How To Reduce Your Carbon Footprint.

Here is a practical list of 15 ways to reduce our personal and corporate carbon footprint. What do we mean by ‘a carbon footprint?’ A carbon footprint is defined as the total amount of greenhouse gases produced to directly and indirectly support human activities, usually expressed in equivalent tons of carbon dioxide (CO2). In other words: When you drive a car, the engine burns fuel which creates a certain amount of CO2, depending on its fuel consumption and the driving distance. When you heat your house with oil, gas or coal, then you also generate CO2. Even if you air-conditioned your house with electricity, the generation of the electrical power may also have emitted a certain amount of CO2. When you buy food and goods, the production of the food and goods also emitted some quantities of CO2. Your carbon footprint is the sum of all emissions of CO2, which were induced by your activities in a given time frame, usually for the time period of a year. For example, each of the following activities add 1 kg of CO2 to your personal carbon footprint:

Travel by public transportation (train or bus) a distance of 10 to 12 km (6.5 to 7 miles);
Drive with your car a distance of 6 km or 3.75 miles (assuming 7.3 litres petrol per 100 km or 39 mpg);
Fly with a plane a distance of 2.2 km or 1.375 miles;
Operate your computer for 32 hours (60 Watt consumption assumed);
Production of 5 plastic bags;
Production of 2 plastic bottles; and
Production of 1/3 of an American cheeseburger (yes, the production of each cheeseburger emits 3.1 kg of CO2!).

Tajik is a general designation for a wide range of native Persian-speaking people of Iranian origin, with current traditional homelands in present-day Tajikistan, Afghanistan and Uzbekistan. Not all Tajiks speak a variety of modern Persian. They may speak any one of the extant Iranian languages. For example, the Tajiks of China are actually Pamiris and speak the Eastern Iranian Pamiri languages and are distinct from more western Tajiks. They are concentrated in the Oxus Basin, the Farḡāna valley (Tajikistan and parts of Uzbekistan) and on both banks of the upper Oxus, i.e., the Pamir Mountains (Mountain Badaḵšān, in Tajikistan) and northeastern Afghanistan and western Afghanistan (Badaḵšān, Kābol, Herat, Balkh, Mazar-i-Sharif, Ghazni and other urban regions). Historically, the Tajiks were initially agriculturalists but urbanized rather early in ancient times as indicated by their role in the history of what later became Greater Khorasan. Several surviving ancient urban centres of the Tajik people include Herat, Samarkand, Bukhara, Khujand, and Kabul.

Planetary Nebula NGC 2438.
Image Credit & Copyright: Daniel López, IAC. NGC 2438 is a planetary nebula, the gaseous shroud cast off by a dying sunlike star billions of years old whose central reservoir of hydrogen fuel has been exhausted. About 3,000 light-years distant, it lies within the boundaries of the nautical constellation Puppis. This image of NGC 2438 highlights a halo of glowing atomic gas over 4.5 light-years across, extending beyond the nebula's brighter inner ring. Similar haloes have been found in deep images of other planetary nebulae, produced during the earlier active phases of their ageing central stars.

The current flag of Myanmar was adopted on 21 October 2010. The new flag was introduced along with implementing changes to the country's name, which were laid out in the 2008 Constitution. The design of the flag has three horizontal stripes of yellow, green and red with a five-pointed white star in the middle. The three colours of the stripes are meant to symbolise solidarity, peace and tranquility, and courage and decisiveness. The white star that symbolised the Union of Burma.

The Elgin Marbles are a collection of Classical Greek marble sculptures made under the supervision of Phidias and his assistants in c. 447 to 438 BC; originally part of the temple of the Parthenon. From 1801 to 1812, agents of Thomas Bruce, 7th Earl of Elgin removed about half of the surviving sculptures and transported them to Britain. The half not removed is now displayed in the Acropolis Museum. In Britain, the acquisition of the collection was not supported by some, and the Earl's actions was likened to vandalism. Following a public debate in Parliament and its subsequent exoneration of Elgin, he sold the Marbles to the British government in 1816. They were then passed to the British Museum, where they are now on display in the purpose-built Duveen Gallery.
