Causes and Impacts of the Global Environment

The term global environment refers to the environmental factors that affect the entire planet, including local, regional, and national environments. Issues of global importance are those that are beyond the control of any single nation, community, or region. Examples of global issues include climate change, water quality, and air pollution. To understand the causes and impacts of global environmental issues, read the following articles:

Climate change

The health impacts of climate change depend on how vulnerable a population is to the current rate of change and how rapidly they adapt. In addition to the level of vulnerability, adaptation efforts must also consider the pace and extent of climate change. A transformational effort to curb emissions is necessary to avoid dangerous temperature thresholds and possible irreversible tipping points. Climate change will affect the health of millions of people. Adaptation efforts must be swift and comprehensive.

The current pledges from governments to limit the growth of greenhouse gases are insufficient to prevent the world from reaching unaffordable levels. By 2100, the average global temperature is likely to rise by nearly a century. In addition, the average sea level rise is projected to rise between twenty-four and sixty-three centimeters. In addition, many aspects of climate change will continue even if emissions are curbed.

Pollution

As humankind’s management of the Earth’s natural systems continues to worsen, pollution is a growing concern. Climate change, for example, is causing the rise of tropospheric ozone, which is the major constituent of smog and contributes to cardiovascular disease. Increased atmospheric carbon dioxide levels are also increasing pollen production and contributing to air pollution. Additionally, man-made pollutants are threatening drinking water sources and obscuring the sun.

Some countries have made strides to reduce global pollution. Recycling has helped reduce the amount of waste sent to landfills, incinerators, and waterways. In fact, many European countries and some North American countries recycle 50 to 60 percent of their garbage, compared to only 30 percent in the United States. Other government actions are aimed at reducing pollution. For example, governments can limit the types of chemicals used in industries, such as agriculture, and enact regulations to filter coal-burning power plants’ smoke. Additionally, governments can fine individuals and businesses who illegally dump pollutants.

Water quality

This publication provides a concise snapshot of the most pressing issues in global water quality and the link to internationally agreed goals. While there is some evidence that water quality is improving in some regions, others still have serious issues to address in order to ensure universal health. The report details the approach taken to develop the global water quality index, including the preliminary sensitivity analysis and validation against real water quality data. It then discusses the limitations and next steps.

The most common water pollution problem is eutrophication, a condition in which pollutants from land are dissolved in the water, causing a reduction in its overall quality and availability for human use. This problem is exacerbated by non-point sources such as fertilizer application and animal farming. High sediment loads, heavy metals, and organic pollutants accumulated in rivers and lakes are also among the biggest sources of land-based pollutants. These pollutants ultimately enter the oceans, causing severe water pollution.

Food and energy needs

As the world’s population grows, so does the demand for energy, food, and clean water. Innovative ideas are needed to meet these needs while minimizing the adverse impacts on the environment. Global food security and zero hunger is at risk, and innovative solutions must be developed to provide food security for all. WFP implements market-based and sustainable energy approaches to enhance food and energy supplies and improve resilience activities. This paper examines some of the key challenges and solutions in the areas of food and energy.

The consumption of protein per capita in the world exceeds the amount necessary for healthy living in every region, except for the Americas, where it is the lowest. Imports of protein, a key energy source, exceed the total food energy requirements of every region except the Americas, with protein imports being highest in North Africa, West & Central Asia, and Industrialised Asia. In the global context, protein imports account for almost 90% of total food energy. However, exports account for a relatively small proportion of total protein, with most of it being destined for biofuel production.

Indigenous values

In the twenty-first century, indigenous peoples are standing at the crossroads of globalization, challenging the assumptions that are driving the modern world. They reject the consumer culture that has dominated the world’s economy for the last 500 years. Consumer societies prosper and grow at the expense of other people and the environment. Yet, despite efforts to address this issue, the United Nations Conference on Environment and Development (UNCED) has failed to come to any agreement. This is despite the fact that wealth transfer would require higher prices for rich countries and a reduction in consumption by poorer nations.

A more balanced approach would involve conducting primary research in regions that are underrepresented in mainstream academia. Future studies could also look at bibliometric analysis and evaluation of existing adaptation policies to identify biases in the literature. Likewise, future primary research should engage in the decolonization agenda rather than taking an extractive approach to knowledge generation. In this way, future studies could contribute to the development of global environmental policy, while respecting Indigenous values in a global environment.

Conflicts between countries over environmental issues

Environmental governance and conflict can be incompatible. Regardless of the motivations, environmental damage can hamper progress on many issues. Massive urban rebuilding efforts often require massive volumes of resources. Conflicts over environmental issues also create opportunities for building peace, sustaining peace, and transforming societies. The following are four reasons why environmental governance and conflict may not be compatible. Let’s explore these issues in more detail. After all, the environment is an integral part of human well-being.

Natural resources are global and must be managed across borders. When coordination is insufficient, inequitable, or if resources are deliberately diverted from their intended uses, international disputes can occur. Population pressures, loss of livelihood, and migration patterns also exacerbate environmental vulnerabilities, which may lead to violent conflict. In such situations, global environmental governance is essential to protect the environment. However, the impact of environmental conflicts may be detrimental to human well-being and the environment.
