THE CRA PERSPECTIVE • EARTH SCIENCE How Much Water Is There on Earth? Can our planet ever run out of water? Exploring Earth's enormous water reserves, the freshwater shortage and the future of humanity. Water is one of the most extraordinary and essential resources on our planet. Our planet is called the Blue Planet for a reason. Approximately 71% of Earth's surface is covered by water. But does that mean we have an unlimited supply of water for human survival? Look at the oceans, rivers, lakes, glaciers and countless streams across the world. Water seems almost endless. It falls as rain, flows through rivers, disappears into the ground, freezes into ice and rises into the atmosphere as water vapour. Yet billions of people experience water shortages.

Introduction
Jallikattu is an ancient sport. The seals of the Indus Valley civilization
depict it, which is proof that this sport was in vogue 5,000 years ago. Ancient
Tamil poetry, known as Sangam literature (2nd BCE – 2nd CE), has many detailed
references to Eru Thazhuvuthal (hugging the bull).
History
Jallikattu also known as Eru thazhuvuthal is one of the traditional sport in
which a Bos indicus bull is released into a crowd of
people. Multiple human participants attempt to grab and tightly "hug"
the large hump of the bull and hang on to it while the bull attempts to escape.
Participants hug the hump for as long as possible, attempting to bring the bull
to a stop. In some cases, participants must ride long enough to remove flags
affixed to the bull's horns. Jallikattu
is typically practiced in the Indian state of Tamil
Nadu as a part of Pongal celebrations on Mattu Pongal day.
