One estimate of the total number that have ever been born is about billion. Take away the 6 billion or so still living in , and assume the average adult mass at death is 60kg, and it turns out that the mass of people who have died and returned their mass to the biosphere is about 0. Assuming the biosphere is well mixed, about 0. I came across 17 young Canada geese sitting closely together on a lake with two adult geese as minders.
Is this creche arrangement customary? I have seen this in other waterbirds: when I worked as a warden at Newborough Warren reserve in Anglesey I saw creches of more than shelducklings. There is probably little cost to the childminders and it occurs to me based on no evidence that the ducklings probably have a herding instinct.
I am not sure that they will be necessarily be related. I wonder, do non-water birds such as chickens exhibit similar behaviour? Gulls and gannets that nest in colonies and put considerable energy into raising their young show considerable aggression towards the offspring of other members of the colony — I have seen a young Herring Gull attack, kill and partially eat a smaller nestling that had lost its way.
Why do spiders set up home in car wing-mirrors? We had one that travelled to France and back with us in the summer. Why are footballers so unfit? They get tired if they have to play more than once a week, even though they spend most of a match jogging about. Tennis players often have four three-hour matches in a week, at much higher intensity.

A train station commonly station , railway station mainly British Commonwealth or railroad station mainly US is a railway facility where trains regularly stop to load or unload passenger s or freight goods. We hope that you understood the difference between a terminal and junction. Cantt: If you want to know the meaning of a cantt station in Indian Railways, we have it covered.
Cantonment stations are the stations within the Cantt area of a region. A cantt is an area of a city where the army or armed forces are stationed. Station: A railway station, train station or simply station is a place where trains stop and take passengers or freight.
There can be multiple platforms on a single railway station to hold several trains at the same time. If we talk about the largest railway station in terms of the length of platform, then it is Gorakhpur railway station in Uttar Pradesh, India. Now that you know the difference between a station and junction, you will not be confused anymore.
Read on to know more about the difference between a railway station and central. Halt: People often wonder about the difference between halt and railway station or how railway stations are different from halt stations. So, your queries will be answered here. Halt station is a type of stop where any train carrying a passenger is scheduled to stop for a given period of time. Usually all trains run on a clear line basis, if a clear line from the next station is granted, the train at that station does not have to be stopped and can be traveled from that station, but if any particular train is scheduled to stop at that station, it will be stopped for a long time.
Such stops are advertised in public timetables, so we can check with train name or number that through stops will be at the stations of the train. The basic difference between halt and railway station is that most trains do not stop at halts but they stop at railway stations.
Now check the accurate train time table with Railrestro to plan your journey in an efficient manner. Central Station: Do you know how many central stations are there in India?
Or which railway stations are called Central stations? A Central is the busiest and most important station in a city, which has multiple stations. It deals with a large number of arrivals and departures. Such stations may be the oldest, so they are called central. During the second half of the nineteenth century, central stations or central railway stations arose as railway stations that were initially constructed on the outskirts of the city centers were enveloped by urban growth and became an integral part of the city centers themselves.
Now that you know the difference between a central and junction, you can understand why there are different naming standards for railways stations in India.
