What's one cause of the heat island effect?

urbanization and natural surfaces by build surfaces causes the heat island effects and is also in toyko

 The correct answer is :  The heat island effect occurs when people cover the green areas and the earth with buildings and roads, there is a change in the climate, the earth and the atmosphere. When the terrain is covered with these types of structures, the thermal conditions of the surrounding atmosphere are modified. Buildings release heat through machines or gas emissions, among others. To the effect of heat island also contribute the high buildings, the lack of evaporation in a city, the pollutants of the industrial processes, the cars with internal combustion engine, air conditioning units, among others.

the answer would be voluntary exchange -

"the act of buyers and sellers freely and willingly engaging in market transactions. moreover, transactions are made in such a way that both the buyer and the seller are better off after the exchange than before it occurred."
