Just now my sister was doing Liberal Sudies homework and it's about air polution.
Just getting scared these days,like what if we breathe air and those are polluted,we can easily sneeze or get sick.
And thinking about Hong Kong's junkyard,they said that 4 or more years it's gonna be full and no space left.
What about the ices in the glacier,what if they melt? Think about it......
You could die if there's lots of things that are polluted.
Since Hong Kong's junkyard is full,people have these thoughts like use a rocket to launch into space or put it in the volcano.
Think about it...
Launching it into space takes a lot of time,you need materials to build a rocket woth lots of money,and dumping in the volcano can take a while. Recycling could help but it's not really helpful,just a little.
We use too much gas and stuff,it's gonna make Earth even hotter since hot is stronger than cold.

I read that worms can eat plastic, as if its natural waste.

Speaking of plastic, I do not know how efficient is, but my grandma worked in a hospital (she retired ~2006 or so) and she said that various stuff like syringes, perfusion bottles and so on were made of glass and if they needed a cap it was a rubber of some sort (still has a bunch of those things at home) and said that after used, the parts that couldn't be reused (like the needle, which is made of aluminium if I remember correctly) were thrown away and the bottles and syringes were sent to sterilization and reused. Now they all are made of plastic and thrown away after usage, whenether it's either better or a cheaper alternative to the glass, I believe that going back to it (or using it more generally) can be better. True may be a lil' bit more costy than simply using a plastic one, but reusing them would prevent recycling or other fabrication processes (minus sterilization) plus they wouldn't need to be bought again.

Also we can use glass for our simply bottles. I've heard from several people that water kept in a glass bottle is kept better than a in a plastic one. One can buy a glass bottle of water for a certain price and then return the bottle to the shop and buy another, in that way, when returning the bottle, when you get a new one you only pay it's content. (Here is how buying beer works. You buy it for a price. If you return the bottle the next one is cheaper for not needing to pay for a "new bottle", but only get it's content. If you do not return then you pay the full price.)
