Fossil footprints

Marine fisheries of India has been witnessed with substantial increase of fishing effort and fishing efficiency during the last five decades which resulted in overexploitation of fish stocks together with the increase of fossil fuel burning and CO2 emission into the atmosphere. The present study covered three important fishing harbours of Kerala to reveal an estimation of CO2 footprint (considering the emission of CO2 only during the fishing operation) by the mechanised fishing trawlers which showed a considerable higher value than the previous studies.

PHILOSOPHY.--The aim of philosophy is to seek the explanation of all things: the quest is for the first causes of everything, and also how all things are, and finally why, with what design, with a view to what, things are.

Laetoli in northern Tanzania is one of the most important paleontological and paleoanthropological sites in Africa. It is renowned for the recovery of early hominin fossils belonging to A. afarensis and for the discovery of remarkably well-preserved trails of footprints of hominins. Given the significance of Laetoli for understanding and interpreting the evolutionary history of early hominins the author initiated long-term geological and paleontological investigations at Laetoli and at other fossil localities on the Eyasi Plateau.
