The correct answer is option 2, that is, recycle and reuse materials.
Sustainable living refers to a lifestyle, which tries to minimize the society's or individual's application of the Earth's natural and personal resources. The environmental sustainability does not signify living in the absence of luxuries but rather being aware of the consumption of resources and minimizing the unnecessary waste.
Recycling and reusing the products are two basic, yet highly efficient approaches, to minimize the filling of wastes in the landfills. Recycling and reusing substances assist the community, economy, and the environment as well.
Recycling inhibits the emission of various greenhouse gases and water pollutants, supplies valuable raw materials to the industry, and saves energy. It not only boosts the economy but also benefits the surroundings.
