Some parts of Sahara are fertile and rich even today
Despite being the driest part in the world, there’s still about 80000 square miles of lush oases across the desert. That means, over two percent of Sahara is covered by Oases while ease of irrigation makes another section of the desert fertile. Endless miles of Sahara near the Nile in Egypt have been transformed by irrigation.

Sahara is the hottest desert in the world. However most people think of it as a giant oven, the lack of humidity in the Sahara during summer season causes nighttime temperatures to drop steeply, often to freezing and below. But, when it comes to the hot temperatures, the Sahara generates significantly hottest temperature on the earth. The hottest recorded temperature of all time was 136 degrees Fahrenheit in Libya in 1992.
 
At present, there are about two million people in the Sahara living nomadically. This population equals to 1 person per square mile which is of 1/150th of population density of the US. But scientists believe that Sahara was habitable once upon a time and there used to be more population than what is in the present time. But in course of time, the climate of Sahara desert has gone exorbitant changes which led to the extinction of many flora and fauna, and people as well. People can hardly imagine living there due to extremely high temperature.
 
Sahara desert is known to be the home to some of the most fascinating species of animals in this planet. The animals that inhabit Sahara desert are quite unique and most of them can’t be found elsewhere in the world. Have you ever heard of Horned Vipers? These endangered species of reptiles are found in Sahara. Other interesting animals that can be found in Sahara are: Dromedary Camels, Dorcas Gazelle, Dung Beetle, The Addax Antelope, Deathstalker Scorpion, Ostrich, Monitor Lizard, Fennec Fox, and The Jerboa among others. If we look back to thousands of years ago, there used to be enough water in Sahara. So the people and animals were able to survive. Scientists have found the evidences of the existence of river animals like crocodiles. They have also discovered the fossils of Dinosaurs, Jobaria, Afrovenator, and Ouranosaurus in the Sahara desert.
 
"The largest desert in the world is Sahara!” This is what most of the students learn in their schools. But that’s not true. The Sahara is not the largest desert in the world despite what you may have learned in school. The largest desert in the world is Antarctica! Sahara is the second largest desert in the world but it’s the world’s largest HOT desert, and is getting bigger every day.
