Population Growth in a Yeast Colony

Carbon dioxide production is used to infer population growth in a colony of baker's yeast. We can monitor the population as it moves through the four phases of growth, ending with carrying capacity, in which the available nutrients are inadequate to support further expansion of the population.

Like yeast man will not stop breeding until the environment stops him we are just not any smarter than yeast. It is pure natural fact nature has programed us to saturate our environment until something culls us . What ever it is war,pesstulance, food depletion , environmental poision. Or all the negatives may peak close to the same time but no chance man will intervine impossible man never learns these lessons.

@obedied

You realize if you took every human in the world and had them stand side by side they would fill up only a fraction of Rhode island right? We're far from overpopulation.

@bnel890 I watch what is happening locally. Streams even with all the rules and regulations about storm water control are getting more and more polluted . Farming all the new GMO's having plant toxins inserted into their DNA so insects cannot eat them but we do. Exotic medications being discharged into rivers and streams at parts per trillion are causing cancers and changing the sex of fish populations putting them in decline. The list goes on and on. None of this is being addressed.

my computer laged in the lag period of the clip..

[gone2dogz]

The so-called "lag" and "acceleration" phases are both periods of exponential growth. Labelling your third phase as "exponential" is misleading. You could re-label your third phase as something like "really fast growth", or discard the first two phase labels entirely.

Fun to watch, anyway.
