Biodiversity impact refers to the effect that human activities and environmental changes have on the variety and variability of life forms within a given ecosystem or the planet as a whole. It encompasses both the loss and the enhancement of species diversity, genetic variation, and ecosystem services, which are crucial for maintaining ecological balance and resilience against disturbances.

Biodiversity Impact

Human activities encompass the diverse range of actions and behaviors carried out by humans to sustain life, fulfill needs, and pursue interests. These activities impact the environment, society, and economy, shaping the world we live in through both positive and negative consequences.

Human Activities

Environmental changes refer to the alterations in the natural or human-made environment that can affect ecosystems, biodiversity, and human societies. These changes can be driven by natural processes or human activities, leading to impacts such as climate change, habitat loss, and pollution.

Environmental Changes

Variety and variability of life forms

Given ecosystem

Species diversity is a critical component of biodiversity, encompassing the variety and abundance of different species within a given ecosystem. It plays a vital role in ecosystem resilience, productivity, and the provision of ecosystem services, while also being influenced by factors such as habitat loss, climate change, and human activities.

Species Diversity

Genetic variation refers to the differences in DNA sequences among individuals within a population, which is crucial for evolution and adaptation to changing environments. It arises from mutations, genetic recombination during sexual reproduction, and gene flow between populations, providing the raw material for natural selection to act upon.

Genetic Variation

Ecosystem services are the benefits that humans derive from natural ecosystems, encompassing provisioning, regulating, cultural, and supporting services. These services are crucial for human survival and well-being, as they include essential processes like pollination, water purification, climate regulation, and nutrient cycling.

Ecosystem Services

Ecological balance refers to the equilibrium between living organisms and their environment, ensuring the sustainability of ecosystems. It involves complex interactions and dependencies that maintain biodiversity and the natural processes necessary for life on Earth.
