Hmm, I suppose you're right about glass. But, there can and should be a reduction in plastics nonetheless. Glass had been used plenty before plastics came around (e.g., glass milk bottles). And let's say that glass is more expensive, sure. But in terms of environmental costs -- is the manufacturing process less environmentally damaging than that for plastic? I actually don't know the answer to this, would be interesting to know. Of course, companies are looking to increase their profits -- that's why the added cost is unsightly.
Crops are only covered in pesticides and other chemicals (fertilizers included) if they are not grown organically (although SOME agrochemicals may be used in organic farming, if one follows the standards set by the USDA, and I don't agree with all of them). (Add anti-GMO activist to your list of things about me lol.)
Bisphenol A acts as an endocrine-disrupting chemical (EDC) and, in low levels as it occurs in the body, mimics biological hormones (e.g., estrogens) and inappropriately stimulate endocrine receptors on cells. At high levels, it inhibits these receptors. So bisphenol A is like a double-edged sword, a bad one.
Phthalates and brominated flame-retardants (BPDEs) are teratogens and they're found in plastic. BPDEs are really common in electronics, like TVs and cell phones sooo... knowing all this, in addition to what you mentioned, why are we still using SO MUCH plastic? -- at least when it comes to our food containers, toys, etc.
Something you might find interesting if you haven't already seen it is this documentary: Waste = Food (https://www.youtube.com/watch?v=2xhgsKenR5w). It's an interesting concept to deal with all the waste generated from our "stuff." Video quality isn't that great though, sorry.
I also didn't think I'd be using all I've learned throughout my university years haha!
>>6 Sorry Kuro, we're such geeks XD But hey, you should give it a proper read and jump into the discussion, why not ;P And for the record, I think it's my posts that are freakishly long; I always write too much...
