Lesson notes preview

Read the core explanations from Global and Local Environmental Solutions before testing yourself from memory.

• Picture this: every minute, an area of forest the size of 20 football pitches disappears forever. Meanwhile, the average UK household throws away 1.1 tonnes of rubbish each year. These aren't just statistics — they're symptoms of a planet under pressure.
• Human activities are pushing ecosystems to breaking point. But here's the good news: governments and communities worldwide are fighting back with solutions that work. Some tackle the problem globally, others start in your local area. Both matter.
• Understanding these solutions isn't just about passing your exam — it's about recognising how science shapes the policies that will define your future. Let's explore how the world is responding to environmental crisis.
• Forests are Earth's lungs — they absorb CO₂ and release oxygen through photosynthesis. When we cut them down, we lose this natural carbon storage and release stored carbon back into the atmosphere. It's a double hit for climate change.
• The permanent removal of forests and trees from land, typically for agriculture or development. Reduces biodiversity and increases atmospheric CO₂ levels.
• Governments are tackling deforestation through several key strategies. **Trap**: Many students think deforestation only affects climate — actually, it destroys habitats and reduces biodiversity too.
• Protected Areas: Countries like Costa Rica have set aside 25% of their land as national parks. No logging, no farming — just protected ecosystems. Brazil has created massive reserves in the Amazon rainforest.
• Reforestation Programs: China plants 6.6 million hectares of new forest each year. That's like covering the entire Republic of Ireland with trees annually. These new forests absorb CO₂ as they grow.
• Economic Incentives: Norway pays developing countries to keep their forests standing. Indonesia received $1 billion for reducing deforestation rates. It's cheaper to pay for conservation than deal with climate change consequences.
• This approach catches many students off-guard in exams. Can you identify which strategy would be most effective?
