10. 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.[

11. 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.

12. 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.

17. Assam, India: Micro Hydro Power Project to Benefit 38 Families

18. It has a 12-foot-high water reservoir and a turbine.
Inhabitants of a remote village in the rugged, mountainous terrain of North Cachar Hills are getting uninterrupted power supply even though it is not connected by conventional power grid.
This has been made possible by the State’s first micro hydro-electricity.
The project generates 6.8 KVA power from a hilly stream called Boro Robi nullah near the hamlet.
It has a 12-foot-high water reservoir and a turbine.
“This was started as a pilot project with support from the Army, and following its successful implementation, we plan to set up more such micro hydel projects in similar terrain in the district,” HP Rajkumar, Project Director, District Rural Development Agency (DRDA), NC Hills, said, adding that a couple of sites had already been identified for the purpose.
Rajkumar said that the Army engineers designed the turbine, which cost Rs 1.25 lakh. “The Army has been very enthusiastic about the project and extended every possible cooperation to us.
We got technical expertise from the IIT-Delhi as well,” he said.
At the moment the project is illuminating 38 households of the village besides a school, a church, a temple and an auditorium. “The households have two bulbs each.

19. Are the Humans created to disrupt the Nature????!!!???
Let us understand the special bio-energetic characteristic of Humans….

20. Thermodynamic Classification Living Species
Life on Earth
Autotrophs
Heterotrophs

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

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

23. Carbon Cycle With Autotrophs and Somatic Heterotrophs

24. 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.
