Many are under the misconception that recycling is about the planet. The truth is recycling is about you and me. Yes it does and can save trees and natural resources but the reason that is important is because we the people need those resources to live well.
All landfills will eventually fail and leak leachate into ground and surface water. Plastics are not inert. State-of-the-art plastic (HDPE) landfill liners (1/10 inch or 100 mils thick) and plastic pipes allow chemicals and gases to pass through their membranes, become brittle, swell, and breakdown -Source www.zerowasteamerica.org/Landfills.htm
Old and new landfills are typically located next to large bodies of water (i.e., rivers, lakes, bays, etc), making leakage detection and remediation (clean-up) extremely difficult. This is due to the incursion of surface water in both instances. Federal and state governments have allowed landfill operators to locate landfills next to water bodies under the misguided principle: Detection by monitoring wells can also be very difficult at lined landfills. Lined landfills leak in very narrow plumes, whereas old, unlined landfills will produce wide plumes of leachate. -Source www.zerowasteamerica.org/Landfills.htm
Waste management places considerable strain on the environment. Waste disposal sites, whether active or closed, can result in serious pollution of groundwater due to leachate -Source naturegrid.org.uk
I could go on and on but here's the kicker...we receive our food from the ground. We receive our water from river, lakes and streams. So yes, it is good for the planet but it is vital for us now and in the future. If the ground has hazardous material than how nutritious can the food be that we will eventually eat?
Recycling give us a better chance of a healthier life.
