All resources are limited. To ensure that we, and future generations, have what we need to live comfortable lives, we need to husband those resources. Reducing our need, buying reusable items, composting what we can, and recycling when an object is finally worn out are all ways in which this can be done. Not only people, but all of earth's ecosystems will benefit from a change in the way we view consumer goods. Planned obsolescence and excess packaging create a need to use more of our land for trash disposal. Plastic bags and other litter make their way to the ocean where huge 'islands' of our unwanted items pollute the water and kill the wildlife. We can help to reverse this.
