4. What is nature conservation?
 Nature conservation is the wise management and utilization of natural
renewable resources in a sustainable manner to ensure the
maintenance of biodiversity. There is an increasing awareness that the
conservation of the world’s natural resources is vital for human
survival; thus the growing interest in conservation as a career.
How is engineering involved in the process
of nature conservation?
 Here the role of environmental engineers comes into the play.
Environmental engineering refers to the use of scientific processes to
help improve the earth’s environment to provide healthier land, water
and air for human use and to find ways to scale back on pollution
sites. The main focus is to use the principles of engineering, biology
and chemistry to develop solutions to environmental problems.

5. Current problems regarding nature conservation
 Protecting water :- to protect rivers, lakes and water sheds.
 Action on climate change :- to reduce emissions to levels compatible with at
healthy planet. Preserving forests and help
nature adapt to global warming.
 Conserving land :- Sustaining the world’s land resources, to unlock
the true potential for green growth.
 Waste disposal :- The over consumption of resources and use of
plastics create a global crisis of waste disposal.
 Deforestation :- Clearing of green cover and making that land
available for residential, industrial or
commercial purpose.

6.  Ozone layer depletion :- Ozone layer prevents harmful UV radiation from
reaching the earth.
 Pollution :- Pollution of air, water and soil. Industry and
motor vehicle exhaust are main reasons of air
pollution. Water pollution is caused by oil spill,
acid rain and urban runoff. Industrial and day
today human waste pollutes the soil and
deprives it from essential nutrients.

7. What is Environmental Engineering?
 It is a branch of engineering connected with
the application of scientific and engineering
principles which affects the environment.
Objectives of Environmental Engineering.
 Find solutions for environmental issues like,
 Energy preservation.
 Protection of assets.
 Controlling of waste from human & animal activities.

8. It involves,
 Waste water management & disposal.
 Air pollution controlling.
 Recycling
 Environmental sustainability.
 Public health.
They address local & environmental issues such as, effects of,
 Acid rains
 Global warming
 Ozone depletion
 Water/Air pollution
 Industrial sources

10. Who is a civil engineer?
 “Civil engineers are being called on to develop
integrated (system of systems) strategies to
ensure that not only movement of people and
goods is efficient but also,
strategies for resilient
power supply, management of water resources and
for treating waste as a resource”

11. How to do it?

12. What can be done?
 Wastes from demolition of building and structures.
 Eliminate
 Reduce
 Reuse
 Recover
 Dispose
 Use of sustainable building materials
 Energy consumption and green house

13. What is Green Engineering?
 Production of energy & materials from
“green feed-stocks”, such as bio mass &
microorganisms with the intention of
reducing energy waste & GHGs.
 GHG migrations presents opportunities for chemical
engineers to dense quantify and implement innovative
green solutions.

14. This can be done by,
 Identifying and evaluating options & resources usefully to
support green engineering. Significant & invaluable
improvements can be gained.

 New plant considerations
 Assess your existing facilities
 Know your options

16. Summary & Conclusion
 Engineers bear some responsibility for the destruction of the
environment.
 Nature conservation is an extra cost for an industry.
 Businesses are all about lowering cost and making profits.
 So they always find loop holes in rules & regulations that protect the
nature or simply ignore them.

17. Summary & Conclusion
 Engineers are searching for more & more methods to conserve nature.
 To make a difference everybody should understand the value of nature
& its current state.
 Let’s make a conscious effort to conserve the nature.
