Essay on whether the land in your hometown is protected or destroyed 500 words

Don't you feel sick when you walk on a wide road, admiring the green trees and red flowers next to you, and suddenly smell the stench of sewage coming from your nose? When you are walking on the golden sand, the sea breeze is blowing on you, and you are in a very good mood, and suddenly a plastic bag flies in your face, don't you feel disappointed? Don't you feel irritated when you hear the noise of a nearby construction site while you are studying?

The earth belongs to everyone, and environmental protection depends on everyone. If we want to live comfortably and have a beautiful living environment, we have to take care of every grass and tree in nature.

In fruits, vegetables, crops, flowers, grasses, fields, rivers, ......Water is everywhere and never stops. If a person does not drink water for three days, he will die. You can see how important water is.

At present, only 3% of the earth's fresh water is the earth's water source, and of this 3%, only most of the earth's freshwater is polluted, so it is an urgent task for mankind to protect water resources. Students, let's take action! When you see the water from the faucet rushing, you step forward and twist it tightly with your hands; When strolling along the river, don't throw the garbage in your hand into the river; Don't waste the water used to wash clothes, use it to flush the toilet, and try to achieve the ...... of "one water for multiple purposes".I believe that through our efforts, we will turn the desert into a lovely oasis; It will make the grass fatter and the trees greener; It will make the water in the river flow happily, and the water in the river will jump ...... happily

By the way, the area of forests is also decreasing, about 11 million hectares of forest area is lost every year in the world, and the decline of forest area is an important reason for the expansion of desert area. The loss of forests has made the climate more harsh, with less rain and more severe droughts. The destruction of grasslands and arable land has put one-third of the planet's land under serious threat of desertification.

All kinds of harmful gases have been discharged into the sky, enveloping our beautiful earth, so that the ozone layer in the polar regions has lost 20% to 30%, and the ozone layer in the Antarctic has lost more than 50%. Without the protection of the ozone layer, the sun's ultraviolet rays will drive straight into the sun, causing harm to human health. Let's talk about the penguins in Antarctica!

As we all know, Antarctica is a relatively cold place, and there are many cute penguins living there. However, due to the lack of care for the environment and littering, the ecological environment of Antarctica has been incredibly damaged. The various penguins that live carefree in Antarctica are also threatened by their lives.

Because of human inadvertence and uncontrolled destruction, only cute penguins in Antarctica are gradually facing extinction. Yes! Human beings have savagely destroyed the natural environment and cut down forests, resulting in a shrinking habitat for wild animals and leaving many wild animals homeless.

According to the International Union for the Conservation of Nature and Natural Resources, 110 species of mammals and 139 species of birds have become extinct in the world, more than 1,000 species of vertebrates are in danger of extinction, and more than 25,000 species of plants are in danger.

Sorry, I'm looking for it too. (The land of the hometown).

Water Conservation Cherish water resources.

There's a famous saying that as you save, you get

Water is the source of life, as the saying goes"A person may go a day without food, but not a day without water"Human life is inseparable from water, and water is an indispensable and important resource in human life.

According to the data, the freshwater resources on the earth that can be directly used by human beings account for only 0.3 percent of the earth's white water. The vast majority of the planet is severely short of water, many treesVillages and fields are not swallowed by desert, and the desert area is gradually expanding.

The reduction of freshwater resources has seriously affected the economic construction of mankind and threatened the survival of mankind. Saving water and protecting water resources has aroused great attention from all mankind. Build a water source with abundant water

The beautiful home of the beautiful mountains and rivers is our wish

However, the waste of water resources is quite serious in our livesFrom the data we surveyed, it is clear that in our real life, around us, the waste of water is alarming. .

Let's talk about our school, we have noticed that sometimes the faucet in the school building is broken, and the water is running non-stop. Some faucets are often dripping out of the water drop by drop, these do not know how much water is wasted, many families seem to be very water-saving, but in fact they are wasting water resources. In some homes, water from the faucets in the kitchen and bathroom is dripping into the tanks and buckets all day long, but the water from the tanks and buckets is constantly flowing out of the drain.

Some families put some of the water that is completely usable, like the water for washing vegetables and washing the face, directly into the sewer, and look at the wasted water, if it drip out drop by drop throughout the year, it will drip about a ton of water. As you can imagine, the water that is wasted in our lives is really incalculable, and if you want to calculate it carefully, the result will definitely make you stunned!

While we waste water, we are also polluting our water sources Some cities and towns discharge domestic polluted water and industrial wastewater directly into rivers, and some throw garbage and dead livestock directly into rivers, so that the river water can no longer provide convenience for human beings.

Everyone saves water, cherishes and protects water resources, and gives us a green tree. Flowers. The river is clearLet's have a beautiful living environment for fish!

It's okay, it

Hahahehe.

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"!

The fierce "man-rat war" is still fresh in people's memories.

It was summer vacation four years ago, and I was walking downstairs to eat. Suddenly, at the corner of the stairs, a gray figure flashed by. Timid, I was stunned for a moment and stopped.

