The answer is rainforests. The destruction of rainforests can lead to global warming due to the accumulation of carbon dioxide as a greenhouse gas in the atmosphere. This is because rainforests are major carbon sinks because they sequester carbon dioxide from the atmosphere. One of the major rainforests that are facing the threat of human activities is the Amazon and Congo forests.


The answer is south america’s location atop the Nazca and South American plates of the circum-pacific belt. The circum-pacific belt is also known as the ‘ring of fire’ because there is a subduction zone in the region. The Cocos plate is subducting under the Caribbean Plate. This creates friction between the two plates with occasional release of high amounts of energies when a stuck region gets unstuck abruptly. This region accounts for approximately 90% of the world’s earthquakes.

Discuss the economic and political roles which South Africa or your own country plays at a regional, continental, and internatio
frutty [35]

South Africa has a republican government system, with a mixed market economy, composed of private liberty and a centrally planned economy.

<h3 /><h3>What is a planned economy?</h3>

It corresponds to the economic system where most companies belong to the state, which is responsible for decisions that influence business and the economy, unlike the market economy, which is determined by supply and demand.

Therefore, the centralized economy is an important factor in the country, where the state manages most of the wealth produced, with greater control over the economy.
