Environmental Degradation of Plastics - Phantom Plastics

The reason is simple – degradation occurs mainly at the surface and the smaller the particles become, the more surface is exposed. The same is true for other materials. For example, leaves degrade more rapidly than trees or sticks even though both are made from the same polymer – lignin and cellulose. Plastics Degradation – Perspective & Context

Agriculture & Soil Degradation — The Conscious Challenge

Jun 11, 2019·The degradation of our soils, due to human activities, today, can harm our well-being. It causes the extinction of species and accentuates climate change. It also contributes to the displacement of populations and the multiplication of conflicts. A major part of soil depletion is due to the lands over-use and the products that we pour on it.
