An essay on the theme of protecting the environment and cherishing the land

A proposal is a call-to-action letter written to initiate an initiative, a public proposal, and a special letter.

Format] The proposal is generally composed of five parts: title, title, body, ending, and paragraph.

a) Title. The title of the proposal is generally composed of the name of the language alone, that is, the three words "proposal" are written in a larger font in the middle of the first line.

In addition, the title could consist of a combination of the content of the initiative and the title of the language. For example, "Proposal for the transfer of the body to the medical profession".

b) Salutation. The title of the proposal can be appropriately chosen according to the target of the initiative. For example, "the vast number of young friends:", the vast number of women compatriots:", etc. Some proposals can also be pointed out in the text instead of being called.

1.The background, reason, and purpose of writing the proposal.

Only by clearly explaining the reasons for the initiative's activities, as well as the various background facts at the time, and stating the purpose of the initiative, will people understand and be convinced, and will they take action consciously. If these factors are not explained clearly, it will be inexplicable and difficult to respond.

2.Specify the specific content and requirements of the initiative.

This is the main part of the text. The content of the initiative must be concrete. What kind of activities are carried out, what are the things to do, what are the specific requirements, and what are its values and significance, all need to be written one by one.

The specific content of the initiative is generally listed in separate sections, so that it is often written clearly and clearly at a glance.

iv) Ending. Conclude by expressing the determination and hope of the proponent, or by writing some kind of proposal. Proposals generally do not end with a word of respect or wishes.

Proposal.

Teachers and students of the school: This year, China's Yangtze River basin and Nenjiang River basin have experienced catastrophic floods since the founding of the People's Republic of China, causing huge property losses to the country and bringing great inconvenience to the lives of the people in the disaster areas.

In the big socialist family, "when one side is in trouble, all sides will support" is the embodiment of the communist spirit. We encourage all teachers and students to donate money and materials to help the people in the disaster area tide over the difficulties. "A penny, a piece of clothing", money and things are valuable, love is priceless, and everyone's support is valuable.

Student union. YYYYYYYYYYYYYYYYY

In life, work and study, everyone has written essays, and they must be familiar with all kinds of essays, and the essays must be focused on the theme, and make in-depth elaborations around the same theme. Don't have a clue when it comes to writing an essay? The following is my collection of soil protection essays, welcome to read, I hope you can enjoy it.

The land is the foundation of human food. Environmental pollution caused by highly developed industry also often brings disasters to the land.

Soil pollution mainly refers to the phenomenon that the content of certain harmful substances in the soil greatly exceeds the normal content, and the land itself cannot eliminate the impact of these harmful substances. Severe land pollution can lead to reduced growth and development of crops and even wilting and death. The consequences of environmental pollution can be detected in time, and more soil pollution has no obvious manifestations, but it reduces the quality of agricultural products, especially through the enrichment of crops on harmful crops, which secretly endangers livestock and human health, and must arouse a high degree of vigilance.

Soil pollution is mainly caused by domestic wastewater and industrial wastewater, waste gas, waste residue, chemical fertilizers and pesticides. Modern agriculture uses a large number of chemical fertilizers, resulting in a large number of inorganic substances such as nitrate, sulfate, chloride and other inorganic substances remaining in the soil, they destroy the physical and chemical properties of the soil, make the soil compacted and salinized, and thus reduce crop yields. The use of pesticides causes organic matter such as polycyclic aromatic hydrocarbons (PAHs) and polybiphenyls to settle in the soil, poisoning animals and humans.

Atmospheric soot and harmful substances such as SO2, nitrogen oxides, and radioactive dust naturally settle in the soil with rain and snow, causing soil damage. Among the soil environmental pollution, heavy metals cause the greatest harm, and chromium, manganese, nickel, etc. can also cause cancer in different parts of the human body. Plants can also be damaged by high levels of metals in the soil.

According to experiments, wheat dies when it contains 20 milligrams of copper per kilogram of soil; Up to 250 mg, the rice will also die. More than 50 milligrams of zinc per kilogram of soil can affect crop growth.

Once soil is contaminated, its effects are difficult to eliminate. Organic pesticides decompose very slowly, heavy metals do not decompose at all, and even if the polluted land does not continue to be polluted, it still contains high substances within three to five years and can be enriched through the food chain to endanger humans. So, contaminated.

The plants on the land are not only inedible, but also cannot be used as fodder or fertilizer. Here, I would like to offer some of my suggestions. First, reduce the use of harmful pesticides and use existing science and technology to develop harmless pesticides; second, the establishment of sewage treatment plants to centralize the treatment of industrial wastewater and domestic wastewater; Third, the classification and disposal of domestic waste; Fourth, every country should build many waste battery treatment plants.

Although an investment will be millions, tens of millions, or even hundreds of millions of yuan, its completion will benefit the earth a lot.

May our home, the earth, live forever in the vast universe.

Trees are the best gift from Mother Earth to people, but some people just don't cherish this precious gift, destroy it, destroy it. Yes: Like a man of wood, he goes to cut down trees every day.

One day, as always, he went to the forest to cut down trees, smoking cigarettes and cutting trees, regardless of the feelings of the trees, and did not know the consequences of indiscriminate felling of trees. Tomorrow? Day after tomorrow?

A woodpecker flew and landed on the head of the wooden man, pecking at his head and saying, "There must be worms and ...... in this piece of wood.""Yes, some people tend to only think about their own interests, only want to have more and more money, completely disregard others, their hearts and brains have been hollowed out by the "money" worm, and they have lost their human nature. Trees, what a gift, Mother Earth has no selfishness and gives everything she has to humanity.

But human beings do not know how to cherish it.

If the trees are gone, then there is no way to absorb carbon dioxide and release oxygen, then people will face the problem of difficulty breathing, a large amount of carbon dioxide will increase the temperature of the earth, and everything will not be able to survive; If there are no trees, human beings will face more natural disasters, sandstorms, mudslides ......This will be Mother Earth's punishment for us; If the trees are gone, the animals will be extinct, and without the animals, the humans will also be extinct......

Speaking of which, it has returned to human beings themselves, and the harm has been harmful to human beings themselves, who can blame this? Let's take action, there is only one earth, it cannot be cloned, it cannot be regenerated, it is our duty to protect Mother Earth, and we should not bear the infamy of unfilial children; Let's take action, from this moment on, plant more trees, plant more trees, use less disposable wooden products, discourage those who cut down trees indiscriminately for monetary gain, and wake up those who are controlled by the big insect of "money"; Let's take action and protect the gift of Mother Earth!

Cherish resources and protect the environment.

With the rapid progress of the times, human life is getting better and better. However, there are more and more phenomena such as arbitrary exploitation, destruction, pollution, and waste.

Now, the faucet keeps flowing clear tap water, but the water people don't know where to go; The lights and TV are on, and the room is empty for a long time; The notebook was thrown in the trash, but only a few pages ......Such a phenomenon can be seen.

Therefore, we should take action and advocate: cherish resources and protect the environment!

There are many things we can do, such as:

1 Conserve water. In order to cherish water resources, do not let the faucet run empty, and shorten the shower time; installation of water-saving faucets; Use a water-saving flush toilet.

2 Save electricity, use as little electrical appliances as possible, and turn off the lights at will. Close the refrigerator door at all times; use of energy-efficient lamps; Purchase.
