Global warming does not only cause of climate change, but also the interaction with the sexual life in the wild. One of the worrying is the impact of the Maintenance of living creatures that increase in temperature was likely to bear more male than female.

In most animal creep (reptiles), how sex is determined after the egg incubation temperature to incubate fertilized. If the temperature above the average temperature, usually referred to as pivotal temperature, almost certainly will grow into pejantan. This will cause problems if the level of increase in temperature go faster than the natural ability to do adaptation. The number of females will be much smaller than the male.

Threats also faced the same group of fish. The latest research conducted Natalia Ospina-Alvarez and Fransesc Piferrer’s Marine Science Institute in Barcelona, Spain, found that the 6-fish genus of the 20 indicated with positively have sex, which is determined incubation temperature is normal or TSD (temperature-dependent sex determination). Among other things, the genus Menidia and Apistogramma.

Their results showed that the increase of water temperature of 4 degrees Celsius, which is predicted will occur throughout this century will produce the ratio of female and male and proportionate 1 of 3. The ratio is very risky to ensure the viability of fish.

In the human, global temperature increase may not affect the sex ratio. However, the impact will still threaten the continuance of his life in the face of the Earth.
