How does wildlife extinction impact the world?

All living things and the physical world are interconnected. The relationships are in the millions. We have only studied a fraction of these interrelationships, so while extinctions continue to occur we are losing knowledge about our only home, Earth. We have no complete idea what impacts the continued destruction of the earth's biodiversiy will have on us or the earth-so we are playing a dangerous game. Which creatures can survive the onslaught of man? think about it - prob in the end just the creepy crawly ones and the microbes. As humans grow in numbers it seems we have a continuously growing appetite to rape the earth of all its resources. Its called greed.


Wildlife exticntion continues to affect the world in known ways and unknown ways. Our environment, the only one we have, can be irreversibly altered- and we are still only learning how this incredible planet lives, breathes, recyles, interacts with space etc etc. Remember that wildlife destruction goes hand in hand with habitat destruction (which by itself affects the planet). The two are related. We are opening a minefield of problems. Study env science and be one of the people that views this world holistically and not just how they can get their needs met by it.How does wildlife extinction impact the world?
Like tugging on the thread from a blanket or tapestry, once you pull too many loose, the tapestry unravels. (ie is destroyed)How does wildlife extinction impact the world?
It makes tree huggers sad
say we killed all hawks and hawks ate rats. so the rat population would grow too fast, and the rats would eat up all the food. PROBLEM 1: no more food. then the rats would die out. PROBLEM 2: death of other species. then the eaters of rats, say eagles, would die out because there is no more food. PROBLEM 3: continual, growing cycle.





So in conclusion, the problems are the following:


no more food


death of other species


continual, growing cycle of loss of food and subsequent death.
This depends on the species. If a certain species became extinct, it would affect another species that hunted the extinct species for prey. In turn, the predator may become extinct, due to the fact that it's primary food source no longer exists. Alternatively, it would look for alternative food sources, causing further extinction to another species. This goes on up the food chain, in a sort of chaos theory reaction, until, in worst case scenario, the predator at the top too becomes extinct, so one extinction caused the erradication of an entire small eco-system.
