During the Industrial Revolution, the fossil fuel powered industry produced thick clouds of black smoke. This threatened the lives of the white moths that would rest on walls and tree barks as they became clearly visible to birds preying on them. Now that the white walls were turning black because of thick smoke, the white moths became easy to identify as they rested on the darkening walls.
Suddenly, there was a rise of a new breed of black moths. Some people believe these black moths to be a result of white moths being coloured by the black smoke from the industry. However, scientists attribute this colour change to a gene mutation caused by the smoke.
In a similar development, wheat farmers in Southern Africa usually have hard times in dealing with the quelea birds that continue to terrorise them year after year. Most of these farmers are using toxic substances to spray and kill these quelea birds. However, not all birds are killed in this exercise. Some birds survive and are severely affected by the chemicals, which is most likely to cause an intense gene mutation in the near future.
This does not only harm these quelea birds, but also other creatures that feed on these birds. Also, the quality of air and soil maybe affected by the successive seasons of spraying these chemicals.
Trent Engineering has therefore devised a new method of dealing with this problem without threatening the lives of the birds and animals that feed on them. The method is less costly to implement and does not leave any negative effects on the environment and the ecosystem.
