Reduce, Reuse, Recycle: Waste Management

• Proper waste management is achieved through the "three Rs": reduce, reuse, and recycle.
• The "three Rs" help conserve resources and reduce waste.
• To reduce means creating less waste, like using a cloth lunch bag instead of a disposable plastic bag.
• To reuse means using the same object several times, like using empty glass jars to store items.
• To recycle means reclaiming materials to create new products.
• Commonly recycled materials are glass, plastic, paper, and metals.
• Separating waste into different categories makes it easier to recycle materials in recycling plants.

Recycling Paper

• Recycling paper involves mixing paper with water and chemicals to produce pulp.
• The pulp is filtered to remove glue or ink.
• The paper pulp is dried into thin sheets, resulting in recycled paper of lower quality.
• Recycled paper can be used to make cardboards, tissues, and writing paper.
• The more paper recycled, the fewer trees are cut down, and the less garbage is disposed of.

Recycling Metals

• Metal mining consumes significant energy and causes habitat destruction.
• Recycling metals helps reduce pollution from mines, power stations, and disposal sites.
• Recycled metals include aluminum, lead, and iron.
• Recycling metals involves collecting and sorting metal objects, shredding, processing, and melting them to make new metal objects.

Recycling Plastic

• Plastics are mostly nonbiodegradable, so recycling limits harmful accumulation in land and water.
• Plastic recycling involves sorting, chipping/grinding, and melting plastic wastes into pellets for new items.

Recycling Glass

• Discarded glass is transported to treatment plants, sorted by color, and washed to remove impurities.
• The glass is crushed, melted, and molded into new products.
• Glass recycling uses less energy than manufacturing new glass from raw materials like sand, lime, and soda.

Conservation Programs

• Conservation programs help reduce negative impacts on the environment.
• These occur at local, national, and international levels.
• They maintain genetic diversity by protecting species and preserving/restoring habitats.
• These programs also regulate logging, mining, fishing, and hunting.
• The World Wildlife Fund (WWF) works in over 100 countries to preserve biodiversity.
• Multinational agreements like CITES protect endangered species from trade threats.

Habitat Preservation

• Habitat destruction is a major threat to biodiversity.
• Destruction can occur with the removal of keystone species.
• Keystone species play a crucial role in an ecosystem.
• Preserving keystone species is vital for habitat preservation; live corals are an example.
• Coral conservation initiatives reduce threats to coral reefs and increase public awareness.
• Tropical rain forests are important for human survival and regulate atmospheric carbon dioxide.
• The destruction of rain forests increases the risk of greenhouse effect and global warming.
