The conclusion is from the scientists who studied the increase in the acreage of maize as the main agricultural plant to produce bioethanol. It turns out that the number of plants at a certain the territory is directly related to the number living in this area of insect species. Accordingly, the insects had settled on the ground, where grows a small number of plant species, less natural enemies. Its research biologists conducted on corn fields in 23 U.S. states. Surveyed scientists were aphids, which cause great harm to crops, and ladybugs that eat aphids.
It turned out that the larger the area planted only corn, the less ladybugs can control aphid populations. Thus, the mass migration to the use of biofuels will lead to sharp increase in the populations of insect pests and the damage multiplied by pests has increased markedly. The outgoing year 2008 was a very ‘rich’ in natural calamities and disasters Counting down their last days of 2008 is very sad statistics as the year in which the frequent natural disasters caused serious damage and great human losses. Thus, victims of natural disasters in 2008 were 238 000 people. The results showed that more than half of deaths from natural disasters in 2008 – is a victim of Tropical Cyclone Nargis, which struck the southern coast of Myanmar (formerly Burma) on May 3.
Material damage from rampant disaster is estimated at $ 4 billion. The second accident, which led to a huge number of victims in 2008 – a devastating earthquake in Sichuan Province, the victims of this natural disasters have 87 000 449 people. A lot of troubles and hurricanes have brought ‘Ike’ and ‘Gustav’, faced by the United States and the Caribbean in September. In total, according to un estimates, more than 230 thousand people became victims of natural disasters in the first half of 2008, and the economic losses from natural disasters during this period reached 35 billion dollars.
