As plants take in carbon dioxide for
photosynthesis, they release water
through evapotranspiration from their leaf pores, which helps them cool down in the hot sun, much as
human sweat cools us down.
Human civilization has depended on our ability to «gather» solar energy
through photosynthesis for millennia — this is called «agriculture» — and today's solar thermal and photovoltaic technologies make it VERY easy to gather solar energy for electricity, water and space heating, etc..
