Environment in Trakya
The most important natural resource in Trakya Region is the arable land which yields at least one crop every year and covers almost the entire Region. In addition to this, rich groundwaters; the Longoz forests within the boundaries of Kırklareli province and other natural assets; the Black Sea, the Marmara Sea and the Aegean coasts; the Ergene River, which arises in the Yıldız Mountains, flows into the Region and into the Aegean Sea after joining the Maritsa River; and other mineral resources including primarily lignite and coal mines are other significant natural resources of the Region
Environmental pollution is one of the important issues which Thracians deliberate over. Cheap groundwater utilization in large amounts by the industrial production sites particularly in Çorlu-Çerkezköy-Lüleburgaz line has exorbitantly increased pollution in the Region. As the rate of municipalities equipped with water treatment plants is only 5% of the total, as well as the existence of many industrial plants without a treatment plant is enough to explain how such pollution occurred. The Marmara Sea, on the other hand, has been seriously polluted due to the urbanization around it, especially after the 1980's and the liquid waste arising from this. Moreover, the level of pollution in the Ergene River has reached an irrevocable point and the river has become unfavorable for life. The Istranca Mountains and their vicinity draw attention in terms of soil and water pollution as the cleanest region. This region hosts an unspoiled natural structure and the Longoz forests, which were built up over years.
Edirne and Tekirdağ provinces in Trakya are the provinces with the highest air pollution in Turkey. However, air pollution outside city centers has not been a major issue in the Region.
Lignite, which is abundant in the Region's natural resources, is not suitable for use as it is low-calorie and a source of environmental pollution.
