BIODIVERSITY AND DISEASES

Biodiversity degradation
Disturbances to biotic factors (temperature, light, water, humidity, wind, air currents, pH, topography, etc.) and abiotic factors (predation, competition, habitat, pollination and mimicry - resemblance between animals and part of a plant/species happens to be unpalatable to a predator) will lead to environmental resistance.
This is due to:
  • shortage of food, water and oxygen
  • low light intensity
  • predators and parasites
  • destruction of habitat
  • diseases
  • accumulation of toxic waste
  • psychological factors
  • harsh climate
Emergence of variant diseases
Accumulation of poisonous /hazardous substance incorporated into the physiological functions & systems of every living organisms , including microorganisms like bacteria.
Harmless microorganisms due to evolution undergoes rapid mutation of deleterious genes into pathogenic / viral microorganisms.
Diversifications with the existence of ‘superclasses’ of microorganisms (super virus) which are aggressive & invasive against the protective immunities provided by the immune systems in organisms.
More powerful & larger doses of medications, ranging from vaccines to antibiotics produced to battle & immunize against stronger pathogen attack
