Effect: The war changed economic, political, governmental, and social relations between Britain, France, and Spain; their colonies and colonists; and the American Indians that inhabited the territories they claimed. France and Britain both suffered financially because of the war, with significant long-term consequences.
Causes: In the early 1750s, French expansion into the Ohio River valley repeatedly brought France into armed conflict with the British colonies. In 1756–the first official year of fighting in the Seven Years War–the British suffered a series of defeats against the French and their broad network of Native American alliances.
Answer:
Americans had played an active role in the economy and politics of cuba.
Explanation:
Before the 1959 United States and Cuba they have a good relationship. The rise of General Fulgencio Batista in the 1930s to the de facto leadership and presidency during two legislatures (1940-44 and 1952-59) produced a period of close cooperation between the governments of Cuba and the United States. The second term as President of Batista was initiated by a planned military coup in Florida, and US President Harry Truman soon recognized Batista's return to power with military and economic aid. When Fidel Castro came to power in 1959, relations between the two countries quickly devolved into bitter arguments, political grandstanding and the occasional international crisis.
Answer:
Explanation:
Stratospheric ozone is important because it acts as the blockade to harmful UV radiation directly from the Earth. If there were no stratospheric ozone then the life on the Earth was not possible because direct exposure to UV rays cause Skin cancer and many more health problems to humans and animals and plants. Thus, Stratospheric ozone is very important because it absorbs the penetration of harmful UV radiation as well as other harmful radiations. Whereas, the ground level Ozone becomes a harmful gas because it has adverse effect on the Human lungs. Old aged people, children, outdoor working people etc. mostly get effected in their breathing and taking smooth air from the environment.
The role of Ozone depletion in the stratosphere by the CFCs is very crucial because 1 molecule of CFC can destroy 100,000 molecules of Ozone by a simple chemical reaction in the presence of UV. More the CFCs in the environment and in the Stratosphere cause more Ozone depletion. And, this may lead to penetration of harmful UV rays into the Earth surface.
When the connection between CFCs and ozone depletion was well understood, many of the people (scientists, business persons, public, politicians) started to adopt the tecchnology which do not produce CFCs. Till few years ago, our refrigerator, AC and other instruments used to produce enough CFCs but, nowadays this has been significantly reduced. Similarly, the burning of plastics and other CFCs producing fuels has been banned or reduced. All the concerned authorities made strong rules to reduce CFCs in the environment and in the Atmosphere. And, this led to decrease in the depletion of Ozone on the stratosphere.
Answer:
There are many causes of soil degradation in Ethiopia, but the main ones are deforestation, overgrazing, and poor farming practices. Deforestation leads to loss of topsoil, which is essential for plant growth, and also exposes the underlying rocks to erosion by wind and water. Overgrazing can also lead to loss of topsoil, as well as compaction of the soil, which makes it harder for plants to grow. Poor farming practices, such as not rotating crops or using too much pesticide, can also lead to soil degradation.
