All the problems stated here are associated with the disposal of solid waste.
<u>Explanation:</u>
Solid waste, depending on the material, undergoes degrading actions like rusting and corrosion.
These actions break down the material through electrolytic reactions to produce various chemicals that percolate in the ground and contaminate the groundwater.
More the solid waste, more are the efforts required to recycle it. This discourages recycling efforts that need to be taken in regard to the solid waste.
Solid waste is also problematic because finding locations for landfills is not an easy task.
Solid waste contaminates the resources and reduces available renewable resources. Moreover, solid waste also pollutes the soil through various degenerative reactions.
