The Earth Will Undergo Big Changes

Population growth, climate change and environmental devastation are pushing the country toward a potentially fatal and, even more terrible, irreversible biological change, scientists warn.A group of 22 scientists, who presented this warning in the latest issue of the journal "Nature" (Nature), argues that human activity on Earth has caused permanent changes in the biosphere, which is directly related to the mass extinction of many plant and animal species."Human activity leading to the transition that has the potential to turn Earth into previously unknown condition," according to the scientific work of the group by the United States, Europe, Canada and South America.Scientists are convinced that the world is approaching the point of no return after the report that the number of people on Earth increases too quickly, and that global warming exacerbates the situation. Do not help the fact that nearly 40 percent of the habitable area "reserved" for urban development and agriculture.- The ultimate consequences of what we are doing the earth could, at worst, be like an asteroid impact. I do not want to sound like Armageddon to announce, but I think that we must no longer ignore the warning signs - said Antonio Barnoski, professor of biology at UC Berkeley.In 2050. The Earth will live at least 9.3 billion people. By the 2070th , says Barnoski, global warming will lead to the highest temperature in the history of mankind.Because carbon dioxide the oceans are becoming more toxic, while the appearance of the land while dramatically changing due to human activities. All this is causing the extinction of plant and animal species.- We have created a bubble of the human population or economy, which is totally unsustainable. Or will drastically be blown or burst. If the cracks, the consequences for people and for the biodiversity of the planet will be catastrophic - says James Brown, professor of biology at the University of New Mexico.The theory that human activity inevitably leads to the destruction of the Earth is not new, and scientists are at it first began to warn fifty years ago.- This is what the scientists see '60s and '70s (20th century). We are never sure when it will happen. But now we come to that point. I am not optimistic at all. I think it was our duty to proclaim, to say what we see. Are we going to have an impact, it really can not predict, "says Mikael Fortelijus, professor of paleontology from the University of Helsink
