Every action has an equal and opposite reaction...

Our world is a fragile one; because of this, we have to be very careful when we dispose of the garbage that we accumulate.  There is no excuse for the negligence of littering.  This may have colossal repercussions on our environment, and thus may affect us in a negative way.  Pollution has the capacity to destroy many ecosystems that hold important organisms.  These creatures may be essential in the food chains of the environment to which they belong.  If these organisms die, others may be affected inside of this bionetwork.  In the end, these events will reach us.  This is not inevitable; we can incite our society into being more cautious about their decisions about the environment.  This way, we will be able to mitigate the likelihood of these occurrences and stimulate the improvement of our environment.
