The term "sustainability" does not have a clear definition. Generally, it means that people consider future generations in their actions and in their consumption of raw materials. This entails using only as many raw materials as can be regrown or reproduced, which protects the environment, prevents raw material deficits and ensures intergenerational justice.
The ongoing challenge is that many current practices and products are not sustainable. Due to the use of harmful chemicals and environmentally damaging CO2 emissions in manufacturing and the proliferation of plastic and single-use items, these practices have detrimental effects on wildlife and plant life. Added to this is the fact that poorly-paid agricultural workers, often including children, produce cheap products. Also, many people prefer the convenience and cost savings of non-sustainable products or drive short distances as part of their daily routines. Yet there are plenty of alternatives that are not only more sustainable but almost as convenient as their environmentally damaging counterparts.
