I need to make a speech about water can I have some help

Water;the most important thing on earth, we use it to survive. Though there is not much of it to drink, there is a bunch of salt water. If we do not have water we will die. ( please don’t use this, it’s late and I wanna help so just use the idea, not the paragraph)
