Ancient India: Geography and Early Settlements

In northern India, the Brahmaputra, Ganges, and Indus rivers carry rich silt from the mountains to the plains. India’s early settlers farmed and later built walled settlements in these fertile river valleys, marking the beginning of civilization in India.

In some parts of the Deccan Plateau in southern India, rich black soil is ideal for growing cotton.

The Eastern and Western Ghats are located near India’s coasts. The Western Ghats are notably higher and wetter than their eastern counterparts. Along India’s northern border lie the Himalayas, the highest mountains in the world. The Hindu Kush range, running through present-day Pakistan, provides crucial access to the Indian subcontinent via... Continue reading "Ancient India: Geography, Empires, and Cultural Milestones" »

The Spanish Housing Bubble (1997-2006)

The housing bubble occurred in Spain during the decade from 1997 to 2006. During this period, housing prices effectively doubled. Property prices grew significantly faster than the prices of other goods.

According to Gandoy, in comparison with the European Union, construction achieved significant importance in Spain. This housing expansion formed the basis of the economic growth model, driven by demographic growth resulting from immigration and the demand for secondary residences from both national investors and other Europeans. Housing demand rose thanks to easy credit availability stemming from lower interest rates. Prices were further accelerated by the supply of buildings driven by speculation, which...

Mental health is something very important to which we give too little importance. The pandemic has increased mental illness exponentially.

The pandemic has been very hard for everyone, and as a result of this and other situations like stress or work pressure, there are more people with mental illnesses such as depression or anxiety. It is therefore very important to ask for help, normalize the situation, and go to a psychologist. There should also be a change at the legislative level, as many people cannot afford to pay a psychologist and therefore are not treated.
