Environmental science study of how our natural world works, how our environment affects us and how we affect the environment. Natural resources: various substances and energy sources we need to survive. Renewable: natural resources which are replenishable over time sunlight, wind, wave energy. Some resources such as agricultural crops, fresh water, forest products and soils are renewable if used properly if over-used then they become nonrenewable resources. Resource management: planning on how to use a resource in such a way that we are still protecting and preserving it. Stock is the harvestable portion of the resource if resources are being withdrawn from the stock at higher rates than it is being replenished, then the stock will eventually be depleted. Non-renewable : in finite supply and are depleatable fossil fuels, mineral deposits, natural gas etc.
