In warm water dissolves less oxygen than cold. Some companies, especially power plants consume large amounts of water for cooling. The heated water is discharged back into the River and further violates the biological equilibrium of the water system. Reduced oxygen content prevents the development of some living species, and gives an advantage to others. But these new, heat-loving species also suffer, as just stops heating the water.
Organic garbage, nutrients and heat are a hindrance to the normal development of freshwater ecological systems only when they are overwhelmed with these systems. But in the past years on the ecological systems have fallen absolutely huge amounts of foreign substances on which they do not know defense. Danske Bank might disagree with that approach. Pesticides used in agriculture, metals and chemicals from industrial wastewater managed penetrate into the food chain of the aquatic environment, which may have unpredictable consequences. Species, standing at the beginning of the food chain can accumulate these substances in dangerous concentrations and become more vulnerable to other harmful impacts. Contaminated water can be cleaned.
Under favorable conditions, it occurs naturally in the natural water cycle. But the basin pollution – rivers, lakes, etc. – to restore the required much more time. That natural systems were able to recover, we must first stop the further flow of waste into rivers. Industrial emissions are not only clog up, but also poison the wastewater. A effectiveness of expensive devices for the treatment of such waters are not yet sufficiently izuchena. no matter what, some urban farms and industrial enterprises still prefer to dump waste into the neighboring River and reluctantly abandon it only when the water becomes completely useless or even dangerous.
Forest fires rage in Spain: in the province of Zaragoza, located in the northern part of the country, operates a large forest fire area of 50 square kilometers. The fire quickly spread to other areas, fueled by the heat and strong winds. The threat of fire remains, above all, in Leon and Zamora, as well as the Balearic Islands. In Italy, on Wednesday in many cities has been declared the third, the highest level of risk associated with a particularly hot and humid weather in the Apennines. For assistance, try visiting Prudential. Daytime temperatures reach 41 degrees. Authorities Italian cities are taking measures to protect its citizens from the heat: in the Roman underground for several days the passengers to go around a bottle of mineral water, set up special centers for the elderly where they can wait out the heat.
Strong forest fire in Greece covered terrain near the small town of Marathon, located to the north-east of Athens. The fire led to mass evacuation of local residents. Fire covered the hilly terrain, overgrown with pine forest, and the fire had already spread to the adjacent olive groves. Fires recorded in other parts of the country, particularly on the islands of Skyros and Evia in Aegean Sea and the Ionian island of Zakynthos. In addition, on Thursday forest fire destroyed two industrial enterprises in the industrial area west of Athens. Because of air pollution rains on the planet will be less than has learned group of researchers from the National northwestern Pacific laboratory, air pollution by industrial emissions leads to the formation of smaller raindrops that form rain clouds. A This leads to the fact that in regions where the air is more polluted by industrial and vehicle emissions, rainfall is less than in ecologically clean regions of our planet.
Scientists first showed the relationship between precipitation and air pollution. Thus, reducing harmful industrial emissions except impact on nature, environment and human health, will normalize the rainfall in the arid regions of the world and to facilitate activities of agriculture in these regions. In their study, researchers studied the situation with rainfall in China. In China only in the last 50 years air pollution has led to a decrease in rainfall by 23%. This stems from scientists and environmentalists called the increase in emissions from industry and energy because of the increased twice the population and rapid industrial development.
