Biodiversity and Human Impact on the Environment

While transport is essential for modern life, it is not a direct biological or social driver of population growth in the same way that improved medicine, food security, and living conditions are.

Water pollution can be caused by various sources, including agricultural runoff (pesticides/fertilizers), industrial waste, sewage, and leaching from landfill sites.

Peat bogs are drained and harvested primarily for use as garden compost. While other factors like climate change affect peatlands, the direct destruction is largely driven by this commercial demand.

Sulfur dioxide reacts with water vapor in the atmosphere to form sulfuric acid, which falls as acid rain. Global warming is primarily associated with carbon dioxide and methane.

Photosynthesis is the process by which plants and algae absorb carbon dioxide from the atmosphere to produce glucose. Respiration and combustion release carbon dioxide into the atmosphere.

Global warming refers to the rise in Earth's temperature due to greenhouse gases. Increased paper production is an industrial activity that may contribute to deforestation, but it is not a direct climatic effect of global warming.

Deforestation is the clearing of forests for land use or resources. Breeding programmes are conservation efforts intended to protect species, not destroy forests.

Rice paddies are flooded, creating anaerobic conditions where bacteria produce large amounts of methane. While other activities produce methane, rice cultivation is a major agricultural source.

Combustion of fossil fuels releases carbon dioxide as a product of oxidation. Sulfur dioxide is also released due to sulfur impurities commonly found in coal and oil.

Biodiversity refers to the variety of life in a habitat. Deforestation destroys habitats, leading to the loss of species and a reduction in biodiversity.

Biodiversity is defined as the variety of all living organisms on Earth or in a particular ecosystem. It encompasses the range of different species present.
