Situation:
Caring for the environment has become a top priority due to the effects of climate change. Suggest some ways to care for the environment.
Candidate A - Talk about the importance of recycling
1. Conserve natural resources
reduce the usage of new resources – trees and forests, petroleum, metals, etc – reduce the greenhouse effect
natural resources – limited/finite – some are in very short supply
2. Reduce pollution caused by waste
harmful chemical and greenhouse gases - released from rubbish in landfill sites – contaminate water and soil
waste – not biodegradable - recycling papers, plastics and metals – help to reduce pollution
3. Save energy
making products from recycled materials – requires less energy on sourcing and processing
reduce carbon dioxide and other greenhouse gases – vital for stopping disastrous climate change
Candidate B - Talk about the importance of reducing air pollution
1. Reduce harmful / noxious gases
poor air quality has harmful effects on human health & environment – asthma, coughing and other respiratory diseases
improve the quality of the air – allow people to live in a healthier environment
2. Reduce carbon emissions from vehicles & factories
reduce or prevent formation of acid rain
harmful effects on infrastructure, plants, animals and human – corrosion of steel, causing irritation to eyes and nose
3. Increase visibility
smoke and haze emitted from vehicles, factories and open burning reduce visibility
affect daily routines and health
Candidate C - Talk about the importance of reducing deforestation
1. Give the forests time to regrow and heal
forests are necessary for stabilising climate – decrease average temperature of our planet
provide oxygen for us to breathe – remove carbon from the atmosphere – reduce effects of global warming
2. Preserve habitats of animals
most animals live in forest – cutting down trees – leading cause of animal extinction
destroy habitats of animals – places where they live, hide, lay eggs or birth
3. Protect forest ecosystem
give endangered flora and fauna a chance to repopulate
flora and fauna – sources of food for animals – important to sustain it
Candidate D - Talk about the importance of reducing water pollution
1. Improve the quality of water
water – essential and general need of life
must control the amount of toxins released into rivers and sea - safe for human consumption
2. Protect our marine environment
reduce harmful algae growth – increase oxygen levels in the water
create healthy ecosystem for aquatic animals
3. Improve the quality of fishery products
pollutants – chemicals, oil, heavy metals, acids - released into rivers and sea can be dangerous
pollutants can enter our food system – eating contaminated seafood – cause health problems
