This is commonly called littering.
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.
can somebody please answer to this stupid question!! =((
conserves resources and lessens pollution.
Paper mills
To write a paper on the causes and effects of air pollution, first, research different sources to understand the various factors contributing to air pollution and its impacts. Organize your paper by outlining the key causes and categorizing them as human activities, natural sources, or industrial processes, then detail the effects of air pollution on human health, environment, and climate. Conclude by offering potential solutions to mitigate air pollution and its harmful effects.
pollution
throw plastics,paper,garbage,etc
It would save the trees, also, it would lead to less pollution, as paper factories are huge polluters.
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.
say plese
Yes. It saves trees, it saves energy(as making new paper from old paper use less energy than making it from scratch), and it also reduce the volume of waste going to landfills.
