Why population growth is a public health concern?

In most contemporary models of the earth there is only a finite amount of resources so as populations rise the amount or resources available to each individual shrinks. Studies show us that this informations is not really accurate since less than 2% of the entire human population control use and access to 90% of all material resources on the planet. This unequal distribution makes it nearly impossible to know how many people the earths resources are actual capable of maintaining since most people are denied free access to resources due to laws and regulations that are created my people who already have access to resources and thus  can deny access to other. In many ways the concepts of ownership and profit prevent fair distribution of resources. 

The average resting heart rate (hrrest) for a 34 year old is 73 beats per minute2. 34 year old males average heart rates of 71 bpm while females average slightly higher at 76 bpm2. the normal resting heart rate range for all adults and children 10 and over is between 60 and 100 beats per minute3. 90% of 34 year olds resting pulses fall within the range of 54 to 92 bpm. in general, an adult's resting heart rate will be lower for those in better athletic condition.
