Environment and sustainability : climate and the 3 Rs

Sustainability means protecting our planet for the future. We must address global warming caused by the greenhouse effect, where gases like $CO_2$ trap heat. Individual actions matter significantly. Remember the 3 Rs: Reduce, Reuse, and Recycle to cut waste. We should also strive to lower our carbon footprint. Every small choice helps preserve natural resources. By changing our habits, we ensure a healthier Earth.

Understanding of basic present tenses (simple and continuous)

Vocabulary regarding nature and simple weather patterns

Global warming is increasing the Earth's average temperature.

Human activity releases greenhouse gases like $CO_2$ and $CH_4$ .

Reduce, Reuse, Recycle to limit waste.

Switching to renewable energy sources.

Meeting our needs without compromising the ability of future generations to meet theirs.

Using solar panels instead of coal power plants to produce energy.

The gradual increase in the overall temperature of the Earth's atmosphere.

The melting of ice caps due to an increase of $1.5^\circ C$ in average temperatures.

The total amount of greenhouse gases (including $CO_2$ and $CH_4$ ) generated by our actions.

Calculating the emissions from a flight versus a train journey.

Reducing household waste to minimize environmental impact.

Step 1: Reduce your consumption by buying products with less plastic packaging.

Step 2: Reuse containers and bags instead of single-use items.

Step 3: Recycle materials like paper, plastic, and glass to turn waste into new resources.

Result: You produce less trash and save natural resources.

Imagine a hierarchy: R-R-R. First, stop buying (Reduce). If you have it, keep using it (Reuse). If it breaks, give it a new life (Recycle).

Think of the Earth as wearing a blanket. Greenhouse gases are the wool that keeps the heat trapped inside. Too much wool makes us overheat!

Confusing 'Weather' and 'Climate'.

Weather is what is happening today ( $20^\circ C$ rain), climate is the long-term trend (e.g., global average rising by $0.1^\circ C$ per decade).

Thinking all trash can be recycled.

Recycling is the last resort. Reducing and Reusing are much more effective at lowering your carbon footprint.
