We must have an environmental crisis
Teachers, classmates Good morning everyone. Very pleased to stand here and discuss something ---- Although I am nervous. The air here today, so fresh, the scenery outside the window is also good, the scene is very intense atmosphere. But had to admit that today's sky no longer blue we were young then, and the air is not as fresh. But also very lucky, because today we can at least do not wear a mask to be here. But who knows after years of not wearing a mask in this group of people to listen to speech? So, today I talk about the topic of the environment as we have to have a sense of crisis.
In recent years in promoting low-carbon life, the so-called "low-carbon life", often refers to a to minimize resource consumption and environmental pollution, life. This idea of course is very good, but no doubt it will certainly be the future way of life. Otherwise, the environmental situation facing humanity will quickly devour human beings. Do not forget, the most brutal natural place, precisely because it was the most meaningful way to create life on, he lives the most meaningless way to die.This is not alarmist talk (this is not an exaggeration)
If we only consumed a lot of material and energy, not to care about the environment situation, we have thought about what the future world is it? Refuse to do future world is it? We will dare to wear a mask breathing? The future can only be seen in the documentary, animals and plants before it? We have always said that the earth is limited, these things really right. But in fact, we only realized that the "resource limit", "energy limit," not aware "of pollution limits." First, a high consumption of modern life to material and energy. Developed countries, those who live a modern life, each day the daily lives need to consume a large amount of resources. Even the least developed countries (developing countries) of the material energy is not small. The city is now mostly by the huge energy consumption to maintain: we are now on the energy used in lighting is very alarming, to the millions of air-conditioned summer, winter, and also warm. It can be said, more modern life, material and energy consumption of the more severe. More seriously, a high degree of pollution of the environment of modern life. Agricultural civilization in the past, the vast majority of waste generated in life are biodegradable, but now lives of our city by the massive amount of spam, many of which are non-degradable. Every big city has some great around the landfill. This state is like a house than you live, but you can not throw the garbage generated every day to go outside the house. So, you have to put in the room next to a trash can, rubbish installed inside. Do you think as long as the garbage can cover up the box, and anyway, the rest of the house is clean. But, you know, if you never throw out the garbage, then, must one day you will take the garbage produced by your house most of the space. So there is an extremely pessimistic view: "The future world is a waste to do." In fact, the city just made it to the pollution around it, but they still persist on this planet, but living in big cities we usually do not see it.
Despite the large size of the Earth, but is still limited. Limited on the one hand say that the Earth can provide materials and energy are limited; the other hand, also means the ability of the earth to withstand pollution is limited. Because of this pollution limit problem, do not often appear in the vision of our daily lives, so there are many cases which we ignored. In fact, than the "resource limit", "pollution limits," will likely occur earlier. Because of the shortage of resources can do to further the development of science and technology to solve. For example, solar energy, in fact, we are able to use solar energy on Earth, but the sun's energy can provide an extremely small part of it. So, in fact, still very energy can be used as space and potential, now more critical and more difficult problem is pollution. In fact, many of the pollution treatment, only pollution transfer only.
Well, now for each of us can do it? I think we can do one thing first, is bound to their material desires. Indeed, the pursuit of material life of people is not enough, good can be better. But I think, for those who in life had been satisfied to some extent, we give him about contentment, not speaking to the unrestricted pursuit of material enjoyment, is feasible. Environmental problems facing China is very serious. Dust, water pollution, pollution, white trash, vegetation coverage is low ...
