PRINCIPAL CAUSES FOR THE LOSS OF VARIETY OF LIFE ON EARTH - Coggle Diagram
PRINCIPAL CAUSES FOR THE LOSS OF VARIETY OF LIFE ON EARTH
POLLUTION
Despite having existed for a long time, organisms still have to accept living in a polluted environment
Air pollutants
Soot, dust, ammonia, or carbon dioxide
Directly and indirectly influence biodiversity
WATER POLLUTION
Had detrimental effect on biodiversity
Causes and impacts
Chemical fertilizers
Contain nitrogen and phosphorous
Increase the crop productivity
Sweep away to the water bodies or underground
Eutrophication (excessive plant growth)
Reduction of oxygen level (lack of dissolved oxygen in water) => Low biodiversity
Pesticides
Fertilizers are not washed away
Negatively affect non-flowing waterbodies
Animals in water bodies are difficult in breeding
Various anthropogenic activities
Lead to put heavy metals into the water bodies
Affect the behaviorz
Also the survival rates of aquatic animals (specially fish)
Oil spills
Impact the wildlife greatly
Suffocation
Impair the organisms's significant organs
Reduce growth rates
Cause the higher death of the larvae
Disrupt the animal's sense
LIGHT POLLUTION
SOIL POLLUTION
AIR POLLUTION
Impact on animals
Negatively influence their well-being
behavioral alterations
the egg laying capability
The reproductive ability of the animals and hence success in breeding
The respiratory apparatus
Difficult to examine in controlled environment
Nitrous oxide, carbon dioxide, methane
Swiftly modifying the climate of the earth => The animals and plants find it difficult to adjust => influence the biodiversity
Acid rain
Enhanced build-up of the mucus in fish gills => suffocation
Soil
Easily cause acid rain => reduce microbial activity => influences the food chain and other forms of life
NOISE POLLUTION
