As per many articles on the internet “Sustainability is the capacity to endure, it has become a wide-ranging term that can be applied to almost every facet of life on Earth.” I chose this topic because it is starting to become a rising issue in our society as we are facing the problem of global warming and climatic changes now a days Sustainability is also a more sufficient topic from which I can easily relate to and gain more knowledge in it with full interest.
Pollution is a threat to our world as it would greatly affect our global development. Many cases of hazardous pollution have been resolved, like lead has been banned from car fuels. Toxic wastes are treated with greater care, industrial safety has significantly increased, electric power plants have become cleaner, and energy and materials are used more efficiently. The presence of a dangerously harmful or poisonous substance or any form of energy (such as radioactivity) to the environment at a rate faster than it can be dispersed, recycled, or stored in some harmless form is called pollution.
Most of the pollutions are accounted for as land pollution, water pollution and air pollution. There are many types of pollution that harm the environment but in my opinion air pollution is the most major. As the air we breathe in starts to be polluted, the risk of harmful diseases like chronic heart problems, asthma and lung cancer increases. Pollution now largely affects our environment and is one of the biggest reasons for the increase of death rates in the urban countries.
“It is crucial for the city and national governments to make urban air quality a health and development priority”, says WHO Dr. Carlos Dora.
In Pakistan the biggest reason for air pollution is the emission of toxic gasses from the exhaust fumes. Pakistan does not have catalytic convertors like the other countries that help to absorb the harmful gasses to reduce rate of pollution and thus the environment stays clean and people have higher life expectancy. There are many industries in the most developed cities of Pakistan like Karachi and Lahore than give out harmful pollutants such as sulfur dioxide and carbon monoxide. The governmental authorities appointed to control these matters don’t take much consideration of these factors. As a result these cities face the problem of thick smog that increases the death rate per year. All these negligence have led to the birth of many respiratory diseases and the extinction of many precious animal species. Even Islamabad, which is the capital city, is not safe from the deadly smog. To reduce pollution we need to make sustainable reforms that encourage the factory owners for the use of catalytic convertors. Global warming is a great problem nowadays as it’s causing severe hot weather conditions all around the world; it is generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants. Global warming is a phenomenon of climate change characterized by a general increase in average temperatures of the Earth, which modifies the weather balances and ecosystems for a long time.
The average temperature of the planet has increased by 0.8º Celsius (33.4° Fahrenheit) compared to the end of the 19th century. Each of the last three decades has been warmer than all previous decades since the beginning of the statistical surveys in 1850. If no action is taken then it would badly affect the humanity and the biosphere. Global warming has become a rising issue now and we are biggest reason for its cause. The extensive use of fossil fuels in our lives is the major source of global warming, through which the greenhouse gases are emitted. The exploitation of forests for better roads and buildings is also an important reason as the amount of Carbon dioxide in the environment will increase when there will be no trees available. Farmers use fertilizers so that crop could grow quickly but it is harmful. In Pakistan 75 percent of crop farming is growing under the use of fertilizers. Poor waste management systems led to emit greenhouse gasses such as methane and chlorofluorocarbons which are released to the atmosphere. Modern life is highly dependent on the mining sector.
Finally, overconsumption also plays a major role in climate change. Recently Pakistan’s Prime minister Imran Khan has taken this issue into consideration and has started a ‘save the trees program. The estimated number of climate refugees by 2050 is 250 million people, as due to global warming the temperature is increasing at a drastic range. Glaciers will start to melt and severe draughts will cause more water shortages. Disruption of habitats will cause many plant and animal species to become extinct. Infectious diseases like asthma will start to spread more as well as the allergies because the climatic conditions will become more favorable for pathogens and mosquitos. The issue of global warming is increasing day by day. Because of global warming and greenhouse gasses, the ozone layer is danger. Carbon dioxide is also increasing in the atmosphere. Renewable energies, the first way to prevent climate change is to move away from fossil fuels. Renewable energies like solar, wind, biomass and geothermal energy are very helpful and free of cost. Producing clean energy is essential, but reducing our consumption of energy and water by using more efficient devices (e.g. LED light bulbs) is less costly and equally important .Promoting public transportation, carpooling, but also electric and hydrogen mobility, can definitely help reduce CO2 emissions and thus fight global warming. CO2 emission can be prevented from buildings by constructing new buildings and renovating the old ones. The use of natural resources is preventive massive deforestation in many areas. Adopting responsible consumption habits is crucial. Global warming is causing many valuable species to die. Last but not least, recycling is an absolute necessity for dealing with waste.
