We might not be able to see all of the bad things in our environment, but they are for sure there. “Although certain groups are most vulnerable, toxic substances in the environment affect very person, every day and are the responsibility of all of us.” This supports my opinion about the cause because it is saying there are deadly substances in our environment that we are responsible for. We are getting sick and dying because of the bad things we as people are doing to our world. today,this is also stating the things in our air are killing us. All of this dangerous toxic is causing people to get diseases and killing our people we love. If this keeps going on, our families will struggle to have families and this will cause our world and environment to be catastrophic in the future.
