What is a Renewable Resource?

: A natural resource that nature can replace or replenish in a short period of time (from seconds/days up to a human lifetime, like a few years or decades), such as solar energy, wind, water, and trees.

What is a Nonrenewable Resource?

A natural resource that exists in fixed amounts and takes millions of years to form (geological time scales far beyond a human life), meaning once we use it up, it is gone for good (e.g., fossil fuels, minerals).

What is "The Tragedy of the Commons"?

What is Qualitative Data?

What is Quantitative Data?

: Numerical data that can be measured or counted (e.g., temperature, weight, population size).

Ecosystem services

are the direct and indirect benefits that humans get from healthy, functioning natural systems.Water purification, pollination of crops, climate regulation, and nutrient cycling

ecological foot print

is a measure of the demand made by one person or a groupnon global natural resorce

peer reeviw

Peer review in science is a quality-control process where experts in the same field evaluate a research manuscript or grant proposal before it is published or funded

importance of peer reeviw

it acts as an independent quality filter that checks the validity, accuracy, and credibility of scholarly research before it reaches the public.

Economic influences in environmental decision-making

turning ecological protection and natural resources into financial values, trade-offs, and market metrics. [1, 2]Only do decisions makers Need to think about the cost of the resource but also whether is it worth, what is gained.

This process of decision making is called cost benefit análysis

was a brave scientist and writer who wrote the 1962 book Silent Spring to expose how chemical pesticides were poisoning the environment.

Her work led to a ban on dangerous chemicals like DDT and created the EPA, launching the modern environmental movement.
