Droughts can occur due to either natural or human-induced factors. Droughts aren’t a type of natural disaster that is physically destructive. This kind of disaster does more economical damage than anything. Environmental things like climate change, ocean temperatures, changes in the jet stream, and changes in the local landscape all make a difference when it comes to droughts. Droughts can be very dangerous for people living in areas with not enough food or water. Droughts are the type of disaster that involves below-average precipitation and water supply shortage over long periods of time. Droughts often lead to the extreme scarcity of food and have led to the death of millions of people. The reason why lower levels of precipitation aid the occurrence of drought is because little to no rain means that the soil will dry out and that will eventually lead to crop failure. When crops fail, there isn't enough food to go around. It also means that farmers lose money, and the area can become very poor. When a region is very poor and doesn't have enough food or water, arguments can happen over who should be able to access the goods, which can escalate into wars. Identify ways in which humans have altered and continue to alter our environment. For decades and still to this day human have been creating cars and running factories that do nothing to our environment but destroy. We cut trees down not realizing their worth and the globe is heating up. Now we are closer to the end then we ever have been and it need to come to an end. Define sustainability and explain how it can be measured using the ecological footprint. Sustainability is basically being able to avoid depletion of the planet. It can measures by the impact of a person or community on the environment, expressed as the amount of land required to sustain their use of natural resources. Define systems within the context of environmental science. The atmosphere is the system that houses cloud and oxygen. All precipitation comes from the atmosphere. The biosphere is the system where all life is and oxygen is produced. Plant life also absorbs c02 The geo sphere is basically the mountainous area The hydrosphere is the system that is basically bodies of water. Earthquakes tend to happen in this system which end up causing tsunamis Distinguish between various forms of energy and discuss the 1st and 2nd laws of thermodynamics. The first law says that energy can be neither created or destroyed in an isolated area. The second law says that energy in an isolated area increases. Describe the ways in which ecological systems depend on energy inputs. The biosphere needs rain from atmosphere to keep life alive. The atmosphere needs the biosphere for oxygen production. The atmosphere needs the hydrosphere for evaporation of water. The biosphere needs to geosphere to create new land. Explain how scientists keep track of inputs, outputs, and changes to complex systems. Scientist in this day have satellites and all kinds of technology that allows to predict any kind of change in our systems. They are always keeping an eyes on it and most of the time they know what will happen before it happens. Describe how natural systems change over time and space. Over time humans just will continue to destroy the environment so it will only get worse. Since the ozone is depleting, it just allows more radiation from the sun and more natural disaster to occur. When I Did research on the information that I found to answer my essential questions, I wasn’t surprised at all. With all this climate change stuff going around, it’s kinda hard to not be informed on everything that is going on in our planet. I still do however believe that their is something we could do about climate change but there isn’t enough people who care to make the difference.
