How do we handle environmental problems when things corrode or do not decompose?

i have to answer this question for science also if you could help with these two questions:





What properties of substances can you observe, and how do these properties determine the usefulness or hazards of a substance?





Are the elements in the periodic table organized according to their physical and chemical properties, or according to their atomic structure?|||recycle the things that wont be decompose like plastic, dont throw away the things on ground.
