💧 Water Pollution

💦 Why Water Is Important

Water helps us to:

• Drink and stay alive 💧

• Cook, clean, and wash 🍲🧼

• Grow crops and feed animals 🌱🐄

Botswana does not have a lot of water, so we must take good care of the little we have.

🛑 How Water Can Be Polluted

Pollution happens when dirty or harmful things enter water.

❌ Things that pollute water:

• Washing clothes and bodies in rivers

• Throwing rubbish into dams and streams

• Letting dirty water from toilets, farms, and factories run into rivers

• Using too many chemicals on crops

• Animal waste (like cow dung) entering water

♻️ How to Get Rid of Dirty Water

Safe ways to dispose dirty water:

• ✅ Use non-chemical water to water plants

• ✅ Pour dirty water into a soak pit

• ✅ Pump chemical water into a sewage dam

• ✅ Recycle dirty water so it can be used again

🚫 How to Prevent Water Pollution

✔️ Use toilets instead of bushes
✔️ Do not wash in rivers
✔️ Do not throw chemicals or rubbish in water
✔️ Find safe ways to reuse or throw away dirty water
✔️ Plant trees to protect soil and reduce erosion

😷 Water-Borne Diseases

Water that is polluted can make us sick. These are called water-borne diseases.

⚠️ Examples:

• Cholera – causes vomiting and diarrhoea

• Bilharzia – comes from water with snails, causes blood in urine and weakness

• Typhoid & Dysentery – make the stomach hurt and cause fever

💡 Malaria is not water-borne, but mosquitoes breed in water and spread it.
