I believe that when the human race was first created we started off with Red Blood Cells in our bodies. Over the years as we evolved so did the food we eat, our means of transportation and everything else around us. Not only did we create more waste in the environment but we dirtied our drinking water and air. Which means the food we grow is dirty since they need water to survive.
Because of this over a long stretch of years we began to develop a lot of respiratory illnesses, food born illnesses and illnesses from the bacterias that surrounds us. Our bodies begins to produce inflammation from illnesses and bacterias creating white blood cells to help fight off the bad things to keep us stay alive longer.
Think about it, if everything evolves then its possible that so too did our Blood Cells.
Our bodies has always strive to adapted to its surroundings and so too did everything else around us. Is it possible that our bodies created White Blood Cells to help us adapt to the toxic waste and illnesses we are constantly putting out into the world.
Can this be the reason why, the more White Blood Cells one has, means the stronger ones body is fighting against something bad and the closer one is to dying.
So what if we wanted to cure all sickness, then can we use the body and its cells to point us to the rite direction. The human body might be the answer not only to save us but the plant and animal kingdom also.
Maybe the less white blood cells we have as a whole unit can foretell the healthiness of the environment. Which makes sense because at the moment our white blood counts are higher as a unit and we have more sickness, waste and bacteria in our drinking and air supply than before.
So to know if we are properly cleaning and fixing the earth up, we can judge by our bodies white Blood count level as a whole unit decreasing. This can only be fix in the long term since it is impossible to do it in the short term being as to how unhealthy the earth is at the moment. We have to reset our DNA. Which means we are further away from the day of saving the planet than we are to the day of fixing it.
