Question

What once covered 14% of the earth’s land area, but by 1991 over half had been destroyed?

Answer 1

i think that it is glaciers which have been melting due to global warming

Answer 2

Answer:

1. Rain forests formerly covered 14% of the Earth's land surface; presently, they only cover 6%, and experts believe that the last remaining rain forests will be eaten in less than 40 years, and most likely by the end of the century, if current deforestation rates continue.
2. Deforestation will threaten or obliterate over half of the world's plant, animal, insect, and microbe species within the next quarter-century.
3. Every second, one and a half acres of rain forest are destroyed, and researchers estimate that deforestation is responsible for the extinction of 137 plant, animal, and insect species per day, equating to 50,000 species per year.
