Ex.2. Read the article using dictionary
The main threats to biodiversity in Uzbekistan are major habitat loss or alteration.
Uzbekistan’s economy and security is heavily dependant on water resources, both in terms of quality and availability, and natural ecosystems play important role in numerous ways in protecting both quality and availability of water supplies. Healthy ecosystems provide numerous local and national benefits ranging from erosion control, prevention or reduction of natural disasters (such as floods and landslides), to climatic amelioration and the potential for sustainable economic utilization.
The most significant loss of ecosystem services in Uzbekistan, and the greatest man-made disaster, is the loss of the Aral Sea and the Amudarya delta. The ecological impacts of the Aral Sea disaster have greatly increased the vulnerability of local populations to health problems.
Direct impacts of damaged ecosystems on people include increased ill-health due to wind blown salt and dust, excessive use of agro-chemicals, salinity of the soil, heavy salt concentration in potable water, contamination and chemical pollution. All these factors cause immune system deficiencies and mutations including cancers, kidney diseases, respiratory diseases. Such problems are more frequently registered in areas with damaged ecosystems.
