Essay on the topic of ecological pollution in 205o 400 words

Cherish resources and protect the earth.

Hello uncles and aunts of the neighborhood committee:

The earth allows us to live, let's protect. The earth is our home, and we are the little masters of the earth. Who doesn't want to make our home a better and more beautiful place?

At this time, the uncles and aunts who sell fruits, snacks, and vegetables set up stalls in various places and wait until the evening to close the stalls and leave, but they do not see the garbage they discarded everywhere around them, and in a few days, the garbage stinks on the ground, flies and mosquitoes are flying around, so that passers-by have to cover their noses and walk quickly. Have you ever thought that it is you who litter like this, adding a little dirt to our beautiful home? Therefore, I hope that the uncles and aunts of the neighborhood committee will let those vendors who set up small stalls take away their garbage when they leave, so that they can learn to take care of our beautiful homes

1. Pedestrians are requested to consciously take care of flowers and trees in parks, roadsides and other public places.

2. Take care of the grass and trees around you, and take care of the flowers and plants.

3. I hope that there will be more activities of planting trees and flowers in the society, and I hope that everyone will actively participate.

Every citizen who lives on the earth, let us work together to make our earth more beautiful and lovely, make the environment we live in better, and everyone strives to be the little guardian of the earth.

Friend, when you are living a happy and peaceful life, have you ever thought that our living environment is deteriorating step by step? When you clean your beautiful yard, have you ever thought about the white garbage that can be found everywhere around us? When you are fully enjoying the warm spring sunshine, have you ever thought that the sky over Antarctica has lost the protection of the ozone layer?

Once upon a time, the sky was so blue, the rivers were so clear, the forests were so dense, and while the natural environment gave us the enjoyment of beauty, human beings were also asking for things that they did not deserve from nature... …

In 1998, the Yangtze River, Nenjiang River, Songhua River and other great rivers flowing through the land of China hid the gentle and beautiful smiles of the past, revealing a fierce and terrifying hideousness. The raging torrential rain swept across the south and north of China, and everywhere the torrential rain went, the rivers and lakes swelled and the river ditches overflowed. The roaring river swept up flood peaks again and again, swallowing up villages, fertile fields, cities and counties, factories, and schools.

The raging flood is like a merciless devil's claw, tens of millions of acres of fertile land have been flooded, and millions of people have lost their homes. The mighty river is creating dangers big and small every day. The violent bake demon brews dangers big and small.

The violent devil brews tragedies big and small. Only by giving water a home and giving all living beings a home, will human beings have their own homes, and human beings will have their own homes; Only by giving water a way to live and all living beings a way to live can human beings survive and develop.

If ancient science has not yet developed, and the people of the earth have certain limitations in their understanding of ecology, and have done stupid things that only care about the present and ignore the long-term, then what about modern people? In the 30 years from 1950 to 1980, more than half of the world's forests were destroyed, with half of Africa's forests becoming barren. Green vegetation is the "quilt of life" given by nature to human beings.

However, after the world entered the 20th century 50 years, the green environment on which people and animals depend for survival has been destroyed, the green vegetation is declining, the global soil loss is now increasing to 25.4 billion tons per year, and the desertified soil is expanding rapidly at a rate of 5-70,000 square kilometers per year.

The earth is becoming more and more crowded, and with it, environmental pollution is changing day by day, and resources are becoming scarce. In the pursuit of happiness, people have to look back at the relationship between man and nature, and sign a covenant with nature for sustainable development. All of this reminds us that:

Environmental protection is imminent!

We live on the same land, we share a common homeland and protect our environment. The earth is looking forward to green, the rivers are looking forward to green, the waterfowl are looking forward to green, and the flowers are looking forward to green. Dripping water into a river, accumulating soil into a mountain, protecting the environment, starting from you and me.

Awaken the "green heart" and implement the "green plan". Carry out "green action", strive to be a "green builder, and create a "green new century"!

When you wake up in the morning, do you notice that the first thing you hear is not the chirping of birds, but the shrill horn of a car? When you go shopping on the street, do you ever find that the wind blows with sand and you can't open your eyes? When you go out in the wilderness, do you find white plastic bags hanging from the trees?

When you look at the scenery, do you notice that the sky is no longer blue, the water is no longer clear, the trees are no longer green, the wind is no longer soft, and even the sun is so dazzling? These remind people all the time that "it is time to protect the environment".

The earth is the mother of humanity, and we should protect her. Have you ever thought that if you plant more trees and drive fewer cars, sandstorms will no longer appear and the sky will no longer be dark? Have you ever thought that if you don't bring one more and use one less plastic bag, you will lose an ugly "hat" on the tree? Humans, have you ever thought that as long as the chimneys do not emit jet-black gases from the air, the lovely sky will become blue, the ozone layer will gradually thicken, and the sun will no longer be dazzling?

Have you ever thought about this?

No, you haven't thought about it, and if you did, it wouldn't be a hole in the ozone layer; It won't be a kind of extinction of a creature; Won't let the clear creek poop be dark.

1. Use less plastic bags and more environmentally friendly cloth bags;

2. Try to walk, cycle to school or take the bus to save gasoline resources;

3. Turn off the lights at hand and don't waste electricity;

4. Use spare time to plant trees and protect the environment;

5. Reuse waste products**.

It is everyone's responsibility to protect and protect the environment.

Finally, I'll end my essay with the slogan: "There's a lot more we can do."

