What are 6 major causes of an unbalanced ecosystem?

Answer 1

• Nuclear Inventions, attacks
• Over fishing
  
• Hunting
• Improper use of nonrenewable resourses
• Cutting down the jungles
• Chemical waste left in the sea

These all things have affected not only humans but all the living beings on the earth. These are the causes of climatic changes & biodiversity loss.

· 99% of threatened species are at risk from human activities.

· Habitat loss and degradation are the leading threats. They affect 86% of all threatened birds, 86% of the threatened mammals assessed and 88% of the threatened amphibians.

· Introductions of alien species. Some of the worst include cats and rats, green crabs, zebra mussels, the African tulip tree and the brown tree snake. Introductions of alien species can happen deliberately or unintentionally, for example, by organisms "hitch-hiking" in containers, ships, cars or soil.

· Over-exploitation. Resource extraction, hunting, and fishing for food, pets, and medicine threatens many species.

· Pollution and diseases.

· Human-induced climate change is increasingly recognized as a crucial threat. Climate change is altering migratory species patterns, causing coral bleaching, etc.

Answer 2

POLLUTION ON A/C OF INDUSTRIALIZATION, FUEL CONSUMPTION, AIR CONDITIONING EQUIPMENTS, DEFORESTATION, NON-PLANTATION OF SUFFICIENT PLANTS, DISPROPORTION IN CULTIVATED LAND, EXPANSION OF URBAN AREA AND VICE VERSA, CHANGE OF POSITION OF WATER RESERVOIR ETC.
Ecological imbalance is caused by humans. With no humans on earth, nature would always be in balance. Humans attempt to control and use the earth for their own purposes that go far beyond basic life and survival. Once the natural processes are interfered with, ecological imbalances result.

Answer 3

Causes are integrated health management of crops soil and animals.

Answer 4

because of natural disasters , deforestation , poaching

Answer 5

Habitat Destruction, resource Depletion, pollution, climate change, waste disposal, and invasive species
