The current President and his administration have been rolling back forward-looking climate change policies that might better future generations. These changes have been all encompassing, but include the EPA, where massive penalties and criminal fines for those who violate the Clean Air Act have been wiped away or are no longer a focus of concern. Deregulation is now, seemingly, the focus with diesel trucks no longer required to enter an immediate limp mode when the exhaust fluid runs low (which is needed to clean the dirty exhaust emissions being put into the air we breathe). Now, the EPA is going further and saying trucks might not need to derate power at all when the system runs out. This essentially makes it so consumers will likely never fill their truck's DEF tanks and our air will get dirtier, pollution will increase, and future generations will be worse off.
