Environmental protection is supposed to "guarantee"?

Environmental protection is supposed to "guarantee "?

Beijing News weekly, the new knowledge

In Copenhagen on forces around "emissions" of some of lock, they were always to think about what exactly you want to rely on environmental protection — — get United Kingdom, it may help expand some thought.

Before the middle ages, the United Kingdom has been behind the development of the European continent and thus retains a lot of the forest.

London South of the name Weald, mountainous County is not suitable for farming, retains a large high-quality Woods, become iron Center. United Kingdom troops take advantage of the rich forest resources here, to create a large number of guns and ammunition, finally challenge to the European continent.

However, the United Kingdom, seeing the forest is unsustainable.

1547 years, Duke of Somerset (The Duke ofSomerset) established a Committee to investigate the Weald forest decline, but was arsenal and some politicians resist. Local forbearance, began destroying blacksmith furnace. The opposition just like to take this opportunity to "treason" in the name of the Duke of Somerset, strangling arrested. Politicians trick cover up the fact that the forest is less and less, British life overhanging a line. But the United Kingdom did not finish, save the forests, the United Kingdom is today seen people hate, known as the "world's dirty energy," coal.

United Kingdom and China, coal, but quality is not good, burning stifling.

Even if everyone is aware of the forest cut out faster, rather than burning coal. This shows that environmental education alone is useless.

Finally economic levers.

Forest decline, timber prices higher and higher. At that time, the cost of iron-making industry in the United Kingdom, the charcoal already account for over 80%. Urban heating first into a burning coal, "fog are" the nickname so. Queen hated soot, coal has been banned. Can people prefer breathing dirty air rather than spend a lot of money to buy charcoal, command has quickly become a dead letter. In this way, the United Kingdom will remain a little forest. In fact, coal has also been saved whales. Before Europeans more whale oil for lighting, then Canada's AbrahamGesner invented the manufacturing technology of kerosene, whaling before they disappear. This description, evaluation of a new technology for environmental protection, to large scale to measure.

However, for many industries, coal is harmful.

For example, in brewing drying malt required using coal to stem this would affect the taste of wine, or do you want to use charcoal. 1603, HenryPlatt thought, you can refine the charcoal as the coal into Coke. This process can be dropped in the desulfurization, smoke less. So the brewery from the charcoal in the liberated, reducing the demand for wood, protection of the forest. This shows that, in order to environmental protection, the new technology is the kingly way.

Iron also don't like coal, because sulfur once mixed with into the iron that will let the iron brittle.

Interestingly, the blacksmith and wine master seems to have never contacts, coke manufacturing process until 100 years later, in 1709 was a man called AbrahamDarby brought into the ironworks. He created the world's first "Coke for blast furnace iron-making industry", and finally to charcoal. This means that if you want to join the environmental protection, technology transfer is the kingly.

The "Coke for blast furnace" is one of the three pillars of the industrial revolution, the other two pillars also and coal has a close relationship.

First of all, the more coal miners dig deeper, groundwater seep out. This will let mine waste away. At that time, the United Kingdom's "coal boss" can only hire people who have bailed out, the efficiency is very low. 1712 years ThomasNewcomen invented the steam-driven water pump, solved the problem. This game was later transformed into steam, which is the industrial revolution of the second pillar.

Transport coal there is a problem.

HuntingtonBeaumont tracks for this invention. The next thing is a matter of course, the train was born. This is the industrial civilization of the third pillar, this pillar saves costs and dramatically improves the range of human activities.

The desire for energy, used to be the greatest of human progress.

But the industrial revolution brought vast amounts of carbon dioxide released. This story tells us that the problems brought about by technological development or do you want to go back through technology development.
