In the reading there was two major aspects in creating sustainability, ecosystem and
agroecosystem. A ecosystem is a relationship between living organisms and the environment
interacting as a system. While a agroecosystem functions as an agricultural system with all its
inputs and outputs. A agroecosystem can also be known as a ecosystem that has been
modified by humans to boost agriculture growth.
When we look at both a ecosystem and agroecosystem they have similarities and
differences. Both systems use some sort of energy flow, the ecosystem will use the source
of the sun as energy, but agroecosystem uses other sources other than sunlight. Nutrient
cycling in a ecosystem is pretty easy the system just naturally reuses the nutrients from
the crops that are already planted. The agroecosystem due to the loss of nutrients in the
soil from erosion it now relies on heavy synthetic and top coats to help replace what the
soil has lost. While stability only seems to possible at the moment through agroecosystem
it must maintain the in and outputs of humans.
The challenge in creating a sustainable agroecosystem is trying to make it as
natural as possible, while maintaing the same amount of output. When you are able to
produce more output using human made ecosystem. Why would anyone want to farm
the natal way? Farmers are forced to use machinery and chemicals to maintain crops.
Using the fertilizers and chemicals cause quit a bit of harm to the soil which is needed to
grow the crops. The pest asides used do kill the pest that will kill crops, but it also kills
their natural born enemies. Not only do fertilizers and chemicals help the plants and food
grow, but it can also cause harm to the humans and animals when it is leaked into the
natural water supply. On top of harmful chemicals and killing of all pest, farmers are
required to use machinery to help turn soil which can cause solid...
