Students will demonstrate this knowledge by create a presentation illustrating the effects of human activities on water resources. More humans consume more freshwater more land more clothing etc.

Changes to our water resources affect many sectors including energy production infrastructure human health agriculture and ecosystems.
. The source document for this Digest states. Changes in land use brought about by agriculture and urbanization. Pesticide A chemical intended to kill insects and other organisms that damage crops.
Then they will use that same river ocean to shower wash clothes the animals will drink that same water - so does some people. The right bar shows the breakdown of surface freshwater. Generally speaking as the human population grows our consumption of natural resources increases.
Changes will vary in different regions of the United States. In this lesson students will learn about the human demands of freshwater and how clean drinking water is being impacted. Looked at another way only one percent of the water on the Earths surface is usable by humans and 99 of the.
Freshwater on the land surface is a vital part of the water cycle for everyday human life. Generally speaking as the human population grows our consumption of natural resources increases. Destructive land use practices that result in vegetation loss can have negative impacts on freshwater ecosystems.
Of freshwater 69 resides in glaciers 30 underground and less than 1 is located in lakes rivers and swamps. Availability of freshwater is vital to live on Earth yet freshwater makes up a tiny fraction of all the water available on the planet. The distribution of water on the Earths surface is extremely uneven.
Of all of the water on Earth 97 is saltwater leaving a mere 3 as freshwater approximately 1 of which is readily available for our use. Resource distribution refers to the geographic occurrence or spatial arrangement of resources on earth. Only 3 of water on the surface is fresh.
They also contribute to the pollution worldwide which affects all areas including rainforests. Humans affect the water resources of virtually all landscapes some of the most relevant structures and features related to human activities are super-imposed on various parts of the conceptual land-scape Figure 25. In the poor country youll see people throwing trash in the water.
Water is the fundamental ingredient for life on Earth. Low latitudes latitudes close to the equator receive more of the suns energy and much precipitation while higher latitudes. Most of this water is locked up in ice and another 209 is found in lakes.
Any particular place may be rich in the resources people desire and poor in others. The introduction of chemical physical or biological agents into water that degrade water quality and adversely affect the organisms that depend on the water. Human Impacts on Freshwater Resources STUDY PLAY Algal bloom The rapid growth of a population of algae Microcystin HEPATOTOXINS Toxin poison Fertilizer a chemical that provides nutrients to help crops grow better.
Uneven distribution of fresh water causes an Impact on the lives of people. They are called Natural Resources and are the basis of life on earth. For example when freshwater sources are contaminated by salt which can happen when ocean water surges into freshwater areas the consequences can be devastating for the crops livestock and people.
Wrong use of the land. Rivers make up 049 of surface freshwater. The effects of human activities on the quan-tity and quality of water resources are felt over a wide range of space and time scales.
Although rivers account for only a small amount of freshwater this is where humans get a large portion of their water from. Students will analyze the issues of cause and effect between human activities and water sustainability. Describe three ways that communities can increase their freshwater resources.
Humans affect rainforests whenever they take natural resources from them such as trees. We as humans impact the water resources in different ways. In other words where resources are located.
It causes the destruction of nature and depletion of a valuable resource. Many of these are primarily the result of human actions and include ecosystem and landscape changes sedimentation pollution over-abstraction and climate change. Wastes that people dispose of can pollute the air the land and water resources.
The removal destruction or impairment of natural ecosystems are among the greatest. Water Distribution on Earth. The forests and native plant communities surrounding lakes rivers and wetlands help protect water quality and quantity by filtering and storing runoff.
A number of forces continue to seriously affect our natural water resources. The causes of freshwater pollution are varied and include industrial wastes sewage runoff from farmland cities and factory effluents and the build-up of sediment. 1 Answer Gazza Mar 21 2018 Lot of ways.
You can find it in the atmosphere above us in the ocean rivers and lakes around us and in the rocks below us. Ever since the earth was inhabited humans and other life forms have depended on things that exist freely in nature to survive. Potential effects include increased flooding and drought water quality impairment and salt water intrusion to coastal water supplies.
These things include water seas and fresh water land soils rocks forests vegetation animals including fish fossil fuels and minerals. They affect the quality of rainwater and of water resources both above and below ground and damage natural systems. Even though fresh water is renewable there is not always enough of it in a given place at a given time.
The more people on the planet the more food you need to feed those humans more. Find out more about Earths water. You probably know that bacteria and chemical pollutants are bad news but thats not the only danger.
Although water covers about 70 percent of Earths surface only a small percent of that water is freshwater and even less of that is easily accessible to the billions of organisms. There are also political problems connected to the distribution of fresh water. On the landscape freshwater is stored in rivers lakes reservoirs and creeks and streams.
The remaining 97 resides in the ocean. Water ShortagesWater shortages occur when people use water faster than the water cycle can replace it. Human activities can also reduce water supplies in an area.
Uneven distribution of fresh water directly affects the distribution of the global population. Most of the water people use everyday comes from.
