The Vast Treasure Dissolved In The World’s Oceans

Image
Gold Hidden Within Ocean Water: Scientists estimate that the world’s oceans contain about 20 million tons of dissolved gold. This gold is not visible to the human eye because it exists in extremely small amounts mixed throughout seawater. The oceans cover more than 70 percent of Earth’s surface, including major bodies of water such as the Pacific Ocean and the Atlantic Ocean. Because these oceans hold an enormous volume of water, even tiny traces of gold add up to a large total amount. If all this gold could somehow be collected, its value would reach well over one trillion dollars based on current market prices.

Earth’s Lost Majority Of Life

A Planet With A Long Memory: Earth is about 4.5 billion years old, and life has existed on it for more than 3.5 billion years. During that time, countless species have appeared, evolved, and disappeared. Scientists estimate that more than 99.9% of all species that ever lived on Earth are now extinct. This means nearly all forms of life that once existed no longer survive today.
