CHRISTIAN APPROACHES TO SELECTED ISSUES
RELATED TO MODERN SCIENCE, TECHNOLOGY AND ENVIRONMENT
DEFINITIONS
Science – subject field that deals with a systematic study of our surroundings and behaviour of materials in the universe
It is based on observation, experimentation and measurement.
Technology – application of science to achieve desired objectives.
Environment – our surroundings – both natural and human made i.e. mountains, lakes, land, forests,animals, buildings, flowers etc
POSITIVE AND NEGATIVE EFFECTS OF SCIENCE AND TECHNOLOGY
Ways science and technology has improved human lives
- Improvement of crop production – a quality seeds, fertilizers leading to improved yields
- Better nutrition, health care, medical services
- Improvement of livestock production through artificial insemination, quality medicine leading to more milk production.
- It has led to development of efficient means of transport – land, air, seas
- Work has been made easier and enjoyable. There is use of machines, automation, use of computers.
- People’s lives have been spared, saved e.g. through life saving machines (ICU), incubators
- Business transactions are being done through the internet
- Communication has been made easy – fax, email, short text messages on mobile phones etc
- Research is ongoing for incurable diseases i.e. HIV / AIDS, cancer
- There is better management of environment
- Technology has made the world a global village
- Through family planning methods, its easier to control population growth
- There’s a better security system through use of scanners, alarms, electrified fences etc.
- Improvement of learning through e–learning
- There’s easier movement from one country to another
CHRISTIAN APPROACHES TO SELECTED ISSUES
Negative effects of science and technology
- People use medicine to commit suicide
- Increase of crime, fraud and death through modern means of communication
- Destruction of family relationships
- Breakdown of community names, values morals, breakdown of families
- Terrorism
- Greed for money / materialism
- Unemployment – replacement of personnel by machines
- Health hazards such as accidents in factories
- Pollution, air poisoning
CHRISTIAN VIEW ON ISSUES RELATED TO SCIENCE AND TECHNOLOGY.
- Euthanasia
- Blood transfusion
- Organ transplant
- Genetic engineering
- Plastic surgery
- Euthanasia
It’s a Greek word, which means an easy and painless death. It is ‘mercy killing’ ending a person’s life so as to alleviate them from experiencing pain.
- Its practiced with the sick person’s knowledge
- It is involuntary when its practiced against or without the sick person’s consent
- Its done by
- Injecting an overdose of sleeping pills to the sick person
- Switching off life support machine
- Exposing the person with chronic pneumonia to very cold air.
CHRISTIAN APPROACHES TO SELECTED ISSUES
Christians view on Euthanasia
Christians are opposed to euthanasia for several reasons such as
- Life is sacred, a gift from God and only God can take away human life
- Suffering is part of human life
- Euthanasia is against medical ethos, which demands that doctors and nurses work for the sustenance of human life and alleviation of suffering but not to terminate it.
- Jesus has power over sickness and through his name all sickness are healed
- Accepting euthanasia discourages medical research on vaccines that may cure various diseases.
- Euthanasia discourages patients and makes them to lose hope in life. They may feel unwanted and rejected.
Blood transfusion
– It’s the process of injecting a person’s blood into another person through his/her veins. The giver is a donor the receiver is a recipient.
Reasons for blood transfusion
- When a person is suffering from acute anemia (little blood in the body) low blood level.
- To restore blood lost during fatal accidents, wars, or childbirth
- To maintain blood levels for patients undergoing major operations
- To correct the low haemoglobin level of some patients
- Blood has to be screened for any diseases, and then kept in blood bank after determining the blood group. The transfusion should be in a hygienic way. The equipment used should be sterilized
- Donors should not be below 16 years or above 65 years
Alternatives to blood transfusion
- Volume expanders – increase fluid levels in the body
- Growth factors – intra operative / post operative
- Blood salvage – same blood when on surgery is saved then transfused back to the patient Christian view on blood transfusion
CHRISTIAN APPROACHES TO SELECTED ISSUES
Christians approaches to blood transfusion
- Some Christian’s believe it is wrong to take blood from a healthy person and transfuse it to another person.
- Blood is life and life cannot be taken from one person to another
- Blood transfusion is essential as it saves life
- Blood transfusion can transmit dangerous diseases like HIV / AIDS and Hepatitis B
- God has given Christians the intelligence and capability to make the right decision and choice
Organ transplant
– This is the removal of a defective organ and replacing it with a healthy one. Body organs transplanted are kidneys, heart and eyes small intestines, pan crease.
– The purpose is to replace the damaged organ of a recipient
– Common transplants are the heart, kidney, eyes from living and the dead (heart) within a span of hours. Eyes can be transplanted from animals.
Christian view on organ transplant
- It saves life hence acceptable to some
- Its transferring human life from one person to another
- Its wrong to transplant from animals – view by some Christians
- Some support organ transplant by referring to the story of creation of Eve from parts of Adam
- It is part of human beings continuing with the creation work of God.
- It is an expression of love and concern for those suffering as taught by Jesus Christ.
