(a) Conservation: Conservation refers to the preservation, protection, and sustainable use of natural resources, including plants, animals, water, and minerals, to maintain the overall balance of ecosystems and ensure their long-term viability.

One activity of humans associated with conservation is the establishment and management of protected areas, such as national parks, wildlife sanctuaries, and nature reserves. These areas are designated to safeguard biodiversity and provide a safe habitat for different species. Through proper management practices, humans aim to preserve rare and endangered species, protect critical ecosystems, and prevent habitat destruction.

(b) Pollution: Pollution refers to the introduction of harmful substances or contaminants into the environment, which can have adverse effects on living organisms, ecosystems, and the overall balance of nature.

One activity of humans associated with pollution is the emission of pollutants from vehicles. As humans rely heavily on cars, trucks, and motorcycles for transportation, the burning of fossil fuels releases gases, such as carbon monoxide, nitrogen dioxide, and sulfur dioxide, into the atmosphere. These pollutants contribute to air pollution, leading to respiratory problems, climate change, and damage to ecosystems. Efforts to reduce vehicle emissions and shift towards cleaner transportation alternatives like electric vehicles are essential for mitigating pollution.
