The best organic health? The paper decimating forests. Harmful GMOs for the environment? Not that easy…

1) Paper decimating the forest

FALSE The paper industry uses for its production, as the by-products of the forest (falling sawmills, branches, tops ...). In France, furnishings and packaging absorb more than half of sawn hardwood, and the building sector is 60% wood timber uses. In tropical countries, forests are first victims of Agriculture (80% of the causes of deforestation) livestock and population pressure. Each year, an area the size of Spain disappears for example in the Brazilian Amazon. The Southeast Asia and Africa are also overexploited areas.

2) The bottled water is greener

FALSE bottled water is no better for health (some even have a recommended water mineral content for current consumption). It also leads to significant environmental consequences: increased consumption of raw materials and energy to manufacture bottles, packaging, bottling, and transportation to get them in stores. Finally, plastic bottles generate 135 000 tonnes of waste per year in France.

3) The hole in the ozone layer is due to greenhouse gas

FALSE In reality, it is not a "hole", but a decrease in the concentration of ozone in the atmosphere, especially above the polar regions. This thinning is due to chlorofluorocarbons (CFC), widely used in the manufacture of refrigerators, air conditioners, or solvents. In contrast, CFCs are not greenhouse gases. So these are two distinct phenomena

Renewable energy will replace oil

True and false. Facing oil shortages and global warming, we will need to develop non-emitting energy sources of greenhouse gases. At the same time, we will have to almost double the production of energy in the world in the coming years 50. Knowing that today 80% of our energy comes from oil, gas and coal, renewable energy (wind, solar ...) will make a valuable contribution but necessarily incomplete due to their low productivity. To provide massive amounts of electricity required, it is unclear how do without nuclear power does not emit greenhouse gases. With new types of reactors, the uranium reserves would secure for centuries the world's electricity needs. Following is a question of political choice ...

Oil is solely responsible for the greenhouse effect

FALSE The Kyoto Protocol has designated the gases responsible for the greenhouse gases: water vapor, carbon dioxide or CO2, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and hexafluoride sulfur. If the CO2 is responsible for over 50% of the increase of the total greenhouse gas, methane is important because its heat retention capacity is 21 times. A large amount of methane in the atmosphere comes from livestock, rice fields and landfills.

GMOs are hazardous to health

TRUE and FALSE No studies have shown any effect of GMOs (genetically modified organisms) on health and we remain rather vague. GMOs are from gene transfers, which naturally occur during conventional breeding species. The main risk is that they have an allergenic effect. Another risk GMOs resistant to herbicides and fungicides will also be more responsible for these substances puisqu'abondamment watered. Conversely, the GMO resistant to insects or parasites might be more healthy than conventional plants since have less need for pesticides. On the other hand, some researchers are working on GMO containing added vitamins or vaccines to developing countries.

GMOs are harmful to the environment

TRUE and FALSE The main risk of GMOs is their spread to surrounding cultures. This risk varies among plants and their mode of reproduction. On the other hand, we must distinguish different kinds of GMOs: GM herbicide resistant soybeans will lead to increased soil pollution because more material will be used. However, further research is likely to reduce pollution: such as insect-resistant plants. We should also mention the INRA research for the production of trees without lignin, a fiber whose elimination in papermaking is very polluting

Organic farming is better for health

FALSE Caution: do not confuse organic food and health food: organic will not make you lose weight! On the other hand, it does not present a major health benefit; Studies have even shown that there is abnormally high concentrations of mycotoxins in apples from organic farming, which has no right to use fungicides (the danger however is not proven, but it must know that organic products can be kept less and less time than traditional products). In contrast, organic agriculture, which does not use fertilizer, contributes to the preservation of soil and groundwater. In summary, buy organic for the environment and not for your health.

biodegradable plastic supermarket bags are a good solution

FALSE recent years, supermarkets offer biodegradable bags. If these are indeed less polluting since products made from corn or potato, they are not a sustainable solution. First, they are heavier than traditional materials, thus generating more pollution during transportation. But above all, the fact of encouraging consumers to use disposable products, is certainly not a sustainable policy ..

Industry is the main cause of pollution

TRUE and FALSE Of course, manufacturers are the first polluters, but we must not forget that their production is intended for consumers. And at the end of the day, it's a classic story of supply and demand. Each Frenchman is thus indirectly "responsible" for 3 tons of industrial waste per year. On the other hand, transport is for example the first emitter of greenhouse gases. Morality: let us question rather our purchasing behavior and our daily life.
