Humans and their Environmental Impact Quiz

Carbon dioxide is the primary greenhouse gas, trapping heat in the atmosphere and contributing to global warming.

Extinction refers to the permanent loss of a species from a particular habitat or from the entire planet, often due to human activities.

Lead is a key component of electronic waste (e-waste) and poses significant environmental hazards, including soil and water contamination, as well as adverse health effects on humans and wildlife.

Deforestation, often to clear land for agriculture or grazing, exposes soil to erosion by wind and water, leading to the loss of fertile topsoil and degradation of land.

Sulfur dioxide, primarily emitted from burning fossil fuels containing sulfur compounds, is a major contributor to acid rain, which can lead to environmental damage, including soil and water acidification, and harm to aquatic life and vegetation.

Sewage disposal from human activities is the main source of water pollution, contaminating water bodies with pathogens and chemicals.

Deforestation leads to the loss of habitat for various species, disrupting ecosystems and contributing to biodiversity loss.

Vehicle emissions, including pollutants like nitrogen oxides and particulate matter, are a major contributor to air pollution in urban areas, leading to various health and environmental impacts.

Global warming, primarily due to the increase in greenhouse gas emissions, leads to coral bleaching by causing the expulsion of symbiotic algae from coral tissues, which disrupts the coral's ability to obtain nutrients and results in its whitening.

Recycling is the process of converting waste materials into reusable materials to prevent them from ending up in landfills or incinerators, conserving resources and reducing environmental impacts.

Coal is a non-renewable energy source formed from the remains of plants and animals buried millions of years ago. Its combustion releases carbon dioxide and other pollutants, contributing to air pollution and climate change.

Bioremediation refers to the process of using living organisms to degrade or remove pollutants from the environment, restoring contaminated sites.

The Montreal Protocol is an international agreement aimed at phasing out the production and use of ozone-depleting substances, such as chlorofluorocarbons (CFCs), to protect the ozone layer.

The thinning of the ozone layer, primarily caused by human-made chemicals like CFCs and halons, leads to ozone depletion, which can result in increased UV radiation reaching the Earth's surface, posing risks to human health and the environment.

Biomagnification refers to the process where certain pollutants or toxins accumulate and increase in concentration as they move up the food chain, posing risks to organisms at higher trophic levels.

Eutrophication, often caused by excessive nutrient runoff from agricultural activities or sewage, leads to the overgrowth of algae, which depletes oxygen levels in water bodies, resulting in 'dead zones' where aquatic life cannot survive.

The Convention on Biological Diversity (CBD) is an international organization that focuses on the conservation of biodiversity and the sustainable use of natural resources to ensure the well-being of present and future generations.
