A genetically modified organism (GMO) or genetically engineered organism (GEO) is an organism whose genetic material has been altered using genetic engineering techniques. These techniques are generally known as recombinant DNA technology. With recombinant DNA technology, DNA molecules from different sources are combined in vitro into one molecule to create a new gene. This DNA is then transferred into an organism and causes the expression of modified or novel traits.

Genetically modified (GM) foods are foods produced from GMO that have had their DNA altered through genetic engineering. GM foods were first put on the market in the early 1990s. The most common modified foods are derived from plants: soybean, corn, canola cotton seed oil and wheat.

The Causes Of Global Warming - Find Out How Our Daily Habits Have Disastrous Effects For The Planet  

The two main greenhouse gases are the carbon dioxide that contribute to the greenhouse effect to a height of 60% and methane. While methane has only a weak lifetime in the atmosphere, carbon dioxide is still more than a century. Why do we concentrate mainly on reducing the emission of carbon dioxide.

If we fossil fuels, like coal, oil or gas, we burn carbon, thus adding carbon dioxide into the atmosphere: about 20 billion tons per year in the world. The oceans and forests and the plants must be away with about half the excess carbon dioxide. However, this concentration does not stop growing: from 0028% fifty years ago to 0.0365% today.

An additional greenhouse gas is methane (CH4), of which the focus has changed since the industrial revolution. The sources are the rice fields, garbage dumps, cattle farms, and the exploitation of gas and coal. The nitrous oxide (N2O) is another greenhouse gas, from certain industries such as fertilizers.

As we go about our daily lives, we rarely show how our lifestyles impact on the environment. Although we believe May for a few moments that we must be more environmentally conscious, there are only very few of us who really take the time, which is due. The Environmental Science has dramatic breakthrough in determining the causes of global warming. The comprehensive information on global warming requires our vigilance, because many of the causes of global warming are upon us, and that the Global Environmental Outlook will always be worse.

How is that conceivable? The answers are all stare us in the face if we accept to consider.

The first place to find some of the causes of global warming is in our dietary habits . Livestock contributes more to global warming than all other factors. Although it takes on average 24 of gallons of water to a pound of vegetables, 5200 liters of water needed to cover a pound of beef, the tribes of the extreme water resources, as we hear more and more in the news. Like, it takes two calories of fuel to produce a calorie content of soybeans, 54 calories of fuel are needed to create a calorie from beef. Deforestation is another BIGGIE, the animals growth has seven times more than the deforestation caused by all other human activities. Water pollution, heath issues, lost biodiversity, the release of toxins, antibiotics, GMOs, pesticides, sewage, air pollution ... are other factors, livestock, so to the detriment of the environment. The researchers assessed that 2 /5 hectares of land, the food requirement of twenty-two vegetarians, but only two people meet to eat, chicken, eggs or dairy products. Marc Reisner author of Cadillac Desert, sums it up in these words: "The west side of the water crisis and many other environmental problems as well can be explained by one word: Cattle."

Another area to consider in our cities . Every time you drive your car is emitting carbon monoxide. Multiply that pollution with the hundreds of millions of other vehicles and you can clearly see that driving a motor vehicle fuel not add to global warming.

Another way that we contribute to the causes of global warming is by deforestation . The trees in the forests, jungles and rain forests are the lungs of the world. By cutting down a large quantity of trees, the reorganization of these areas will be reduced.

trees need carbon dioxide to live. If large parts of trees are cut, in a place where the balance is gone astray. The remaining trees can not in all of the carbon in the atmosphere. Given this reality, the carbon rises in large quantities in the atmosphere. This is also why deforestation may be one of the main causes of global warming.

Apart from these factors, chemicals such as methane and nitrous oxide are also causes of global warming. These chemicals, while in small quantities are not sufficient to lead to a deterioration of the atmosphere and environment. You may as causes of global warming, if they are used for a range of activities of human needs. These activities include the raising of domestic animals like cows. Other chemical contribution to global warming are artificial fertilizers.

If all these events are taken, you can think independently, they can not cause global warming. However, there are many scientific substantiation, which supports this case. In order to impede the terrible consequences of global warming, you should look at the various causes of global warming and see what steps you can take to circumvent.

The more we appreciate these facts, the sooner we can stop the escalation of global warming. We should not be too long as nature will not wait for us to get our act straight. The effects of global warming are warnings to us, to our way of life.
