  6. Cow Brain Protein Could Build Better Batteries and Solar Cell Cow • Researchers at Stanford are exploring the idea that clathrin, a protein found in cow brains, can form nanostructured inorganic material for use in solar cells and batteries. • Unlike synthetic materials used in energy tech that require nasty chemicals and high temperatures to form specific shapes, clathrin can be tweaked at room temperature and pressure. • If all goes well, next-generation solar panels may very well contain traces of cow brain.

  7. Continuous Evolution of Homo Sapients • Raw food eating habits to Micro wave based cooking. • Human and animal vehicles to Automobiles. • Watching a flying bird to flying like a bird at high speeds. • Manual machines to Electric appliances. • Living with available seasonal food to eating anything at any time. • Spending hours on paper note book calculations to High speed computing note book. • …………… • ……………… • ………………………

  8. Human impact on the environment • Human impact is called as an anthropogenic impact. • The term anthropogenic designates an effect or object resulting from human activity. • The anthropogenic impact on the environment includes impacts on biophysical environments, biodiversity and other resources. • The atmospheric scientist Paul Crutzen introduced the term "anthropocene" in the mid-1970s. • The term is sometimes used in the context of pollution emissions that are produced as a result of human activities but applies broadly to all major human impacts on the environment.[

  9. State of ecosystems, habitats and species • In the past, human interaction with nature, enriched the quality and variety of the living world and its habitats, although having a disruptive effect on nature. • Today, however, human pressure on natural environments is greater than before in terms of magnitude and efficiency in disrupting nature. • The policies pursued in the industry, transport and energy sectors having a direct and damaging impact on the nature. • The strong focus of forestry management on economic targets primarily causes the decline in biodiversity, soil erosion and other related effects.

  10. Manifestations of the degradation • The clearest manifestations of the degradation of the natural environment are: • Reduction and fragmentation of habitats and landscapes. • A decreased species diversity, due to reduced habitable surface area which corresponds to a reduced "species carrying capacity". • The reduction of the size of habitats also reduces the genetic diversity of the species living there. • Loss of Species of Fauna and Flora. http://www.hobart.k12.in.us/jkousen/Biology/impact.html

  11. Thermodynamic Classification Living Species Life on Earth Autotrophs Heterotrophs

  12. Earth, Life and Energy • Life on Earth is driven by energy. • Autotrophs take it from solar radiation and create Energy Reservoirs on Earth.

  13. Creators and Exploiters of Energy Reservoirs Heterotrophs take it from autotrophs.

  14. Carbon Cycle With Autotrophs and Somatic Heterotrophs

  15. Energy and Human Evolution • The humans are extrasomatic heterotrophs. • The ability to use energy extrasomatically enables human beings to use far more energy than any other heterotroph that has ever evolved. • The human population modified more and more of its environment by using extrasomatic energy to suit human needs. • The world's present population of over 5.5 billion is sustained and continues to grow through the use of extrasomatic energy. • The human race expanded its resource base so that for long periods it has exceeded contemporary requirements.
