), is a country located in the southern portion of the Indochina Peninsula in Southeast Asia.
The most severe activity in this regard is considered to be the countrywide deforestation, which also involves national parks and wildlife sanctuaries.
Overall, environmental destruction in Cambodia comprise many different activities, including illegal logging, poaching of endangered and endemic species, and destruction of important wildlife habitats from large scale construction projects and agricultural businesses.
Different kinds of glass beads recovered from several sites across Cambodia, such as the Phum Snay site in northwest and the Prohear site in southeast, show that there were two main trading networks at the time.
The two networks were separated by time and space, which indicate that there was a shift from one network to the other at about 2nd–4th century AD, probably with changes in socio-political powers.
The most curious prehistoric evidence in Cambodia are the various "circular earthworks" discovered in the red soils near Memot and in the adjacent region of Vietnam in the latter 1950s.
Their function and age are still debated, but some of them possibly date from 2nd millennium BC.Iron was worked by about 500 BC, with supporting evidence coming from the Khorat Plateau, in modern-day Thailand.In Cambodia, some Iron Age settlements were found beneath Baksei Chamkrong and other Angkorian temples while circular earthworks were found beneath Lovea a few kilometres north-west of Angkor.The Khmer endonym Kampuchea derives from the Sanskrit name Kambojadeśa (कम्बोजदेश), composed of देश, desa ("land of" or "country of") and कम्बोज, Kambojas, which alludes to the foundation myths of the first ancient Khmer kingdom.There exists sparse evidence for a Pleistocene human occupation of present-day Cambodia, which includes quartz and quartzite pebble tools found in terraces along the Mekong River, in Stung Treng and Kratié provinces, and in Kampot Province, although their dating is unreliable.Archaeological records for the period between Holocene and Iron Age remain equally limited.
