Seen from space, the images of our planet show that the Earth is blue, since 70% of its surface is covered by water and only the remaining 30% corresponds to the mainland.
However, of this seventy percent of water, <em>97% of it corresponds to the water found in the oceans, so it is liquid salty water</em>. The remaining three percent is divided into f<em>rozen waters, which corresponds to 2%</em> and the <em>water available for human consumption and the ecosystems that inhabit the planet is 1%.</em>
