the lights in the dark!

Environmental protection is a word deeply rooted in the hearts of people all over the world. What is environmental protection? Environmental protection is a concept, an idea. Environmental protection is an action that everyone needs to carry out. Environmental protection is a virtue, a virtue that has been passed down to this day and needs to be passed down forever.

Environmental protection is a basic national policy of our country. At present, the deterioration of ecological environment not only causes serious economic losses, but also threatens the survival of mankind.

Environmental protection, a timeless word, a word passed down from mouth to mouth.

Environmental protection, I'm trying. Now the forest area on the earth is decreasing in a large area, and the green on the earth is disappearing one by one, replaced by naked yellow, which has become memories and nostalgia, and memories have become forgetfulness. The sound of the saw didn't stop, nor did the cries of the trees disappear. A large number of disposable chopsticks were transported into restaurants in batches, large and small, and then cruelly abandoned. The whole incident only took a short meal. Why don't we solve this problem in a more rational way? The idea of Koreans making toothpicks from starch and potatoes inspired me. Toothpicks can be made of starch, so can chopsticks. You can learn from the Korean method, mix starch and water in a certain proportion, and then put it in the oven to dry. In this way, a new pair of environmental protection chopsticks is ready. Of course, making chopsticks requires higher technology, because chopsticks must be resistant to high temperature and soaking. So the mixing ratio of starch and water is very important, and baking is also the key.

This made me realize that seemingly insignificant items can also create miracles through technology, bold creativity and human hands. Below I combine my own life and make bold guesses, which I believe can be realized in the near future.

Napkins are the expression of modern people's love for cleanliness. Of course, napkins have also become the garbage of life. Can they be recycled? In addition to the traditional handkerchief, a new type of napkin can be produced to replace it, which is temporarily called circulating napkin. The appearance of this napkin is no different from other napkins, except that it has many pores. When people wipe off a big piece of dust from the floor, they always wrap the dust in napkins and throw it into the trash can. This not only wastes paper, but also inevitably leaves some dust on the way. Vacuum napkins are different. Its pores can suck dust in and are divided into two categories. One kind is useful dust; There is also useless dust. After that, the useless dust will be discharged, and the useful dust will be left for use slowly. This can not only collect certain resources, but also recycle napkins. Why not?

Security window is installed in almost every household now, in order to prevent thieves from climbing in through the window. Can we develop a new security window with more functions and call it "Multifunctional security window" for the time being? This "multifunctional security window" can not only effectively prevent thieves from climbing in through the window; But also can absorb noise. There is a mini sound absorber inside, which can absorb the noise from cars, speakers and so on. It also provides a peaceful and quiet environment for the room. If you like listening to music, you can instantly turn the sucked noise into your favorite wonderful music and play it. It can also prevent dust. A miniature high-power vacuum cleaner is installed on the safety window to absorb dust and provide a clean room. I believe that such a "multi-functional security window" will be loved by everyone.

Environmental protection is endless. I hope everyone can take action to create a beautiful and harmonious living environment.

World Earth Day Composition 3

"Boo-hoo, Boo-hoo" There was a cry from the distant galaxy. Who cried so sadly? It turns out that Mother Earth, who has a great responsibility in the Milky Way, cried so sadly.

This cry happened to be heard by Grandpa Sun who was walking. Grandpa Sun goes to talk to Mother Earth. But when I first saw Mother Earth, I was blindsided: Mother Earth's shiny black hair has now turned into white hair, and her gauze-covered body was originally blue and white, but now it is beyond recognition. What's more frightening is that her body has begun to turn black and stink. Grandfather Sun was even more shocked when Mother Earth showed her medical records. It says: August 18-chronic bronchitis, September 30-gastric ulcer. ...

Grandpa Sun asked Mother Earth with concern: "Mother Earth, don't cry, are other planets bullying you?" If so, as the most prestigious person in the galaxy, I will definitely take responsibility and talk about them so that they will not bully you again! "

Mother Earth shook her head and sobbed and said, "No ... it's all the good deeds of those people who were born in happiness and didn't know it." They hacked my precious resources indiscriminately. Initially, these forest resources and atmospheric resources ... can be continuously regenerated, but due to their uncontrolled exploitation, most forests are destroyed and the balance of soil and water cannot be maintained, leading to desertification and rocky desertification in most areas. " Mother Earth paused for a moment, then said, "How many appeals and suggestions have been made by those humans to protect nature, but how many people have really done it?" Their reckless abuse of chemicals has also caused a series of ecological disasters and brought serious threats to themselves. "

Grandpa sun then asked, "so what happened to your little animals?" Are you happy? "

This time, Mother Earth cried even more sadly and said sadly, "99% of my animals are extinct, and some animals will be on the verge of extinction. In the near future, it is estimated that they can only be seen on the painter's paper. Those humans secretly kill animals, sell animals, or eat animals. The ultimate goal is just to enjoy them. They humans don't know that animals are also life and have feelings. "

After listening to Mother Earth's complaint, Father Sun couldn't help sighing: "The earth is too fragile, so you humans should wake up."
