Faced with the increase in the cost of treating sewage discharge, the Japanese government is unable to deal with nuclear wastewater, and intends to dilute it and discharge it into the sea, which has been criticized by the people of the world.
The word nuclear, it smells discolored
Pollution emissions have always been a problem for human beings.
As an early industrial country, the United States has always maintained high industrial emissions, and it has only improved since the end of the last century. It took three decades to reduce industrial emissions to achieve an excellent target task.
This goal was achieved by China in 7 years, which made the United States Bloomberg praise it without hesitation. Countries around the world are working to reduce pollution and emissions, but there is still one country that is worrying, and that is India.
Historical origins
The excessive pollution and destruction of the environment by human beings began with the Industrial Revolution, especially since the second industrial revolution, the emergence of electricity has become an important energy tool, and people rely on the power system for large-scale industrial operations.
Due to historical limitations, a large number of industrial wastewater and waste gas are indiscriminately discharged and indiscriminately discharged, blindly pursuing development, resulting in a sharp deterioration of the environment.
The tip of the iceberg of human environmental damage
In 1962, American biologist Rachel Carson published a book called "Silent Spring", which described the pollution of the environment by pesticides and the disaster caused by the endless environmental destruction of human beings.
This has made people who are determined to develop gradually realize the importance of protecting the environment.
Since then, the United Nations has convened a conference on the human environment, trying to reduce people's pollution of the environment and achieve long-term stable development of mankind through the conference, and the signing of the famous "Declaration on the Human Environment" after the conference has officially become the beginning of the attention of governments to protect the environment.
Under the World Conference on the Environment, peoples have come together to specify strategies
Governments have begun to plan emission reduction targets and commit themselves to the implementation of pollution reduction and emission reduction.
It took the United States 30 years since 1970 to reduce the proportion of particulate emissions by 44 percent. And China fell by 40 percent in just seven years.
A green ecological environment is our pursuit
The former was originally a rather remarkable emission reduction achievement, but in the face of China, it was eclipsed.
Bloomberg wrote in the headline that China has reduced air pollution in 7 years as much as the United States has reduced in 30 years, helping to reduce the global average smog level.
Pollution hazards
The harm of environmental pollution is multifaceted, it is a disaster for the natural world, the environment on which it depends is broken, the animals are displaced, and the destruction of some species under harsh conditions, and ultimately endanger human beings themselves.
In history, there have been many harms caused by environmental pollution to human beings.
The first American Donora Incident, which took place in a small town in the United States named Donora.
The mist is not a fairyland but a region
At that time, due to the impact of the secondary industrial revolution in the United States, various chemical industries were thriving and flourishing, and industrial gases in various regions were unscrupulously emitted, under the influence of climatic conditions.
There are many harmful gases from nearby areas accumulated in the air of Donora, and people have symptoms such as dizziness, nausea and diarrhea after inhaling these harmful gases.
According to data at the time, more than 40 percent of Donora's people suddenly fell ill, resulting in 17 deaths.
The analysis believes that the harmful gases at that time came from the fact that the products of SO2 and its oxidation were combined with dust particles in the atmosphere, resulting in adverse reactions after people inhaled.
Second, in 1952, the hospital in London, England, was exceptionally busy, with four days of winter.
Bustling London brings a lot of industrial pollution
London has been shrouded in smog for a long time, and the number of deaths has increased by more than 4,000 compared with the usual year.
The number of deaths due to bronchitis, coronary heart disease, tuberculosis, and heart failure is 2 to 9 times that of the usual number of deaths from similar diseases.
Due to the large amount of coal consumption in London at that time, the concentration of dust particles in the air was greatly increased, and fe2O3 in the smoke promoted the oxidation of SO2 to SO3, thereby forming H2SO4, and acid mist was formed on this basis.
Cities obscured by smog deserve to be reflected
This acid mist can pose a certain threat to precision instruments, and it has a huge lethality to the human body.
There are many cases of human pollution in history, and these cases are sounding one alarm bell after another for us to endanger the environment, which is to endanger human beings themselves.
