PollutionPollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of any substance (solid, liquid, or gas) or energy (such as radioactivity, heat, sound, or light). Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Although environmental pollution can be caused by natural events, the word pollution generally implies that the contaminants have an anthropogenic source – that is, a source created by human activities, such as manufacturing, extractive industries, poor waste management, transportation or agriculture.

AtticaAttica (Αττική, Ancient Greek Attikḗ or , atːikɛ̌ː or atiˈci), or the Attic Peninsula, is a historical region that encompasses the Athens metropolitan area, which consists of the city of Athens, the capital of Greece and the core city of the metroplitan area, as well as its surrounding suburban cities and towns. It is a peninsula projecting into the Aegean Sea, bordering on Boeotia to the north and Megaris to the west. The southern tip of the peninsula, known as Laurion, was an important mining region.
SmogSmog, or smoke fog, is a type of intense air pollution. The word "smog" was coined in the early 20th century, and is a portmanteau of the words smoke and fog to refer to smoky fog due to its opacity, and odor. The word was then intended to refer to what was sometimes known as pea soup fog, a familiar and serious problem in London from the 19th century to the mid-20th century. This kind of visible air pollution is composed of nitrogen oxides, sulfur oxide, ozone, smoke and other particulates.
PeloponneseThe Peloponnese (ˌpɛləpəˈniːz,_-ˈniːs), Peloponnesus (ˌpɛləpəˈniːsəs; Pelopónnēsos, peloˈponisos), or Morea is a peninsula and geographic region in southern Greece. It is connected to the central part of the country by the Isthmus of Corinth land bridge which separates the Gulf of Corinth from the Saronic Gulf. From the late Middle Ages until the 19th century, the peninsula was known as the Morea (Μωρέας, Morèas), a name still in colloquial use in its demotic form (Μωριάς, Moriàs).
PisistratusPisistratus, Peisistratus or Peisistratos (Πεισίστρατος ; 600–527 BC) was a politician in ancient Athens, ruling as tyrant in the late 560s, the early 550s and from 546 BC until his death. His unification of Attica, the triangular peninsula of Greece containing Athens, along with economic and cultural improvements laid the groundwork for the later pre-eminence of Athens in ancient Greece. His legacy lies primarily in his institution of the Panathenaic Games, historically assigned the date of 566 BC, and the consequent first attempt at producing a definitive version of the Homeric epics.
