39. Summary All kinds of waste is dangerous to the environment The realistic exposition and exploration of environmental effects is crucuial Plastics are not better, but not worse compared to other frequently used materials The plastic waste is managable  Planing  Recycling  Incineration  Deposition (this is not the right solution) Waste management is possible only organically Protecting the environment is the responsibility for all the humanity 39
