The Three Rs

The three r's

Recycle, Reduce and Reuse

Start

Class objective: Discuss and understand the importance of recycling

What are the three r's?

Reduce

The idea that we should buy goods only when we need them and avoid buying unnecessary ones

+ info

Reuse

The idea behind it, is that we should use the products we buy as much we can before throwing them away.

+ info

The idea behind it, is that we should encourage the act of recycling products by putting what is left in the proper recycling stream bin to be recycled.

5 Benefits of Recycling

+ info

1. Conserving natural resources

The world's natural resources are finite, and some are in very short supply.

2. Protecting ecosystems and wildlife

Recycling prevents damage being done to the natural world: fewer forests cut down, rivers diverted, wild animals harmed or displaced, and less pollution of water, soil and air.

3. Saves Energy

Making products from recycled materials requires less energy than making them from new raw materials. Sometimes it's a huge difference in energy.

5. Creates jobs

4. Cuts climate-changing carbon emissions

Roughly 30,000 of the new jobs would be in recycling directly, with roughly 20,000 more in supply chains and the wider economy.

Because recycling means you need to use less energy on sourcing and processing new raw materials, it produces lower carbon emissions.

Why is Recycling important?

Class Objective: understand the concept and forms of pollution

WHAT IS POLLUTION?

Pollution is the introduction of contaminants into the natural environment that cause adverse change.

TYPES OF POLLUTANTS

Pollution can take the form of:

• Chemical substances or
• Energy, such as noise, heat or light.

Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants.

Forms Of Pollution

• Air pollution
• Light pollution
• Littering
• Noise pollution
• Plastic pollution
• Soil contamination
• Radioactive contamination,
• Thermal pollution,
• Visual pollution,
• Water pollution.

• Air pollution: the release of chemicals and particulates into the atmosphere.

• Electromagnetic pollution: the overabundance of electromagnetic radiation in their non-ionizing form, like radio waves

• Light pollution: includes light trespass, over-illumination and astronomical interference.

• Littering: the criminal throwing of inappropriate man-made objects, unremoved, onto public and private properties.

• Noise pollution: which encompasses roadway noise, aircraft noise, industrial noise as well as high-intensity sonar.

• Plastic pollution: involves the accumulation of plastic products and microplastics in the environment.

• Soil contamination: occurs when chemicals are released by spill or underground leakage.

• Thermal pollution: is a temperature change in natural water bodies caused by human influence.

• Visual pollution: which can refer to the presence of oversized elements on the visual field in a given area.

• Water pollution: by the discharge of wastewater from commercial and industrial waste (intentionally or through spills) into surface waters;

Classwork 1 In your own words, answer the following questions: 1. What things or activities can you do to REDUCE the use of plastics in our daily lives ? 2. Mention 5 ways or examples on how we can REUSE plastics? 3. Mention 5 ways in which we can RECYCLE materials such as glass, paper, and plastics? 4. How can you contribute to reduce pollution? 5. Mention why is so important to take care of the environment?
