Silent Spring


((https://www.google.com/search?q=smaug&espv=2&source))

"The most alarming of all man's assaults upon the environment is the contamination of air, earth, rivers, and sea with dangerous and even lethal materials."

Carson spends a lot of time focusing on how man is destroying the environment which is a very important subject. In this particular passage she digs into what are in her opinion the most harmful ways man destroys the environment. It is important to understand that everything in life occurs in a cycle. Whether it is the biotic pyramid or the water cycle the earth is constantly working in a cycle continuously reusing resources. When things as dangerous as lethal materials are dumped into the ocean they go through the water cycle and and end up in the air, water, and land. The same goes for air pollution. Once the air is polluted and evaporates whatever was in that air can end up on the land or in the water.


"This pollution is for the most part irrecoverable; the chain of evil it initiates not only in the world that must support life but in living tissues is for the most part irreversible."

This quote was very scary and eye opening. In this day and age it is easy to become numb to hearing about things like air pollution and cars destroying the environment but people need to learn to take action now because the mistakes we are making now are IRREVERSIBLE. Once we abuse the environment to a certain point it will not be possible to go back and fix it. This is why it is important that we go green as soon as possible in order to save the planet before it is too late. 



''...control must be geared to realities, not to mythical situations, and that the methods employed must be such that they do not destroy us along with the insects."

(https://www.google.com/search?q=sustainability&espv=2&biw=1280&bih=589&source)


This quote stresses the importance of being careful with how much we attempt to control the environment and in which ways we do it. Natural pesticides are suitable options in order to control the insect population opposed to man made pesticides that can be lethal. If not done properly we can eliminate people on accident while attempting to eliminate insects. This is why it is always important to seek natural alternatives when working with population control. 



"Nature has introduced great variety into the landscape, but man has displayed a passion for simplifying it."

For some reason people constantly feel that they can be doing better. It is because of this that people continuously attempt to find ways to simplify things. Although iPhones and other forms of technological increase are great examples of this none are more historic than nature. Man has been trying to manipulate the planet since day one in attempt to make life easier. Although we must sometimes manipulate the environment out of necessity we must draw a fine line between surviving and just taking advantage of the planet.

Shiva Biodiversity

(https://www.google.com/search?q=biotic+pyramid&espv=2&biw=1280&bih=633&tbm=isch&tbo=u&source)

Due to the fact that it is so simple the biotic pyramid doesn't seem like it gives us much information but in reality it is what life is based on. As we learned in class it is not a hard concept to grasp. The biotic pyramid is the food chain and it shows in order how energy is transferred. This easy concept can be applied to anything involving life and it is important that we respect it and don't use technology to alter the steps in this pyramid. We need nature to survive and manipulating it can be catastrophic. 


"Throughout the twentieth century it was considered that substitutes could be found for resources supplied by biodiversity: renewable sources of energy -wood and animal energy- could be replaced by fossil fuel; manure for growing food could be replaced by the products of fertilizer factories; and medicines could be made from synthetic molecules. But fossil fuels have given us climate change; agrichemicals have threatened species, undermined soil fertility and human health; and synthetic drugs have had fatal side- effects."

There is no way to beat nature. We must play by the environments rules because we need it to survive. Although manipulating the natural environment may sometimes turn out in short term success things will always fail in the long run. As Shiva has shown us, everything that we humans have done to cheat the environment is beginning to backfire. Things like fossil fuels seemed to work for many decades, but we have recently began to see the dreadful side effects such as pollution and climate change. We must not lose sight of the biotic pyramid and learn to follow its steps exactly without manipulating the environment. 

                                         (https://www.google.com/search?q=fossil+fuels+negative+effects&espv=2&biw=1280&bih=589&source)


"The extinction of a species means not just the loss of that particular species, but also a threat to the other species that are supported by it through ecological process."

                                                            (https://www.google.com/search?q=species+extinction&espv=2&biw=1280&bih=589&source)

Once again we go back to the importance of the biotic pyramid. If you alter even one of the stages of it they will all be negatively affected. The vegetation require the microbes, the animals require the vegetation, and the humans require the animals. All of these are required for life to exist and if any of these are removed the rest would go extinct. 

"Biodiversity is not just a conservation issue, it is an issue affecting economic survival."

                                                (https://www.google.com/search?q=economy+and+nature&espv=2&biw=1280&bih=589&source)

Most of the time when ecological issues are brought up there is a large amount of people who are not concerned with it but only care about money. The thing about biodiversity is it involves both so everyone is affected. Everything we have today comes from nature one way or another and if we neglect and mistreat the environment parts of it can go extinct that we require to make things. This will remove items from circulation which would for sure hurt the economy.

A Tale of Two Farms


Diamond opens this reading in an extremely unique way that I found very interesting. He began by comparing the similarities of both farms as if they were both fully operational farms which made it easy to compare them. He then goes on to to tell us that Gardar farm was abandoned over 500 years ago. Had he have opened up by telling us this it would have been harder to compare the two and made this reading much more difficult.


                                                           (https://www.google.com/search?q=gardar+farm&espv=2&biw=1280&bih=589&source)



“…even the richest, technologically most advanced societies today face growing environmental and economic problems that should not be underestimated."

                                                  (https://www.google.com/search?q=success+to+failure&espv=2&biw=1280&bih=633&source)

This is the moral of the story! Nothing is ever unstoppable and Diamond uses some great examples to drive this home. He shows us a modern business that is on top and shows no sign of slowing down and compares it to one that was in the exact same place and went on to fail. Having a failed business to compare it to made it much much easier to understand how serious this really is. 

"...many of those mysterious abandonments were at least partly triggered by ecological problems: people inadvertently destroying the environmental resources on which their societies depended."

Sound familiar? They say we learn history because it repeats itself and this is a prime example. Many times we humans have taken advantage of our environment and the results have almost always been catastrophic. A great example would be after the civil war when American settlers began killing Buffalo in the thousands and almost forcing them to go extinct. As we've discussed many times we cannot live without our environment so this is another important lesson to take care of what we are given. Had the environment been preserved and properly taken care of it is highly probable that Gardar farm would have thrived for years to come. With how people are taking advantage of the environment today (car pollution, massive expansion, growing population, etc...) it would not be a surprise to me if Huls farm went down the same path that Gardar farm did.

"Those past collapses tended to follow somewhat similar courses constituting variations on a theme. Population growth forced people to adopt intensified means of agricultural production..."

Similar to the video we viewed in class we see a pattern where a growing population has forced farmers to abandon the "old fashioned way" of farming and switch to unconventional mass production forms of farming which are not only not as nutritious but usually take more from the environment. The biggest lesson from this reading is to use Gardar farm as an example. Do not take advantage of your environment because the environment always wins!