Genetic engineering
– It’s a scientific technique used by scientists to change the biological characteristics of living organisms by deliberately altering the structure of individual genes.
– There are genetically modified foods, genetically engineered seeds, test tube babies, human clones, and genes of human insulin.
CHRISTIAN APPROACHES TO SELECTED ISSUES
Human cloning
This is a form of genetic engineering. It’s a creation of genetically identical copy of a human being, human cell.
- Twins are a form of natural cloning
- There’s therapeutic cloning and reproductive cloning (human cloning)
- Therapeutic cloning is when cells from an adult are used in creating medicine or for research
- Reproduction cloning is the making of human beings
- More than 90% of cloning has failed.
- Animals cloned have died young, had cancers or arthritis.
- Human cloning is illegal worldwide
- Genetic cells are used to treat Alzheimer, heart attack, cancer
- Test tube babies are different from human cloning. Test tube babies are where the egg and sperm is fused together outside the body.
- In cloning, a needle like device is used to draw out the cells from an embryo, then preserved using chemicals, then put in a womb/uterus to grow. Some do not need a sperm cell, they use other body cells for fertilization.
Reasons for advocating human cloning
- Can clone people whose genetic composition is of a genius, people with special abilities or talents
- Can be able to bring, revive back great extinct characteristics.
- Those who support it believes it can reduce immorality
Reasons against human cloning
- God is the sole creator. Cloning takes the place of God.
- It de –humanizes human beings purpose of human reproduction
- It destroys uniqueness of each individual (Cloning is an exact copy)
- It can be abused and used to create antisocial people (rapists, thieves)
- May create deformed people
- It’s un-ethical, immoral experiment. Its destruction of the embryo hence abortion
- 95% of clones have failed (animal) most animals died
- Its illegal
- Closed animals died of cancer, had arthritis, deformities and an early death
- Cloning may bring a destructive copy of humans
CHRISTIAN APPROACHES TO SELECTED ISSUES
Advantages of genetic engineering
- Implanting genes that are diseases free in people, plant and animals could prevent diseases.
- Genetic crops yield more
- Helps to determine the biological parent in case of dispute on babies (DNA)
- Helps to increase disease resistance in crops and altering animal traits in plants and animals
- Assists in classifying blood during screening before it’s transfused to another person.
Christian view of genetic engineering
- Christians support genetic engineering that is beneficial to human beings e.g. Cure of genetic diseases, production of drugs, plant and animals
- Human beings are made in God’s image and are loved by God with or without defects.
- The dignity of the human being is eroded or disregarded and should be upheld.
- Christians oppose cloning and test tube babies
- Its against God’s will or teaching
Plastic surgery
– It’s to change or mould the shape of something, to enhance or restore an area of the body
– It’s repairing or improving of damaged, diseased or unsatisfactory shaped parts of the body with pieces of skin or bone taken from other parts of the body.
– Skin grafting is the most common type of plastic surgery
– Plastic surgery is done on cleft lips i.e. cosmetic surgery, breast surgery – reduction or enlargement, surgery done to look younger.
Reasons for plastic surgery
– It can help restore ones confidence or self – esteem
– It enhances beauty, attractiveness or youthfulness
– It enhances a person’s life and can be a life changing procedure
– It may help a person to get a new job
Disadvantages
– Its expensive
– Can lead to transmission of diseases
CHRISTIAN APPROACHES TO SELECTED ISSUES
Christian views on plastic surgery
– Some support it, as it has some benefits
– Some Christian oppose plastic surgery in order to look younger
– Some argue that some people do it because of a lack of self – acceptance, low self esteem hence should work on such issues first.
THE CHRISTIAN VIEW ON THE EFFECTS OF MODERN SCIENCE AND TECHNOLOGY ON THE
ENVIRONMENT (POLLUTION, DESERTIFICATION)
In Genesis 1, man was given the responsibility of taking care of the environment
Ways of taking care of the environment
- Cleaning up the environment, clean up rivers
- Educating people on the importance of conservation
- Dispose industrial wastes properly
- Enforce use of environment – friendly fuel (unleaded fuel)
- Factory owners to supply protective wear to factory workers
- Planting of trees and flowers
- Establishing airports, industries, and disco clubs away from residential areas.
- Advocate for laws to be passed to minimize noise from vehicles, aircrafts, entertainment centres.
- Waste to be managed through
Reuse e.g. bottles
Recycle – plastic bottles to be recycled to plastic bins, old newspapers to be recycled to tissue papers.
Recover – burning waste products to produce electricity
Waste can be managed to reduce use of ‘Throw away’ goods e.g. batteries to use of electricity.
CHRISTIAN APPROACHES TO SELECTED ISSUES
POLLUTION AND ITS EFFECTS
It’s introduction into the environment of substances or energy that is liable to cause hazards to humanhealth, harm to living resources and ecological systems
In simple terms pollution is the contamination of the environment.
