Topic 2. The saiga antelope, or saiga, is a critically endangered antelope which during antiquity inhabited a vast area of the Eurasian steppe spanning the foothills of the Carpathian Mountains in the northwest and Caucasus in the southwest into Mongolia in the northeast and Dzungaria in the southeast.
Once numbering in the millions, the saiga population crashed by 95% in fifteen years, the fastest decline ever recorded for a mammal species. They are now critically endangered. In May and early June of 2015, over 200,000 saiga in central Kazakhstan died suddenly due to a respiratory illness.
Saiga is a relatively small cloven-hoofed animal, body length 110-146 cm, tail 8-12 cm, height at the withers 60-79 cm. Weight 23-40 kg. Saiga lives in Kazakhstan, Uzbekistan, Kyrgyzstan, Turkmenistan, Russia and western Mongolia. In 2002, the International Union for Conservation of Nature, this species was classified as "CR", that is, "in critical condition." Saiga are on the verge of extinction, because poachers hunt for their skins and meat. We need to build more nature

We need to build more nature
1.The root grows thicker with age and helps support the tree.
2.In trees as large as the coast redwood of California, the water may travel 400 feet from the lowest roots to the highest leaves.
3.This seems against the laws of nature as the most efficient suction pump can raise water to only 33 feet.
4.Bryophytes are very small, even the "giants" of this group rarely grow taller than 15 centimetres.
5.The ferns are better adapted to land than bryophytes.
6.We probably depend much more on the flowering plants than on any other type of plants.
7.In vascular plants the sporophyte is more conspicuous than in bryophytes.
8.A genus is a larger group than a species.
9.Species of one genus are closer related to each other than to other kinds of plants.
10.All plants in the world may be divided into phyla, which are farther divided into smaller groups called classes.
