green skills 3

Question 1

Green jobs in solid waste management

Answer 1

• Solid waste is defined as any discarded solid fraction,
  generated from domestic units, trade centres,
  commercial establishments, industries, agriculture,
  institutions, public services and mining activities.
• Solid waste management system includes collection,
  segregation, transportation, processing and disposal of
  waste.
• Green jobs related to waste management are in
  areas like e-waste recycling, solid waste management,
  waste reduction, waste auditing, waste control, etc.

Question 2

Green jobs in appropriate technology

Answer 2

• of appropriate technology are
  bike-powered or hand-powered water pumps, solar lamps
  in streetlights, solar buildings, etc. It is the simplest technology that can get a job done in an environment
  friendly manner with locally available resources.
• biogas production, water treatment filtration,
  farm mechanisation, rainwater harvesting, sanitation,
  lighting, food production, refrigeration, etc.

Question 3

greenhouse gases

Answer 3

Some of the greenhouse gases are Carbon dioxide,
methane, Nitrous oxide, ozone and chlorofluorocarbons
(CFCs).

Question 4

greenhouse gases
info

Answer 4

• These are emitted due to burning of fossil
  fuels, using vehicles and refrigerants, and carrying out
  agricultural activities, etc.
• These gases can trap heat
  from the earth and prevent it from escaping into outer
  space. This causes the earth to heat, leading to ‘global
  warming’.
• To reduce the emission of greenhouse gases,
  people are working towards reducing the use of fossil
  fuels by finding less polluting energy sources, such as
  Compressed Natural Gas (CNG).

Question 5

In manufacturing plants and factories, managers try
to find various ways to reduce the amount of waste
produced at every step of the process. Here are some of
the ways.

Answer 5

• Reusing scrap material : - in paper mills, damaged rolls are
  sent back to the beginning of the production
  line, i.e., they are added as raw material
• Ensuring quality control: - If the quality of products is maintained, there will
  be a decrease in rejected products, thus, reducing
  waste.
• Waste exchange : -This is where the waste product of one process
  becomes the raw material for another.
• Managing e-waste: - With advanced technology, we have also
  encountered problems in managing e-waste like
  old mobile phones, laptops and television sets.
• Use of eco-friendly material: - Scientists have discovered various material,
  which are eco-friendly, for example, banana leaf
  and paper plates that are easily disposable, etc.

Question 6

Protecting and restoring ecosystems

Answer 6

• Ecosystem is the community of living and non-living
  beings existing together, and interacting with and
  supporting each other. It is the perfect balance where
  every species can survive.
• People are working now to help conserve the
  existing ecosystems and restore the degraded ones,
  using natural solutions. Forests and vegetation help
  stabilise slopes, and therefore, reduce the risk of
  landslides.
• Wetlands can help control floods. Avoiding
  cutting of forests, planting more trees, investing in
  soil health and restoration can control the emission of
  greenhouse gases.

Question 7

NAPCC

Answer 7

• The Government of India launched the National
  Action Plan on Climate Change (NAPCC) in June 2008
  to deal with climate change and related issues.
• The
  NAPCC comprises eight missions in specific areas of
  solar energy, enhanced energy efficiency, habitat, water,
  sustaining Himalayan ecosystems, forestry, agriculture
  and strategic knowledge for climate change, which
  address issues relating to mitigation of greenhouse
  gases and adaptation to the adverse impacts of climate
  change on environment, forests, habitat, water resources
  and agriculture.
