Paul Andersen explains how populations eventually reach a carrying capacity in logistic growth. He begins with a brief discussion of population size ( N ), growth rate ( r ) and exponential growth. He then explains how density dependent limiting factors eventually decrease the growth rate until a population reaches a carrying capacity ( K ). A mathematical simulation of this process is included along with a brief discussion of r and K selected species.

Aquaponics combines two growing methods, aquaculture and hydroponics, to create a self-contained, well-balanced ecosystem. Fish are fed and raised in a tank and as gravity pulls the wastewater through a hydroponic garden, bacteria feed on the waste, breaking it down into essential nutrients for the plants to grow. The system then returns the cleaned water back to the fish reservoir so the process can begin again.

In this episode, Charles Collins shares his backyard aquaponic and hydroponic gardens where he's able to grow tilapia, leafy greens, peppers, herbs and so much more, all in the suburban desert. Together we grow!

What might seem as waste to Africa’s many herbivores is gold to the Dung Beetle who needs animals dung for its species survival. Not only do these dung beetles gather and roll as much dung as possible but they will even resort to high jacking another’s ball, which it has spent many hours perfecting. But not without a fight.

The Food and Agriculture Organisation FAO, is calling for the transformation of Africa’s agri-food system to make healthy diets more affordable. A new report shows Africans are missing out on the nutritiuos foods such as fruits, vegetables and animal proteins due to high costs. The report also shows the number of undernourished in the continent has risen to over two hundred and fifty million people.
