Section 2 - Environmental and Medical Issues Flashcards
What is global warming?
The increase in the temperature of the Earth’s atmosphere
What is the greenhouse effect?
The burning of fossil fuels which produces CO2 and forms a barrier in the atmosphere. Sun can get in but not out
What is natural climate change?
That the Earth’s climate changes naturally
What natural sources are said to produce large amounts of CO2?
Volcanic emissions, animals, bacteria, ocean and decaying vegetation
How are alternative ways of producing electricity helping the Earth?
Ways such as solar power, wind power and hydroelectric power produce no CO2 emissions
How are car manufactures helping to solve global warming?
Using electric, bio-diesel and ethanol batteries –> Improves the efficiency of the cars -> producing less CO2
What methods produce the most and least amount of CO2?
Least = Train by far Most = Planes by far
What is a possible solution to acid rain?
Use less fossil fuels
What is a possible solution to human waste?
recycling, using incinerators to produce electricity, sewage to provide methane or fuel in power stations
What is a possible solution to eutrophication?
Improved sewage treatment, less use of phosphates in detergents and nitrates in fertilisers
What is a possible solution to radioactive pollution?
Reprocess as much nuclear waste as possible, geologically dispose of radioactive waste
Why is it important to try and find solutions to radioactive pollution and human waste?
As it is a hazard to humans
What are renewable resources?
Resources which can be used over and over.
What is a problem with renewable resources?
Much more expensive than burning fossil fuels
What are non-renewable resources?
Resources which disappear once used
What is a possible solution to non-renewable resources and name an example
Renewable resources e.g solar, wind, tidal, sea and hydroelectric power
How are car manufacturers trying to help the scarcity of natural resources?
Looking at water, sugar cane, electric and hydrogen batteries
How is scientists trying to help the scarcity of natural resources?
Using chemicals from plants rather than oil to produce things e.g plastics
How could you change your lifestyle to help the scarcity of natural resources?
eat organic foods, wear cotton/wool clothes and ride bikes/walk
What is conservation?
Protecting and preserving the natural resources and the environment
What is creation?
The act of creating the universe, or the universe which has been created
What is the environment?
The surroundings which plants and animals live and which they depend on to live
What is stewardship?
Looking after something so it can be passed on to the next generation
What did the Old Testament teach about the environment and what humans should do to protect it?
- Humans have a responsibility to treat animals humanely
- Treat the land kindly -> Not growing crops ever 50th year
What does the parable of the talents and minas teach?
Humans should pass on more to the next generation than they have been given
Why do many Christians believe it is important to follow stewardship?
- Jesus taught it
- Will be part of judgement on how they have fulfilled their duty on earth
