How Construction and the Built Environment can Both Benefit and Harm the Natural Environment

Since it's earliest days, the Human Race has sought to bend the natural environment to it's will; since the first Man (or woman!) cut the first branch from a tree, a battle has been fought between mankind and Mother Nature. Rivers have been dammed, forests cleared away and mountains levelled in our quest to mould the environment to our needs. Our blinkered onslaught against the planet reached a terrible peak in the middle of the last century. Since then we have begun to realise the damage that has been done in the name of progress and civilization, alas too late. Countless species of flora and fauna have …show more content…

This excess of greenhouse gases in our atmosphere is due to the world's growing population burning more fossil fuels, such as coal, oil and natural gas for energy, as well as expanding agriculture and increasing deforestation.

The Industrial Revolution. Around 200 years ago, the Industrial Revolution ushered in an era in which humans rely on fossil fuels to run the many machines used in industry and everyday life. The burning of fossil fuels releases carbon dioxide into the atmosphere. Since the Industrial Revolution there has been a steady increase in the production of carbon dioxide, and an increase in global population. Some of the carbon dioxide is absorbed by trees and plants or dissolved into the oceans; these are known as carbon sinks. Unfortunately, human activities have been producing carbon dioxide faster than it can be absorbed naturally, while widespread forest clearance has reduced the carbon sinks.

Scientists have been measuring the amount of carbon dioxide in the atmosphere for about 40 years, over which time the concentration has risen by about 15%. Older records of carbon dioxide, obtained from air bubbles trapped in Antarctic ice go back 300,000 years. Scientists have found that carbon dioxide levels now are 32% higher than before the Industrial Revolution, higher than they
