Earth has been house to life for millions of years. When we speak of life on earth, most exotic topic that comes to our minds is of Dinosaur reptiles. Many movies have been produced featuring different species of dinosaurs. It seems like this was the first form of life that appeared on earth but this is not true. Earth was house of life even before appearance of dinosaurs. After passing through millions of evolutionary years and processes earth witnessed the birth of mankind. With the arrival of human, a new era started on earth. At the start of human race, environmental conditions were very harsh. To cope up with these harsh conditions, human made use of greatest tool ever used or developed by all species on earth. Name of that tool is science. At the beginning there was little knowledge of different things happening around the humans. As the time passed more and more knowledge regarding the environment was accumulated that lead to series of inventions and discoveries. These inventions made things easier for humans. One such example is related to fire. When there was no concept of fire, humans faced many problems to keep themselves warm in cold weather. Once the process of igniting and maintaining fire was established, keeping warm inside a cave became much more easy. After discovering insulating capacity of different material, and use of these materials to cover bodies lead to even more comfortable winters. There is very long list of these discoveries that lead to modern day life style of humans on earth. We will discuss some of these discoveries in some other post. After so many discoveries and years of presence on earth human are still facing challenges to live on earth. One of the biggest challenges in modern area is food security. With continuous increase in population and reduction in agricultural land has created food crisis. In this grave challenge, again, science is helping us to overcome this problem. Though problem of food security has not been solved completely but there is tremendous increase in food production from same old agricultural land. New animal farming techniques are being developed in order to maximize meat and milk production in least possible time. Most recent attempt in this regard is lab grown meat. Though it seems very strange concept but scientists are working vigorously on this idea. If , one day, we are able to grow meat in lab, will you be the one who oppose such developments or will you promote such projects for protein shortage to come to an end. As for agricultural products are concerned multi layer farming is being introduced to increase production many folds. As these new methods give us hope to over come food crisis in future, there is still time to witness effectiveness of these methods. Only time will tell if science will again be saviour of man kind in this new challenge.
