| p>To one who has seen the adverse effects of | | | | science. This has led to conservation of resources |
| some technologies on the environment the | | | | for example purifying sewerage into clean and |
| question how does technology protect the | | | | safe drinking water and the recycling of polythene |
| environment? May have only one answer - it | | | | into usable plastics. |
| doesn't! The reality however is that from the | | | | Use of simple equipment such as garbage cans |
| onset science and technology has been at the | | | | for disposing litter and recycling of natural waste |
| forefront of ensuring the environment is | | | | for instance using vegetable waste as manure |
| safeguarded. Science is a weapon through which | | | | may seem inconsequential but in the long term |
| good or evil can be done depending on the | | | | the benefits are left for all to see. |
| consciences of those who are using it. There are | | | | Machines that in the past used to release a lot of |
| lot of ways in which technology has been used to | | | | toxic fumes into the atmosphere like cars, |
| restore the integrity of the environment. | | | | manufacturing plants and factories and mining |
| From reversing the damage done by the | | | | apparatus have nowadays been modified to use |
| chlorofluorocarbons (c.f.c's) on the ozone layer to | | | | fuel that does not release harmful gases in the |
| minimizing the harmful effects of the greenhouse | | | | atmosphere. Through the discovery of better |
| gases which bring about global warming science | | | | ways of making fuel like from use of sugar cane |
| has played a key role in safeguarding the | | | | processing the harmful effects of polluting gases |
| environment. Through science machines that were | | | | have been greatly reduced. Use of more efficient |
| discovered to be releasing c.f.c's into the | | | | energy systems and means of disposal is how |
| atmosphere were removed from the market and | | | | technology protects the environment. Continued |
| in there place others were invented a case in | | | | scientific research and study into the |
| point the refrigerators of old and modern | | | | environmental hazards that abound keeps on |
| refrigerators that are CFC free. Through scientific | | | | creating awareness about what is right and |
| research it has been discovered that presence of | | | | wrong, what should be avoided or done more all |
| trees and vegetation greatly decrease the | | | | in the interest of protecting the environment. |
| amount of greenhouse gases like carbon dioxide | | | | The use of solar panels to harness the sun's |
| by absorbing them to use in their natural | | | | energy, application of thermal and wind energy |
| processes such as photosynthesis which has led | | | | has provided the necessary incentive and |
| to more environmental awareness | | | | alternative to the over use of oil and petroleum |
| Advancements in the scientific process of | | | | as the primary source of fuel which has led to |
| wastage disposal have led to the discovery and | | | | better use of natural resources and the reduction |
| adoption of new and better ways for carrying out | | | | of air pollution from toxic fumes. From these few |
| refuse and sewerage disposal. Recycling has | | | | elaborate examples its clear how science and |
| today become a major activity the world over | | | | technology is protecting the environment. |
| which has been through the intervention of | | | | |
