Introduction In the era of climate change and depleting fossil fuels, the global energy demand is driving innovation toward sustainable and eco-friendly alternatives. Among the many renewable energy sources, biofuels, especially those derived from algae, are emerging as promising substitutes for conventional fuels. They offer the potential to reduce greenhouse gas emissions, enhance energy security,…
Introduction In the global fight against climate change, reducing carbon dioxide (CO₂) emissions has become paramount. Carbon Capture and Storage (CCS) is a technological approach designed to capture CO₂ emissions from industrial processes and power plants before they enter the atmosphere, then securely store them underground or use them for beneficial purposes. This method aims…
Introduction Climate change has emerged as one of the most pressing global challenges, with rising temperatures, melting glaciers, and erratic weather patterns disrupting ecosystems and livelihoods. In this context, achieving net zero emissions—a state where the amount of greenhouse gases emitted is balanced by the amount removed from the atmosphere—has become a critical target for…
Introduction In an era where environmental degradation and resource depletion are major concerns, the search for sustainable solutions often leads us back to age-old practices that have long coexisted with nature. Traditional Ecological Knowledge (TEK) — the cumulative body of knowledge, practices, and beliefs regarding the relationship of living beings with one another and their…
Introduction Urbanization is a defining characteristic of the 21st century. As the global population continues to rise, more people are moving from rural areas to urban centers in search of better opportunities, economic growth, and modern lifestyles. One of the most significant outcomes of this demographic shift is the rise of megacities — urban areas…
Introduction In an era characterized by frequent and increasingly severe natural and man-made disasters, from hurricanes and floods to wildfires and pandemics, post-disaster recovery planning has become an essential component of community preparedness and sustainable development. Beyond immediate emergency response, recovery planning serves as a blueprint for restoring livelihoods, rebuilding infrastructure, and enhancing the long-term…
Introduction to Watersheds A watershed is a land area that drains or “sheds” water into a common body of water, such as a river, lake, or ocean. It is defined by the boundaries of the highest points of land, which direct rainfall and other forms of precipitation into streams, rivers, or other water sources within…
Introduction The modern world faces increasing environmental challenges, including pollution, plastic waste, and resource depletion. Bioengineering and biodegradable materials have emerged as transformative solutions to these global issues. Bioengineering applies principles of biology and engineering to create sustainable materials, while biodegradable materials naturally decompose, reducing environmental impact. This essay explores the science behind bioengineering, the…
Introduction Plastic pollution has become one of the most pressing environmental issues of our time. With millions of tons of plastic waste ending up in landfills and oceans every year, the need for effective recycling methods is more critical than ever. Traditional plastic recycling methods have their limitations, often resulting in downcycled products that do…
Introduction Renewable energy is a sustainable and environmentally friendly source of power derived from natural processes that are continuously replenished. Among the most significant renewable energy sources are solar energy, wind energy, and geothermal energy. These energy sources play a crucial role in reducing dependence on fossil fuels, mitigating climate change, and promoting sustainable development….
