Which economic system has become associated with authoritarian governments and total control of the economy?
capitalism
mercantilism
communism
socialism
barter

Mercantilism and barter are better described as historical economic systems, and in the past the governments and the kings/queens generally kept a closer control of the country, so let's not consider those options.

Now, we have: capitalism, communism, socialism.

Capitalism leaves the capital and the economic decisions in the hands of the private people, not the government. Socialism means a common possession of the means of production, but not by the govrenments, rather by the people, as is often seen as a milder form of communism.

Communism on the other hand is associated with authoritarian governments. Some example were the Soviet Union, and currently, North Korea and Cuba.

Asia is the largest continent on the earth which consists of many countries in it, it is one of the beautiful continents on the earth with a variety of vegetation, Asia consists of some of the world's beautiful beaches and fl-aura and fauna. Unfortunately, due to rapid economic growth with the view to pull out people from poverty this continent is also affected by environmental issues.

The three challenges faced on this Continent are:

Air pollution.Destruction of coral reef.Deforestation.Air pollution is the global issue but in the case of Asia it is worse, local companies set wildfire intentionally to clear the land so they exploit it.The coral reef is the life provider for the aquatic animals and important for the marine environment but due to increasing acidic levels in the ocean killing the coral reef.Deforestation is the process of cutting trees and clearing land for commercial use which also destroys the soil fertility and local vegetation.
