This is apart of threshold number 6 ,collective learning, because people have to share ideas with each other to make tools.

A positive of this is that it is a good on-the-go fuel, but it is finite and expensive.]]> 2018-05-04 13:33:33 UTC https://padlet.com/vazquyad000/31j854jiazc4/wish/258023870 sommeale000 https://padlet.com/vazquyad000/31j854jiazc4/wish/258024634 Humans used fire to cook,light dark places, and warmth.  This is also apart of threshold six because they had to learn to use fire, which would mean it was collective learning.]]> 2018-05-04 13:34:59 UTC https://padlet.com/vazquyad000/31j854jiazc4/wish/258024634 tilsodom000 https://padlet.com/vazquyad000/31j854jiazc4/wish/258024965 2018-05-04 13:35:42 UTC https://padlet.com/vazquyad000/31j854jiazc4/wish/258024965 sommeale000 https://padlet.com/vazquyad000/31j854jiazc4/wish/258025569 Humans domesticated animals for many reasons such as carrying cargo loads, transportation, and agriculture.  Unlike the two before this is apart of threshold 7, agriculture, because domesticated animals were mainly used for agriculture. ]]> 2018-05-04 13:37:01 UTC https://padlet.com/vazquyad000/31j854jiazc4/wish/258025569 sommeale000 https://padlet.com/vazquyad000/31j854jiazc4/wish/258151702 Humans used Coal and steam for steam engines. This is apart of threshold 7 and 8 because it was used in 7 and continues on through 8. A negative for this use of energy would be using fossil fuels which means coal will eventually run out. A positive would be it is relied on a lot by the USA and the UK. Another negative would be it's hard to mine and it pollutes the air. ]]> 2018-05-04 19:34:21 UTC https://padlet.com/vazquyad000/31j854jiazc4/wish/258151702 vazquyad000 https://padlet.com/vazquyad000/31j854jiazc4/wish/258500317 Nuclear power that humans learned to control was from nuclear reactions that released nuclear power that was then converted to electric power. This is considered threshold 8, because it involves a new energy resource like number 9. A positive of this type of energy is that it is cheap and easily controllable. A negative is that it also creates hazardous waste.]]> 2018-05-07 13:00:37 UTC https://padlet.com/vazquyad000/31j854jiazc4/wish/258500317 vazquyad000 https://padlet.com/vazquyad000/31j854jiazc4/wish/258504774 Humans had to use just the right amount of power to make energy his takes place in threshold 8 because it is a new goldilocks condition in a way for threshold 8. A positive effect of the sustainable power is that it provides threats to breakdown.]]> 2018-05-07 13:10:27 UTC https://padlet.com/vazquyad000/31j854jiazc4/wish/258504774
