Q:how do humans use plastic negatively?
Plastic surgery, it can be 100s of years and that will be what's left long after the humans decay. certain packaging that can use alternative packaging could help reduce the use of plastic. Medically plastic is great because it is easily sterilized and also helps sterile fields because a lot of plastic things are single use then thrown away. Chest tubing saves lives and they are plastic.

Q:When did plastics bags become a problem?
why do you think they're a problem? They're convenient, light weight, clean, and strong. 100 of them take up less space in a landfill than a milk carton/jug. They are NOT the problem in the oceans. The problem there is plastic fishnets that have been lost by fishing boats. The nets ARE a problem, since they float and continue to catch and trap anything that goes into them. Testing has found that reusuable environmentally friendly cloth bags, used as replacements for plastic bags, soon build up high levels of bacteria as they are reused, so they need to be washed frequently which requires lots of water and detergent. In addition, at a cost of up to $5 each, buying and storing enough of them at home to handle a single trip to the grocery store can get prohibitively expensive for poor families who may use up to 20 plastic bags each trip to market to haul their groceries home. As for a year that plastic bags became a problem....it was the year immediately after plastic was touted as the salvation of the trees chopped down to create paper bags for grocery stores. Never let an environmentalist tell you what to switch to. It'll never be good enough. Just like all the environmental lawsuits now showing up in courts to stop clean energy projects (dams, windmills, solar arrays, geothermal, etc). All they want is for everyone to die and leave the planet to the frickin animals, because surely everyone can see that humans are a blight on the planet and should never have evolved.
Q:Paint for both metal and plastic?
Most paints are good for both metal and plastic. - but you have to prepare the surfaces - sanding the surfaces is pretty good. Paint stores sell a de-glosser that will prepare them to be painted. --- You don't want to use spray paint - but walmart sells a spray paint especially made for slick surfaces (plastic and metal) -- maybe a paint store would sell paint in a can that is also made for slick surfaces (metal and plastic that has not been sanded) edit: only a light sanding is needed to prepare the surface.
Q:what plastic can i recycle?
problematic problem. research over google. that will may help!
Q:How is type 1 plastic (PET) recycled?
recycled plastic is chopped into very small pieces and melted together. Then a new plastic is extruded.It can be made into a fine fiber that can be woven into fabrics. There are t-shirts, socks, hats as well as carpets made from soda bottles. The cost benefit ratio depends on getting people to buy recycled products. When collection of the bottles is handy, people will do it. The deposit on soda bottles has helped in some places to get people to return the bottles. More advertising of green goods would help, as well as lower cost for the green products.
Q:What are all the types of plastic?
complex step. do a search from a search engine. that may help!
Q:how lubricate a plastic zipper?
Zipper Lubricant
Q:Is plastic harmful? blablabal?
I don't trust plastic. When heated I know it can leach out carcinogenic chemicals. It's full of them. I don't know if just putting a bottle cap in your mouth would do it but there are no benefits from doing that. Seems like the rise of cancer coincides with the rise of plastic materials.I wonder if your parents never drink out of a plastic bottle. My suggestion is don't heat food in plastic or pour hot liquids into a plastic container to drink.
Q:Plastic?????/?
People always are on plastic's case about not breaking down in the environment but I want to make 2 points: 1] most plastics could be (and some are) recycled and/or recovered and converted into some other useful material. 2] If plastic is dumped somewhere it will stay there, at least it doesn't break down and release potentially harmful materials into the environment. So yes, It doesn't go away, but it isn't going to hurt anything either. Things that are far worse in terms of pollution when dumped are nicad/mercury cells, old car batteries, mercury switches, wood scraps treated with CCA, waste solvents, electronic trash such as old curcuit boards with lead solder, old car engine oil (usually contaminated with arsenic, anitmony, tin, lead, ect from bearings, old paint which often contains lead, chromium, cadmuim compounds etc. When this stuff breaks down these materials can spread through the soil/water table and contaminate a much larger area than the original dump site. It is very expensive and time consuming to clean up these messes after the fact! I If, after a 100 years, we figure out what to do with all that plastic we threw out, we can dig it up and it will still be there right where we put it!
