Kung ating susuriin, ang ating planetang Earth ang tanging planeta sa buong Solar System or maging sa buong Universe ang may BUHAY. Ibig sabihin nito, lahat ng may buhay ay dito nakatira: tao, hayop, halaman, at maging mga maliliit na mga nilalang tulad ng bacteria at mga insekto. Sa pagdaan ng maraming taon at centuries, di natin namamalayan na ang bilang ng nilalang (pati rin AKO) na nabubuhay sa Earth ay parami ng parami. Kung ating tatanungin, what is the exact or rather approximate number of population of the world?
In fact, according to the United Nations (UN), in the book "2010 Revision of the World Population Prospects", world population has reached 7 BILLION on October 31, 2011. Ganyan na tayo karami sa ngayon. In addition, world population had reached 6 BILLION noong 1999 lang. Then after 12 years, according to the United Nations the 6 billions figure was reached on October 12, 1999 (celebrated as the Day of 6 Billion). So, when will world population reach 8 BILLION? According to the same source, it will happen that by the year 2027.
I have read an article from yahoo website that beyond our Solar System, there is an earth-sized planets discovered. Here is the whole article that I want to repost here in my blog.
