Global Warming and Climate Change} Alfalfa, why is this crop so well suited for helping the planet?

Alfalfa is such a good cover crop for several reasons, first, it is a legume, which means that it can in association with certain bacteria, use the nitrogen in the atmosphere to produce a high protein crop that can be feed to many different land animals, and to many species of fish that mankind likes to eat. Second, it can be harvested from 3 times a year to as many as 11 times a year depending on where it is grown and how much water it receives, plus it is a perennial meaning that it will last up to twenty years before it needs to be replanted! ( Normally their needs to be another crop planted for a year or two to let the soil rebuild itself before replanting with alfalfa.) Alfalfa when dry can last many years in storage while keeping most of its protein in its leaves. Another plus is, its root system helps in maintaining the soils underneath from movement and loss due to dry windy conditions. Alfalfa was first cultivated around Iran and still can survive in dry hot climates. Being a cover crop it will covert more of the sun's energy to the production of alfalfa rather than letting the rays hit unprotected soils and heating up the surrounding areas. Since the whole plan is to convert most of the arid and semi-arid areas of the planet to some type of cover crop that will help use up the "extra carbon dioxide in the atmosphere" and reinstate the temperature regulating of the planet. It would not be prudent to plant too much of any one crop to prevent a disease from coming in and decimating the surrounding areas. Buffer zones are always a good idea and they present an excellent place for the development of new species of plants that may be from the  C4 or CAM family of plants? I do think that working in these types of places with soils that will need lots of work to become able to grow crops will lead to a new field of study in soil and plant biology in desert climates! That may be able to be transitioned to improve soils in tropical rainforest that have been burned and then left when the soils failed to support crops!

    When I first was talking about using c-4 or cam plants as a secondary ground cover it was only due to the fact that they are better use to dryer areas, but their resisperation process is much lower than c-3 plants and that is part of why using c-3 is better suited for increasing cloud cloud then either c-4 or cam plants. So using plants like pineapple would be a decent crop that would help both produce food and act as a buffer crop between c-3 plantings.

Global Warming and Climate Change} Lost of available carbon vs. too much C02 in atmosphere!

Global Warming and "The life cycle of a planet" By Daniel Kadavy  402-890-7946  Cortland Nebraska                                                                                                                                                                                                                The planet is running out of carbon, which is the mainstay of all life on the planet! Something has to be done to mitigate this. And yet Global Warming is changing ...

503 DIII Humanity is the only species that have to pay to live and survive. while there are a few exceptions to this rule, they are few and far between!

What does that say about how we live? It means that we have very little say in most aspects of our lives if we wish to live in a house, we must pay for that privilege with taxes, energy, insurance, maintenance, and keeping the standards that each place puts upon the owners, cutting grass, moving snow, and so many other requirements to fall within acceptable parameters of society! We must obey laws we may disagree with, nor have any input in their adoption or application! While there are many different arrangements of governments around the world, even the ones that are voted in or out of power by the masses are never truly fair in explaining to their constituents what they are going to attempt to do if elected! Yet this is the world we live in while we attempt to understand what 3.5 billion years of carbon sequestration have forced our planet to go through, including almost every single extinction event that has occurred in the history of our planet!  So the problem that we face is...

CCLXXIV Global Warming and Climate Change} Let's talk more, about the 50,000 gigatonnes of available carbon, that is left for all life on the planet!

First, how do scientist's come up with around 50,000 gigatonnes of available carbon left on the planet? Some of the amounts can be directly measured, how much there is in the atmosphere is one of the most researched numbers on the planet! That figure of 415 parts per million equals around 800 gigatonnes of carbon, in the form of carbon dioxide. 560 gigatonnes in plant and animal life are based on both satellite images for how much plant life is on the planet during the year and measurements that were taken by hundreds of people every year all around the planet. How much soil carbon, is taken by averaging soil carbon from all over the globe this amount is said to be 1,500 gigatonnes. The amount of "fossil Fuels" is the amount of "known" reserves found by mainly oil accompanying who has been looking as far and fast as they can, that amount is estimated at 4,000 gigatonnes (The carbon sequestrated in fossil fuels would only become available if mankind continues to ...
