Environmental science is the study of nature and how humans impact it. It encompasses many fields such as atmosphere, oceans, geology and habitats; plus it deals with essential cycles like water, carbon dioxide, oxygen nitrogen phosphorus which support life on Earth.

The environment is the space in which living organisms interact with their environment, affecting their survival and evolution. Not only do physical aspects of this environment matter, but it also contains both biotic and abiotic elements which are essential for development and health of organisms.
Environments can be divided into three categories: natural, constructed and managed. Of these three, the natural environment is the most critical as it contains all of Earth’s elements that make up its makeup.
Nature provides humankind with abundant renewable resources. These include plants and animals that can provide us with food, shelter and energy – which can be harvested using various techniques such as farming or harvesting.
However, over time these natural resources may become polluted with chemicals, waste and other pollutants which could negatively impact both the environment and people’s health. Therefore, people need to become familiar with their environment and take responsibility for its preservation.
Environmental education and awareness are effective tools in combatting climate change. They educate students on the detrimental effects humans are wreaking upon our planet, as well as teaching them how to minimize or even avoid these issues.
Ecosystems are composed of all organisms within an area and their interactions. This type of environment is dynamic, constantly adapting to changes in conditions.
Some ecosystems are more resilient than others. For instance, some rainforests seem to be less vulnerable to climate change effects than others, while deserts tend to be more vulnerable to drought conditions.
Climate change poses a serious threat to ecosystems, leading to the demise of many. It is also increasing pests and diseases that wreak havoc in forests – essential for wildlife survival – while devasting wetlands that support migratory birds in Midwest regions and beyond.
Climate change is expected to cause havoc on ecosystems in the future, such as melting ice sheets and permafrost, as well as changes to rainfall amounts. Furthermore, sea levels could rise significantly and dry land, impacting agriculture and decreasing water resources.
Humans are a major cause of climate change through the burning of fossil fuels like coal and oil. Since pre-industrial times, this activity has caused Earth’s temperature to rise by 1.1 degrees Celsius; scientists predict it will reach 4 degrees by 2100 if we do not address this issue.
