Now, this may seem surprising, as 75 percent of our planet is covered in water, but only 2.5 percent of that is freshwater, and less than one percent of Earth's freshwater supply is available for human consumption.
Nah, ini tampak mengejutkan, karena 75% Bumi tertutup air, tapi hanya 2,5%-nya air bersih, dan kurang dari 1% persediaan air bersih di Bumi tersedia untuk dikonsumsi oleh manusia.
