There are three main groups of oils-animal, vegetable and mineral. Great quantities of animal oil come from whales, creatures of the sea, which are the largest of the animals remaining in the world. To protect the whales from the cold of the Artic seas, nature has provided them with a thick covering of fat, called blubber. When the whale is killed, the blubber is stripped off and boiled down. It produces a great quantity of oil which can be made into food for human consumption. A few other creatures yield oil, but none so much as the whale.

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.
