Imagine a world where everything was made from metal, wood and wool. The transportation of liquids and foodstuffs would be extremely costly forcing prices to rise exponentially. Not only that, the protection of certain surfaces, the construction of goods in the home, the waterproof clothes that we wear, all of these need to have plastic in their make up at some point.
We need plastics and they are now completely dominant in our lives. We cannot keep on using wood as trees are precious. Metals are a finite resource. This is why companies like https://www.rackzone.ie/shelving/plastic-shelving are looking to use Plastic Shelving as an option for your storage and warehouse needs.
One other thing that should always be remembered is that the majority of plastic is recyclable. These can be used to make a plethora of new items. Wool cannot do that. Wood can be recycled but it usually takes the form of a weaker inferior type like chipboard or MDF. Cotton clothes are the victim of fast fashion, tonnes of it end up in landfill every year. We need to look at our use of plastics for certain, but at least we have a chance to reuse it so that we do not need to add anymore as waste into the environment.
