We can say that life has a tendency to continue to multiply, no matter what, even if that means to radically change its nature. In fact, the oldest-known individual tree is a bristlecone pine from California that is more than 5,060 years old. Road enthusiasts have calculated that there are 425,000km (264,000 miles) of public road in Britain (including 3,590km of motorway and nearly 57,000km of A road). After a long time, it is believed that the Earth’s temperature would rise to at least 290 degrees Celsius (554 °F). Ironically, 'phonetics' is pretty difficult to spell, since it sounds like it begins with an "F.". This question is a hypothetical one, which is what makes it so ironic. Yet here we are, and studies indicate that in our time, biodiversity has expanded more than ever, at an exponential scale. It allows our most engaged readers to debate the big issues, share their own experiences, discuss And it is estimated that, at any given time, there are five nonillion bacteria in the world—that’s a “5” followed by 30 zeros.
