CO2 + H2O + energy -> CH2O + O2
CH2O + O2 -> CO2 + H2O + energy
Given aundant resources, most populations show spectacular growth
If growth rate per individual is constant, population can grow exponentially.
Eventually, 'carying capacity' is reached, and then birth rate = death rate
Increased vegitation productivity -> more O2 -> more forest fires -> less O2
1) life has altered the enviroment at global scale throughout Earth history
2) Life tends to stabalize the enviroment as global scale by reducing
variability of physical and chemical factors
3) These alterations increase probability of persistance of life
