what is sustainable devlopment?
keep our ecosyst healthy
meeting present needs w.o compromising future gen’s ability to do the same
keep our ecosyst healty: have enough functional intergrity to continually provide resource
solve chemicals added to plastics
alt: ___, ___ ___, ____ ___
use BPA-free products
avoid can: most of em have BPA resin
avoid heat + plastic
alt: glass, stainless steel, biodegradable palstic
earth is ____ system ->
1 SYSTEM: 1 ecosphere w/ many ecosyst within. do system thinking.
tell me more abt health effects on marine food chain
bcs plastic absorbs toxic subst,
marine animal eat it think it’s food => biocaccumulate up the food chain
human health: chem & particle toxicity
causes highest release of ___ & ___ into ___ compared to chilling in fridge or store @ room temp
within 3 min of heating, ______
microwave: plastic, into micro & nanoplastic
release 4.2M micro & 2.1 B nano into 1 cm2 square
e.g of biodegradable plastic
microwave— use biodegradable plastic
truly green plastic TM: converts cannabis waste -> biodegradable polymer
by law, cannabis waste must be treated tb unfit for human consumption
=> extra cost to enviro
solution to microfibre @ production lvl
__ ___ ___ for durability & recyclability
companies to __ ___ __
__ fabrics using __ farming tech
propose legisla:
European Comission want fashion companies to produce sustainably
set min standards
collect textile waste
nat /regenerative
solution to microfibre @ consumer lvl
buy high-quality clothing- shed less
add nanoball to washing machine to collect microfibres ; use filter
or even waterless washing machine
sustainable dvlopmen is not a _______ after ___ goals are achieved
[—] [—]
a healthy society would give_______
luxury after econ
if u damage ecosyst-> cant provide basic human needs -> less chance to do econ dvlopmnt and social justice
