Ecology
Ecology is the study of the interactions of
organisms with one another and their physical
environment.
Biosphere
The Living Globe
The Biosphere is that part of the Earth in which life
exists.
Sustainability of the Earth System
•

There are many types of ecosystems in nature.
All ecosystems are interconnected.
Any change in one would affect on the other.
Even climate change would affect on the ecosystem.
So we have to protect sustainability of the Earth system.
NOW The Climate Change has
taken place…
The Earth is getting warmer….
What is Global Warming?
Global Warming is the rise in temperature of the
surface of the entire Earth.
Why is the Earth’s temperature
rising?
Human actions affect the Earth by releasing
more carbon dioxide into air along with
greenhouse gases into the atmosphere.
Greenhouse Gases
Carbon dioxide 30% increase
Source: Fossil fuel burning, deforestation
Methane 145% increase
Source: Rice cultivation, cattle & ship
Nitrous Oxide 15% increase
Source: Industry and agriculture (fertilizers)
Water vapor 35% increase
Source: Evaporation
% increase due to human actions
Greenhouse Gases
Carbon dioxide
Methane
Nitrous Oxide
Water vapor
What is Greenhouse Effect?
• Greenhouse gases are needed in the atmosphere to trap
the heat from the Sun so the Earth will not be cold.
• When the Sun hits the Earth, some energy gets trapped
by greenhouse gases like a blanket.
• Too little greenhouse gases, the Earth will too cold; Too
much greenhouse gases, the Earth will be too hot. So just
right amount of greenhouse gases will be OK for the
Earth.
• We are adding more greenhouse gases into atmosphere
every single day resulting warming the Earth more every
single day.
This is a
great problem

Human Actions!
Greenhouse Effect
Causes of Greenhouse Effect
Main cause of greenhouse effect is fossil fuels.
Any carbon-containing fuel coming from the decayed
remains of prehistoric plants and animals, e.g. coal, peat,
petroleum, and natural gas.
When we burn fossil fuels, carbon dioxide is released
into the atmosphere to add greenhouse gases.
The more fossil fuels are burned, the more greenhouse
gases are released.
That is why the Earth is getting warmer.
Fossil fuels are burned when we
-drive a car
-take the bus
-use electricity
-cook food
-travel by plane
-use hot water
-iron clothes
-watch TV
-have anything made of plastic
Fossil fuels are limited and are non-renewable. So
our current way of life is the real problem.
Impact of Global Warming
Increased respiratory health problems
Flooding
•
•
•
•
Global warming relocates rainfall.
Warmer air has more moisture.
Warmer oceans release more moisture.
Damage to societies.
Drought
• Dry areas will get dryer.
• Crops cannot be grown.
• Millions of people will have to starve.
Water Shortage
• Areas stricken by drought, will have less fresh water.
• Melting glaciers in mountains will provide water to millions of people
and animals.
• Water scarcity will life of people and animals will be at risk
• Global tensions will rise.
Spread of pests and disease
• Warm earth will carry diseases harmful to humans
and animals .
• Some of the pests will destroy the trees leading to
deforestation.
Famine
• Water shortage and drought will lead to famine.
• World will face a big problem.
Soil Erosion
• There will be nothing to hold the soil when a tree or
a plant is removed.
• Nutrients on the top layer will be washed away.
• It will be very hard to grow food.
• Millions of people will die of hunger.
Melting glaciers
• Melting glaciers will threaten water resources.
• When glaciers melt, sea level will rise.
• Darker land underneath will expose, suns heat cannot
be reflected and will be trapped to speed up further
melting.
Coral Reef Destruction
•
•
•
•
Ocean will absorb more carbon dioxide.
Acidic ocean will be dangerous for marine life.
Ocean ecosystem will be effecting.
Coral reefs and plankton will be damaged.
Fires
• Increased temperatures will and storms will
lead to severe fire forests.
• Carbon dioxide will be increased in the
atmosphere.
Species Extinction
• Change in climate will lead to many species to
relocate or extinction.
• Polar bear is already in dander situation.
Economic instability
Frequent natural disasters, droughts, water and
food shortages , troubled oceans, high sea level
will lead to economic instability among many
nations.
Solution of global warming
• Everyone of us should contribute and take action
immediately to save the Earth from global warming.
• Remember the three R’s- Reduce, Reuse, Recycle.
