Human Population Too much of a Good Thing? Or “What’s Wrong with People?” “I Like People!”

Bio Basics #1 The Earth is finite…. Any questions??

Bio Basic #2 History of Human Population Growth The human population is in exponential growth

Power of Exponential Growth... Yeast example Bacteria example Cancer (mitosis) example

Bio Basic #3 Not only are numbers of humans growing exponentially, but also impact: Pollution Combustion of fossil fuels Destruction of habitat

Bio Basics #4 Female fertility key to population growth Human males always fertile (from puberty on) Human females fertile on key days of cycle

What is result of exponential growth in nature? Answer:  It’s always a CRASH!  Ex: deer on island with out wolves Bacteria in culture

Leaving Biology What are our goals????

Back to BIO… What is the Earth’s carrying capacity ? carrying capacity -
