Ocean Acidification Solutions- From Sea Weed farming to Solar Powered bio-rocks.

We live on a beautiful planet, Earth. The Earth’s surface is mostly covered by water bodies (70%), and 97% of it is oceanic water. Thus, oceans are home to many living organisms and form an important ecosystem. The optimum pH of our oceans has always been slightly basic (saline), between 8.1 to 8.2, ambient for the marine life forms to survive. But the scenario started to change post-industrial revolution. Reports state that oceans are becoming acidic, due to increasing concentrations of H+ ions. As a result, pH has now gone down to 8.06 from 8.1. Prima Facie, it seems to be…

Hydrogen Fuel- A Greener Alternative?

Hydrogen Fuel- A Greener Alternative?

Efficient energy production and supply are critical for the economic development of every nation. Our energy demands extend to every sphere of life, be it domestic, industrial, transport, etc. Therefore, energy production has always been an important industrial sector. This sector is of utmost importance for emerging economies and developing nations, as energy production and export might accelerate the country’s economic gains significantly.  Most of the energy that we consume originates from conventional energy sources such as fossil fuels. But in the wake of the current climate crisis, and fossil fuels being the top culprit, there is a search for…

Entering the human Epoch, Anthropocene.

Entering the human Epoch, Anthropocene.

Much like we have a biological clock, earth has its own geological clock, the only difference is that it spreads over millions and billions of years and our lifetime is merely a matter of seconds in it. Earth’s history is segmented into different phases based on the geological clock. The change in the geological time unit is marked by significant changes in the features such as the sedimentation pattern of rocks and fossil makeup. Thus, the study of rock strata (stratigraphy) is an important tool to find out the geological timescale shift. Another parameter considered to study the shift in…

Natural Dyes a sustainable way to fashion!

Fashion has been an integral part of human civilisation for centuries. It was in the 18th century when the pioneers of fashion design (royal dressmakers) came to light. Fashion slowly made its way to the common people and, since then, the fashion industry has been on the rising. Colour is the essence of the fashion industry. The substances used to colour any material are dyes and pigments. Dyeing is an old practice and it has its roots in the Neolithic period. Traditionally, dyeing was done using natural materials obtained from plants and animals. But, the accidental discovery of the first…
