2. 1) Human beings depend on
the environment

3. From biological perspective
Biotic (living) components cannot survive in
isolation, They must interact with physical or
abiotic (non-living) environments.

4. Human life depend on:
• Temperature
• Shelter
• Natural resources = substances and energy sources
needed for survival
• Renewable natural resources: can be replenished
– Perpetually renewed: sunlight, wind, wave energy
– Renew themselves over short periods: timber, water,
soil
• Nonrenewable natural resources: unavailable after
depletion
– These can be destroyed
– Oil, coal, minerals

5. • Ecosystem services: arise from the normal functioning of
natural services
– Purify air and water, cycle nutrients, regulate climate
– Pollinate plants, receive and recycle wastes

6. Human degrade ecosystem services and
create a environmental problem
By depleting resources,
destroying habitat,
generating pollution
Increased human
affluence has intensified
degradation

7. 2) Human being need to adopt
& modify environment
• Don’t disturb the nature
• Conserve water
• Conserve energy
• Grow more trees
• Recycle the wastage
• Ban the polythene
• Use renewable resources
• Save electricity
• Reduce the toxic waste
• Decrease usage rate of vehicles

9. 3) Factors which affects on the
climate and weather of Pakistan
• As Pakistan has, it's latitude and longitude is about
30 N and 70 E which makes it temperature fairly
warm.

10. • Deforestation
• Establishment of waters Dams
• Disturbing the way of river
• Geographical position
• Melting of glaciers
• Environmental pollution
• Usage of harmful technologies e. g.
Drone Attacks, Booms, Machine Guns etc.
• Solar Radiations
• Flood, Earth quack,
• Lack of proper place for wastage of factories

11. Conclusion
“Humanity is dependent upon an earth incapable of
supporting infinite demands, and capable both of
being improved and of being damaged by the way in
which it is used”
