What is environmental equilibrium and ecological imbalance?
Environmental Equilibrium and Ecological Imbalance
Environmental Equilibrium:
Environmental equilibrium refers to a state of balance or harmony in the natural environment where different ecosystems, species, and processes coexist and interact in a sustainable manner. It is a state where the Earth's natural systems are in balance, ensuring the stability and health of the environment. This balance is crucial for the survival and well-being of all living organisms, including humans.
Key points about environmental equilibrium:
- It involves the proper functioning and interaction of various components of the ecosystem, such as air, water, soil, plants, and animals.
- It ensures the maintenance of biodiversity, which is essential for ecosystem resilience and productivity.
- Environmental equilibrium helps regulate climate, nutrient cycling, and other essential processes that support life on Earth.
- Human activities, such as deforestation, pollution, and habitat destruction, can disrupt environmental equilibrium and lead to ecological imbalance.
Ecological Imbalance:
Ecological imbalance occurs when there is a disruption or disturbance in the natural balance of an ecosystem. This disruption can result from natural factors such as volcanic eruptions or earthquakes, but more commonly, it is caused by human activities that alter the environment in harmful ways. Ecological imbalance can have serious consequences for biodiversity, ecosystem function, and human well-being.
Key points about ecological imbalance:
- It can lead to the loss of biodiversity, as certain species may become extinct or endangered due to changes in their habitat or food sources.
- Ecological imbalance can disrupt ecosystem services, such as pollination, water purification, and carbon sequestration, which are essential for human survival.
- It can result in the spread of invasive species, diseases, and pests, which can further destabilize ecosystems.
- Addressing ecological imbalance requires taking action to restore and protect natural habitats, reduce pollution, and promote sustainable resource management practices.
In conclusion, maintaining environmental equilibrium is essential for the health and sustainability of the planet, while addressing ecological imbalance is crucial to prevent further damage to ecosystems and ensure a better future for all living organisms.

Similar UPSC Doubts

Many farmers use synthetic pesticides to kill infesting insects. The consumption of pesticides in some of the developed countries is touching 3000 grams/hectare. Unfortunately, there are reports that these compounds possess inherent toxicities that endanger the health of the farm operators, consumers and the environment. Synthetic pesticides are generally persistent in environment. Entering in food chain they destroy the microbial diversity and cause ecological imbalance. Their indiscriminate use has resulted in development of resistance among insects to insecticides, upsetting of balance in nature and resurgence of treated populations. Natural pest control using the botanical pesticides is safer to the user and the environment because they break down into harmless compounds within hours or days in the presence of sunlight. Plants with pesticidal properties have been in nature for millions of years without any ill or adverse effects on the ecosystem. They are easily decomposed by many microbes common in most soil. They help in the maintenance of biological diversity, of predators and the reduction of environmental contamination and human health hazards. Botanical pesticides formulated from plants are biodegradable and their use in crop protection is a practical sustainable alternative.On the basis of the above passage, the following assumptions have been made.1. Synthetic pesticides should never be used in modem agriculture.2. One of the aims of sustainable agriculture is to ensure minimal ecological imbalance.3. Botanical pesticides are more effective as compared to synthetic pesticides.Q.Which of the assumptions given above is/are correct?
