?Global warming



Climate could become another not only because of the physical and chemical factors, but also due to biological threats - because of the new artificial organisms, such as plants resistant to insect pests, broken food chain disrupted biological balance - explained "News" environmentalist, Doctor of Biology Irina Ermakova, who represented the International Symposium Russian Academy of Sciences.
Another danger: uncontrolled entry of alien DNA inserts leads to the fact that there are mutated organisms that do not give offspring. Ermakova said that in the future it is possible "global infertility living organisms" and, again, as a consequence, a sharp reduction in biodiversity. With globalization, the use of GMOs will increase its contribution to climate change.
- The climate is formed with the help of animals and plants. Destroy the biosphere - climate change. There will be plants - and therefore no oxygen, insects disappear - and therefore no pollination, reproduction. Everything is connected in a chain - said the biologist.
Global danger of GMOs to the environment is best, according to Ermakova, illustrated by experiments with ice-forming bacteria - Pseudomonas syringae and Erwinia herbicola. Scientists suppress specific gene in these bacteria and placed on the leaves of plants, so that they better tolerate freezing. The experiment was a success, fewer plants were freezing. But the side effect was unpleasant: the bacteria with repressed genes replaced common bacteria its kind. If this process occurs on a global scale, it is possible to predict the environmental disaster will be much less precipitation, scientists warn.
Ermakova colleagues refer to such gloomy forecasts and so bold conclusions cautiously.
- I've known her hypotheses and assumptions on the impact of violations of crystallization on the climate. But I have no evidence, the supply chain, I do not traceable in these conclusions. Violation of the food chain because of GMOs and violation of crystallization, of course, proven in scientific studies. But extrapolate it all on climate change so categorically, I would not. Climate change is associated with multi-system, in which human activities have played an important role - said a senior researcher at the Institute of Developmental Biology.

At the same time, the Rams believes that because of poor knowledge impact of GMOs on the environment, we can make any predictions on the effects of creating fantastic new microorganisms to change the genetic structure of living organisms begin unpredictable occurrence of any protein can be, what will arise spontaneously something microorganisms that will emit toxic substances polluting stronger industry.
