In reality, these products are no friend of the environment.
Plastics are synthetic substances produced by chemical reactions.
Almost all plastics are made from petroleum, save a few experimental resins derived from corn and other organic substances. These properties arise from their molecular structure. Each year, as industry produces more and more nonessential products individually and excessively packaged, we throw away more and more trash. Industry is pushing disposability because it pays. Plastic razors can only be used a few times before disposal, then more must be bought, making the plastic and razor industries rich and happy.
