1. Farming. It may seem that Russia with its cold winters is not the best place for farming, but it is not correct. Firstly, most of Russia's European regions have quite mild winters and warm summers, and in some regions (like Crimea or Krasnodar) you can easily grow subtropical cultures. Secondly, in Russia you can buy large and cheap land plots ideal for farming. Thirdly, many territories have not been affected by human activities and allow to grow truly organic products. Finally, farmers in Russia enjoy state support and reduced taxes.
2. Teaching. Over 50 million of Russians are below 30. Most of them are eager to learn to broaden their horizons and get new career opportunities. Language courses from a native speaker are always in demand, especially courses in English, German, Spanish, Chinese and Arab. Language courses do not require much investments, and you can always support your teaching business by offering translation services.
