"Recycle newspapers and save a tree. Collect bottles and calls so they can be reused in the manufacturing of new products."

Protecting our delicate environment seems to be on the agenda of politicians, government leaders, and citizens in many parts of the world to show support for mother nature. The concept of green consumerism has gained impetus more and more over the last decade, and the public feels moved to join in and help. However, three essential keys needed to power this movement include a more informed public, the development of improved technology, and a greater demand for recycled materials.

Let's use paper as an example. The first step is to raise public awareness about the recycling process, to explain the kinds of materials that can be recycled, and provide ways on how to properly dispose of them. Local governments should educate the public on how to properly sort reusable materials from those, like waxed paper, carbon paper, plastic material such as fast food wrappers, that can't be recycled very easily. Then, a system of collecting these sorted materials needs to be established. Give the public information they can grasp, and then you will increase your chances of gaining followers.

Second, technological progress has been made on many fronts, but governmental agencies need to step up their support for companies involved in recycling by providing tax incentives, lowcost loans, or even grants to upgrade equipment and to encourage further research.

The final key is to increase demand for the growing surplus of resources waiting to be recycled. This problem has appeared in various regions of the world where the technology to process the used materials lags far behind the amount being collected for recycling.

Recycling is a crucial link protecting our planet. The three keys mentioned are important ways to achieve this end.
