Omega 3, whith Omega 6, are essential but we need to find it in the right food. Omega 3 needs for the protection of the circulatory system and for the prevention of cardiovascular diseases. The daily requirement of Omega 3 is, on average, about 3 grams.
Omega 3 is mainly contained in some types of fish, but we can find them also in some vegetables and legumes. Spinach, broccoli, lettuce and green cabbage, in addition to being very important sources of vitamins and minerals, also contain a small percentage of Omega 3.
Algae, very popular in Japan and other eastern countries, seaweed has now entered the market also in the West as an alternative food and with numerous nutritional virtues. Among these, there is also the richness of Omega 3.
About 30 grams of walnuts provide our body with almost 2 grams of alpha-linolenic acid (one of the fatty acids of the Omega 3 group). Linseed oil is by far the richest plant source in Omega 3 and the most useful for maintaining a balanced diet even excluding foods of animal origin.
Is the Amazon Rainforest contributing to global warming?
A research published in Frontiers in Forest and Global Change, as said by authors, is the first truly about the Amazon Rainforest is contributing to the global warming.
The results of the study said: "when we look at greenhouse gases as a whole, and not just CO2, the Amazon already produces more emissions than it captures. "Deforestation is interfering with carbon uptake, this is a problem.
But when you start considering these other factors along with CO2, it becomes really clear that the net effect is that the Amazon as a whole is really warming the global climate. We have this system that we have relied on to counter our mistakes and we have truly surpassed that system's ability to provide reliable service."
According to the study, the priorities are to curb deforestation in the Amazon, but also to reduce the construction of dams and increase efforts to replant trees. So the largest rainforest in the world has become a part of system of greenhouse gases, that is, it produces more emissions than it can absorb.
Climate change itself, along with deforestation, has a negative impact. Many studies in recent years have focused on the performance of the Amazon, on its ability to carbon sinking, that is, to sequester carbon from the atmosphere for long periods of time.
