Conservation of biodiversity in the current period is one of the important issues internationally. Major changes occurred in the last 50 years ecosystems require the need to reassess the situation with stringent ecological diversity both at the species level associations and bodies. Very important is to save and preserve plant and animal species are endangered. Risk factors to these are represented by forest destruction, true genetic deposits, introduction of alien species (so-called biological pollution). Our traditional response to the problem of plant and animal species extinction was setting up parks and natural reserves. Unfortunately this path may be of limited value because of the very risk factors for biodiversity. If we can not stabilize population and climate when there is no ecosystem on Earth that we can save him.
