Summary

In modern world we have to face different problems like food, energy and economic crisis. I think it is a question of attitude, whether exists lack of food or finances to afford it. Attitude is the worst problem, because attitude is something we can alter very slowly, sometimes never. Many people in developing countries do not just have enough money to buy food and necessities. Knowledge, abilities and technology should be distributed, so that they could manage better. To alleviate energy crisis alternative fuel and energy resources should be used-also a question of attitude and lifestyle.
