Environmental Challenges We Are Facing Today

The Earth is currently grappling with a wide array of environmental challenges that have far-reaching impacts on society, the economy, and the environment itself. While a handful of these challenges stem from natural occurrences, the vast majority result from human activities. These activities, known as anthropogenic processes, involve exploiting and modifying the natural world to meet human needs and desires.

Climate Change

The most significant environmental issue we face today is climate change. The United Nations describes it as long-term alterations in temperature and weather patterns, which can occur naturally due to solar variations or significant volcanic eruptions. However, human actions have predominantly fueled climate change since the 1800s, mainly by burning fossil fuels such as coal, oil, and gas.

These fossil fuels release greenhouse gases into the atmosphere, functioning like a blanket that holds the sun’s warmth close to Earth, leading to increased global temperatures. The most significant contributors to greenhouse gas emissions include carbon dioxide and methane. These gases are emitted through activities like driving cars, heating buildings with coal, deforestation, agricultural practices, and oil and gas industry operations. The main sectors responsible for these emissions encompass energy production, industrial processes, transportation, construction, farming, and land management.

The latest Intergovernmental Panel on Climate Change (IPCC) Report indicates that human-caused greenhouse gas emissions have led to roughly 1.1°C warming since 1850-1900. Furthermore, it projects that, on average, global temperatures are likely to rise to or surpass 1.5°C of warming within the next two decades.

Yet, the impact of climate change extends beyond just a rise in global temperatures. Given the interconnectedness of Earth’s systems, alterations in one aspect can also influence others. Thus, climate change also causes:

  • Increase in frequency and severity of droughts and heat waves.
  • More intense storms and higher precipitation rates.
  • Prolongation and exacerbation of wildfire seasons.
  • Rising sea levels due to melting ice caps and glaciers.
  • Escalating challenges related to water scarcity.
  • Significant decline in biodiversity as species struggle to adapt.

Beyond its environmental implications, climate change also places societies in increasingly vulnerable situations. Communities across the globe are facing heightened risks and challenges due to the unpredictable and often severe changes in climate patterns, from diminishing food security as crop yields fluctuate and water sources become less reliable to the exacerbation of health issues due to heatwaves and the spread of climate-sensitive diseases. Climate-induced natural disasters and resource scarcity also lead to displacement, economic instability, and social strife.

What You Can Do to Help

Stabilizing the rise in global temperature and minimizing climate change’s impact requires substantial, swift, and enduring reductions in greenhouse gas emissions. Successfully achieving this goal depends on a collective effort. However, your individual contributions are incredibly vital. Each action you take to diminish your carbon footprint can help steer us towards a more sustainable future. Here’s how you can do it: 

Reduce energy consumption

Generating electricity and heating involves burning fossil fuels, which significantly contributes to producing greenhouse gases (GHGs). According to the US Energy Information Administration (EIA),  the combustion of fossil fuels was responsible for a substantial portion of GHG emissions in the USA—73% of the total GHG emissions and 92% of total U.S. anthropogenic (human-caused) CO2 emissions in 2021. This highlights the crucial role that energy production and consumption play in the broader context of climate change. 

Simple habits such as switching off lights in unoccupied rooms and unplugging electronic devices that aren’t in use can significantly lower your energy use. These small changes help cut down on electricity demand, reducing the need for energy production and associated emissions.

Choose Energy-Efficient Appliances and Vehicles

Investing in appliances with high energy efficiency ratings and opting for low-emission vehicles or electric cars can make a considerable difference in your carbon footprint. Energy-efficient products consume less power and are a step towards a greener lifestyle, while eco-friendly vehicles reduce the release of harmful gases into the atmosphere.

Support Renewable Energy Resources

By advocating for and investing in renewable energy, you contribute to decreasing reliance on fossil fuels. Solar panels and wind turbines provide clean, sustainable power alternatives that don’t emit greenhouse gases, making them pivotal in combating climate change.

Reduce Meat Consumption and Opt for Plant-Based Alternatives

The livestock sector is a significant source of greenhouse gas emissions, accounting for 11.1%-19.6% of global GHGs. The primary sources of greenhouse gas emissions from livestock production include enteric methane from cattle, manure, feed production, land conversions, energy use, and livestock processing and packing. 

By choosing plant-based meals more often, you can lessen the demand for meat production, thereby reducing your environmental footprint. Transitioning towards a plant-based diet is not only beneficial for the planet but also for health.

Animal Extinction

Animal extinction is another pressing environmental challenge we are facing. Understanding Global Change notes that a species is considered extinct when it no longer exists anywhere on Earth. This irreversible loss typically results from the inability of the last remaining individuals of a species to meet their basic needs for food, water, shelter, and space.

Before an animal becomes extinct, it often passes through various stages of vulnerability that signal its decreasing population and heightened risk of disappearing forever. Being categorized as endangered signifies that a species is on the cusp of extinction in the foreseeable future. To better understand and address this urgent issue, conservationists have defined three levels of endangerment: near-threatened, endangered, and critically endangered.

