Transportation was a very interesting and a very complicated topic about climate change when I was researching the topic, especially when it come's to the battery and how the ingredients inside the batteries how so interconnected, the biggest challenges when it come's to transportation in particular was the battery weight and how larger thing's require much much much larger batteries and how these materials are getting sourced, and the complications with large companies getting these materials from middle men companies that have mine's in other countries and the challenges with surrounding cobalt in particular, because these people are being exploited, insanely underpaid, like really really underpaid, and it's not like we can just stop using these materials because they are required in the solutions, but the other challenge is that because many organizations are making this issue very clear to the companies which is a great thing, the possible unintended consequence is that the companies will start looking to source these materials in other countries were the labor laws are much stronger and less opportunity for exploitation for business or for their reputation, and what happens is all these people who were digging the materials for these large middle men who sold it to even larger companies, the people digging these materials are going to out of work and their already in very very very bad levels of poverty and even if the job they have at the moment is inhumane they will have not many other options of income and their could be large number's of deaths from starvation and other caused deaths due to no income. That is the most difficult and largest problem that I found while doing transportation research, all other aspects like battery technology and thing's like that is more "first world country issues" but the mineral issue is really complex and their are many good possible solution proposed which is a good thing.
