"Humans, The Destroyers of Nature"
Edna S. Carlos
Good Environment is a pre-requisite for the survival of life on Earth. There are visible signs that it is getting degraded. Still, there are no visible changes in our lifestyles to stop the condition getting worse then what it is now. Things that are doing harm to the environment such as working in industries or factories, commuting via fuel-driven vehicles, using air conditioners, etc. have become an essential part of our lives. The amount of energy that we are using is essential and there is no other alternative to it.
The major cause for this is the increased level of CO2, and that is because of the increased rate of burning of fossil fuels. Current measurements of CO2levels have exceeded above 400 ppm breaking every record dating back 400,000 years. And this has led to increase in earth's temperature, which leads to melting of glaciers and increase in ocean level to rise.
Human's digestive tract is a long one like that of herbivores. But still most of the human population relies on non-vegetarian diet. To grow a hen of 1 kilo, many kilos of wheat is required, but 1 kilo of wheat can satisfy the hunger of 2 persons. Hence, this non-veg diet is really expensive to the environment.
Deforestation is required for creating land space for making roads and homes for humans. This leads to destruction of the habitat of wild animals and birds. It also leads to constant increase of level of CO2. Since there are no trees to absorb this gas so it remains in the atmosphere leading to global warming.
Here are some facts, which show on the benefits of Science and Technology progress:
Goods and devices people use in their daily deeds, such us electric light, refrigerator, electric oven, microwave etc. - all which is given to us by science.
Science and Technology has also affected greatly our means of transportation, by making it easy to travel from one place to another quickly. All buses, ships, aero-planes use the benefits of new advancements.
In conclusion, it must be admitted that science and technologies can lead human civilization to perfection in living. At the same time, everything should be done in wise perspectives and to some extents, not to harm and destroy the world. Earth has sound for those, who listen.
