Problems of UB

Ulaanbaatar is the capital of Mongolia. It was established in 1639 and aggresed with 9 districts. Although our city is developing very rapidly , it is causing lots of problems. Nonetheless during the development, there have been some problems which are very important to be decided shortly.
There are 3 main problems must be decided.
First main problem is water pollution.The simple pleasures may soon become may soon become a thing of the past. Factors are polluting our rivers, lakes
such as Tuul Orkhon, Kherlen, Baigal with dangerous chemical elements.
Tons and tons of industral and domestic waste are poured into them. Consquently nature is being changed and people are destroying their future with their hands.
You need to remember that human can't live without clear water. Secondly, air pollution's necessary resue. The cars , factories and ger districts in the UB are giving off dangerous fumes to clear blue say.
In the past few years,It is influencing people health so, Heart disease and problems of lungs are rapidly increasing.
If we don't do something now, our cities will become dangerous to live in there.
Next problem is rainforest.
Everytime we breathe by Oxygen and, breath out the hydrogen why there are so many breathing problem? because people are cutting rainforests for produce energy for heat ,paper,and any types of wooden things.
people are dying of hunger, air is being polluted , crops are falling see and rivers and lakes are being contaminated more.
Finally only when all the rivers have been run dry.
Only when all the blue sky have been fulled with smoke only when all the rainforest haves been burnt down, it's too late to save the earth.
So we need to be look for ways to overcome those problems we can put pleasure on those in power.
We can do it all together.
So the goverment must make laws ,give directions to overcome it and support the people who are exploring the new technology and way to discuss that problems.
