Pollution befouls the air and poisons water. Pollution induces the release of toxicants into the biosphere which makes the air unsuitable for breathing, harms the quality of water and soil, and causes the emission of substances that may cause damage to humans, plants and animals.
To cater to the needs of an increasing population, agriculture has been intensified through the use of a wide spectrum of fertilizers and pesticides. Diverse industries have been set up to produce chemicals including those that pose a danger to all life forms.

Rapid industrialisation has led to deterioration in the quality of air. Widespread use of coal and fossil fuels in industries and petroleum fuel in motor vehicles has aggravated the air pollution problem. Our atmosphere seems to have become a waste basket into which dust, noxious fumes, toxic gases and other pollutants are callously thrown.

The intensity of air pollution in Indian cities is increasing primarily due to our vintage vehicles and their poor performance. Water pollution, too has increased with the growth of our population and also that of our industries. Water pollution has acquired dangerous dimensions ever since sewage and industrial effluents have started being disposed of into the rivers.

Once considered sacred, the rivers are now turning murky and stink. It is sad that almost three-fourths of our fellow citizens have no choice but to drink filthy water. The severely polluted rivers due to mindless dumping of sewage and industrial wastes are a cause for concern not only to us humans but also to myriads of life forms that exist in water.

On the French and Italian rivier as we can no longer see the sparkling blue waters. The Mediterranean Sea is reported to be turning grey. Rivers and canals pour sewage, detergents and industrial waste into the sea; tankers flush their contents near the river or sea; bottles, rotting garbage and oil slicks are washed into the beaches. The phosphates and nitrates applied to farmlands as inorganic fertilizers, concentrate in lakes and estuaries causing algal blooms due to which wide expanses of water get choked, plants rot, oxygen is used up and fish die.

Which of the following factors is responsible for algal blooms?

A trilateral transport corridor project, inked in Tehran this week by Prime Minister Narendra Modi and the leaders of Iran and Afghanistan, has the potential to dally (1) the geopolitical map of South and Central Asia. Mr. Modi’s visit also put an end to years of ambivalence on the development of Iran’s Chabahar port on the Gulf of Oman, the focal point of the corridor project. New Delhi and Tehran had agreed in 2003 to develop the port, near the Iran-Pakistan border. But the project did not take off, mainly owing to international sanctions against Iran over its nuclear programme, but also on account of inertia in Delhi. The removal of accolade (2) after Iran’s nuclear deal has provided New Delhi an opportunity to revitalize bilateral ties. The road, rail, and port development projects, once implemented (3), will change the way India, Afghanistan, and Iran do business. For India, the projects have specific economic and strategic significance. India and Afghanistan have failed to realize the full economic potential of their friendship owing to connectivity problems. The Pakistan link between India and landlocked Afghanistan has been a/an countenance (4), given Islamabad’s tense diplomatic ties with both New Delhi and Kabul, and sometimes with Tehran too. Once the Chabahar port is developed, Indian ships will get direct access to the Iranian coast; a rail line to the Afghan border town of Zaranj will allow India a route around Pakistan. This will surely boost trade with Iran and Afghanistan. Besides, the neglected (5) free trade zone in the Chabahar area offers Indian companies a new investment destination at a well-connected port city. India has already said its companies will set up “plants in sectors such as fertilizers, petrochemicals, and metallurgy.” in the zone. It will also supply $400 million worth of steel rails to Tehran to build the railway link.
