I think the most serious ecological problem is flood. Because this Natural Disaster can destroy a lot of house, public built, busyness, companies and industrials. Flood can washes away different houses, even more great and high houses.

People and mankind can protect environment from this Natural Disaster different methods and ways. For instance people produced tall damp for protect from flood. People can clean unnecessary water with aqua pump , which can clean this unnecessary water.

I think in each school teachers must discuss ecological problems with students and learners. Teachers must give solution and ways hep in dangerous moments. If teachers will talk this information, so each students and learners will in friendly.
