The book An Essay on the Principle of Population was first published anonymously in 1798, [1] [2] but the author was soon identified as Thomas Robert Malthus. The book predicted a grim future, as population would increase geometrically, doubling every 25 years, [3] but food production would only grow arithmetically, which would result in famine and starvation, unless births were controlled. [3] The book overlooked potential improvements in farming such as steam-powered machines, [3] chemical fertilizers, drip irrigation , night lighting, or genetically modified organisms (GMO). [3]

While it was not the first book on population, it was revised for over 28 years and has been acknowledged as the most influential work of its era. Malthus's book fuelled debate about the size of the population in the Kingdom of Great Britain and contributed to the passing of the Census Act 1800. This Act enabled the holding of a national census in England, Wales and Scotland, starting in 1801 and continuing every ten years to the present. The book's 6th edition (1826) was independently cited as a key influence by both Charles Darwin and Alfred Russel Wallace in developing the theory of natural selection.

    Could research this but right off the top of my head the Exxon-Valdez disaster comes to mind.. http://en.wikipedia.org/wiki/Exxon_Valdez_oil_spill They could/should have double hulled vessels long before it became mandatory, a couple decades after the disaster not all United Statesian oil transports are double hulled yet, although they will be soon, but that is because it is mandated by law as of 2010 I think.

    Introduction Earthquake is a terrible kind of natural calamity. where earthquake occurs the earth shakes. If the earth shakes violently, the result is disastrous. Man may escape other kinds of calamity. But if earthquake occurs, there is no way out. Cause The interior of the earth is full of hot liquid. This liquid has been cooling at its surface. When its surface cools and contracts earth upon it is drawn downward. The earth upon it cracks in the process. When the water from a sea passes down through the crack and touches the hot liquid. It gives rise to a mass of steam. When the steam expands and dashes to come out, the earth is violently shaken. Thus happens the earthquake. The steam under the earth finds an easy way out through a volcano. So, the land, which is full of volcanoes is frequently infested by earthquakes. Through these volcanic explosions come out fire, smoke, steam and liquid substance called larva. Devastation When earthquake happens, the earth comes under a terrible convulsion. Huge castles and buildings are violently shaken. They breakdown beating a lot inmates inside them. A lot of forge trees shake violently and get uprooted. Things are tossed. People cannot stand upright. They cannot walk. They cannot run and they cannot lie down. They, too are tossed like the movable. Water in ponds and rivers is thrown upward. Sometimes they rush off their beds and flow elsewhere. The water in lakes and seas get highly upsurge. Fire tosses off the heavens and it burns the settlements. Rivers dry up and mountains sink down. Earthquake makes a heavy loss of life and property. Crops are ruined. Stores are destroyed. Famine breaks out. Within a few minutes beautiful cities full of palatial buildings lie waste like a war-ravaged country. The men who were, a few minutes back, boasting of their wealth and pride, are found moving about with begging bowls in their hands. Conclusion Earthquakes are not new to the world. It is a very common thing on many parts of the earth. Japan is the constant victim of earthquakes. So, the Japanese make houses of paper boards. India, too is not altogether free from this natural calamity. But in India, it is very few and far between. In 1993 Maharastra had faced a terrible shock from a divesting earthquake and the Latoor are was completely damaged. Earthquake cannot be prevented. They catch up by surprise. Hence, let us wait for the scientific developments that may find a remedy to this terrible upsurge.
