I wanted the time machine to convey me to the 25th century. At that moment, I was curious about the changes that the world would experience in the impending years. However, as I stepped out of the time machine, I was introduced to a horrible sight. The place seemed dry and brown. For an instance, I presumed that the machine had transmitted me to the Sahara desert. The chlorophyll was gone astray in the plants. The place was dominantly occupied by a throng of industries.
I could spot the people carrying an oxygen cylinder as oxygen gas was scarce in the atmosphere and carbon dioxide, nitrous oxide, and methane dominated its composition. I got hold of a newspaper. The words that were used extensively were heat stress, ecological disturbances, air pollution, coastal flooding, sea level rise and global warming. I could make out that there was a lot of disturbance in the environment-which was indeed a result of unchecked human activities. The greenhouse effect had raised sea level from 9 to 12 feet and various islands had sunken. Animals were getting endangered due to Ocean acidification and natives of our country had started to migrate to the poles where the climate was cooler and suitable.
Without wasting a time, I reverted to the present world. I delineated the 25th century to the people and reminded them of the killer heat waves, devastating droughts, and fiercer storms that could be witnessed in the future. We executed awareness programs and encouraged people to save energy; plant trees and recycle possessions rather than altering our environment through industrial practices. Human activities have a serious effect on the environment. We need to preserve the environment, not violate it.
