Disadvantages of technology
- Human had misused the technology and used in damaging purpose.
- By the use of technology, man is doing illegal things.
- New technology like mobile are generating bad consequences on children.
- By means of modern technology, terrorists use it for destructive purpose.
- Many illness are created due to the development of atomic energy and atom
bomb. - Modern technology like nuclear energy have not only affected man but it also
affected pants and other creatures. - Natural beauty is decreasing due to the development of modern technology.

8. The impact of economics
9. The influence of politics
The law of physics have 2 effects
Quantum Effects
Thermodynamic effects
LAw OF PHYSICS
have theoretical and practical limits to
information capacity: you cannot store more memory that there are number of elementary particles in the universe
Quantum effects
LAW OF PHYSICS happen when the containers that
will dissipate heat limits its use
thermodynamic effects
The Laws of software and algorithm
2 limitations
Software limitations
limitations for algorithm
The Laws of software and algorithm
can’t do, can’t afford, and don’t know
how to do a given computation
Software limitations
The Laws of software and algorithm
theoretical limits of compressing an
image, a waveform, video, or some raw stream of bits, some degree of information loss, hairy mathematics, some trial and
error, and lack of perfect knowledge adds complexity and compromise to our systems
Limitations for algorithm
A distributed system is one in which the failure of
a computer you didn’t even know existed can
render your computer unusable”
The Difficulty of Distribution
The design of any relevant Web-centric
system consists of tens of thousands of lines
if middleware code on top of several million
line of operating system code.
The Problems of Design
limitations of The Problems of Functionality
Limitations: usability,
survivability, and adaptability
A software system could not be understood by just one
person alone.
* It demands a team of developers.
The Importance of Organization
what is The Impact of Economics
Technological advancement costs money
The political organization can influence the
progress and limitations of software development.
* Great things could have provided if the influence
in politics are on a positive side.
The Influence of Politics
It is the variety of life forms at structural
levels (genetic, species, and
ecosystem).
LIFE ON EARTH
BIODIVERSITY
3 kinds of biodiversity essential to preserve
ecological systems:
Genetic Diversity
Species diversity
Ecosystem diversity
kinds of biodiversity essential to preserve
ecological systems:
a measure of the variety of versions of THE SAMEGENES within individual species
genetic diversity
kinds of biodiversity essential to preserve
ecological systems:
describes the number of different
kinds of organisms within
individual communities or
ecosystem
species diversity
kinds of biodiversity essential to preserve
ecological systems:
specifies the number of niches, trophic
levels, and ecological processes that
capture, sustain food webs and recycle
materials within this system
ecosystem diversity
Importance of biodiveristy
It can aid ecosystem stability and because we
rely on many different organisms
has medicinal properties that the researchers could be used to treat cancer, fever, malaria, and rheumatism
Biodiversity can aid ecosystem stability
Aesthetic and existence values are important
- it provides job opportunities to local communities
- nature-based activities like fishing, hunting, camping
and hiking also have cultural value
- it has religious and moral significance
threats to biodiversity
Extinction, the elimination of species,
can be a normal process of the
natural world as species out-compete
or kill off others or as environmental
conditions changes
Over the past 150 years, due to
HUMAN ACTIVITIES, extinction rate
has increased from rate of 1 - 5 per
year to thousands per decade.
HIPPO
Habitat destruction
Invasive species
Pollution
Population of humans
overharvesting
is a biogeographic region with significant
levels of biodiversity that is threatened by human habitation
Biodiversity hot spots
To qualify as a biodiversity hotspot, a region must meet
two strict criteria:
1.) It must have at least 1,500 vascular plants as
endemics
2.) It must have 30% or less of its original natural
vegetation. In other words, it must be threatened.

IMPACT OF GMO TO BIODIVERSITY
AND ENVIRONMENT
An insect resistant GM crop could have direct toxic effect on
non-target species.
A GM crop could have an indirect effect to other species by
reducing the source of food for other wildlife such as birds.
Pest resurgence could be resulted from insects which
become resistant to chemicals when used on pest tolerant
GM crops repeatedly and may increase the number of insect
pest.
Creating an imbalance in nature by changing the
predatory/prey ratio.
Average temperature (at present) of earth’s surface
15 degree Celsius/59 degree Fahrenheit
According to EPA, what are the greenhouse gases
Carbon dioxide
methane
nitrous oxide
fluorinated gases
A greenhouse gas that is primarily emitted by burning fossil fuels (coal. natural gas, and oil), solid waste, trees and wood products.
carbon dioxide
a greenhouse gas , emissions are from livestock, agricultural practices, and the decay of organic waste. Production and transport of fossil fuels also release it
methane
a greenhouse gas, agricultural and industrial activities and combustion of fossil fuels and solid waste are its primary source
nitrous oxide
A greenhouse gas, also known as High Global Warming Potential (GWP) gases; synthetic powerful greenhouse gases from the emissions of industrial processes. It includes hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride and nitrogen trifluoride.
fluorinated gases
sources of greenhouse gases (6)
Electricity production.
Transportation.
Industry.
Commercial and Residential,
Agriculture.
Land use and Forestry.
impacts of enhanced global warming
More frequent hot days and fewer cool days
More intense heat waves
Worsening storms, floods and droughts
Intensified Hurricanes
Warmer ocean surface temperatures
Rising sea levels
More frequent coastal flooding
Island nations disappear
Accelerated melting of ice sheets and glaciers
Changes in the growing season of plants
Disruption of normal ecosystem
Loss of animal habitat
Possible extinction of animals
PROJECTED HEALTH IMPACTS of CLIMATE CHANGE
Increase malnutrition and consequent disorders.
Increase in the number of people dying and suffering from disease and injury due to heat waves, floods, storms, fires, and droughts.
Continue change range of some infectious disease vectors.
Have mixed effects on malaria
Increase the burden of diarrheal diseases.
Increase cardio-respiratory morbidity and mortality associated with ground-level ozone.
One way to determine a person’s environmental impact is through__?. It is usually expressed in equivalent tons of Carbon Dioxide (CO2). It calculates the sum of all the produced carbon induced by a person’s energy use. Awareness of personal carbon footprints can help reduce energy consumption leading to minimized carbon emissions production.
Carbon Footprint computation
