erly can you gi#e one@

/o#erty .ir

'hat?s right +ut why do you thin po#erty "ecomes threat to "iodi#ersity@

.ir people are force to use and depend to our natural resources "ecause they ha#e no other source of their daily needs

9ery good hat else@

;'he students will raise their hands<

Eristina what?s your answer@

.ir mining

'hat?s correct Cow does mining affects "iodi#ersity@
