Water is essential for life but scarce in much of Africa. The continent has diverse hydrology, from vast deserts with only seasonal rivers to huge river systems thousands of miles long. The largest lake is Lake Chad, though it is shrinking due to environmental problems. Most notable is the Nile River, over 6,600 km long. Lack of drinking water is a major issue as much of Africa's water is saline ocean or sea water. Various organizations work to improve access to water in Africa where indicators often exceed acceptable pollution levels.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

2. Water in the world
• Water is one of the most widely used
substance in nature. It occurs on the
planet in three states of matter: liquid,
solid and gas. Out of the total surface of
the globe (510 million km2), over two
thirds is covered by water.
3. Africa
• Africa - the second largest
continent on Earth. It takes
30.37 million square
kilometers, or more than
20.3% of the total land area of
the world
4. Hydrology of Africa
• Hydrology of Africa is very diverse. On
the vast expanses of deserts there are
only episodic rivers, while in other
regions huge rivers several thousand
miles long are formed. Most of lakes are
located in the Great Trenches of Africa.
The largest lake is Chad, which dries as a
result of environmental disaster.
5. Rivers of Africa
• There are no permanent rivers in large parts
of Africa. Many rivers flow towards valleys
from which one river flows into the ocean
(Congo, Niger)
The longest river is the Nile River, which is
6671 km long from its source in Lake Victoria
to the mouth in the eastern part of the
Mediterranean Sea.
6. Drinking water in Africa
• In Africa there is not much drinking
water. Most of water comes from the
oceans and the sea (salty), so the main
problem in Africa is lack of drinking
water. Africa suffers from the lack of
water intakes and the available indicators
of pollution often exceed acceptable
norms.
7. Water for Africa
• Because of the dramatic problems with
water in Africa, a number of organizations
try to improve the situation. The most
important of these are:
•Water for Africa
• Africar
• watercan
