While we are at the topic of being environment friendly, there is also scope for those who have creative ideas about how to move away from the current destructive business habits to more durable and earth friendly means. The renewable energy is also cheaper as compared to traditional oil and gas, and when it comes to India and Pakistan, there is a lot of support from both the government and the public for moving towards environment friendly business procedures. However, not everything that appears environment friendly is indeed so. There are actual incidences in Karachi where millions of trees were planted to improve the air quality, however they sucked all the water from the ground and worsened both air and water quality. Therefore, the job of consultants is as important as engineers. It is worthy of all the hard work that goes into it, and not just in terms of helping humanity.