  • Near-Threatened: A species labeled as near threatened is close to qualifying for a higher risk category in the near future. While not yet endangered, these species are experiencing significant threats that could lead to their decline if not addressed.
  • Endangered: This status indicates that a species faces a very high risk of extinction in the wild unless immediate and effective conservation measures are taken. Factors such as habitat loss, pollution, or overhunting typically contribute to their rapid decline.
  • Critically Endangered: The most urgent level before extinction, critically endangered means a species is at an extremely high risk of extinction in the immediate future. At this stage, every remaining individual is vital for the species’ survival, and swift action is necessary to prevent a total loss.

The International Union for Conservation of Nature’s (IUCN) Red List of Threatened Species reveals that over 44,000 species are on the brink of extinction, constituting 28% of the 157,100 species evaluated. 

The World Wildlife Fund (WWF) pinpoints the rapid decline in biodiversity as the primary catalyst for animal extinction, with major contributing factors being changes in land use, unsustainable exploitation of natural resources, the introduction of invasive species not native to the area, climate change, and pollution. 

Additionally, the situation is exacerbated by growing human populations and consumerism, heightened production of waste and pollutants, expansion of urban areas, and international conflicts. 

What You Can Do to Help

Knowing the precarious situation many animal species face, there are several proactive steps you can take to help mitigate these issues. Minor as these actions may be, they can contribute to conserving animals’ habitats, encourage biodiversity, and prevent animal extinction. Here are some impactful measures you can implement:

Avoid Products Made From Endangered Species or Unsustainable Sources

Many products on the market, such as ivory, exotic animal skins, and certain types of wood, come from endangered species or habitats under threat. Purchasing these items directly supports harmful practices and contributes to the demand that drives poaching and exploitation of vulnerable species. 

Instead, opt for alternatives certified as sustainable or made from materials that do not harm the environment or wildlife. By making conscious consumer choices, you play a part in reducing the economic incentives for illegal wildlife trade and habitat destruction, further protecting species at risk of extinction.

Being mindful of where your products come from and choosing to support sustainable and ethical sources is a powerful way to contribute to preserving biodiversity and the well-being of our planet’s ecosystems.

The video below, produced by BBC Earth, sheds light on the heartbreaking reality of elephant poaching driven by the demand for luxury ivory products.

Active engagement in advocating for policies that protect the environment and its inhabitants is crucial. You can help influence legislative actions by voicing support for stronger protection laws and sustainable practices at local, national, and global levels. This can lead to the implementation of more effective measures against habitat destruction, pollution, and other factors contributing to species endangerment.

Plant Native Plants

Integrating native plants into your garden or community spaces provides essential habitats and food sources for local wildlife, including pollinators, birds, and small mammals. Native flora is adapted to the local climate and soil conditions, making it more resilient and requiring less water and maintenance than non-native species. By choosing native plants, you contribute to restoring local ecosystems, supporting biodiversity, and creating corridors for wildlife to thrive even in urban areas.


Pollution is another formidable challenge, presenting significant threats to environmental integrity, human health, and economic sustainability.

National Geographic defines pollution as the process through which harmful substances, known as pollutants, are introduced into the environment. Pollution manifests in various forms – air, water, soil, and noise pollution are the most prevalent, each with distinct sources and consequences. 

  • Air pollution primarily results from industrial emissions, vehicle exhausts, and burning fossil fuels, leading to respiratory problems in humans and animals and contributing to climate change. 
  • Water pollution arises from industrial discharge, agricultural runoff, and untreated sewage entering water bodies, affecting aquatic life and contaminating drinking water sources. 
  • Soil pollution is often a result of chemical spills, industrial activity, and improper disposal of waste, leading to degraded land quality and reduced agricultural productivity. 
  • Noise pollution, though less discussed, significantly impacts mental and physical health.

The consequences of pollution are far-reaching. In the environment, it can lead to the degradation of ecosystems, harming wildlife, and destroying habitats. For humans, exposure to pollution has been linked to various health issues, from respiratory ailments caused by poor air quality to waterborne diseases stemming from contaminated water supplies. Economically, pollution can impose high costs due to its impact on productivity levels, healthcare expenses, and biodiversity loss.

What You Can Do to Help

Embracing a more mindful and proactive approach towards our daily habits and choices is essential to combat pollution effectively. Below are actionable steps that you can adopt to make a substantial impact:

Reduce Single-Use Plastics 

Single-use plastics are one of the most prominent sources of pollution, particularly in oceans and waterways. Annually, coastal nations contribute approximately eight million tons of plastic waste to the oceans. This staggering amount is akin to placing five garbage bags filled with trash on every foot of coastline across the globe. 

Opting for reusable bags, bottles, and containers can significantly minimize this waste. Reducing your reliance on plastic can help protect marine life, decrease landfill waste, and lower the demand for plastic production, which is energy-intensive and polluting.
