2. What is global problem of the world?

  • The global problems of our time - a set of human problems, the solution of which depends on social progress and the preservation of civilization.

6. Let's look at what consequences us wait?

  • Climate change of the Earth

7. Solution of a problem for a fuel and energy complex

  • Alternative energy sources :
  • 1) solar power engineering;
  • 2) wind-power engineering;
  • 3) alternative water-power engineering;
  • 4) geothermal power ;
  • 5)biofuels.

8. W ind-power engineering S olar power engineering G eothermal power 9.

  • A lternative water-power engineering

B iofuels 10.

  • Problems of an overpopulation of a planet.

11. Way out of crisis

  • Restrictions of birth rate with simultaneous reduction of death rate and to life improvement of quality
  • OR
  • The create alternative kinds of a food. For example - development aquaculture.

12. I think, by means of the offered decisions it will be undoubtedly possible to avoid accident on our planet! 13. Thanks for attention!
