People should strive to protect endangered species. Since all species are interconnected, the extinction of one could have far reaching and detrimental effects on others, notes Curiosity.com from Discovery.Know More
Humans are responsible for the loss of many species of wildlife, insects and birds. In Yellowstone National Park, a decline in the population of gray wolves affected the elk population, and its numbers increased. This caused widespread destruction of trees around the water bodies. Migrating birds did not have any place to nest, and the water was too hot for the trout. Gray wolves had to be reintroduced into the park to control the elk population and reduce the impact on the trees.
The honey bee is another species that is affected by human activity. Honey bee numbers are dwindling due to excessive use of pesticides. Bees are responsible for pollinating fruits, vegetables and nuts. If humans do not step up and protect the honey bee population, then 90 different food plants will disappear and greatly affect what humans consume. Gene banks collect and store DNA from species that are endangered. This makes it possible for scientists to clone a particular species if it faces extinction in the future. In this delicate ecosystem, humans have objectively coherent, observable reasons to do their bit to save species that are on the verge of extinction.Learn more in Environmental Science
Directional selection is a type of natural selection that occurs when conditions favor a specific characteristic of a species over another. This type of selection increases the frequency distribution of these characteristics, while the other characteristics drop away.Full Answer >
The Endangered Species Act helps to revive dwindling populations of critically endangered species and promotes environmental preservation, but it may be time consuming and costly to implement. The Endangered Species Act is a legal tool used to identify and protect endangered species at the federal level in the United States. It helps to raise awareness of imperiled plant and animal species, but it can also put vulnerable species in jeopardy and takes quite a bit of time and finances to implement.Full Answer >
If a study shows that people who wear glasses have above average intelligence, assuming that everyone who wears glasses is intelligent is an example of ecological fallacy. Applying an ecological fallacy occurs when group data is used to draw conclusions about individuals.Full Answer >
A manmade ecosystem is an artificial biological system that is managed and sustained by people. The same components that interact in a natural ecosystem are also present in this simulated type of biological community. In the absence of human interference, a manmade ecosystem fails to thrive.Full Answer >
