Environmental Conservation

Study Notes

Recycling involves converting waste materials into new materials and objects to prevent waste of potentially useful resources.
Household waste includes garbage, recyclable materials, and organic waste produced from household activities.
Overuse of pesticides can harm the environment, wildlife, and human health.
Deforestation results in habitat loss and environmental damage due to large-scale removal of forested areas.
Urban development leads to changes in land use and infrastructure, causing expansion and growth of cities and towns.

Ozone layer depletion occurs due to chemical pollutants, leading to increased UV radiation reaching the Earth's surface.
Coral bleaching is caused by stress factors like increased water temperature, leading to the expulsion of symbiotic algae.
Water contamination makes water unsafe for consumption and ecosystems due to the presence of harmful substances.
Sewage is waste water and excrement conveyed in sewers, usually from households and industry.

Conservation involves protecting and preserving natural resources and the environment.
Wildlife reserves are protected areas for the conservation of wild animals and their habitats.
Biodegradable materials can be decomposed by bacteria or other living organisms, avoiding pollution.
Recycling helps to prevent waste of potentially useful resources.

Fossil fuels are natural fuels formed from the remains of ancient plants and animals.
Carbon dioxide is a colorless, odorless gas produced by burning carbon-based fuels and by respiration, contributing to the greenhouse effect.

Landfill sites are designated locations for the disposal of waste by burying it, typically involving layers of earth to cover the waste.
To dump means to dispose of waste material in a careless or improper way.
To discard means to throw away or get rid of something that is no longer needed.
To use up means to consume all of something so that none remains.

To breed means for animals or plants to reproduce and produce offspring.
To devise a scheme means to plan or invent a method or strategy for achieving a particular goal.
To deposit means to lay down or place something in a specific location, often in layers.
Genetically modified organisms have their genetic material altered using genetic engineering techniques to introduce new traits.
Sediment is particles of soil, sand, and minerals washed from land into water bodies, which can accumulate and affect water quality and ecosystems.
