The Great Desert Where Hippos Once Wallowed
The Sahara sets a standard for dry land. It’s the world’s largest desert. Relative humidity can drop into the low single digits. There are places where it rains only about once a century. There are people who reach the end of their lives without ever seeing water come from the sky.
Yet beneath the Sahara are vast aquifers of fresh water, enough liquid to fill a small sea. It is fossil water, a treasure laid down in prehistoric times, some of it possibly a million years old. Just 6,000 years ago, the Sahara was a much different place.
It was green. Prehistoric rock art in the Sahara shows something surprising: hippopotamuses, which need year-round water.
“We don’t have much evidence of a tropical paradise out there, but we had something perfectly liveable,” says Jennifer Smith, a geologist at Washington University in St Louis.
The green Sahara was the product of the migration of the paleo-monsoon. In the same way that ice ages come and go, so too do monsoons migrate north and south. The dynamics of earth’s motion are responsible. The tilt of the earth’s axis varies in a regular cycle — sometimes the planet is more tilted towards the sun, sometimes less so. The axis also wobbles like a spinning top. The date of the earth’s perihelion — its closest approach to the sun — varies in cycle as well.
At times when the Northern Hemisphere tilts sharply towards the sun and the planet makes its closest approach, the increased blast of sunlight during the north’s summer months can cause the African monsoon (which currently occurs between the Equator and roughly 17°N latitude) to shift to the north as it did 10,000 years ago, inundating North Africa.
Around 5,000 years ago the monsoon shifted dramatically southward again. The prehistoric inhabitants of the Sahara discovered that their relatively green surroundings were undergoing something worse than a drought (and perhaps they migrated towards the Nile Valley, where Egyptian culture began to flourish at around the same time).
“We’re learning, and only in recent years, that some climate changes in the past have been as rapid as anything underway today,” says Robert Giegengack, a University of Pennsylvania geologist.
As the land dried out and vegetation decreased, the soil lost its ability to hold water when it did rain. Fewer clouds formed from evaporation. When it rained, the water washed away and evaporated quickly. There was a kind of runaway drying effect. By 4,000 years ago the Sahara had become what it is today.
No one knows how human-driven climate change may alter the Sahara in the future. It’s something scientists can ponder while sipping bottled fossil water pumped from underground.
“It’s the best water in Egypt,” Giegengack said — clean, refreshing mineral water. If you want to drink something good, try the ancient buried treasure of the Sahara.

Read the following passage carefully and answer the following questions.
Pollution is the introduction of contaminants into the environment that cause harm to the ecosystem. The different kinds of pollution are air pollution, water pollution and land pollution. The release of various gases, finely divided solid particles, or liquid droplets that escape into the atmosphere to disperse and dilute in the environment is called air pollution. Modern society is also concerned about specific types of pollutants, such as noise pollution, light pollution, and plastic pollution.
Particulate Matter (PM), also known as particle pollution, is a complex mixture of extremely small particles and liquid droplets that get into the air. These particles if inhaled can affect health. The impact of PM 2.5 is particularly high in South Asia. Outdoor pollution is caused by a variety of pollutants like public and private vehicles, waste burning in the open, power production industries and construction and even cigarette smoking in public places.
Presently, air pollution is a major and growing risk factor for ill health in India. Delhi is one of the most air polluted cities in India. The air in the city as well as areas surrounding it has worsened to extremely hazardous levels in the recent years. This year’s pollution level is the worst in four years. Several studies have shown that poor air quality is a cause for many health issues among people with lower respiratory disorders with symptoms like dry cough, breathlessness, wheezing, chest discomfort, serious lung infections and cardio vascular diseases. Some studies throw light on the fact that about 16 per cent of the deaths worldwide in 2015 were due to pollution.
Air Masks are an option to protect oneself outdoor. Air masks can be used while commuting or while one is exposed to a polluted area. Some of these masks also include a layer of Activated carbon to filter the air. They protect us from suspended air particles and particulate matter up to the size of 2.5 microns and above. Their usage is limited to some days and should be disposed off after their prescribed duration of usage. The price for air masks starts from Rs 100 and can go up to Rs 500 and more.
