The exploitation of marine resources beyond any reasonable criterion of sustainability is an increasingly serious and widespread problem. To identify overfishing relative to the maximum limit of fish that can be caught without threatening the presence of a particular species, we use the term "overfishing": a concept we risk hearing about more and more often and especially in our dear Mediterranean Sea where over 90 fish stocks are subject to overfishing.
While we wait for the big hitech innovations, we can change the city starting from the local administration; for example, did you know that only by facilitating the spread of so-called “telepasses” will traffic be significantly improved and tons of harmful emissions saved? According to a United Nations report, the percentage of people living in urban areas will continue to increase in the coming decades.
Naples until today has been famous for the problems related to garbage, from this moment on it will be famous for the discovery of the local CNR, a bacterium capable of eating waste and producing energy. The bacterium is called "thermotoga neapolitan" and will transform waste from problem to resource. The discovery was made by Dr. Agata Gambacorta's team who has been conducting field research since 2008.
The environmental alarm for the island of Giglio is about to go off. The Costa Concordia, the giant of the sea that was shipwrecked on the night of 13 January, risks contaminating the surrounding environment despite the precautions taken by the technicians. The marvelous Tuscan marine park could suffer irreparable damage if the works were not successful.
Wastewater poured into rivers and seas, mercury-polluted fish and contaminated agriculture. These are just some of the consequences that heavy metals can cause in water. In April 1998, in Spain, heavy metals contained in the water contaminated a crack in the mining dam of the Coto de Donana nature reserve, the result was the genesis of 5 million meters of fanco contaminated by lead, copper, zinc, sulfur and cadmium.
The tanks may contain gasoline, propane, or any other form of conventional fuel, but the energy tanks located north of Berlin contain wind-generated energy and more: a hybrid power plant sponsored by four large companies is being tested. The plant wants to test a new hybrid technology that will exploit wind, hydrogen and biogas.
In theory, algae could represent the new frontier of biofuels. The new technique was developed by the University of Sheffield and aims to produce biofuels from plant substances; biofuels are considered an important alternative to fossil fuels but the production costs and difficulties encountered by experts are enormous, today algae could represent the ideal solution for the efficient production of biofuels.
GreenPeace periodically publishes a guide to the greenest electronics manufacturers. By the end of 2011, GreenPeace has drawn up a ranking of the 15 most eco-virtuous electronic brands. The podium of the ranking of the greenest electronics manufacturers is occupied by HP, which is particularly skilled in enforcing sustainability standards throughout the manufacturing chain of its products.
Remember the oil spill of the Gulf of Mexico? It happened almost two years ago, when two oil rigs exploded releasing rivers of hydrocarbons into the Gulf of Mexico. The major damage was caused by the failure of a British oil rig, Deepwater. Who caused the Gulf oil spill?
The effect known by the name "heat island" concerns urban areas, in fact it seems that the temperature in the city is higher than in the surrounding regions that are not yet urbanized. The difference in temperature can be significant, homes and offices consume a lot of electricity, thus increasing greenhouse gas emissions and therefore the temperature.
There are many alternative energy sources and they give us the opportunity to generate clean energy without damaging the environment; however, current technology does not allow us to efficiently exploit everything we have, so clean energy is not enough. Among renewable sources, hydrogen is rapidly entering the scene.
As the world prepares to welcome the first GPS watch, researchers at the Georgia Institute of Technology (Georgia Tech) are developing the model for a nuclear clock that would get its pinpoint accuracy from the core of a single thorium ion. There are many ecological watches powered by the sun on the market, the nuclear clock is priceless.
What am I wearing today? I look in the closet, maybe I put that jacket on so I recharge my smartphone too. It is not a dream, it will soon become reality with Power Felt, a fabric capable of generating energy to power small portable devices. It will soon be possible to recharge our portable devices with what we wear.
As the world's first biodegradable plastics spread, a team of British researchers prepares to create the first plastic produced from eggshell. Eggshells are currently being disposed of in landfills, with such developments could gain commercial value and start a new one. life in the form of iPhone covers, mice and many other plastic accessories.
There is a lot of talk about green economy, sustainable development, but what are the conditions of the Italian forests? Fortunately, the data are not alarming, on the contrary, in recent years there has been an increase in green areas, the summary? Twelve billion trees cover a third of the Italian territory.
One out of two dangerous products is made in china, the other of European origin. These are the results of careful analysis conducted with the Rapex rapid information system which examines dangerous products other than food. Toys and clothing are the most dangerous products. The EU is using a control system called Rapex, thanks to which dangerous products can be identified and promptly removed from the market.
Common chemicals, found in household products, could be the cause of medical ailments like cancer, reduced fertility and obesity. To put us on guard is the European Environment Agency (EEA) with a study published last Thursday.The European Environment Agency has not issued any ban, it has only warned that there is a need to intensify checks to analyze best five classes of chemicals, including phthalates.
Do you want summer? Better to choose the Italian beaches for the 2012 holidays! The European Environment Agency rejects Italy for the quality of the air but fully promotes it when it opens up to beaches! The 2012 report is clear, the 7,000 km of coast of the boot is more than suitable for bathing. With its coasts, Italy contributes to 35 of the bathing coasts of the entire European continent.
In Italy conventional power plants fail. The economic crisis spares no one, not even oil. Of course, it will not be the crisis that will break down fossil fuels but the decadent market itself: oil is touching ever higher prices and alternative energies can boast excellent yields and state incentives.
It is the first time that in a collection of important laws such as the Development Decree approved by the government, the green economy is explicitly mentioned. This is enough to make it an interesting starting point in the reflection on the interventions necessary to relaunch the Italian economy in a sustainable way, although of course its practical implementation remains to be verified.
Photographer Nicolas Wickström has decided to capture animal abuse in a "new light", this time the center of the lens will not be vivisected monkeys or malnourished dogs, the subject is man and the photos are of high emotional impact. BY NICOLASC There are countless studies that prove the sensitivity of animals.
