What is a renewable resource?

A resource that can replenish itself over time Examples include: solar power , wind energy, hydro-electiricty, geothermal, biomass

What is a non-renewable resource?

A resource that can't replenish itself over time Examples include: natural gas, coal, petroleum, and minerals

What is the difference between abiotic and biotic resources?

Biotic: derived from something that is living (this includes coal/natural gas) Abiotic: not derived from something living (ex: metals, solar power, wind energy)

The deterioration or loss of the productive capacity of the soils? (gradually gets less healthy)

Land degradation

Degradation of land caused by compaction, waterlogging, or subsidence?

Physical deterioration

The process by which fertile land becomes desert, typically as a result of a drought or inappropriate agriculture? (becomes dry)

Desertification

The removal of nutrient-rich topsoil by wind or water, causing the soil to lose nutrients and physical integrity? Many farming methods make soil vulnerable to this

Erosion

The loss of soil nutrients as a result of human intervention, especially pollution and the use of toxic pesticides?

Chemical Deterioration

When land is cleared for timber or, more usually, for agricultural use, the soil is exposed to erosion?

Deforestation

Humans use what percentage of habitable land for farming?

45%

3 Agricultural problematic methods?

1. Deep tilling (mechanically breaking apart the soil, leading to erosion) 2. Monoculture (using land to grow a singular type of crop) 3. Chemical usage (herbicides/pesticide use can kill essential microorganisms in soil, which is detrimental to soil health)

3 Agricultural Solutions?

1. Crop Diversification (growing multiple crops in one area, increases soil health) 2. No-till farming (prevents soil erosion) 3. Waste recycling (Anaerobic digesters are machines that allow farmers to reuse waste products (like manure) and convert it into a nutrient-rich fertilizer that can improve soil health.)

What is Urban Sprawl?

The process where cities, towns, and villages expand into the surrounding environment, destroying natural habitats.

What is a Green City?

An urban center designed to reduce its environmental impact while making life good for its citizens. Strategies include: Walkability/Public Transit Urban Greening Waste Management
