LT: Today I can apply scientific concepts to understand environmental issues by analyzing the author’s purpose in diagrams. What are natural resources and what is the difference between renewable and non-renewable resources?

Natural Resource- Materials removed from the Earth and used by people to satisfy needs and wants.

All resources are put into one of two categories: Non-Renewable Renewable Nonrenewable Resource- a resource that cannot be remade or re-grown at a scale comparable to its consumption (use). ie. It’s used faster than it can be remade. Renewable Resource- a resource that can be replenished in a short period of time.

Nonrenewable Resources Examples of how it is used Fossil Fuels Energy for Homes Cars Factories Nuclear energy Uranium is used Is used for energy for Minerals Ex) Copper Gold Iron are used to make goods

Renewable Resources Resource Examples of how it is used Solar Hydro Heat energy for the Sun can be converted and used for Homes Cars Factories Hydro (water) The mechanical energy from water can be converted and used for energy for Wind The mechanical energy from wind can be converted and used for energy for

Examples of how it is used Resource Examples of how it is used Geothermal Heat energy for the Earth can be converted and used for Homes Cars Factories Biomass Organic (living) matter can be burned like fossil fuels for the energy can be used for

Air Pollution Source Chemicals/ damage Impact Carbon dioxide (CO²), Sulfur dioxide, Nitrogen oxides Methane Acid rain Ozone depletion Global warming Health issues to humans and other organisms

Air Pollution

Water Pollution Sources Chemicals /damage Impact Fertilizers Pesticides Toxic chemicals (metals, mercury, lead, etc.) Fertilizers increase growth of green plants such as algae and breathable oxygen is less available for other organisms. Chemicals from pesticides and other agents damage cells of living things.

Water Pollution

Water Pollution

How do pesticides and fertilizers from farms and lawns, and oil and gas from parking lots and streets get into the water sources? Runoff- most land is above sea level. Water runs from the land to the water sources

Land (Soil) Pollution Sources Chemicals /damage Impact Soil erosion and depletion Toxic chemicals (metals, mercury, lead, etc.) Soil erosion (movement) and depletion reduces the ability of producers to grow Chemicals from pesticides and other agents damage cells of living things.

Part 3- Ecosystem Disruption Explain what it is How does it affect the organisms in an ecosystem? Habitat Destruction Organisms that live in the forest (and other areas) lose their homes due to the clearing of forests and woodland to make homes and buildings. It increases competition for food and space which results in reduced populations. Eventually leading to extinctions. Loss of Biodiversity Biodiversity is the various organisms within an ecosystem. Loss of biodiversity is the death of organisms and/or species. The loss of life in an ecosystem disrupts the balance of all lives within that ecosystem. Organisms rely on other organisms for food and population control. Invasive Species An organism that is introduced into an ecosystem that it is not a native to. This can disrupt the ecosystem because the non-native species will not have natural predators and its population can increase to the point that it creates an increase of competition for space and food. This competition can lead to the disruption and/or the extinction of other species.

What are some of the ways to reduce human impact on the environment What are some of the ways to reduce human impact on the environment? Conservation (protecting) and Restoration (cleaning up and restoring damaged habitats) Reduce -reduce the amount of energy used and waste produced Reuse – reuse goods Recycle- reusing natural resources by breaking them down and using them to create other goods

Technology- provides cleaner energy sources, better ways to deal with waste, and improved methods. Renewable resources- the burning of fossil fuels results in the release of the chemicals that lead to various types of pollution (ex) acid rain, ozone depletion, global warming, etc. Environmental Awareness- Advocacy- people who fight for a solution. Education- education leads to public support and advocacy. Planning for the Future- Planning for future generations can help avoid damage to the environment and help us solve environmental issues.
