This is commonly called littering.
well it does but not that bad as when you make paper because to make paper that causes air pollution and water pollution.
The indicator is litmus paper. :)
They by themselves produce little or no pollution. The pollution comes from the manufacture of the blackboard and book. There may be chemicals in the blackboard and book that can leech out, but it is probably extremely small. I work in a paper mill and we monitor the pollution we produce from the paper making process very closely and we try very hard to minimize that pollution.
You write what causes air pollution (Humans), then write what it does... (Intoxicate out air)
can somebody please answer to this stupid question!! =((
conserves resources and lessens pollution.
Paper mills
pollution
throw plastics,paper,garbage,etc
Some of the sources of pollution where I live include industrial effluents into rivers, noise pollution from industries, and air pollution from paper manufacturing companies, and each negatively affect humans, animals, and plants.
It would save the trees, also, it would lead to less pollution, as paper factories are huge polluters.
say plese
