Some of the  earliest  plants which evolved to bear seeds   Gymnosperms ( like cycads) did not have their ovules covered in the ovary.  They called it naked ovules.   They  were even borne on the leaves in some species which are now represented in  fossil records. Covering the ovules in a cover of ovary which is modified leaf in broadest sense was sign of  evolution in plants.

 "In a major eco-friendly step towards renewable energy generation in India, seaweed sourced ethanol (ethyl alcohol), a biofuel additive in transport fuel, has been used to run a car for the first time. Central Salt and Marine Chemicals Research Institute (CSMCRI) in Bhavnagar scientists recently drove an ambassador car with a fuel blend of 10 per cent ethanol and 90 per cent petrol.

While this green fuel is already produced and used to run cars in some countries, specially US and Brazil, in India, this was not possible as sugarcane, the main source of ethanol, is a food crop here. To counter this disadvantage, CSMCRI has become the first Indian body to successfully produce ethanol from a seaweed, Kappaphycus alvarezii.

Besides petroleum products below the earth , 97 percent of water is saline on the surface of the earth and major portion of water is obtained from water reserves below the ground. Excessive use of water results in lowering of water table and rocks below the earth surface which were submerged in water layers get exposed and release different heavy metals. Like arsenic is released in wells of Kolkatta region and elswhere as per some reports.

Some weeks ago I posted a blog Falodi ( Jodhpur Rajasthan India ) and Jaisalmer and Jodhpur recorded 49.9 degree or almost this temperature and yesterday there was news that floods have come there and army has to be called to evacuate people.It is not water scarcity but its poor management which is responsible for the loss of water from the surface and ground level. Here in Germany people have water storage tanks and store rain water and also harvest used water and use it for toilets and garden.

Increasing levels of Carbon d ioxide may promote photosynthesis some time somewhere and have adverse effects in times to come, however population explosion is happening now and here. See the water tables going down, forests vanishing, billions of people living  in abject poverty, sleeping hungary overexploiting water resources causing salinization, soil erosion, and reduced agricultural production are all population based problems .It is unequal growth of world populations which may pose threat to world peace. Populations are not growing in some countries and some countries are population production assembly line running day and night with no holidays on production of human beings. Does it go faster on holidays ?

What one wants to say what one really says and what one wants to hear and what other person really says ? With civilization covering our bodies with clothes in different parts of the world our ideas also got a covering of shyness , crookedness, wickedness depending on the level of civilization from medivel times to most modern times.

Cant we develop some machine to reach to the neurons to read what one is saying and what one is wanting to say but hiding his feeldings.

If we start reading minds of each other it will be catastrophe as most of the emotions are hidden and true feelings are seldom expressed.
