Презентация на тему по экологии на тему Экология Якутии

one of the rare places on Earth where the

purity of nature and a correspondingly amazing variety of flora and fauna are left untouched.

problems and today the key problem is preservation of

these enormous natural riches.

Yakutia is well endowed with raw materials. The soil contains large reserves of oil, gas, coal, diamonds, gold, silver, tin, tungsten and many others.
Republic of Sakha (Yakutia) produces 99% of all Russian diamonds and over 25% of the diamonds mined in the world

of the longest rivers in the world. It rises

west of Lake Baikal in southern Russia and eventually flows north for 4,400km before emptying into the Laptev Sea.

Ecological problems:
Overfishing
Mining
Forestry
Grazing
Expanding agricultural activities
Water diversion for irrigation
Pollution from fertilizers and pesticides

forests.
Timber or wood is another important resource found in

Republic of Sakha (Yakutia).
Often, timber is cut down to make room for a mineral mine.
Deforestation reduces water quality, causes erosion, & kills animals’ habitats.

central Yakutia, which annually brings a lot of trouble.

Fire burns up valuable forests, burn the soil, the plants are destroyed, killed a lot of wild animals, birds and insects.
Toxic products of combustion are washed away by rains into rivers and lakes and pollute the environment.

natural resources
There are valuable resources beneath the soil. It

is very important to economy of Republic of Sakha (Yakutia).

Minerals:
Gold
Silver
Copper
Zinc
iron ore, uranium, nickel and others

machinery are reasons that the land around mines is

damaged and the environment is often ruined
Slag or leftover rock from the smelting process, is often dumped in any convenient place
Mining processes release harmful chemicals into the air, which causes acid rain.

Sakha (Yakutia)
Burning of fossil fuels:
Fossil fuel is geologic deposits

of organic materials, formed from decayed plants and animals that have been converted to crude oil, coal, natural gas, or heavy oils by exposure to heat and pressure in the earth's crust over hundreds of millions of years.
The burning of fossil fuels by humans is the largest source of emissions of carbon dioxide, which is one of the greenhouse gases that allows radiative forcing and contributes to global warming.

Sakha (Yakutia)
Mining operations:
Mining is a process where in minerals

below the earth are extracted using large equipment.
During the process dust and chemicals are released in the air causing massive air pollution.

of transportation
Conserve energy
Understand the concept of Reduce, Reuse and

Recycle
Emphasis on clean energy resources
Use energy efficient devices

(Yakutia)
Central Yakutia has high population density
Yakutsk has a lot

of enterprises located in the windless places(60 smog days in a year), transport produces 80% of emissions.

(Yakutia)
Western Yakutia - (Mirny, Ayhan, Udachnyi, Lensk)
There are

the diamond industry, oil and gas companies.
Also river Viluy is polluted by phenols, hydrogen sulfide. There has been a dramatic reduction in fish stocks, trout, whitefish, sturgeon have disappeared.
Ecosystem got radiation (accidental explosions "Kraton-3" and "Crystal“) as a result of underground nuclear explosions.

(Yakutia)
In South Yakutia there are large mining and enrichment

companies.
Coal mining in Neryungri, GRES are the major contributors to the pollution emissions.
Priority pollutants - nitrogen oxide and dioxide, benzopyrene, sulfur dioxide.
Unique lake Big Toko is under threat from pollution and destruction in connection with the development of Elga coals.

conservation and protection of nature, all of its components,

forests; • reforestation, planting; • waste management; • limit on hunting, fishing; • monitoring; • Creation of environmental safety information; • Сreation of a system of environmental education; • Сhanges in people's consciousness.

also the duty of every person, citizen is to

preserve and protect nature.
