The high price of gold makes mining a very lucrative job finding one or two ounces a day can earn more than working other jobs for a month. ]]> 2017-09-16 16:04:37 UTC https://padlet.com/annaemarks/3zvb2mzpdbl/wish/188159052 annaemarks https://padlet.com/annaemarks/3zvb2mzpdbl/wish/188159090 Mines all over the Amazon area cut down trees to make room for machinery and roads in order to gain as much gold as possible. This deforestation affects the ecosystem in many ways. For example it cause the riverbanks to become more susceptible to erosion. This can  decrease the amount of dissolved oxygen which causes many plants and animals that live in the river to die. This also affects indigenous populations because many depend on fish from the river as their main food source. ]]> 2017-09-16 16:05:17 UTC https://padlet.com/annaemarks/3zvb2mzpdbl/wish/188159090 annaemarks https://padlet.com/annaemarks/3zvb2mzpdbl/wish/188159332 Mercury is used to clump all the gold together. However mercury is very bad for health. Mercury usually becomes runoff after it is used in mines which causes it to be found in people's kidneys. Mercury contamination can lead to many very serious health issues. ]]> 2017-09-16 16:09:08 UTC https://padlet.com/annaemarks/3zvb2mzpdbl/wish/188159332 annaemarks https://padlet.com/annaemarks/3zvb2mzpdbl/wish/188159971 Gold mining helps to develop economies Mining leads to new job opportunities being available and also boost the economy because of how much gold is worth. ]]> 2017-09-16 16:18:51 UTC https://padlet.com/annaemarks/3zvb2mzpdbl/wish/188159971 annaemarks https://padlet.com/annaemarks/3zvb2mzpdbl/wish/188161377 Large-scale mines use heavy machinery and thousands of worker to extract and purify the gold. Small-scale mines use land and river dredging to extract gold. Land dredging is a technique in which a large hole is dug high water pressure is used to blast the soil and expose gold. River dredging is a technique that use pipes to filter out gold.]]> 2017-09-16 16:39:42 UTC https://padlet.com/annaemarks/3zvb2mzpdbl/wish/188161377 annaemarks https://padlet.com/annaemarks/3zvb2mzpdbl/wish/188161634 Gold is mined in the Amazon river basin and countries like Brazil, Peru, and Venezuela.]]> 2017-09-16 16:42:39 UTC https://padlet.com/annaemarks/3zvb2mzpdbl/wish/188161634 annaemarks https://padlet.com/annaemarks/3zvb2mzpdbl/wish/188161716 Gold was discovered in the Amazon region in the 1970's.]]> 2017-09-16 16:44:10 UTC https://padlet.com/annaemarks/3zvb2mzpdbl/wish/188161716 annaemarks https://padlet.com/annaemarks/3zvb2mzpdbl/wish/188161826 Gold is used in jewelry and many other luxury items.
