Civil engineering is one of the most important fields, and without it we can't build our planet [it might be more correct to say build our civilisation/society]. Civil Engineering is a wide discipline that is divided into several subdisciplines. 

Structural engineering is one of them, thats which is interested in analyzing and designing all types of buildings, towers, dams, and bridges as a strength strong structures to withstand under loads, especially during an earthquakes - the worst load - so it will contribute in protection of protect human life,

Transportation engineering thats deals with planning, design, and management of roads, airports, seaports and all of traffic movements to achieve safety - by reducing the probability of accidents -, (increase/enhance) mobility, and to reduce the time of delays.

Environment engineering is the branch thats deals with treatment and recycling of waste and to establish a healthy landfills, in additional to water engineering thats deals with design and analyzing a pipeline systems and open channels to supply a residential area with a sufficient water.

All these branches will build a beautiful world. Civil engineering will rebuild what a wars damage.

Civil Engineering is one of the most important fields as without it we can't build our planet. Civil Engineering is a wide discipline that is divided into several subdisciplines. Structural Engineering is one of them that's interested in analysis and design of all types of buildings such as towers, ([damps] I don't know what you mean to say here), and bridges. These are strong structures to withstand high loads, especially during an earthquake (the worst load) so they will contribute to the protection of human life. Transportation Engineering deals with planning, design, and management of roads, airports, seaports and all other traffic movements. It strives to achieve greater safety by reducing the probability of accidents, increasing mobility, and reducing delays. Environment Engineering is the branch thats deals with treatment and recycling of waste, and the establishment of healthy landfills. In addition there is Water Engineering that deals with design and analysis of pipeline systems and open channels to supply residential areas with sufficient water. All these branches will build a beautiful world. Civil Engineering will rebuild what wars damage.
