Answer:
When the first World Book was published in 1917, there were only two independent countries in Africa: Abyssinia (now Ethiopia) and Liberia. Together, they made up less than 5 percent of the land area of the continent. The rest of Africa was divided into colonies controlled by the European nations of Belgium, France, Germany, Italy, Portugal, Spain, and the United Kingdom.
Organized groups in some African colonies began demanding self-government early in the 1900’s. But a mass independence movement did not take shape until after World War II (1939-1945).
Some countries gained their independence relatively peacefully. In 1951, Libya, which was an Italian colony in 1917, became the first country in Africa to gain independence. In 1956, France granted Morocco and Tunisia independence. That same year, the United Kingdom granted Sudan independence as well. Other countries saw much bloodshed before their independence was granted. In Algeria, a bloody revolt raged against the French from 1954 until the country won independence in 1962. In Kenya, members of a movement called Mau Mau revolted against British control in the 1950’s. The revolt failed, but it contributed to Kenya’s eventual decolonization in 1963.
Explanation: Today, Africa is divided into 54 independent countries. Several European countries still control a few small islands: the Madeira Islands (controlled by Portugal), Mayotte and Réunion (France), and Saint Helena (United Kingdom).
Some scientists think that Earth goes through natural cycles of warming and cooling. The difference in the current cycle of the Earth's temperature change is that the Earth is heating quicker than in prior natural cycles.
The warming of Earth is not only because of biological reasons like volcanic eruptions, forest fires, and such but also because of the human actions which add up to it. The smoke from factories, the use of aircon, refrigerator burning of fossil fuels, etc. They all donate to the planet's more rapid warming making it more difficult for human societies and the natural world to adapt.
