Yes, canals are still used. There are several major ship canals around the world, such as the Suez Canal (Red Sea to Mediterranean Sea) and Panama Canal (Pacific to Atlantic Oceans).There are also a goodly number of smaller canals and "navigations" (rivers modified to be navigable) around, particularly in Holland, France and Britain; but these are generally used now by pleasure-craft although they were built as commercial waterways.Britain has a large, complex network of 18C canals that largely fell into disuse during the 19C when the new railways took away most of their trade, but which have been restored in the last few decades for pleasure use. The Rivers Severn, Avon and Thames are all linked by such canals; and the City of Birmingham has an impressive mileage of canals around it, originally serving the wealth of local industries.
The environmental problems of transporting crude oil across the sea is that if it were to be spilt some how then it would be in the sea for a very long time ( 1-2 years) this will affect the creatures of the water for exmple the fishes In fact spills from tankers have been a regular occurrence and the effects can last for decades. In the case of the Exxon Valdez spill into Prince William Sound in Alaska, for example, there is still residue present and it is still having negative effects on the environment.

Robots are used everywhere. They can dive deep in the sea where humans cannot go or on dangerous missions that endanger human lives
Windmills help people in many ways. In olden times they used it to grind wheat for bread. Now we mostly use it to harness the power of wind energy and converting that into electricity. In netherlands, they use windmills to pump water away thereby leaving land for urbanization. Even today, most of the netherlands is below sea level.
They are still being studied by scholars.

Salt comes from two sources. One is sea salt and the other is from salt mines. The primary source of salt a thousand years ago was the salt lagoons of the northern Yucatán peninsula. The lagoon was dam up connecting the sea and to make salt beds. Nature does the work through evaporation and then they just scooped up the salt. This method is still used today around the world for sea salt.
