I used to worry about the darkness at night, but now the night becomes brightly lit; I always wanted to taste the delicious food in the sea before, but now fish and shrimp in rivers and seas have become commonplace; In the past, I always found it difficult to deliver letters from home, but now, heaven is still our neighbor ... Yes, a series of problems brought by science can not be ignored!
Scientific inventions have brought us short-term pleasure, but also long-term problems. With the development of world industrial economy, the rapid increase of population, the unlimited rise of human desire and the uncontrolled production and lifestyle, the world climate is facing more and more serious problems, carbon dioxide emissions are increasing, the ozone layer of the earth is suffering from an unprecedented crisis, and global catastrophic climate changes appear frequently, which has seriously endangered the living environment and health and safety of human beings. Even the rapid growth or expansion of GDP, which mankind once prided itself on, has been greatly reduced by environmental pollution and climate change. Low-carbon life is a healthy lifestyle advocated by global environmentalists, aiming at protecting the earth and the living environment.
The earth is our mother, and it provides all kinds of resources for human beings to live on without reservation, but we don't know how to cherish these resources. We also destroy natural resources at will, such as deforestation and waste gas emission, which leads to soil erosion, trees being replaced by yellow sand, destructive storms increasing and biological species decreasing. Aren't these man-made
For the sake of our homeland not being buried by yellow sand, don't let the last drop of water become our tears, and for a better tomorrow, let's work together to protect the environment now.
Turning off the lights and unplugging is only the first step, which is also the embodiment of personal cultivation; When we need to print documents or materials, each piece of paper is printed on both sides, which is equivalent to saving half of the forest that was originally to be cut down; If our family lives on a higher floor, climbing stairs instead of taking the elevator can not only save everyone's electricity bill, but also exercise; There is no need to turn on all the power lights when you walk into the house. The electric light was invented only 130 years ago, and it had been well used hundreds of years before that. Daily rice washing water can be used for washing hands, cleaning furniture and watering flowers. Clean, hygienic and naturally moist; Not only mahogany and leather can reflect the taste of home, bamboo furniture is recommended because bamboo grows faster than trees; When we have a car at home, we can drive as few private cars as possible. When we are going to a place not far away, we will ride bicycles instead. We can also use waste to "turn waste into treasure", which is an indispensable element.
What we are facing is the deteriorating environment, exhausted fossil energy and high cost of living ... In fact, as long as we raise our hands, we can make the world a better place. Protecting the environment and saving energy are our basic national policies. To achieve sustainable development, we should not only promote the harmony between man and nature, but also coordinate economic development with population, resources and environment. We should also adhere to the civilized development path of production development, affluent life and good ecology to ensure sustainable development from generation to generation.
Someone once said, "We should protect our homeland, and only we can change our future life.". As we prepare for the world war, we must unite to prevent the temperature from rising. Climate change is happening and it threatens the rights and safety of everyone on the planet. " As long as everyone saves a drop of water, you can save hundreds of millions of drops of water. Although everyone has this meager strength, how powerful it is to unite!
Students, science has brought us too much, brought us convenience, but also brought us a lot of potential and long-term harm. Therefore, if we want social development and progress of the times, we must give priority to science. If you want to live a better life and pass it on from generation to generation, you naturally have to take the lead. The Book of Changes says, "Kang Long has regrets", so while developing science, we should not abuse scientific achievements, take nature as the guide, adjust the relationship between science and life, let science bring us more beauty and less harm, and make our life look brand-new and beautiful!
