I have learned some about food contaminated recycling which I sadly was not always aware of. Also, some items we think or assume are recyclable (some plastic bottles, containers, food containers, etc.) which are not can be frustrating. When items are marked with the recycle symbol on the bottom with a number in the middle of the 3 arrows, that makes you think that item would be able to be recycled. It can be confusing, and also further confusion as to what your local area does and does not recycle.
Also now that other counties such as China who used to take on 2/3 of the world's recycling waste is not doing so, I feel it is up to our own individual government to find a way to make it happen internally. We create our own trash; we have to be responsible to dispose of it correctly, including recycle and reusing it. The world is changing, and we have to do better to change responsibly with it.
