On the 5th of November, I learned that our waste water goes through various cycles to purify. Although, when it is released into natural bodies of water; there is an increase of fresh water within the sea water. The salt water goes through a desalination process.
In class, I found learning about underwater creatures to be the most interesting. I was very fascinated with the deep water creatures. I did not realize that the light hanging off their head was to lure their dinner. I also never realized that they were holes within the ocean floor that contain heat/air.
On the 12th of November, I learned about the population of people. I was interested in the demographic transition model with the four stages. I learned that the majority of people in the world are in the second and third stage of the model. I know that there are no countries within the world that belong to the first stage of the transition model. In class, I also found learning about the population pyramids quite interesting.
Hans Rosling on global population growth
This video was very interesting. It held my attention the whole way through. The information was very well presented. I am not really surprised that the gaps are that big. By using the colored boxes; it makes it more helpful for the average person in the western world to understand that not everyone uses cars and planes for transportation. Many countries still ride on donkeys and have carts to transport their materials from one place to another. I believe that people within the world should strive to make it better. Everyone should be able to buy their own shoes and have their own food to eat.
On the 19th of November, I learned that people today use the Precautionary Principle Approach. This is where the government does not say anything until a product is proven dangerous. I think this is extremely irresponsible. I understand that scientists may need time to understand the productive fully, but the public should not have to worry about if something is dangerous or not. In class, I also learned that quarries contain toxic water. Maybe I should not dive in them anymore…
Endocrine Disruption Expert
This woman sounds very knowledgeable. She and her friend seem to have done a lot of site checking. I think citation checking is not done enough in the world today. People are fine with limited information and are not too bothered about its source. That or they don’t know that not all magazines are reliable. It makes me really nervous that people still create pesticides and toxic chemicals for various reasons when they know deep down that they are not healthy. Something needs to be done before we completely destroy the earth and us along with it.
