Most of the people who are living today (other than those in the developed countries and those in the middle and upper classes in other countries) have been born not because of their wish or because their parents wanted them.

They have been born as byproducts of the natural biological process called sexual reproduction.

Nature has a Program by which a male and a female (once they attain teen age) are drawn towards each other with the end result of bodily satisfaction to one or both of them while implanting of an embryo in the body of the female (which will eventually become an element in the next generation).

Unfortunately when the nature draws a male or female homosapien towards each other, it does not choose partners who are physically and psychologically fit at the time of their coitus to produce a healthy offspring. As such, children are born to physically fit parents as well as to those who are unfit to produce children (due to hereditary as well as lifestyle impairments). Also the present day’s children who are born to wealthy and middle class parents become sick (afflicted by juvenile diabetes, obesity, hypertension, visual impairment etc.) at very tender ages thanks to their non – healthy eating habits and sedentary life styles planted in them (and their parents) by the liberalized mass media.

However, in accordance with human rights that we value, and thanks to the superior developments in the fields of medicine, advance communication facilities and the disaster management facilities, we are able to physically and medically save many lives of whom are those subjected to disease and disasters. The end result is the explosion of population and also the rapid increase of the number of dependant persons (socially and economically inactive persons) who are to be supported by others persons (active persons).

Just imagine what would have happened if all the coituses that happen day and night ended up with new fetuses? We would not have had even standing space on the earth surface!!!

As we know, out of the earth surface, the habitable portion is only about 10 %. In Sri Lanka, out of the total land extent, homesteads account for about 800,000 ha out of the total of 6,650, 000 ha. This is about 12 % of the gross area. According to 2013 census, Sri Lanka population was 20.43 million. Hence, per capita homestead extent is about 0.04 ha (i.e. about 400sqm per capita). Prior to advent of the industrial era in the 1900, the population has been about 4, million and in the year 1950, it had been 7.7 million and per capita homestead extents had respectively been 0.2 and 0.1 ha approximately.

Thanks to pipe borne water, grid electricity, advanced road networks, modern communication systems etc. many marginal lands that were practically uninhabitable half a century before, have become habitable by and by. Hence, due to shortage or non affordability of habitable land, the successive generations who became landless were moving into lands that have been lately made habitable by human intervention. Nobody cared for this harmful process, by taking the nature for granted. Although the nature has silently bared such interventions, it is wrong to take for granted that the humans have won over the nature. Nature has its own ways and means of retaliating with vengeance, by way of creating calamities, some of which are foreseeable and the others are not so. In that sense, it can be seen that even during good old days (prior to advent of industrial era), the nature has had ways and means of keeping men and animal populations under check and balances by appropriate intervention.
