Man's Impact on The Environment
Interaction of Man with Environment
Man depends on the environment for natural resources
Sunlight
Air
Forests
Fossil Fuels
Land
Water
Metal
Minerals
Man needs natural resources to get
Food
Materials
Energy
They have
Positive
Negative
Impacts on the environment
Negative Impact of Man's Activities on The Environment
Deforestation
Clearing of large areas of forested area land by
Cutting
Burning
Purpose
To allow people to dig up
Minerals
Fuels
For wood to make
Paper
Furniture
To provide land for people for
Agricultural Use
Urban Use
Process
Trees are cut down
Animals lose their habitats
They become exposed to
Predators
Weather
After-effects of Deforestation
Loss of Living Things
Plants and animals may die because they are burnt
Smoke makes it hard for the living organisms to breathe
Less carbon dioxide is absorbed by trees
More carbon dioxide is in the atmosphere
Trapping more heat
Causing global warming
No more trees can hold the soil together
Soil erosion occurs because soil is washed away by rainwater
Soil blown away by wind
Difficult for new plants/trees to grow
Fewer trees to absorb water from the soil
Less water released back into the air
Less clouds in the sky
Less rain
Land becomes more dry
Pollution
Caused by releasing pollutants into the environment
A pollutant is a substance that makes the environment
Dirty
Harmful to live in
Can affect
Land
Air
Water Bodies
Pollutants
Litter
Pollutes
Land
Water
Attracts
Disease-causing organisms
Pests
Chemicals
Insecticides
Weedkillers
Pesticides
May be washed into water bodies
They kill aquatic organisms
Poison the water
Humans are unable to use it
CFC
Used in
Aerosols
Fire Extinguishers
Refrigerators
Make the ozone layer thinner
Untreated Human Waste
Released into water bodies
Make water unsafe for drinking
Smoke
Produced by
Burning oil
Coal
Wood
Processes in
Vehicles
Machines
Factories
Contains pollutants
Makes air difficult to breathe in
Cigarette Smoke
Contains substances that pollute the air
Harmful to health
Haze
Caused by burning forests
Acid Rain
Formed when pollutants from smoke dissolve in the rain
Damages
Buildings
Outdoor structures
Can kill
Trees
Aquatic Organisms
Pollutes our water supply
Depletion of Natural Resources on Earth
Fossil Fuels
Energy source for
Vehicles
Factories
Metals
Minerals
Energy source for
Utensils
Jewellery
Machines
Trees in Forests
To obtain wood for
Furniture
Paper
Fish
For food
Overfishing may cause extinction of the population of fish
Global Warming
Certain gases in the Earth's atmosphere
Like carbon dioxide
Trap heat from the Sun
This warming effect is
The greenhouse effect
Keeps the Earth from freezing
Greenhouse gases are given off as an effect of
Deforestation
Burning of fossil fuels
Too many greenhouse gases
leads to the surface of the Earth becoming much warmer
More heat is trapped
Global warming occurs
Ice caps at the Poles melt
Sea levels rise
Places near the sea will be flooded
What Man can do to make a Positive Impact on The Environment
Conservation of Natural Resources
Reducing
Reduce use of fuels
Effects
Conserves natural resources
Reduces production
Greenhouse gases
Smoke
Take public transportation
Walk short distances
Reduce amount of litter produced
Effects
Conserves natural resources
Reduces pollution of
Land
Water
Use products with less packaging
Bring own shopping bag
Reusing
Reusing products
Conserves natural resources
Reduces pollution
Recycling
Plastics
Shopping Bags
Effects
Conserves natural resources
Reduces pollution of
Land
Water
Glass
Jars
Metal Products
Aluminium Cans
Reforestation
Restore the forests and wildlife
Reduce CO2 and global warming
