How are humans causing extinction? The current extinction crisis is entirely of our own making. More than a century of habitat destruction, pollution, the spread of invasive species, overharvest from the wild, climate change, population growth and other human activities have pushed nature to the brink.
What are the consequences of extinction of invertebrates for human well being? Human Health — decreasing invertebrate numbers are known to compromise food production due to reduced pollination, seed dispersal and insect predation but the impact the continuing loss of animals, including invertebrates, has on the spread of human disease needs to be better understood as a priority.
Why are invertebrates important to humans? Invertebrates provide services essential to ecosystem function, human society and economy. Services provided by invertebrates range from pollination of crops and wildflowers to soil creation and maintenance to habitat creation itself. they also control pests, while themselves providing a food source for other animals.

how does extinction start?
Extinction occurs when species are diminished because of environmental forces such as habitat fragmentation, climate change, natural disaster, overexploitation by humans, and pollution, or because of evolutionary changes in their members (genetic inbreeding, poor reproduction, decline in population numbers).
what will happen if green sea turtles become extinct?
If sea turtles went extinct, dune vegetation would lose a major source of nutrients and would not be as healthy and would not be strong enough to maintain the dunes, resulting in increased erosion.
