BIOINSPIRED

RATIONALE
For this project I have chosen to design an indoor compost bin that stores organic waste and uses a Bokashi mix to decompose the waste. For my compost bin I have been inspired by the cocoon. A cocoon is a casing spun by silk by many insects such as moths, butterflies and other holometabolous insect larvae. In my design I was inspired by how something goes in a cocoon and comes out different and this act of metamorphosis is what I have incorporated in my design in how the organic waste goes in and comes out as nutrients for your garden. I have also adapted the form of the cocoon into my design. My compost bin is great for indoor use especially for the kitchen. It’s great for the kitchen because the Bokashi mix has the ability to eliminate any odours that is produced, and also so that you wouldn’t have to go far just to dispose of your organic waste. The compost bin is small enough to not be in the way, but it could also be attached to a wall or on the inside of a cabinet door, so it’s out of the way. And this also mimics how cocoons a located on branches, tree trunks or even in small crevices to keep away from predators. The inside of my design has two chambers. The first is for the waste and the Bokashi mix and the second is for the liquid that is produced from the fermentation, which runs down into the second chamber from the first.
The material I have chosen to use in this design is medium-density polyethylene (MDPE). MDPE is completely recyclable. It also has a lot of shock and drop resistance, so it will be able to withstand a lot of abuse. MDPE also won’t react with the fermentation process so it is ideal for my compost bin. The process I have chosen to make the compost bin is rotomolding, because it will be able to achieve the hollow shape that is required in my design and will also reduce the cost of the manufacturing process.

An Inconvenient Truth


This movie really gets you thinking about the environment and what we are doing to it. The facts stated and the information revealed has shocked many, including myself. Gore used many graphs and statements to show us that global warming does exist, and it is causing many problems for us and the Earth. For example, he had stated in the movie that the top ten hottest years on record have occurred in the past fifteen years. The hottest year was the same year this movie was released, 2005. Also, it was shown that temperature increase is largely dependent on the amount of CO2 released into the atmosphere. Gore also talks about how all of the fossil fuels we are taking for granted, and not only is it hurting the environment that we're using them so much, and if we continue our children may not have the same luxury people have today.

 Besides the fact that our atmosphere and environment are being altered, Gore talks about how weather is affected as well. Gore states that hurricanes have become larger and more violent in recent years, giving Katrina as an example. "Remember that it was only a Category 1 hurricane when it hit Florida" he said. But when it passed over The Gulf of Mexico, the very warm waters caused the hurricane to grow rapidly and become more powerful, so when it hit New Orleans, the result was devastating.

Gore also mentions the Kyoto Protocol. These our guidelines that help us reduce the amount of pollution that is caused, and ultimately help reduce global warming. After Gore stated all of his reasoning for why it should be supported world-wide, I too, would agree with him. 

But is everything that Gore said a bit of a stretch? I'm not saying that what he is saying about global warming isn't true, but I feel he does use a bit of propaganda to make viewers agree with him. But, that doesn't mean you shouldn't listen to him, necessarily, because what he's trying to do is going to help us, not hurt us. 

All in all, An Inconvenient Truth is a very important movie that talks about a major issue, global warming. What's happening to our planet is terrible, and it is the cause of our own ignorance. We are taking advantage of all of the resources that we have been given, and if we keep wasting them, they will one day be gone. I knew about global warming and how what we're doing affects our environment, but I had no idea it was on this large of a scale, or that it was happening so quickly.
