Environmental Studies

Measuring tree diameters is typically associated with Ecology, focusing on understanding ecosystem dynamics.

Components of the Environment

The environment comprises various elements including:
- Plants and animals in the natural world.
- Nonliving portions like soil and water.
- Humans and man-made structures.
Collectively, this means the environment includes all of the above.

Renewable vs. Nonrenewable Resources

Nonrenewable resources include substances that do not replenish quickly, such as:
- Natural gas.
Renewable resources can regenerate over time and include:
- Freshwater and soil.
- Sunlight, which is abundant and sustainable.

Sustainable Resource Usage

A resource that is used at the same rate it replenishes is referred to as a sustainable resource.

Ecological Footprints

Nations with the largest ecological footprints typically:
- Have substantial fossil fuel consumption.
- Do not necessarily correlate with having the highest natural resources or the most environmental laws.

Groundwater Depletion Impacts

As groundwater resources are depleted:
- Crop prices irrigated by this water are likely to increase due to reduced supply.

Farmer Decision-Making

Decisions farmers face regarding staying in farming vs. changing careers often rely on:
- A cost-benefit analysis.

Early Environmental Policies

Early environmental policies in the U.S. primarily involved government regulations rather than incentives or tax breaks.

Cap-and-Trade Policies

The Cap-and-Trade policy involves:
- Setting limits on greenhouse gas emissions with the ability to sell permits if targets are not met.

Ecosystem Services

Going kayaking exemplifies a cultural ecosystem service, highlighting recreation and enjoyment of nature.
Wetlands prevent flooding through their ability to absorb excess water, representing a regulating ecosystem service.
