(perantara) Spesies terancam.

00:00:04,654 --> 00:00:06,794
Mungkin anda mendengar istilah
itu sebelumnya,

4
00:00:06,794 --> 00:00:09,563
tapi apakah sebenarnya spesis
terancam?

5
00:00:09,563 --> 00:00:11,493
Dan kenapa mereka perlukan
bantuan kita?

6
00:00:12,030 --> 00:00:13,563
Mari kita siasat.

7
00:00:13,563 --> 00:00:16,663
Perkataan 'spesis' merujuk
pada satu kumpulan

8
00:00:16,663 --> 00:00:20,423
atau sejenis hidupan yang sama
yang boleh berkembang.

9
00:00:20,843 --> 00:00:24,273
Contohnya, manusia adalah
spesis,

10
00:00:24,273 --> 00:00:28,803
tapi haiwan, tumbuhan dan serangga
yang berlainan juga adalah spesis.

11
00:00:29,243 --> 00:00:31,313
Singa, burung hantu, cicak,

12
00:00:31,313 --> 00:00:33,623
rama-rama, semut dan lebah,

13
00:00:33,623 --> 00:00:36,263
pokok, rumput dan bunga yang
kita tanam,

14
00:00:36,263 --> 00:00:41,230
bahkan contoh spesis yang lain. buah-buahan dan 
sayuran yang kita makan.

15
00:00:41,230 --> 00:00:44,243
Tapi apakah maksudnya, apabila spesis
terancam?

16
00:00:44,243 --> 00:00:46,843
Secara zahir, spesis terancam
bermaksud:

17
00:00:46,843 --> 00:00:50,103
spesis yang dalam 
kepupusan

18
00:00:50,103 --> 00:00:53,703
atau lenyap 
sepenuhnya.

19
00:00:54,363 --> 00:00:57,203
Bagi membantu jejaki
spesis tersebut

20
00:00:57,203 --> 00:00:58,953
dan betapa terancamnya ia,

21
00:00:58,953 --> 00:01:01,843
ia diletakkan dalam kategori,
berdasarkan perkara seperti:

22
00:01:01,843 --> 00:01:06,083
populasinya, habitat, dan data 
saintifik yang lain.

23
00:01:06,501 --> 00:01:10,621
Kumpulan-kumpulan dari lingkungan 
yang sedikit hingga pupus sepenuhnya.

24
00:01:10,621 --> 00:01:15,002
Sementara semua kumpulan ini sedang
dinilai,

00:01:15,002 --> 00:01:17,884
spesis tersebut disenaraikan

spesis tersebut diancam
kepupusan.

28
00:01:23,032 --> 00:01:27,584
Apakah penyebab spesis
menjadi terancam dan pupus?

29
00:01:28,324 --> 00:01:29,954
Mari lihat satu contoh.
