Introduction Ecosystems are dynamic networks of living organisms and their physical environments. Within these networks, various species coexist, interact, and depend on each other for survival. However, resources such as food, space, and shelter are often limited, leading to potential competition. If multiple species rely on the same resources, competitive exclusion may occur, where one…
Introduction Biodiversity is a cornerstone of ecological balance and sustainability. However, one of the most significant threats to native biodiversity—often overshadowed by issues like pollution and deforestation—is the introduction and spread of invasive alien species (IAS). In India, a biodiversity-rich country with a wide range of ecosystems, invasive species pose a major threat to native…
Biodiversity, or biological diversity, refers to the variety of life on Earth, including different species of plants, animals, fungi, and microorganisms, the genetic differences within these species, and the ecosystems they form. It plays a crucial role in maintaining ecological balance, supporting human livelihoods, and contributing to cultural and economic well-being. Biodiversity is essential for…
Introduction Climate change is one of the most pressing global challenges of the 21st century, with its effects disproportionately impacting developing countries. Despite contributing the least to greenhouse gas emissions, these nations bear the highest burden of climate-related disasters such as rising temperatures, extreme weather events, sea-level rise, water scarcity, and agricultural disruptions. Developing countries,…
Introduction The increasing frequency of zoonotic diseases—those that spread between animals and humans—has underscored the importance of a holistic, interdisciplinary strategy for global health. The One Health approach recognizes the interconnectedness of human, animal, and environmental health, promoting collaboration among experts from various fields to prevent and control emerging infectious diseases. Technological advancements have become…
Introduction Wildlife conservation is an issue of paramount importance for the future of our planet. With the growing threats to biodiversity, including habitat destruction, poaching, and climate change, the conservation of wildlife has become more crucial than ever. The loss of species not only impacts the delicate balance of ecosystems but also jeopardizes the economic,…
Urbanization, the process by which cities and towns expand as human populations increase, is one of the most transformative forces shaping the modern world. As human settlements grow, they encroach upon natural landscapes, leading to the destruction or alteration of wildlife habitats. This widespread urban sprawl has profound consequences for biodiversity, ecosystem services, and the…
Disasters can be broadly categorized into natural and manmade (or anthropogenic) types, based on their origin and cause. Both types can have devastating effects on human life, infrastructure, and ecosystems, but their sources, characteristics, and the measures taken to mitigate them often differ significantly. Natural Disasters Natural disasters are catastrophic events that occur as a…
