Human & Environment Interactions
Environment → Human

=Monsoons= Monsoons are seasonal reversing wind that carries rainfall. In summer, monsoon brings heavy downpours, but little rain at other seasons. However, rivers of South Asia—Indus, Gages, Brahmaputra rivers—floods many time and it makes the soil more fertile, eventually suitable for farming.

Occasional monsoons cuts networks of steep-sided gullies into alluvial deposits. Ganges and Brahmaputra rivers join together to form a delta of low-lying. This land, which occupies most of Bangladesh, becomes very floodable. These plains then are used for farming intensely.

=Himalayas= Himalayas is a mountain range in South Asia, which separates Indian subcontinent from the Tibetan plateau. It is a home for world's tallest mountains, including Mount Everest. This mountain range act as a blocker of freezing air coming from central asia. Therefore, winter in south asia is very warm and dry, unlike how it's summer is unbelievably hot and humid.

== =Ganges river= Gang es river has great religious significance for Hindus. They treat this river very holy and often bath in it, because bathing in Ganges river is believed to be forgiving of one's sins. People also drink from it and carry it to their home after filling their pots with water and most temples are lined with the river.

=Earthquakes= Earthquakes of south asia had helped it's distinct shape to be formed. For example, Himalayas was the product of an earthquake by clashing plates. However, earthquake led to loss of many lives, properties, and so one. At Latur, Maharashitra, in 1994 and Bhuj, Gujarat, in January 2001. It had caused loss of lives, houses, and properties.

Human → Environment

=Air pollution= As usage of herbicides and pesticides for farming increased, number of factories of toxic concentrations and chemical elements increased also. In 1984, at the Union Carbide pesticide plant in Bhopal, India, water leaked into a methyl isocyanate storage tank. Inside the tank where water and the chemical had triggered reaction, toxic gases were produced. It spread all over the areas and had killed 3000 people immediately and another 12,000 as time went by. However, the real number of people injured has been proven to be at least 50,000 with long term effects on eyes, lungs, and immune system. It destroyed farming livelihoods and the smell of the place worsened.

= = = = = = = = =Water pollution= As economies of some places grew stronger, the number of factories increased. Some of those factories had let a polluted concentration of leather tanning works to enter Ganges river. People who were bathing in the Ganges river as a Hindu ritual began to have health problems, because of the river's polluted water. In recent years, the pollution had worsened because of uprising trashing in the Ganges and funeral pyres along it's banks. There are 264 million gallons of human waste per day.

=Deforestation= Humans had cut down forests to get woods and acquire places further on their nation's developments(buildings, cultivated area). Area of forests has decreased. From that deforestation, flood can occur because trees drink water and hold it. So at lower Ganges and Brahmaputra valleys and combined delta, huge flood had occured because of deforestation of upper reaches of rivers and their tributaries in India, Nepal, and Tibet. lower Ganges and Brahmaputra valleys/ combined delta

=Natural resources= Natural resources of south asia strengthened India's economy. These resources include: oil, natural gas, iron ore, coal deposits, diamonds and many others.
