How do plantations affect biodiversity?
The plantations plant only one type of plant organism (this is also called a monoculture). Other plant organisms are destroyed to make room for the desired plants that produce cash crops.
Animals species diversity is also lowered. Animal and insect organisms that can not make use of the single plant organism either leave the area or die off. Animal and insect organisms that make used of the the pineapples, and bananas are considered to be pest. These organisms are destroyed with pesticides, or restricted with fences and nettings.
The plantations create islands of very low biodiversity.