Substances that cause pollution are called pollutants. Some of the pollutants include;
- Industrial affluent
- Pesticides
- Insecticides
- Fertilizers
- Ultra – violent rays from nuclear plants
- Dust
- Smoke
- Noise
- Waste heat
- Exhaust gases from automobiles
Types of pollution
- Water pollution
- Air pollution
- Land pollution
- Radiation pollution
- Sound pollution (noise)
Water pollution
This is the increase of substances in water in excess of its rightful chemical components thus making it unsuitable for human, animal or plant use.
– Disposing domestic and industrial waste into rivers, lakes, seas etc pollutes water.
– Disposing agricultural chemicals pesticides into water bodies.
– Oil spilling into waters
– Poor sanitation bathing or washing clothes in rivers or dams
Effects of water pollution
- Causes diseases, which are communicable such as cholera, typhoid, and dysentery.
- Leads to death of marine life – birds (Flamingo) fish by oil spills
- Mercury (metal) leads, silver is poisonous. They kill organisms.
- Water becomes unfit for human consumption
Air pollution
– Presence of contaminants in the atmosphere caused by
- Smoke
- Fumes
- Dust – from mines, quarries
– When there is an increased level of carbon dioxide in the atmosphere that’s pollution
– Other major atmospheric pollutants include gases such as chlorofluorocarbons (CFC), and sulphur dioxide (SO2)
– Nitrogen Oxide (NO) i.e. fumes from vehicles, aircrafts, industries
CHRISTIAN APPROACHES TO SELECTED ISSUES
Effects
- Leads to diseases such as bronchitis, asthma
- Leads to depletion of the Ozone layer leading to ultra – violent rays of the sun penetrating to the earth causing skin cancer, cataracts (eye problems), low plant yields.
- Causes rusting of roofs
- Causes acid rains
- Carbon dioxide (02) in the atmosphere has led to global warming.
- Formation of smog (thick fog), which can lead to accidents.
- Colored rain due to large amounts of dust in the atmosphere
- Eyesight loss due to gas leakages from industrial plants.
Land pollution
Land pollution is any physical or chemical alteration to land, which causes change in its use and renders it incapable of beneficial use without treatment.
– Improper or excessive use of insecticides, pesticides makes land acidic
– Land is also polluted by improper disposal of waste / garbage, broken glasses.
Effects
- Waste is an eye sore spoiling the beauty of the environment
- Broken glass can lead to injuries
- Open mining leaves pits, which are a danger to people and animals.
CHRISTIAN APPROACHES TO SELECTED ISSUES
Noise pollution
– Experienced especially in urban centres, near roads, running water, mining areas, airports, music from bars, nightclubs etc.
– An instrument called sound meter measures noise. The lowest unit is O Decitel, which is okay. More than 80 decibels is harmful to the ear.
Noise over 80 decibels can cause (effects)
– Deafness, hearing problems
– Psychological disorders – frustrations, irritation
– Insomnia
– Shock due to sudden noise
– Cracking of walls
Noise can be minimized by
- Construction of sound proof buildings
- Location of residential areas away from industries, airports, bars, main roads
- Banning of unnecessary hooting, playing of loud music in public vehicles
- Installing silencers in generators
- Education people on the effects of noise pollution
CHRISTIAN APPROACHES TO SELECTED ISSUES
Pollution caused by radiation
Mainly in developed countries
Atomic explosions e.g. Hiroshima / Nagasaki in Japan in 1945. The side effects of mutations of born children. Some children born with deformities. The radiation caused chromosome mutations. Some mutations on the cells of the parent / grandparents.
Nuclear power stations also a danger
Medical equipment e.g. X ray machines when one is over exposed to these radiations (x – rays) it can lead to development of cancer.
DESERTIFICATION
This is slow encroachment of desert – like a condition to land that was previously productive making it desolate, uncultivatable and uninhabitable. Human activity accelerates creation of deserts.
Causes of deserts
- Natural
- a) Persistent rains in a semi – arid area
- b) Exposure of an area to very high, very cold temperatures
- c) Inadequate rainfall for a long period of time
Human
Human activities that lead to desertification are
- Cutting down of trees (deforestation) for land use such as building, industries, and not replacing them.
- Use of water from wells to irrigate land. Its harmful especially salty water – salt on soil salination is toxic to soils.
- Incorrect use of pesticides and fertilizers destroy soil nutrients.
- Industrialization – industries emit carbon dioxide (CO2) leading to formation of acid rain, which leads to unproductive land hence desertification
- Overgrazing especially among the pastoralist communities
- Poor farming methods like cultivation on riverbanks and slopes, which causes soil erosion, leading to desertification.
SOLUTIONS TO DESERTIFICATION
Land can be restored through the following ways;
- Removal of people, livestock from certain areas e.g. forests
- Installation of good drainage systems
- Reduction of water logging / salination
- Use of alternative sources of fuel such as wind, solar, biogas instead of cutting down trees to use as fuel (charcoal)
- Advocate for penalties to those who pollute the environment – factories
- Replace trees that are cut down
- Build water storage facilities to store rain water then use it for irrigation
- Educate people on the importance of the environment
- Use of manure instead of harmful fertilizers
Emulate Prof. Wangari Maathai implanting trees – 8th October 2004 she was awarded the Nobel peaceprize, an international award, for her efforts in preserving the environment.
