Introduction

Environmental issues are among the most pressing concerns facing our society today. Understanding the complex relationships between environmental problems, humans, other organisms, and the broader environment is crucial for developing effective solutions. In this paper, I will identify three specific environmental science problems, analyze their impacts on humans, other organisms, and the environment, and support my discussion with credible scientific sources.

Problem 1: Climate Change

Climate change, primarily driven by greenhouse gas emissions from human activities such as burning fossil fuels and deforestation, represents a significant threat to global ecosystems and societies. To humans, climate change results in increased incidences of extreme weather events like hurricanes, droughts, and heatwaves, which can lead to loss of life, economic instability, and health issues (NASA, 2022). For other organisms, the rapid shifts in temperature, altered precipitation patterns, and rising sea levels threaten habitats and biodiversity; many species face extinction if they cannot adapt quickly (Doney et al., 2012). The environment itself suffers as ecosystems such as coral reefs undergo bleaching, and soil and water resources become more stressed (IPCC, 2021).

Problem 2: Plastic Pollution

Plastic pollution has become pervasive in oceans, rivers, and landscapes due to improper waste management and widespread usage of disposable plastics. Humans are affected through health risks associated with microplastics entering the food chain, such as ingestion of contaminated seafood, which can cause endocrine disruption and other health issues (Galloway et al., 2017). Other organisms, including marine life such as fish, turtles, and seabirds, ingest or become entangled in plastic debris, leading to injury, starvation, and death (Derraik, 2002). The broader environment suffers as plastic materials break down into microplastics that persist for hundreds of years, contaminating water bodies and soils, disrupting natural processes (Andrady, 2011).

Problem 3: Deforestation

Deforestation, mainly caused by agriculture, logging, and urban expansion, significantly alters landscapes and ecosystems. For humans, deforestation leads to reduced air quality, climate regulation, and increased vulnerability to natural disasters such as floods and landslides (Brack et al., 2012). Other organisms are directly impacted as their habitats are destroyed, forcing wildlife to migrate or face extinction, ultimately reducing biodiversity (Haddad et al., 2015). The environment suffers as forests act as carbon sinks, and their removal accelerates climate change, while soil erosion and water cycle disruptions degrade land quality and water availability (Houghton, 2012).

Conclusion

These three environmental problems—climate change, plastic pollution, and deforestation—demonstrate the interconnectedness of human activities, other organisms, and the environment. Addressing these issues requires coordinated global efforts and sustainable practices informed by scientific research. Recognizing the impacts and understanding the underlying factors are crucial steps toward mitigating environmental degradation and ensuring a healthier planet for current and future generations.
