Many archaeologists study about garbage to know about ancient society.The university in Arizona started Garbage project in 1973.This students traveled landfill and researched about it.They had to be careful in landfill and used equipment.Students thought that garbage is disappear quickly,but actually,garbage disappear slowly. |
The best way to dispose of this garbage is recycling.There are other poisonous metal or chemical such as hazardous metal like batteries and moter oil.If the batteries or moter oil go in to landfill,the hazardous meterial come out and move the landfill.To use less batteries,people used the rechargeable batteries.So people have to do recycling,but reycling also hard because it needed time equipment,and treatment.But in 1982,Toronto successed in recycling and reduced 25% of garbage.![]() |
