Human Consumption

Humans are regularly consuming natural resources. Consumption refers to the use of resources. When consumption becomes too high, resources can become scarce and difficult to obtain. Because many daily activities require natural resources, such as fossil fuels for generating electricity, resource consumption is vital to manage.

Most everyday activities require some form of resources. Natural resources are necessary for most individuals, whether it is the food you eat, the fuel to power vehicles, or the electricity you use. However, the use of these resources can have substantial impacts on Earth's systems.

Impact: Water pollution can add excess nutrients, harmful chemicals, or disease-causing organisms to water supplies.

Water Pollution

Standard processes involved in developing everyday products and food supplies can impact local water quality. Industrial waste and runoff from agriculture can cause water pollution.

Consequences: Contamination of drinking water can lead to diseases with both short and long-term health effects on humans. Water pollution can harm ecosystems by affecting plants and wildlife.

Impacts: Burning fossil fuels produces gases, such as carbon dioxide, that enter the atmosphere and are breathed by organisms and mixed with water vapor.

Air Pollution

The burning of fossil fuels results in air pollution. Vehicles are a common source of air pollution. However, air pollution is also a common side effect of many industrial processes.

Consequences: Air pollution impacts the respiratory system of many animals and has been connected to heart disease and cancer. Carbon dioxide contributes to acid rain which damages plants.

Impacts: Land space is required for landfills. Also, landfills require proper maintenance and risk possible soil and water contamination. Recycling helps reduce the need for new resources but also requires additional energy consumption.

Waste Disposal

Using resources and products made from natural resources often results in waste. Waste may be disposed of in various ways, including placing it in landfills or sending it to recycling centers.

Consequences: Groundwater contamination from landfills can lead to water pollution in local environments. Soil contamination can harm local vegetation.

As you can imagine, the impacts of resource consumption often increase as the demand for resources increases. As more resources are desired, the pressure to more quickly and affordably obtain those resources can lead to conditions that will worsen the impacts of resource extraction and processing.

Increasing Demands = Increasing Impacts

Consider the following scenario: A farmer wants to increase crop production to meet a growing demand for more food. To ensure a greater crop yield, the farmer uses pesticides to reduce plant loss from insects. The farm is located near a river.Which impact would most likely result from the farmer's actions?Click the question mark to answer!

An increased risk of air pollution from the pesticides used on the field

An increased risk of water pollution from agricultural runoff

An increased risk of soil contamination as there will be more crops

Efficiency

Technologies that improve energy efficiency help reduce the need for nonrenewable resources. Increasing energy efficiency also helps reduce overall costs associated with using fossil fuels. For example, better insulation allows less fuel to be used for heating.

Cogeneration

Fossil fuels are commonly burned to boil water for steam to generate electricity. It is more beneficial to find multiple ways to use that hot water, such as for creating electricity and as a heat source.

Conservation

Strategies to Meet Demand

Finding alternative strategies for resource use helps protect and conserve limited supplies of nonrenewable resources. For example, recycling metals helps provide a source of materials that does not require extracting raw materials from the Earth, saving fuel.

Since most of our commonly used resources are nonrenewable, meeting the demand for these resources requires efficiency and conservation

apply scientific principles to propose solutions for reducing the negative effects of technology on the environment

explain the importance of assessing and minimizing the environmental impact of technology

Objectives For The Next 2 Stations

describe how technology can both positively and negatively impact the environment

It is almost impossible to imagine a world without technology, especially in our school!Technology refers to using science to make products that improve human life. It can apply to the product itself, such as a computer, a tool, or a vehicle. It may also be applied to new strategies or methods developed using scientific principles. Technology has dramatically changed throughout human history, but there have been significant advancements in technology over the last few decades.Click the image of the computers to see how our technology has improved over time.

Technology

Reflect on the technology in your life:

POSITIVE IMPACTS

You may already be aware of the many benefits that come with technology. The availability of technology enhances the ability to connect with others, be entertained, and learn. While these are direct benefits to the individuals using the technology, there are also many advantages that technology can provide to Earth systems.

Weather radar technology has provided methods for scientists to monitor and track weather and climate conditions. This monitoring helps them prepare for severe weather hazards. It also provides a way to better understand humans' impact on Earth's climates.

Advancements in technology have provided the means to develop alternative energy sources. For example, solar farms offer a means to generate electricity that is less harmful to the environment than traditional fossil fuels.

More advanced computer systems allow for more control and efficiency when utilizing natural resources. These technicians use various information to ensure that the natural gas powerplant makes the most of the nonrenewable resource.