Puzzled eyes stared at the corner, trying to see what it was. About twenty seconds later, as I expected, the gray shadow appeared from the corner of the wall again. I took a step ahead of it and blocked its path with my foot.

Grey paused, glanced up at me, and quickly "went back the way he came" and ran back into the corner. With just one glance, I judged that it was my "natural enemy" - rats! I stared at the corner of the wall where the rat appeared for a few minutes, and then suddenly my eyes widened and I screamed at the top of my voice

Wow! There are rats! Suddenly, the house shook three times with my high-decibel voice.

Dad, there's a mouse, catch it! Seeing that I was about to cry, my father quickly comforted me: "Don't cry, don't cry!"

Daddy catch, catch it now! I held back my tears. This is the beginning of the man-rat war.

Round 1: Dad holds a slipper high and stands with me at the mouth of the rat hole. A few minutes later, when Dad lifted his slippers until his hands were sore, and just as he happened to put them down to rest, the mouse seized the opportunity to rush out.

Dad, there! "Listen to my command, and Dad immediately threw his slippers at the rat. "Here!

There! Oops, there! It's got here!

Dad in only one slipper** can run past the agile little mouse. Eventually, the rat returned to the burrow, and Dad was so tired and out of breath that he didn't touch a single hair of the mouse. The first round is over, and the rat wins!

The second round of the man-rat war: I grabbed a handful of rice and put it at the mouth of the rat hole, and sang affectionately into the rat hole: "Little mouse, open the door, come out quickly."

Daddy was embarrassed. Half a day later, I sang until my throat was hoarse and the mouse didn't move. The second round is over, and humanity has been defeated!

In the end, no matter how hard we grind, the rats just don't come out. It was still my father's strength to buy a pack of rat poison and put it at the mouth of the rat hole with food. Three days later, the rat carcass appeared as scheduled. In the final round, the humans were victorious.

Human beings are so selfish and so arbitrarily trampling on the resources accumulated by Mother Earth for thousands of years. I hear Mother Earth crying!

Last year, my parents took me to go to other places, and when we arrived at the destination, we just got off the bus, and I smelled a stench, it turned out that the stench emitted by the small river was not recognized as a river. The people there told us that the river used to be very clear, but when the construction team came here to develop it, the river became like this.

When I heard this, I couldn't help but feel angry in my heart: why can humans destroy nature for their own benefit! Don't those people love nature?

The next day, my parents and I went to the mountains to play, but there was garbage everywhere, and the carcasses of those small animals, it was really too much! I saw another uncle drinking, and when he finished drinking a bottle of wine, he threw it away, and when I saw it, I hurriedly went up to stop it, but he yelled at me: "Mind your!

A little ghost is going to take care of me, you're dizzy! At that moment several uncles and aunts who were watching also came and advised the uncle, who, blushing, picked up the empty bottle and threw it into the trash.

I appeal to the blue sky: Wake up, O human beings! Do you really want to leave our Mother Earth in ruins? We have only one home – Earth!

I love Mother Earth.

When I first saw the sea, it was still very small, and I was amazed by the vastness of the sea, and a concept naturally arose in my mind: water is endless, inexhaustible, and inexhaustible.

Indeed, in people's impressions, water is everywhere and serves people's production and life. It is the blood of industry, the lifeblood of agriculture, and the most indispensable assistant in life. In short, water is a precious treasure that we rely on for survival, and according to the survey, the earth we live in also has an alias called "water ball", as the name suggests, our earth is full of water. But 97 percent of this water is seawater, and half of it is in the inland sea and salt lakes.

The root of fresh water is rain and dew, and only 10,000 cubic meters of water fall to the land every 49 years, and 2 3 of them are transpired by plants or evaporated by the ground, and only 1 3, that is, 10,000 cubic meters of water can be used by human beings.

Is this little water enough for us? The answer is no.

In this case, why do people always turn a blind eye when they see the tap water flowing "rattling" and are reluctant to take a step forward and turn off the tap? Why is it that when some people throw garbage into rivers, seas and lakes, they can't imagine how polluted the water is? Why don't people feel sorry when industrial sewage flows into rivers, seas and lakes and sees the originally clear water turn into sewage?

Why when...

In fact, human beings are now slow to commit suicide, they do not regret polluting and wasting water resources, but how precious water is! If we don't cherish water now, water will be as precious as oil in the future.

Therefore, we need to do a good job in water recycling. Using a natural desalination device to desalinate seawater is environmentally friendly and cost-effective. The problem of water source is solved, how to use it?

People should invent more water-saving products such as "electrolyzed water molecular washing machine", "electrolyzed water molecular washing machine" uses the principle of electrolysis of water molecules, so that the oxygen atoms in the water molecules absorb the booty in the clothes, and the electrolyzed hydrogen atoms can be used as fuel for environmentally friendly cars, which does not damage the clothing fibers, but also provides power energy for the car, and also does its best for the cause of environmental protection, why not?

Yes! Wake up! If we don't cherish water resources, the last drop of water that will fall on the earth in the future will be our own tears.
