The Four Laws of Ecology Formulated by physicist and ecologist, Barry Commoner. Source:
1 st Law: Everything is connected to everything else Humans and other species are connected (dependent) on a number of other species.
1 st Law: Everything is connected to everything else Making connections: 1.What is the connection between the rise of McDonalds outlets in China and the massive deforestation in the Amazon forest in Brazil. 2. Take the Carbon footprint test:
2 nd Law: Everything must go somewhere For example, when you burn wood, it doesn't disappear, it turns into smoke which rises into the air, and ash, which falls back down to the earth. No matter what you do, and no matter what you use, it has to go somewhere.
3 rd Law: Nature knows best Read your article and write examples for Law #3: Mothers milk vs. milk formula Real food vs. vitamins Pesticides vs. natural enemies: Wild (or prescribed) fires vs. stopping fires
Nature knows best: How the natural world is inspiring new innovations When we look at the world around us, we see what has survived the test of time. In other words, nature doesn't just show us results - it shows us the most optimal ideas available. As a result, scientists are creating more products that are inspired by nature. The BlackBerry phone was inspired by a butterfly's wing.
Nature-inspired designs Bio-inspiration, also known as biomimicry, is a discipline that studies and learns from nature's best ideas to generate breakthrough products and technologies. Solar Leaf

4 th Law: There is no such thing as a free lunch This law basically means you have to do something in order to get something in return. OR Everything has consequences. Everything you do, must have a reason behind it. For example, a free pizza party. In order to win the party, you have to fill out a survey. Survey info gets sold off… you get annoying texts from companies ….
There is no such thing as a free lunch Because the global ecosystem is a connected whole, in which nothing can be gained or lost, This ecological law embodies the previous 3 laws. Payment of this price cannot be avoided; it can only be delayed. anything extracted from it by human effort must be replaced.
EXAMPLE #1: Tall smokestacks Tall stacks were originally designed to take local pollutants that resulted from manufacturing processes and put them just high enough into the atmosphere that they would be dispersed away from the local area. The phrase used at the time to describe this process was The solution to pollution is dilution.
EXAMPLE: Tall smokestacks Over time, however, people in downwind locations complained that they were the victims of pollutants from elsewhere and they reacted politically to have the process stopped. Hence, there was a call for the enforcement of a polluter pays principle: those causing the harm from pollution to others must pay for the cleanup and removal of the pollutants and the repair of their adverse impacts on the built as well as natural environment.
EXAMPLES: Things may seem free, but have hidden costs. HOW? Oil comes shooting out of the ground. Free phones with a 3 year plan. Oil comes shooting out of the ground. Free phones with a 3 year plan. Free samples at grocery stores. Love. Admiration. Respect.
EXAMPLE #2: OIL Oil comes shooting out of the ground. It seems free, but it costs us. HOW?
Hidden Costs Other examples: Free phones with a 3 year plan. Free samples at grocery stores. Love. Admiration. Respect. Things may seem free, but have hidden costs.