NEGATIVE IMPACTS

Despite the many benefits of technology use, some drawbacks exist. One of the most prominent examples of a disadvantage is the waste. As new technologies emerge, there is often a transitional time where older materials are discarded and replaced with more modern options. Consider how often companies encourage the purchase of the latest phones and computers. These products are usually made with plastics that, if not properly recycled, can result in pollution that lasts a long time.

The technologies humans use, and their impacts, can have lasting effects on the planet. Click the video below, type your name, and watch about the lasting results of humans. As you watch the video, consider how using technologies and developing materials may dramatically impact Earth, even into the distant future.

TRANSITION TO SUSTAINABLE ENERGY

Scientists recognize that it is crucial to prioritize the development and widespread adoption of renewable energy sources

FUTURE TECHNOLOGY

Agriculture is one example of a field impacted by new and improved technologies. Despite humans practicing agriculture for thousands of years, technological advancements over just the past hundred years have dramatically altered what modern agriculture looks like.

Agricultural Technology

Early Agriculture

primarily done by hand
relied on simple tools
benefited from the development of simple machines, such as the wheel
domesticated animals such as oxen and horses
focused on growing food primarily for their families.

Modern Agriculture

due to the development of the engine and motorized vehicles, tractors are common - changed how efficiently a farmer could manage their fields
modern technologies, such as computers, provide methods for tracking data and managing complex planting and harvesting schedules - farmers can now grow more crops

Technology also provides a means to meet the growing demand for human resource consumption. For example, there is a considerable need for more food as Earth's global population increases. Technology allows for more efficient and greater crop yields. Farmers have access to real-time weather information as well as farm equipment to ensure that they are able to produce more than would have previously been possible.

Technology Benefits in Agriculture

In some instances, technology that was once seen as beneficial is revealed to have dramatically harmful impacts. The danger of using chemical pesticides was not fully understood until the 1970s, when connections were made to pesticide use and severe medical conditions in humans and wildlife.

Technology Disadvantages in Agriculture

Fertilizers, especially chemical fertilizers, are a commonly used tool for increasing crop yield. However, excess fertilizer is often washed into local waterways when it rains. The nutrients then feed algae in the ponds, lakes, and streams. The additional nutrients result in an increase in algae. The emergence of all of the new algae affects water quality. It can be harmful to other aquatic organisms, such as fish.

Technology Disadvantages in Agriculture

Psychologist Abraham Maslow developed the concept of the hierarchy of needs in the mid-1900s. According to this organization, the most basic needs are physiological, such as the need for food, water, and shelter.Someone may say they "need" something, like the latest phone or a new video game, but these are considered desires. This is because those items are not required for survival.

Needs

Needs Vs. Desires

Desires are what make humans unique from different organisms
When basic needs are met, an individual is often more comfortable pursuing specific desires related to those needs.
For example, when you are hungry, you may wish to have a hamburger or a salad. While either of these foods meets a necessity, the ability to choose based on taste preference is related to desires.

While some materials and resources are necessary to meet basic survival needs, products that are desired rather than needed account for some of the most significant environmental impacts.

Wood is a critical resource for buildings and construction. As the population grows, there is an increased need for housing. However, the desire for bigger homes and properties contributes to forest clearing, causing deforestation. Deforestation reduces biodiversity and contributes to climate change.

Deforestation

In many areas, transportation is a necessity. Most forms of transportation require fossil fuels. Burning fossil fuels results in harmful air pollution. Smaller, more fuel-efficient cars, carpooling, or public transportation help reduce this impact. However, this is balanced against the desire for larger, personally-owned vehicles.

Air Pollution

Individually packaged food and drink containers are often convenient to use. However, the widespread use of these single-use products contributes to increasing plastic pollution. Plastics do not readily break down and stay in the environment for hundreds of years.

Plastic Pollution

Let's Reflect

Great job! The code letter #7 is R. Write it down!

Scientists identify the problem- examples: limited availability of specific resources or the efficiency with which resources are being used

What Do Scientists Do?

Scientists recognize that resource availability, technology impacts, and growing desires are concerns and work to develop solutions to address the issues.

Scientists develop strategies- examples: may involve exploring alternative renewable energy sources or the development of technology to improve resource use efficiency

Scientists evaluate impacts- examples: renewable energy is an excellent alternative to traditional fossil fuels. However, costs often make these resources more inaccessible, requiring exploring options to make these resources more accessible.

When exploring the prevalence of products in countries like the United States, it is crucial to consider the environmental impacts and develop strategies to mitigate the adverse effects. Here are some examples!
