How Earth’s Population Affects Global Warming
Earth’s population grows rapidly consuming bigger amounts of natural resources and taking more and more wildlands to satisfy its needs. In the past, people lived their lives in harmony with nature and the environment but now our consumption habits and way of living require more resources for each person than ever. The most serious problem caused by population growth is Global Warming.
There are many ways of how population growth affects the environment. Modern humans need a lot of things and spend a lot more natural resources than their ancestors did. Many peoples have cars, houses, use disposable plastic items and their existence implies the usage and wastage of big amounts of irreplaceable natural resources such as water, oil, fossil fuels, and ores.
When we go out we use fossil-fueled transport, our deliveries come to us from overseas and even regular T-shirts leaves a long and big carbon footprint because our clothing and most of the everyday items are made in distant countries and continents. Our nutrition habits have an even bigger carbon footprint than our cars and clothing have.
Industrial pollution of the Environment
The production of meat, poultry, dairy, and eggs requires unimaginable amounts of natural resources such as water, soil, and crops. Farm animals consume a lot of water and fodders during their lives and produce big volumes of biological waste and greenhouse gases.
Transportation, nutrition, clothing, packaging, entertainment – all these life spheres affect very badly on the environment. Not because they’re bad but only because of our way of living and linear economy that is aimed at the mass production of affordable but low-quality goods. As a result, we have global environmental contamination and slow, but yet hardly-reversible climate change which is called Global Warming.
Many people deny Global Warming as an unproven and falsified pseudo-scientific belief. Some people reject to believe that humanity and their way of living are the root cause of the current environmental crisis, some believe that it’s just a natural process, expected and irrevocable. The negative effects of population growth had nudged many scientists to seek how our activity affects the planet.
Researches prove that Global Warming is a real danger
Numerous scientific studies and researches prove that Global Warming is real and happens a hundred times faster than it should have been. Also, they prove the relationship between increased Earth’s population and climate change.
We all have heard about Ice Ages and the constant increase of the Earth’s temperature and such processes seem natural to us. Our planet heats up continuously, but thanks to human activity, it heats up much faster than it should have been. Naturally, the Earth’s heating takes thousands of tears until the climate would change and glaciers would melt, but due to human activity and fastened industrialization, it had happened within several decades.
Most environmental changes are irreversible and considering the results of numerous scientific studies and scientists’ warnings, humanity is nearing the point of no return.
Global Warming manifests itself by many negative testimonies. Overpopulation’s impact on the environment could be seen in glaciers melting, extinction of species, planet’s heating, natural catastrophes, and others. All these factors affect humanity in the worst way that is possible because humans are only a part of the Earth’s ecosystem.
For example, extensive usage of agricultural lands and pesticides has reduced bee populations which affects the fertility and productivity of crops and food cultures. If bees are extinct (and it is quite possible) more than half of the food drops will die causing global hunger and the death of millions of people.
Raising the ocean level
Glaciers melting desalinate the oceans and raise the ocean level, flooding and spoiling big areas of land. Oceans desalination threatens the very existence of phytoplankton. These tiny organisms produce more than half of the world’s oxygen and their entire population could be wiped out in a few years if the ocean’s temperature or biological conditions won’t suit them enough.
Plus deforestation heats the planet up and reduces the oxygenation level of the atmosphere while the usage of agricultural lands displaces habitat species and all wild animals around. In a short time, such common and familiar animal species such as hamsters, deer, salmon, tuna, cod, and many others could disappear.
Humanity’s activity and economy model leave no place for wild nature and a healthy environment. A growing population will demand more and more and there’s no chance that all Earth’s population will realize at the same time that radical measures should be immediately taken to prevent further destruction and fatal consequences of Global Warming. But humanity must reconsider its way of living to save what’s left of our world.
The Paris Agreement is one of a few international projects that is aimed at the reduction of CO2 emissions by 2050. Since Earth’s population fastens Global Warming by the extensive usage of fossil-fueled transport both for personal and society’s goals, global transition to eco-friendly and carbon-neutral transport will benefit our planet a lot.
Nutrition habits are another problem
Animal farming breeds cows, pigs, chickens in huge numbers, spending irrational amounts of natural resources, and fossil fuels. Animal farms take vast areas of wildlands, animals produce big volumes of biological waste that emits greenhouse gases and CO2, no fewer amounts of fuel is used to transport meat, animals, and fodders to destination points and export the final product. Also, animals consume a lot of plant fodders. The land that is used for fodder cropping could have been used for cropping and food culture cultivation.
Effects of population growth show that the existing economic model is unsuitable for our world. Effects of climate change threaten humanity and all living species on this planet. Long-term environmental changes will change our world beyond recognition even if we will concentrate all our energy on the prevention of Global Warming and its related processes. Our population and environment are intended to live in harmony and peace and now it has become a matter of survival.
