 Tropical rainforests are being destroyed and badly degraded at an unsustainable rate. Some 
scientists estimate that in the early 1990s tropical forests were being destroyed at a rate of approximately 
28 hectares a minute, or about 14 million hectares each year - an area about the size of the state of 
Wisconsin. This figure marked a decrease since the 1980s, when approximately 16 million hectares were 
destroyed each year, largely due to a reported decline of deforestation in the Amazon River Basin in the 
early 1990s. However, satellite images indicate that rates may have rebounded in the late 1990s as 
burning in the Amazon increased again. Over the past three decades alone, about 5 million square 
kilometers - or 20 percent of the world’s tropical forests - have been cleared. During this time, 
deforestation in tropical Asia reached almost 30 percent. High rates of deforestation are inevitably 
followed by alarming rates of plant and animal extinction because many rainforest species cannot survive 
outside their pristine rainforest habitat. Some scientists estimate that dozens of rainforest species are 
becoming extinct every day.
 Causes of deforestation vary from location to location, but certain patterns tend to be consistent 
across all forests. Logging companies in search of valuable rainforest hardwoods, or, less often, oil 
companies in search of petroleum, are often the first to enter a remote area of rainforest. Some logged 
forests, if left alone, can regenerate in a few decades. But typically, they are not left alone - the roads built 
by logging companies often provide access for landless farmers to enter a new area, as well as a means to 
transport agricultural crops to market. For every 1 kilometer of new roads built through a forested area, 4 
to 24 square kilometers are deforested and colonized.
 Once the loggers leave the land, a typical cycle of destruction ensues. When the landless farmers 
arrive, they clear the land for planting. Poor rainforest soils produce a low crop yield, especially after a 
couple of years. At that point, the farmers often sell their lands to cattle ranchers or large plantation 
owners. After nutrients have been exhausted and soils compacted by cattle, lands are then abandoned and 
often laid to waste. Rainforest does not readily regenerate on these lands without human intervention. 
Meanwhile, the colonist farmers and cattle ranchers move to a new piece of land made accessible by 
logging roads, where the cycle of deforestation begins again.
__________ 1. According to paragraph 1, the rate of rainforest destruction was greater in the 1980s than 
in the early 1990s.

__________ 3. Deforestation in tropical Asia reached 20% during the past three decades.
__________ 4. The extinction of plants and animals is due to excessive deforestation.
__________ 5. The most common cause of deforestation in different regions is the search for oil.
__________ 6. Some logged forests can recover in a few decades if they are left alone.
__________ 7. Tropical forests do not easily regenerate on abandoned and wasted lands without human 
intervention.
__________ 8. The passage mainly discuss causes and effects of rainforest destruction.
