it is about the environmental issues done by human being and spoil our environment. here i present some issues which is dangerous for our environment. effects of this issues are also mentioned in ppt this ppt is useful for people who want a change in our environment.

2. What is environmental issues?
 Environmental issues are harmful effects of human
activity on the biophysical environment.
 Our activity harms our environment badly. Because of
that our environmental system get disturbance.
 Environmental protection is a practice of protecting the
natural environment on individual, organizational or
governmental levels, for the benefit of both the
environment and humans.
 We have to know importance of environment safety
because of that our subject ES is here.

3.  Environment destruction caused by humans is a
global problem, and this is a problem that is on going
every day.
 The global human population is expected to grow by
2 billion people, thereby reaching a level of 9.6 billion
people in near by 2050.
 Major current environmental issues may include
climate change, pollution, environmental
degradation, and resource depletion etc. here a list
of environmental issues or effects of human activity
on environment.

4. List of Environmental issues?
 Human overpopulation
 Hydrology
 Intensive farming
 Land use
 Nanotechnology
 Natural disasters
 Nuclear issues

5.  Human overpopulation: Human overpopulation
occurs when the ecological footprint of a human
population in a specific geographical location
exceeds the carrying capacity of the place occupied
by that group.
 Hydrology: Hydrology is the scientific study of the
movement, distribution, and quality of water on Earth
and other planets, including the water cycle, water
resources and environmental watershed
sustainability.
 Intensive farming: Intensive farming or intensive
agriculture is any of various types of agriculture that
involve higher levels of input and output per unit of
agricultural land area.

6.  Land use: Land use involves the management and
modification of natural environment or wilderness
into built environment such as settlements and semi-
natural habitats such as arable fields, pastures, and
managed woods.
 Nanotechnology: Nanotechnology is manipulation
of matter on an atomic, molecular, and
supramolecular scale. Nanotechnology as defined by
size is naturally very broad, including fields of
science as diverse as surface science, organic
chemistry, molecular biology, semiconductor physics,
microfabrication, molecular engineering, etc.

7.  Natural disaster : A natural disaster is a major
adverse event resulting from natural processes of
the Earth; examples include floods, hurricanes,
tornadoes, volcanic eruptions, earthquakes,
tsunamis, and other geologic processes.
 Nuclear issues : to get a energy the nuclear fusion
process is there but the nuclear leakage is makes
our environment pollute and it is harmful for our eco
system.

9. Effects on environment:
 Climate change : climate change is a change in the
statistical distribution of weather patterns when that
change lasts for an extended period of time .Climate
change may refer to a change in average weather
conditions, or in the time variation of weather around
longer-term average conditions.
 Global warming• Global dimming• Fossil fuels• Sea
level rise• Greenhouse gas• Ocean acidification•
Shutdown of thermohaline circulation•
Environmental impact of the coal industry• Urban
Heat Islands• Flooding

10.  Environ mental health :Air quality • Asthma • Birth
defect • Environmental impact of the coal industry
• Environmental impact of nanotechnology •
Electromagnetic field • Electromagnetic radiation
and health • Nature deficit disorder • One Health •
Sick Building Syndrome • Environmental impact of
hydraulic fracturing

11.  Overpopulation: Overpopulation occurs
when a species' population exceeds the
carrying capacity of its ecological niche. It can
result from an increase in births a decline in
the an increase in immigration, the increase
of homosexual males or females.
 Burial • Overpopulation in companion animals
• Tragedy of the commons • Gender
Imbalance in Developing Countries • Sub-
replacement fertility levels in developed
countries

12.  Pollution: pollution is the introduction of
contaminants into the natural environment that
cause adverse change. Pollution can take the form
of chemical substances or energy, such as noise,
heat or light. Pollutants, the components of pollution,
can be either foreign substances/energies or
naturally occurring contaminants.
there is many types of pollution is in our
environment , here some type of it.
 Air pollution
 Soil pollution
 Water pollution

13.  Air pollution: • Environmental impact of hydraulic
fracturing• Indoor air quality• Smog• Biological • •
Light pollution • Visual pollution • Noise pollution
 Soil pollution : Alkali soil• Brownfield• Residual
Sodium Carbonate Index • Soil conservation• Soil
erosion
 Water pollution : Acid rain• Agricultural runoff•
Environmental impact of the coal industry•
Environmental impact of hydraulic fracturing• Fish kill
• Groundwater pollution• Groundwater recharge•
Marine pollution• Nutrient pollution • Ocean
acidification• Oil spills

14.  Waste : waste and wastes are unwanted or
unusable materials. Waste is any substance
which is discarded after primary use, or it is
worthless, defective and of no use
 Electronic waste • Great Pacific Garbage
Patch • Illegal dumping • Waste disposal
incidents • Marine debris • Medical waste•
Toxic waste • Environmental impact of the
coal industry • Exporting of hazardous waste
