Once abandoned, the plants of the rainforest will find it difficult to grow back in that area. [37] Forest fragmentation also opens the path for illegal hunting. Species have a hard time finding a new place to settle in these fragments causing ecological collapse. This leads to extinction of many animals in the rainforest.
Ethiopia, the third largest country in Africa by population, has been hit by famine many times because of shortages of rain and depletion of natural resources. Deforestation has lowered the chance of getting rain, which is already low, and increased erosion. Berkeley Bayisa, an Ethiopian farmer, offers one example of why deforestation occurs.
Deforestation and forest area net change are not the same: the latter is the sum of all forest losses (deforestation) and all forest gains (forest expansion) in a given period. Net change, therefore, can be positive or negative, depending on whether gains exceed losses, or vice versa.
An ecological cascade effect is a series of secondary extinctions that are triggered by the primary extinction of a key species in an ecosystem.Secondary extinctions are likely to occur when the threatened species are: dependent on a few specific food sources, mutualistic (dependent on the key species in some way), or forced to coexist with an invasive species that is introduced to the ecosystem.
A pioneer tree species, one that is able to quickly regenerate after a disturbance, may be able to reassert its role in the forest while a climax tree species may not. [10] Forest impacts can be divided into two phases: short-term physical disturbance caused directly by the pest, and long-term changes in ecosystem functions in response to the ...
A post with over 275,000 views on X claims that President Joe Biden “wandered” into the Amazon rainforest immediately after giving a speech. Verdict: Misleading He walked down a path he was ...
Deadliest animals as of 2016 [1] This is a list of the deadliest animals to humans worldwide, measured by the number of humans killed per year. Different lists have varying criteria and definitions, so lists from different sources disagree and can be contentious.
