Study Notes
Sustainable Practices
- Wind farms are considered a sustainable energy source, harnessing wind power with minimal environmental impact.
- Practices such as clear cutting, flood irrigation, and overfishing are not sustainable as they can lead to ecological imbalances and resource depletion.
Invasive Species
- Invasive species negatively impact native ecosystems by threatening biodiversity and disrupting food webs.
- They may also become dominant predators, outcompeting native species but do not specifically contribute to environmental pollution in the way often assumed.
Reducing Air Pollution
- Using a bike instead of a car is an effective way to decrease air pollution and reduce carbon emissions, promoting sustainable transportation.
- Alternatives like dumps and coal usage do not contribute to cleaner air, while wind farms represent a clean energy source.
Greenhouse Effect
- The greenhouse effect is a natural process vital for maintaining Earth’s temperature, resulting from greenhouse gases trapping heat in the atmosphere.
- It is essential to differentiate this natural process from artificial or dangerous interpretations.
Types of Pollution
- Air pollution includes harmful substances like chlorofluorocarbons (CFCs) and smog, which can significantly impact health and the environment.
- Water and land pollution refer to different contaminants and sources of ecological damage.
Fossil Fuels
- Fully fossilized fuels include natural gas, coal, and oil, which are not renewable and contribute to climate change when burned.
- Other options mentioned, like wood and solar energy, do not fit the category of fossil fuels.
Sustainable Use Practices
- Sustainable use practices involve managing natural resources to prevent depletion rather than degrading the environment.
- These practices encompass environmentally friendly consumption and conservation tactics rather than merely deploying fossil fuels.
Greenhouse Gases
- Carbon dioxide and methane are significant contributors to the greenhouse effect due to their heat-trapping properties.
- Nitrogen and helium do not contribute to this effect and are not considered greenhouse gases.
Freshwater Resources
- Although freshwater is theoretically renewable, environmentalists often classify it as nonrenewable due to risks of pollution, overuse, and depletion.
- The contradiction arises because human activities can hinder the natural replenishment cycle of freshwater sources.
Nonrenewable Resources
- Coal is a primary example of a nonrenewable resource, meaning it cannot be replenished within a human lifetime once depleted.
- In contrast, soil, fish, and wood are generally considered renewable resources under sustainable management practices.
