Global Climate Change

Global climate disruption has become one of the major threats to our planet’s ecosystem. The utilization of fossil fuels by humans generates greenhouse gases in the environment. Coal, gas, oil, and other fuels emit carbon dioxide, nitrous oxide, methane, and other gases that absorb warm air inside the earth like a greenhouse. People all over the world are addressing the issue by endeavouring to reduce their carbon footprint. But carbon footprint calculation will not suffice if we cannot control the growth of the human population.

Population growth and its effects on climate change

According to an estimate, during the 20th Century, the human population raised from 1.6 billion people to 6.1 billion people. Greenhouse gas emissions increased 12-fold during these 100 years. It is assumed that the global population will exceed just in the next 50 years, which will result in global warming or excessive heat on the planet. Every day about 220,000 human babies are taking birth. Each of them will leave their carbon footprint on the atmosphere of the earth. If the population increases, demand for residence, vehicles, and food will increase simultaneously.

It is noticed that the world’s food production system has contributed almost 30% emission of the leading greenhouse gases. The utilitarian lifestyle of today’s world aims to maximize the wellbeing of people, and it completely relies on fossil fuels. More population means more need for fossil fuels. Fossil fuels, particularly oil, are needed to run vehicles, manufacture pesticides, fertilizers, and other appliances. A growing population will increase the causes of global warming to a great extent. Usage of non-biodegradable products like plastics has increased a lot which is another great threat to the environment.

Impacts of climate change in developed and developing nations

In the present day world, developed nations like the United States of America, Germany, Japan contribute to the major share of global warming. These countries are less populated than the developing countries, but their consumption of fossil fuels is more than developing countries like India and China. It is expected that by 2050 these countries will cause more than half of the global greenhouse gas emissions.

On the other hand, in most developed countries, population growth has started dropping, which is considered a great sign. But as of now, most undeveloped and developing countries are unable to control their population rate. All efforts made by the developed nations to limit CO2 emissions will go in vain just because of the overpopulation in the developing countries. Thus, it is proved that population and the causes of global warming are inseparably connected.

Here we should not forget another major cause of global warming that is deforestation. No one can deny the role trees play in saving our environment. But as a result of population growth, forests are being ruined at an alarming rate. This makes a negative impact on the biodiversity of the planet. We often forget that everything is interlinked in the cosmos. If there is no tree, there will be no rain.

Climate will change, and the earth will become a barren land. If we observe the climate change facts, we will notice that the planet has already started showing signs of climate change and global warming. Recently a Siberian town has experienced its hottest-ever temperature, which is more than 100 degrees Fahrenheit.

Animal migration is another important indicator of global climate change. Insects, birds, and animals are compelled to change their habitats. As a result of the annihilation of forests, forest animals are entering into human localities. Many species are facing the threat of extinction. Here we can mention what Worldwatch Institute commented about this problem. According to them, “if we cannot stabilize climate and we cannot stabilize population, there is not an ecosystem on Earth that we can save.” So, to save the environment, minimization of the population is seriously needed.

What we can do to prevent climate change

We all know that climate change is wreaking havoc on the ecosystem of our planet. Now we should concentrate on the steps that we can take to deal with the climate crisis. A study report published by the Universities of Lund and British Columbia claims that having fewer children is the ‘single most effective measure’ that every individual should take to reduce global warming. But unfortunately, many people around the world are deprived of minimum education. They have no idea about the negative impacts of overpopulation.

They are unable to make a proper family plan. The Government of all nations must take action to stop child marriage. Employment and women’s empowerment can play a vital role here. Non-Governmental organizations should come forward to educate women in rural and slum areas. Often in economically deprived areas, people tend to give birth to more children to increase the number of earning family members. Child mortality is also another significant cause of having more children. Government should take care of the health of the citizens to decrease the infant mortality rate.

All these actions will definitely help slow down population growth and bring down the effect of human-caused climate change to sustainable marks.
