In 1900, the forest cover of the world comprised
A. 2,500 million ha
B. 7,000 million ha
C. 5,500 million ha
D. 1,700 million ha
Solution
In 2015, there were 129 million hectares of loss of forest cover. The total forest cover declined to 5,371 hectares accounting for a total three percent loss.
Complete answer: The forest cover refers to the total land or area covered by trees or forests in square kilometers. The forests are trees covering an area of around 0.5 hectares. And the trees are considered as forest only if they are higher than 5 meters and form a canopy around a threshold of more than 10 percent. The agricultural land is not considered a forest area.
Option A is 2,500 million hectares. It is an incorrect option as the total forest cover was around 4,128 million ha to 5,500 million ha.
Option B is 7,000 million ha. This is also incorrect as the total forest cover area in 1900 was less than 5,500 million ha.
Option C is 5,500 million ha. It is correct as the total forest cover in 1900 was around 4,128 million ha to 5,500 million ha.
Option D is 1,700 million ha. This is not the right answer as it is nowhere between 4,128 million ha to 5,500 million ha.
So, option C is correct
Additional information: Forest cover can be characterized as one of the major characteristic categories of total terrestrial land cover. It was noticed that the world lost three percent of its forest cover in the year 1990. This loss was equivalent to the area covered by South Africa.
Note: Forests are large ecosystems that play a major role in balancing the biospheres on the Earth. Thus, important measures should be taken to improve the global forest increase rate. Although the average loss rate has halved now from the 1990s, care should be taken and deforestation should be avoided.
