What word describes what happens to plant and animal life when humans make a major change in the environment?

The Word that best describes what happens to plant and animal life when humans make a major change in the environment is "disturbance". Major changes to the environment can disturb the delicate balance of the natural ecosystem and cause a disruption in the balance of the food chain. This disruption can have a ripple effect on the survival of certain plants and animals who depend on the natural environment to survive. The following are some of the potential effects of a major environmental disturbance:

• Introduction of non-native species
• Loss of biodiversity
• Decrease of available food sources
• Alteration of water sources
• Changes in temperature and climate

The effects of a major environmental disturbance can have long-term consequences on the health and well-being of plants and animals. Human intervention in the environment should be done responsibly with consideration for the plants and animals that depend on the natural balance of the environment.
