Electricity is something that every primary school student comes into contact with every day, and it is also an indispensable thing in our daily study and life, but now its consumption is amazing. Therefore, every move when using electricity should start with saving.
In China, power generation mainly depends on burning coal, and the coal on the earth is limited. According to the current consumption rate, the global coal will be consumed within 250 years. After that, we will have no coal for our future generations.
Saving electricity means saving coal and directly contributes to reducing air pollution. Because acid rain is formed by burning coal, it can strongly corrode buildings, acidify soil and water, lead to reduced grain production and death of plants, fish and shrimp. According to calculation, the annual economic losses caused by acid rain in southwest and south China alone amount to 654.38+0.4 billion yuan.
Saving electricity can slow down global warming. Because of the large amount of carbon dioxide emitted by coal burning, it blocks the heat from the ground to the outside of the sky like a cover, which has produced the greenhouse effect. If the earth's temperature rises, it will cause drought or flood and melt icebergs. If all the icebergs on the earth melt, countries and islands with lower altitudes will disappear.
Living today, we are bound to enter the next century. Many of them are vulnerable to global warming. 65,438+035,000 children in 65,438+092 schools in Germany vowed to reduce the harmful gases that cause the greenhouse effect in their communities by 65,438+00%. They put on energy-saving lamps, refused to use air conditioners, gave up cars and chose bicycles. After seven months of hard work, they achieved their goal.
In a blink of an eye, we have entered a beautiful June, which is a great opportunity to plant trees and green the country. In order to create a good green home and protect the ecological environment, I suggest that students:
Love nature, love flowers and trees, and protect animals.
Carry out tree planting and green protection activities.
Actively publicize environmental protection and let environmental awareness enter thousands of households.
