Ecology is important because of the insights it provides about the ways in which people and nature depend on one another. Understanding the workings of ecological systems more completely allows for predictions about the ways human activities affect the health of the earth over time.Know More
People who study ecology focus on ways to preserve different types of habitats and the biodiversity within each. One particular biome that is at risk is the heathlands of Western Europe. Researchers have looked at heather (the primary plant in this biome) to understand ways that the traditional management techniques (cutting, burning or grazing) influenced the species living inside it. This research has yielded ways to manage and conserve the heathland more effectively, allowing its unique species to thrive.
While global warming is a hot topic in the media, ecological researchers identify specific mechanisms that are causing climate change around the world. While fossil fuel consumption takes up much of the media space devoted to global warming, ecologists focus more on the specific effects of global warming on different species within different biomes, by analyzing the potential effects of elevated amounts of different toxins and gases in the environment, with particular emphasis on forestry and crop yields as well as distribution of animal and plant species after global temperatures elevate.Learn more in Earth Science
The ozone layer is important because it blocks ultraviolet radiation from the sun that causes many detrimental effects to living things. Ultraviolet radiation affects a plant's ability to grow and can cause skin cancer and cataracts in humans. Ultraviolet radiation also affects the fertility rate of some animals.Full Answer >
Nitrogen is important because it sees a significant amount of use in the agricultural sector: it is an additive in many commercial fertilizers and is sprayed on crop fields to reduce the risk of insect infestation and crop failure. Nitrogen is produced using natural gas and air, which are readily available in the environment. The availability of its raw materials makes nitrogen fertilizers and pesticides relatively easy to produce.Full Answer >
The equator is important as a reference point for navigation and geography. It's an imaginary line that divides the Earth into two equal halves, and it forms the halfway point between the South Pole and the North Pole at 0 degrees latitude, according to National Geographic. It is also important because twice a year, during the spring and autumn equinoxes, the sun passes directly over it.Full Answer >
The Mississippi River is important due to its necessity in American commerce. Cities such as New Orleans, St. Louis and Minneapolis all get water from the river.Full Answer >
