CHAPTER II — Pop­u­la­tion Cen­ters, Tem­per­a­tures and Cli­mate describes Mars as a world of remark­able con­trasts, with a pop­u­la­tion of 13.16 bil­lion peo­ple spread across a vast expanse of hab­it­able land. This is in sharp con­trast to Earth, where just 1.645 bil­lion peo­ple occu­py less land, in part due to the large oceans that dom­i­nate Earth­’s sur­face. Mars, on the oth­er hand, uses almost its entire land­mass for habi­ta­tion and agri­cul­ture, with the few excep­tions being swampy areas and the polar ice caps. The exten­sive canal sys­tem, vis­i­ble even through tele­scopes from Earth, plays a cru­cial role in Mars’ abil­i­ty to sup­port its vast pop­u­la­tion, enabling the plan­et to imple­ment an advanced and high­ly inten­sive form of agri­cul­ture that exceeds the farm­ing tech­niques used on Earth.

Mars’ cli­mate is marked­ly dif­fer­ent from Earth­’s, yet it is suit­able for sus­tain­ing life, despite extreme tem­per­a­tures that can plunge to as low as 80 degrees below zero dur­ing win­ter. The plan­et’s year lasts 687 days, which means the longer sea­sons pro­vide extend­ed peri­ods of tem­per­ate weather—particularly dur­ing spring, sum­mer, and autumn. These milder con­di­tions allow Mar­tians to grow mul­ti­ple crops each year, ensur­ing that food scarci­ty is nev­er an issue. Rather than rely­ing on exten­sive irri­ga­tion sys­tems like those on Earth, Mar­t­ian agri­cul­ture adapts to the planet’s unique atmos­phere. The Mar­tians employ dew­fall, a nat­ur­al process that col­lects mois­ture from the atmos­phere, to irri­gate their crops, a method suit­ed to the rapid evap­o­ra­tion rates and thin­ner atmos­phere that char­ac­ter­ize their plan­et.

Mars’ atmos­phere, while breath­able, presents sig­nif­i­cant chal­lenges for its inhab­i­tants, pri­mar­i­ly due to its low air pres­sure, which mea­sures just 8 pounds per square inch com­pared to Earth­’s 15. As a result, Mar­tians have evolved unique phys­i­o­log­i­cal traits that allow them to thrive in this envi­ron­ment, includ­ing the abil­i­ty to func­tion with­out requir­ing spe­cial­ly adapt­ed lungs. This adap­ta­tion is essen­tial for sur­vival, under­scor­ing the role of divine guid­ance and effi­cien­cy in Mar­t­ian life, where every resource is care­ful­ly uti­lized for opti­mal out­put. Despite these chal­lenges, the Mar­t­ian pop­u­la­tion has flour­ished, with lit­tle to no need for spe­cial­ized envi­ron­men­tal pro­tec­tion, as their bod­ies are well-suit­ed to the con­di­tions.

In addi­tion to the low atmos­pher­ic pres­sure, Mars ben­e­fits from a remark­ably sta­ble cli­mate. The plan­et does not expe­ri­ence the extreme wind­storms, light­ning, or mag­net­ic dis­tur­bances that often char­ac­ter­ize Earth­’s envi­ron­ment. Instead, Mars enjoys clear skies, rare rain­fall, and gen­tle breezes that fos­ter a peace­ful exis­tence for its peo­ple. This serene cli­mate con­tributes to a har­mo­nious soci­ety, where farm­ing is pro­duc­tive, and the envi­ron­ment sup­ports both the land and its inhab­i­tants. Unlike Earth, which is often plagued by envi­ron­men­tal and soci­etal tur­bu­lence, Mars is por­trayed as a world of tranquility—where inno­va­tions in farm­ing and col­lec­tive soci­etal efforts con­tribute to a sta­ble, pros­per­ous exis­tence for its peo­ple.

What fur­ther dis­tin­guish­es Mars from Earth is the absence of vio­lent weath­er pat­terns and the min­i­mal dis­rup­tion to its inhab­i­tants’ dai­ly lives. The calm­ness of the Mar­t­ian cli­mate is vital for sus­tain­ing the plan­et’s high pop­u­la­tion den­si­ty, ensur­ing that its agri­cul­tur­al sys­tems can oper­ate with­out the inter­fer­ence of severe storms or nat­ur­al dis­as­ters. While Earth con­tin­ues to strug­gle with issues like droughts, floods, and unpre­dictable weath­er, Mars offers a pre­dictable and con­sis­tent envi­ron­ment that enables its peo­ple to focus on pro­duc­tiv­i­ty and growth. The Mar­t­ian approach to sus­tain­abil­i­ty is built around the reli­able use of the plan­et’s resources, from water man­age­ment via canals to the adap­ta­tion of farm­ing meth­ods for an atmos­phere that dif­fers vast­ly from Earth­’s.

In sum, the cli­mate and atmos­phere of Mars con­tribute to a unique, thriv­ing envi­ron­ment where the Mar­t­ian pop­u­la­tion not only sur­vives but flour­ish­es. By har­mo­niz­ing with the nat­ur­al ele­ments and devel­op­ing an effi­cient use of resources, Mars has over­come the chal­lenges posed by its extreme tem­per­a­tures and low air pres­sure. This chap­ter show­cas­es how the peo­ple of Mars, through care­ful plan­ning and col­lec­tive effort, have cre­at­ed a sta­ble and abun­dant world—a stark con­trast to Earth­’s often unpre­dictable cli­mate and the envi­ron­men­tal strug­gles that shape its own soci­eties.
