vacuum distillation
Traditionally, the best way of taking salt out of water has been through vacuum distillation. The salt water is enclosed at a low pressure to reduce its boiling point, making it easier to vaporize to separate the salt from the water.
the salt water is heated or the water is allowed to evaporate,the water vapour is collected rather than being lostthe water.vapour is condensed to form pure water/fresh water, salt is left behind and can be used for other purposes.

Answer:
There are greater opportunities for trade in the pacific rim than in the steppes.
Explanation:
Trade is something that has been used by humankind for thousands of years. The reason is simple - it is the basis of any economic type, be it primitive, command, market, etc... Basically, through trade, the individuals, groups, countries, regions, get the goods they need in exchange for the goods they have to offer and are needed on the other side.
Not all places on Earth provide the same opportunities for trade though, and in most cases the reason for it is geography. The Pacific Rim, for example, is a huge region and there are countries on all levels of development. It is a region where infrastructure doesn't have much influence because trade goes through water, and even though it is a huge distance in question from one side to another, trade is very easy. On the other hand, we have the steppes. These areas are sparsely populated, are usually low on resources, the climate is harsh, which in turn makes the countries dominated by them are less developed, and that in turn means infrastructure in bad condition or fully lacking in most of the territory. Such conditions result in bad conditions for trade as the opportunities are much lower than in other regions.
