“The largest sources of toxic substances occur in processes that involve physical or chemical transformation.” (Robertson, 2014)
Robertson discusses how Ford decided to make a new kind of foam in their leather seats of the Mustang. The foam produced was 60% petroleum based and 40% soy bean based. It was shown that producing the soy bean based foam required less energy and emitted less carbon dioxide. I think this is inspiring. More companies should be opting towards more natural ways to produce things that are less harmful to the environment. Big businesses making these changes can considerably help them become more sustainable. The only problem is the cost. If we do start making things with more natural products would the price of those products raise? Would we be willing to pay for them?
“Every piece of material in a garbage can carries with it large quantities of embedded energy and invisible material resources that were part of its life history.” (Robertson 2014).
Everything you have ever used ended up somewhere. Land fills are not exactly the best way to deal with our garbage but it is kind of all we have. What else would we do with all the garbage if we didn’t just stick it in one spot? Dump it in the ocean? Shoot it up into space on a rocket? Clumping it all into one space is basically all we have. We as Americans are the worst with throwing stuff out. Robertson says on average each person in the US throws away about 4.6 pounds of solid waste. That is insane. This is also just personally, this doesn’t take into account the waste that businesses and industries throw out. I was brought up to be conscious about wasting things. I will reuse something until it is completely broken or worn out. I have a hard time wasting food as well. I think more people need to be raised and brought up with this mentality that wasting things is not sustainable.

“Fifty-five percent of paper and cardboard is recycled, making up 31 percent of MSW.” (Robertson, 2014).
MSW stands for municipal solid waste. This waste comes from homes, industries, businesses, and offices. It is collected and treated by municipalities. I was taught to recycle my entire life. My dad taught me at a very young age about recycling. I would have to separate the cans and glass from the paper and cardboard, and then help him bring the bin to the curb. I now practice those same teachings with my roommates at college. I always have to remind my roommate to recycle. She was not raised to recycle and its difficult for her to adjust to it. I always find ways to reuse or recycle things. I feel like this percentage should be higher. 55% of all paper and cardboard is good but its not enough. We should be able to get that number up to 70% or even higher. Recycling paper and cardboard would save a lot of trees in the long run and in turn help our environment.
