Have you ever wondered if there is more hair on people ’s heads or blades of grass covering the earth ? It ’s an interesting question to ponder when thinking about the immense issue of humanity in the world versus the seemingly eternal expanses of grassy orbit After dive into some research on pilus counts per person and approximation of global grass blade , the answer becomes decipherable Read on to discover out whether hair or dope is more abundant on our major planet .
Estimating the Number of Hair Strands Per Person
To start this comparison , we first need to forecast the average numeral of hair on a human head . consort to research the average someone has around 100000 to 150,000 hairs on their head . However , haircloth counts vary dramatically across the great unwashed based on age , gender , and genetics .
Here ’s a breakdown of guess hair numeration by demographic :
As we senesce , hair Strand fall out and are not supplant , leading to cutting hair . By eld 50 , one-half of one ’s original whisker will be gone . Despite haircloth loss , let ’s expend the mellow end estimation of 300,000 fuzz per someone to keep the maximal potential number of hairs in our calculation .
Calculating Total Global Hair Strands
The next tone is determining the universe ’s universe to multiply our per - person hair count by . accord to the most recent United Nations judge , the current global population is approximately 7.7 billion people .
If we procreate the estimated 300,000 hairsbreadth per mortal by 7.7 billion multitude , we get :
300,000 hair x 7.7 billion mass = 2.3 quadrillion hairs
That ’s 2300000,000,000,000 Strand of human hair on head word around the universe !
Estimating Blades of Grass on Earth
Now that we have an estimation for total global hairs , it ’s clip to estimate the issue of grass brand blanketing the ground . Some key facts :
lease ’s take for granted on the low end 100 blades per square column inch and calculate blades per Accho :
If grasses cover 5.29 billion acres globally , and we manifold by the 52.2 million blade per Akka estimate , we get :
5.29 billion acres x 52,272,000 blades per acre = 276 quintillion blades of eatage globally
That ’s a massive 276,000,000,000,000,000,000 blade of forage !
The Verdict: Way More Grass Blades than Hairs
Based on these estimates , there are clear far more blade of grass than hairs on human heads globally .
To summarize :
So for every 1 strand of human hair on a head , there are approximately120,000 blades of pasture .
This rough calculation distinctly shows weed dominating in terminal figure of total numbers . Even considering possible errors in the appraisal , the resultant heavily favor grass as the winner .
Why Such Vast Grasslands Exist
The fact that grasses and grassland wrap up so much of the globe ’s land surface conduct to an significant follow - up question – why is grass so abundant and widespread ?
There are a few cardinal reasons pasture flourish :
They acquire fast – libertine ontogeny allows grasses to circularize rapidly .
Tolerate graze – Grasses can bear on grow after being partially eaten by grazing animals .
Interconnected etymon systems – Underground etymon sharing allow for locoweed to expeditiously engross body of water and nutrient .
Fill wide niches – Different grass species thrive in divers environments including tundra , prairie , mountaintops , and wetland .
Human agriculture – Vast food grain crops and lawns create by humans boost sens totals .
So smoke is structured for immobile diffusion , graze resiliency , and niche variability – perfect attributes to become Earth ’s most far - reaching plant !
While human hair is impressive in its own right , grass intelligibly dominates in terms of total number and widespread area when comparing global pilus strand to grass blades .
Grasses can boom almost everywhere thanks to fast growth , graze leeway , interconnected roots , and environmental adjustment . This result in massive grassy expanses covering 20 % of kingdom and 276 quintillion grass blade – drastically outpace the estimated global total of human hair .
It ’s astonishing to think that for every unmarried hair on a human caput , there are around 120,000 leaf blade of grass on this major planet of ours . So the next time you see a sweeping expanse of locoweed , remember it represents just a tiny fraction of the countless emerald blade blanket the terra firma !
