Stewardship. Some
Christians believe God
made us stewards of the
earth. A steward looks after
something. Some
Christians believe they
have a duty to look after the
world and the living things
within it.
Homework. Find out and learn
the meaning of each of these
words.
Acid rain, fossil fuels, climate
change, global warming,
deforestation.
All : Identify and describe ways in
which humans can harm the
planet.
Most : Understand the harmful
effects of human activity upon
natural habitats.
Some: Explain why religious
people are concerned about these
environmental issues.

Environmental problems.
Some of the environmental problems we face today, such as droughts,
were known to our ancestors but are now experienced more
frequently. Others are new problems, resulting from modern
technology.
ACID rain
Rain has become more acidic because of the gases and fumes we
release into the atmosphere when we burn fossil fuels like coal. The
wind carries the air pollution from heavily industrialised countries
like Britain to other countries, where it falls in acid rain. This affects.
•Water in lakes and streams : fish and plants are killed.
• Trees: leaf loss and damage.
•Soil: soil erosion occurs when rains wash away soil which use to be
protected by tree roots and the leaf canopy.
•Buildings: some of the most beautiful buildings in Europe are
crumbling because of the chemical reactions with acid rain and stone.
•Health: contaminated water and food lead to illness.
Pollution of rivers and lakes
This is caused by agricultural, domestic and industrial waste. Such
pollution:
• Kills marine life
•Affects water quality causing health problems
•Makes rivers dirty and smelly
•Enters the food chain, and harms animals and humans.

Pollution of rivers and lakes
This is caused by agricultural, domestic and industrial waste. Such pollution:
Kills marine life
Affects water quality causing health problems
Makes rivers dirty and smelly
Enters the food chain, and harms animals and humans.
Modern farming methods
Using pesticides and fertilisers on agricultural land can:
Contaminate drinking water and human breast milk,
Kill wildlife.
Sea pollution
The sea is polluted by oil slicks, the dumping of industrial and domestic waste and
acid rain. Sea pollution leads to:
Toxic algae that kill marine life and contaminate seafood
Dirty beaches
Damage to seabirds, seals and other animals.

Sea pollution
The sea is polluted by oil slicks, the dumping of industrial and domestic
waste and acid rain. Sea pollution leads to:
Toxic algae that kill marine life and contaminate seafood
Dirty beaches
Damage to seabirds, seals and other animals
Modern farming methods
Using pesticides and fertilisers on agricultural land can:
Contaminate drinking water and human breast milk
Kill wildlife.
Global warming
The greenhouse gas we produce lead to global warming, which may
result in:
A rise in sea level, causing flooding and the erosion of coastlines
damaging homes, crops, livestock.
Having an impact upon the quality of peoples lives and even putting
people’s lives at risk.
Changes in vegetation and an increase in the number and size of deserts
Changes in migration patterns, intensifying droughts and flooding.
More extreme weather events such as storms and hurricanes
Other environmental issues include
•Extinction of species through over-fishing and hunting.
•Deforestation, the destruction of rainforests leading to the loss of species and climate change.
•Air pollution, which harms vegetation and humans.
•Toxic watse, which can affect the health of those who live near disposal sites.
•GM foods, genetically modified crops, which may affect the environment and human health
•Thinning of ozone in the upper atmosphere.