China's efforts
China's efforts to reduce emissions are visible to the naked eye. In the winter of 2011, the streets of Beijing were thick with fog and dust.
The thick sand dust stained the environment yellow
Even at noon, the air is still mixed with thick yellow sand, and the pedestrian roads are in a hurry, and even if there is no epidemic, you need to wear a thick mask.
After investigating the causes of smog, the government has taken a series of rectification measures to treat the symptoms, and this series of political measures has also become the object of emulation in all provinces across the country.
First of all, in terms of remediation and discharge, we will start from a variety of industrial sources and carry out multi-pronged treatment.
The sky is clear, the wind is gentle and smooth
Implement regional joint prevention and control, and pay close attention to the discharge and pollution reduction in the areas around Beijing to form a regional effect.
In this regard, the government has also issued special rules and regulations to strictly limit industrial emissions, and establish a tripartite monitoring platform to effectively monitor pollution discharge, and timely stop non-standard polluting enterprises.
Adjust the industrial structure from the key sources, especially strengthen the development of the tertiary industry, and increase the proportion of the tertiary industry in the city.
Call on the public to participate in environmental governance, carry out public welfare film publicity, and promote the concept of environmental protection to penetrate the hearts of the people.
After a series of measures to reduce pollution and emissions, Beijing has returned to the previous clear skies, and the whole country has taken this as a benchmark, and in the past seven years, it has successfully completed three decades of emission reductions in the United States. Let's turn our attention back to the worrying India.
The problems facing India
According to the World Air Quality Data Report, India has the third highest average PM2.5 in the world.
A mask like a gas mask
As a populous country, India needs to consume a large amount of energy supplies every year to supply the people.
And in terms of energy, they are also making extensive use of traditional coal and other energy resources that are hugely polluting the environment, resulting in low air quality.
In the data pointed out by Bloomberg, nearly half of the global pollution increase comes from India, even if the Indian side has taken measures, but the actual action can not be implemented, coupled with India's own needs to develop, it is impossible to truly solve the source of the industry.
They were happy because there was energy available
In India, which promised to improve pollution in 2020, the pm2.5 indicator in the air actually rose by 2.9%.
In addition, according to Indian data, India's sulfur dioxide emissions for five consecutive years are more than twice the world's highest than Russia, which ranks second. This data is not an exaggeration.
At that time, professors at the University of Chicago took their teams to the capitals of China and India to test. According to the survey, New Delhi's data is much better than Beijing's, but New Delhi's outdoor visibility is not high, and the smog severity exceeds that of Beijing.
Unscrupulous incineration emissions are subtly affecting the environment
Why is the pm2.5 indicator lower than beijing? Later, when he returned to the United States, the professor found that when the pm2.5 indicator instrument exploded in India, a new value appeared, and if it was to be calculated, it had to be counted in the part of the explosion.
In other words, the pm2.5 indicator in the Indian capital is a burst value, plus existing data tests. In this way, India's pollution levels are already precarious.
More than half of India's electricity sources come from coal, one of the most polluted sources of energy, but due to technical conditions, they cannot use new energy sources like China.
Every day, a large number of people and industrial equipment are waiting for electricity, and they only choose to sacrifice the environment to meet temporary energy needs, which is tantamount to drinking and quenching thirst.
Indian characteristic garbage mountain
Compared with India, the mainland's energy resources have gradually expanded from the initial high-polluting power generation such as coal to hydropower, wind power, photovoltaic power generation and other methods.
Meet the daily needs of the people together. Nowadays, under the guidance of policies, traditional fuel-consuming vehicles are being replaced by new energy vehicles, and the emissions of the mainland will be further reduced!
At the UN Climate Treaty Conference, Indian Prime Minister Narendra Modi set a national emissions reduction target: India will achieve net zero emissions by 2070, and the near-term target is 2030.
That is to say, India will still have a large number of emissions in the near future, and the pm2.5 indicator may not decline, but will rise.
In this way, the net zero emissions target achieved by 2070 may also be just a pie
