The insights from the UN Environment Programme's "Making Peace with Nature" underscore the intricate interplay between human development, environmental transformation, and economic dynamics. The shift towards the Anthropocene, characterized by significant alterations to the Earth's systems, is driven by both indirect factors rooted in societal ideals and governance, and direct activities impacting the environment. Population expansion, economic shifts, and technological developments emerge as pivotal forces shaping this transformation. Notably, the projected population growth, particularly in Sub-Saharan Africa and South Asia, brings forth challenges and opportunities for the world economy. As urbanization accelerates, predominantly in developing nations, the strain on resources and the environment intensifies.
While wealthier nations consume more per person, emerging economies' aggregate consumption is increasing due to their rising populations. Throughout this decade, we've seen how the bulk of environmental harm is generated by a relatively small proportion of the Earth's population's actions. However, indirect factors are not static; they can and will change in accordance with forecasts for our species' population expansion over the next few decades, and they can be impacted or reduced by various courses of social and economic development. Population growth, for example, has more than doubled in the previous 50 years, and while the pace of increase is predicted to drop, the absolute number will continue to rise.
According to projections, we will have between 8.5 billion and 10 billion people by 2050. However, it is where the population will increase the fastest that is most important. Sub-Saharan Africa and South Asia will witness considerable development, owing to factors such as gender disparities in education and reproductive rights. According to the UN's Shared Socio-economic Pathways (SSPs) illustrated in this report (see figure below), if we achieve global targets such as universal secondary education and contraception access, the population could potentially stabilize or even decrease, which would be better for the environment but could introduce other societal challenges. Another issue of relevance is the issue of urbanization.
Cities are expanding in size and population; according to the research, the majority of expected urban expansion will occur in developing nations. Despite hosting more than half of the world's population, cities produce around 75% of CO2 emissions from energy use. (EP Report pg. 56) Cities frequently encroach on fertile areas, and while cities may not directly impact biodiversity as much as agriculture, their influence on consumption does. However, urban environments may stimulate economic growth and, if effectively planned and managed, can lead to more efficient resource utilization and drive innovation.
Developing nations are now the most vulnerable to the environmental destruction produced by immoral human actions such as oil drilling and the usage of fossil fuels. Developing nations rely more on the Earth's climate and the health of its geographical environment, and urbanization might potentially lessen their susceptibility by providing streams of money from more contemporary means of engaging in the global economy. The expansion of urban areas may help certain regions gain increased global visibility and, hopefully, amplify their voice on a global scale, allowing them to participate in and contribute to the global climate conversation by proposing solutions that directly benefit their population. In essence, the decisions we make now, both individually and as a group in areas such as government, education, and urban planning will have a significant impact on the future of our environment.
