<span>The answer is two. It
was started in the 1970s where the Chinese government enacted. This was due to the continuation of the
Cultural Revolution and the pressure it put the nation through. Though there
have been reports in 2015 that the government may have made changes in these
laws due to the aging problem in China. The new laws were approved in session on
December 27, 2015 and became effective on January 1, 2016.</span>
Everything changed during the Industrial Revolution, which began around 1750. People found an extra source of energy with an incredible capacity for work. That source was fossil fuels — coal, oil, and natural gas, though coal led the way — formed underground from the remains of plants and animals from much earlier geologic times. When these fuels were burned, they released energy, originally from the Sun, that had been stored for hundreds of millions of years.
Coal was formed when huge trees from the Carboniferous period (345– 280 million years ago) fell and were covered with water, so that oxygen and bacteria could not decay them. Instead, the pressure of the weight of materials above them compressed them into dark, carbonic, ignitable rock.
Most of the Earth’s oil and gas formed over a hundred million years ago from tiny animal skeletons and plant matter that fell to the bottom of seas or were buried in sediment. This organic matter was compacted by the weight of water and soil. Coal, oil, and gas, despite their relative abundance, are not evenly distributed on Earth; some places have much more than others, due to geographic factors and the diverse ecosystems that existed long ago.
Early Steam Engines
The story of the Industrial Revolution begins on the small island of Great Britain. By the early 18th century, people there had used up most of their trees for building houses and ships and for cooking and heating. In their search for something else to burn, they turned to the hunks of black stone (coal) that they found near the surface of the earth. Soon they were digging deeper to mine it. Their coal mines filled with water that needed to be removed; horses pulling up bucketfuls proved slow going.

To the rescue came James Watt (1736–1819), a Scottish instrument-maker who in 1776 designed an engine in which burning coal produced steam, which drove a piston assisted by a partial vacuum. (There had been earlier steam engines in Britain, and also in China and in Turkey, where one was used to turn the spit that roasts a lamb over a fire.) Its first application was to more quickly and efficiently pump water out of coal mines, to better allow for extraction of the natural resource, but Watt’s engine worked well enough to be put to other uses; he became a wealthy man. After his patent ran out in 1800, others improved upon his engine. By 1900 engines burned 10 times more efficiently than they had a hundred years before.
At the outset of the 19th century, British colonies in North America were producing lots of cotton, using machines to spin the cotton thread on spindles and to weave it into cloth on looms. When they attached a steam engine to these machines, they could easily outproduce India, up until then the world’s leading producer of cotton cloth. One steam engine could power many spindles and looms. This meant that people had to leave their homes and work together in factories.
Early in the 19th century the British also invented steam locomotives and steamships, which revolutionized travel. In 1851 they held the first world’s fair, at which they exhibited telegraphs, sewing machines, revolvers, reaping machines, and steam hammers to demonstrate they that were the world’s leading manufacturer of machinery. By this time the characteristics of industrial society — smoke rising from factories, bigger cities and denser populations, railroads — could be seen in many places in Britain. Hope this helps!

Many Droughts ( Because deserts Dont have Water) Shortagw of Food they cannot plant Crops, because the Crops cant live in the desert. Also Animals Cant Live there Either
Any Questions PM me ;)
Answer:
b. the total consumer surplus will be the area beneath the demand curve but above the current price of backpacks
Explanation:
A situation where there are many buyers in the backpack market indicates that the demand for this product is high, so the consumer surplus that will be received by the backpack manufacturer will depend on how much the consumer is willing to pay for the backpack, in which case Total consumer surplus will be the area below the demand curve, but above the current price of the backpacks.
ok
