Model Answer
(i) Water: We use fresh water from rivers and ponds for drinking and cleaning but dump garbage into them, causing pollution. If this continues, after several years we will have no clean water left for our use.
(ii) Fuel: We use large amounts of wood from trees as fuel and for construction. As more trees are cut, it affects the climate, leading to extreme weather conditions like floods, extreme cold or heat.

Explanation
- Each sub-question gets roughly 1 mark, so 1–2 crisp sentences each is sufficient.
- Examiners look for: (i) the problem (pollution/dumping garbage) and the consequence (no clean water); (ii) the cause (cutting trees for fuel) and the consequence (climate change/extreme weather). Include both for full marks.
- Use the exact textbook language where possible — it matches the marking scheme closely.
