If the whole world have the same temperature colour based racism would disappear since colour is the function of melanin, which itself is a function of ambient temperature. The same temperature of the world would produce the same skin colour
 
 agree or disagree ?

 

Disagree.  There is only one variety of Homo Sapiens, so race is a meaningless distinction.  Melanin is a skin pigment to protect against exposure to ultraviolet radiation.   Exposure to ultraviolet radiation is less in colder climates due to more clothing as humans migrated toward the poles, so melanin is largely irrelevant.  Skin tone being a function of ambient temperature is illogical since dark skin in equatorial regions would absorb more heat (infrared radiation) where it is needed least, while light skin in higher latitudes would reflect more heat where it is needed most.

Interbreeding, organ transplants, and blood transfusions are possible between humans of different skin color therefore we are one species regardless of superficial exterior features.  For example:

 

"Woods was born in 1975 in Cypress, California,[13] to Earl[14] and Kultida "Tida" Woods.[15] He is their only child and has two half-brothers, Earl Jr. and Kevin, as well as a half-sister named Royce from his father's first marriage.[16]

Kultida (née Punsawad) is originally from Thailand, where Earl had met her on a tour of duty in 1968. She is of mixed Thai, Chinese, and Dutch ancestry.[17] Earl was a retired lieutenant colonel and Vietnam War veteran who was mostly African American with traces of European descent. Earl's mother Maude Carter was light skinned. Some people suggested that she had Native American and Chinese ancestry.[18] Tiger refers to his ethnic make-up as "Cablinasian" (a syllabic abbreviation he coined from Caucasian, Black, American Indian, and Asian).[19]"

Not to derail the discussion, but why is golf even considered to be a sport?  Now if  they added people armed with tennis rackets to block putts at each hole and allowed tacklers at the tee it might be a sport.  8P

I think it would be more fun and competitive to have skeet shooters try to shoot the drives out of the air.

 

Instead of tennis rackets to block putts, just let the golfers putt to intercept and block each other's putt.

 

It would be a lot more entertaining.

Which is indeed why polar bears have black skin and when the sun comes back they can move their fur to let in more light (or at least so I was told when in Svalbard)