Protecting the Planet Essay.

Humanity has only one earth, which is a resource for survival. The earth is like our home, so we should protect it instead of destroying it. In recent years, the earth's environment has become worse and worse, large areas of forests have been cut down, green green mountains have been excavated, beautiful prairies have become deserts, and clear rivers have become stinky ditches.

There are fewer forests, the green hills are bald, the grasslands are barren, the rivers are black, the environment in which people live has deteriorated, and the air they breathe has deteriorate......dAs a result, there are more diseases in human beings.

Now there are fewer and fewer forests, and that's because people are constantly cutting down trees, so there are fewer and fewer trees, so we can't breathe more fresh air, and we will suffer from SARS, avian flu and other diseases, so that our physical fitness declines, so that these viruses can easily enter our bodies. If you keep cutting down trees, when a typhoon comes, you won't be able to resist the typhoon, and won't we humans still suffer?

Over the past few years, the number of factories has increased, and so has the amount of sewage discharged, often discharged into nearby small rivers, making the previously crystal clear water stink. People often litter the bottles of finished drinks, and white garbage can be seen everywhere. You say, would you feel good to live in such an environment?

Let's start with water conservation, and everyone may say that wasting a few drops of water won't damage the environment. Everyone in the world wastes a few drops of water, if everyone wastes three drops of water, then 5 billion people in the world will waste 15 billion drops of water, and if this water is given to those arid places, how many people can be saved! Saving water is everyone's responsibility, so we should all save every drop of water and not waste every drop of water.

Otherwise, the last drop of water on earth will be human tears!

Human beings have only one home - the earth, which is the place where human beings live, and we must protect it.

She worked hard to nurture us and make us thrive. However, today, when I just fell asleep, there was always some crackling sound of burning straw, which made me toss and turn. When the window is open to breathe, there will be a puff of smoke wafting in, very choking, I really want to run out and scold them, anger fills every cell of me, and then I think, who will listen to me as a child?

Maybe some people think that I have something wrong with my brain, or maybe some people will say, "Child, where to stay where it is cool, what do you know?" We don't burn straw, so where do we put it? "If that's what they're going to do, what should I do?

I even think they are vulgar and they don't know how much pollution burning straw can bring to the atmosphere.

When I go to the wheat field behind, I always see the dazzling fire greedily devouring the straw, and the stalk that has been burned to black, with clouds of smoke, goes straight to the eyes of people, "tear-jerking", maybe this is the revenge of the straw to human beings!

When we let the fire eat the straw unscrupulously, have we ever wondered what will happen to future generations? Shouldn't we live for the sake of future generations? The act of burning straw is selfish, it is shameful, and if we continue this pathetic act, Mother Earth will leave us children behind.

I seemed to see a blood-red moon hanging in the sky, there was not a single star in the vast sky, and the dazzling blood-red was approaching people! It's coming! That heralded the coming ...... the end of humanity

The Earth of 2050 As time passes, the Earth of 2050 is in front of us. At that time, the earth was no longer what it used to be, it was no longer full of garbage, no longer there were no flowers and trees, and no longer the earth was polluted with air everywhere. It is a completely changed earth, the air is so fresh, the environment is so elegant, it is really applauding and admiring! The earth in 2050 is a world of green trees and birds.

Trees are everywhere, which makes our ecological environment much better. This is because since the first advocated "more trees, less cutting" activities, now we are surrounded by birds and flowers, the air is very fresh, so that our ecological environment is balanced. We should get moving, plant more trees, and let our Mother Earth's "hair" grow more.

The earth in 2050 is a "demon" that has not been devoured by pollution. In the past, the spread of water pollution and air pollution was very fast, because we human beings ignored water pollution and air pollution, which stained the water we drank black, made the air extremely turbid, and made us humans unable to drink or breathe; However, by 2050, every city and every corner will have sewage treatment stations and air treatment stations to clear the polluted water and clear the turbid air, so that we humans can once again drink cool and delicious water and breathe in clean air. Let our homes no longer be polluted, and do not let the demon of "pollution" stain the "face" of our lovely earth again, the earth in 2050 is an earth with an elegant environment.

The environment is elegant, and there is no longer stinky garbage on the ground; On the streets, cars are powered by odorless, odorless and colorless fuels; The environment is not polluted by the air again, so that the home is elegant and fresh, and our ecological environment is balanced, which is the life we dream of! The Earth in 2050 is not what it used to be. It is a ...... without air pollution and water pollutionThe earth, the homeland is no longer invaded by "pollution", and people will not be tormented by the problem of "pollution"!

I believe that the earth with a balanced ecology and an elegant environment will take off in the future! Let's take action! Let us take the earth in 2050 as an example of the new century, the beginning of the new century, and let us stretch out our hands to build our homeland better!

At the beginning, you can start with a preface to start with a lost child, the deterioration of the environment has led to disease, and then meet a caring space warrior, and then use their experience to describe the state of the earth in 2050, technology has developed to the point where it is unimaginable, and people's lives are very different, rich people have spent a lot of money to flee the earth, and go to other planets to survive, but can it really survive better over there... People with no money are still in dire straits, the spread of the plague, the panic of the virus, the emergence of aliens, and everyone is born with a gas mask! The world is in chaos!

As a result, the first to start the Earth Survival Plan, can advanced science cope with and change these... The extreme development of science and technology has led to the further destruction of the environment, and people are so vulnerable to nature...
