Lesson Summary
- Many technologies are available to conserve water as well as to prevent and treat water
pollution. Yet, most undeveloped countries cannot afford the technology they need to
collect, treat and distribute water to their people. - Developing countries may be able to afford water treatment systems, but people still
need incentives to use conservation steps.
Review Questions
- What is the purpose of water treatment and purification?
- How can governments and international organizations help to reduce water pollution?
- Name three things that a person could do to reduce pollution? Use lawn, garden or
