Conservation and pollution Flashcards
Conservation
Is the protection, preservation and careful use of our natural resources
Our natural resources include land, rivers, seas, plants and animals
If we don’t protect these the environment could be destroyed and plants and animals may become extinct
Pollution
Pollution is adding unwanted wastes to the environment causing damage to it
if one organism is damaged it can be harmful to many other plants and animals
the balance of nature can be damaged
Air pollution
Air Pollution: caused by smoke, dust and harmful gases - most of these come from cars, buses, factories and power stations
Acid rain
When fossil fuels are burned they produce gases called carbon dioxide and sulfur dioxide
These dissolve in rainwater to form carbonic acid and sulfuric acid
This acid rain damages plants and buildings
Soil pollution
Caused by Pesticides, Artificial fertilisers and acid rain
These chemicals sink into the soil and can be absorbed by plants
They then get passed up the food chain and can cause illness
The chemicals can also seep into rivers and cause pollution there
Water Pollution
Bodies of water are polluted by fertilisers, sewage, oil and detergents
Fertilisers seep into rivers and cause too much plant growth, bacteria populations boom as they feed on dead plants and no oxygen is left for fish
Incineration
Burning the waste. this can release dangerous gases into the atmosphere, difficulties with location nobody wants to live near an incinerator
Landfill
Burying the waste in ground and damages soil, rivers and ground water. It attracts rodents, disease causing, bad smell. difficulties as nobody wants to live near landfill sites
Recycling
Paper, glass, some metals and plastics can be processed and reused
This reduces damage to the environment
