00:00:03,890 --> 00:00:13,970
hello happy friends already know that jobs are divided into three sectors primary a production

2
00:00:13,970 --> 00:00:23,929
sector secondary or manufacturing sector and tertiary or service sector today we're going

3
00:00:23,929 --> 00:00:38,320
to work in a secondary sector the secondary sector has jobs which transform raw materials

4
00:00:38,320 --> 00:00:45,060
into elaborated products and the main activities which compose this sector are

5
00:00:45,060 --> 00:00:56,670
factories or industries, crafts and constructions. We're going to get to know

6
00:00:56,670 --> 00:01:08,159
a little more about each one of these activities. Factories or industries are

7
00:01:08,159 --> 00:01:13,579
able to produce elaborated products with machinery. They are usually large

8
00:01:13,579 --> 00:01:20,079
buildings where lots of people work a large quantity of products are produced

9
00:01:20,079 --> 00:01:36,069
the industry can be classified into base industries usage industries and

10
00:01:36,069 --> 00:01:49,760
equipment industries base industries transform raw materials into semi

11
00:01:49,760 --> 00:01:55,099
elaborated products they produce products which act as raw materials for

12
00:01:55,099 --> 00:02:05,730
other industries for example they produce a wooden boards from trees usage

13
00:02:05,730 --> 00:02:10,969
industries transform semi elaborated products into products which are

14
00:02:10,969 --> 00:02:18,449
directly sold to people for example the chairs which are made with wooden boards

15
00:02:18,449 --> 00:02:29,020
from trees equipment industries produce machinery or technology used for other

16
00:02:29,020 --> 00:02:40,080
industries for example they make saws hammers and nails to be able to build

17
00:02:40,080 --> 00:02:46,060
chairs industries can also be classified according to the raw materials they use

18
00:02:46,060 --> 00:02:52,960
and the products they make there are chemical industries which produce for

19
00:02:52,960 --> 00:03:02,919
example plastic food industries who produce nutritional products or automobile industries

20
00:03:02,919 --> 00:03:20,349
producing cars crafts are made by craftsmen they create their works in small workshops

21
00:03:20,349 --> 00:03:28,210
and they develop the products with their own hands a very simple machines like this sculpture

22
00:03:28,210 --> 00:03:32,430
Or these craftsmen making handbags

23
00:03:32,430 --> 00:03:43,560
Construction is in charge of completing whole buildings and engineering works

24
00:03:43,560 --> 00:03:47,400
Such as bridges, tunnels or roads

25
00:03:47,400 --> 00:03:53,699
The truth is that the amount of buildings and roads constructed is incredible

26
00:03:53,699 --> 00:03:55,379
Don't you think?

27
00:03:56,400 --> 00:04:03,509
Now we've got to know the secondary sector

28
00:04:03,509 --> 00:04:09,009
But there's something very important which you need to know and we cannot forget.

29
00:04:10,050 --> 00:04:22,079
There are lots of factories which are gravely contaminating our air, floor and water.

30
00:04:26,209 --> 00:04:32,209
They look for their own economic profit without thinking of the damage they produce to all surroundings.

31
00:04:36,089 --> 00:04:42,110
That's why we're asking everyone who works in the secondary sector to take care of our planet.

32
00:04:42,110 --> 00:04:51,110
Don't dump residue into nature and use clean and renewable energies.

33
00:04:51,110 --> 00:04:57,290
This is the only way we can achieve a better world.
