Good morning everyone, today, the topic of my speech is a very relevant one – climate change. Due to large scale industrialization in the last century there has been rapid changes in the climatic conditions too. These climatic changes have a horrendous impact on the life on earth.
Optimum climatic conditions are what makes Earth a unique and only planet capable of sustaining life. Climate is directly related to the food we eat which is fuel for life. Crops cannot grow in a changed environment and weather pattern which results ultimately into famines and other natural calamities that deprives us of the normal supply of food.
An advent of industrialization has led to the setting up of several factories which emit harmful toxic gases into the atmosphere. these gases usually are oxides of Nitrogen and Sulphur. This then combines with the atmospheric moisture and falls down as rain. This rain when comes in contact with crops cause heavy damage resulting in lower yield and thus causing a reduction in food supplies.
Also due to industrial activities like indiscriminate mining, oil drilling, etc., the tectonic plates in the earth surface gets disturbed and as a result several landslides as well as earthquakes have taken place in the recent past. The shifting of the tectonic plates is a result of human activities under the earth.
Stretched of rocks are often bombarded with dynamite to dig up precious metals or to produce raw materials for construction. These disturbances in the rocks sends shockwaves below the surface which amount to tremendous tectonic shifts and earthquakes. Climate change has also caused several disasters like Hurricanes and tsunamis.
Because of the harmful gases released into the atmosphere from the factories, the level of pollutants in the atmosphere increases. These pollutants interact with the Ozone layer of the atmosphere and destroy it. The Ozone Layer is a layer of protective Shield around the earth protecting us from harmful space objects and rays.
When there is a hole in the ozone layer, the sun rays as well as various other harmful electromagnetic radiation can enter the atmosphere increasing the temperature of the earth causing climate change in the long run. Climate change has resulted in an increase in the overall temperature of the earth.
This increase in temperature has caused the polar ice caps to melt. And as a result of the melting of these ice caps the water level in the water bodies of the world have risen considerably. If the temperature of the earth continues to rise at the present rate then the glaciers in the southern and northern polls will melt and the water from them would go into the water bodies causing the overall water level of the world to rise so much that floods might occur in the entire world.
Another problem that might occur because of climate change is an increase in diseases. Pests, insects, and various other germs and pathogens multiply rapidly in a warm weather. As the global temperature rises, the number of these pathogens also rises and consequently, the occurrence of pathogenic diseases also increases.
Climate change is an extremely important issue in today’s world. Several organizations are working tirelessly towards finding solutions to stop or reverse the adverse climate change. Because of excessive change in the composition of water bodies, the ocean currents have also changed.
Because of excessive mixing of seawater with river water, water current disturbances have caused flash floods in many areas. Because of these floods, the fauna of an area gets badly disturbed. Not only this, it also causes large scale damages to life and property.
Irrigation patterns audio need to be changed in accordance to floods and draughts. However, because of climate change, there is a high uncertainty of floods or droughts which leads to change in cultivation patterns. The farmers fear losses and ultimately end up investing less into the crop thus producing a lesser yield.
The world is our dwelling place and it is our sole responsibility to take care of it. However in the rat race for industrialization and modernization we have neglected care for the planet. It is this unique planet that has given us life and now we have started to take it for granted.
Whenever we take anything in life for granted, it is usually the beginning of problems. Similarly, nature too can answer us in harsh manner if we go too far in exploiting it. Scientists have suggested that the nature had a threshold of its own and beyond that, it will start to respond with natural calamities like earthquakes, tsunamis, etc.
These should be taken as warning signs and steps must be taken to stop pollution or else, we will have to see such an apocalypse that we wouldn’t be left alive even to repent about our misdeeds.
