Sustainable living

  1. Sustainable living is a lifestyle that attempts to reduce an individual's or society's use of the Earth's natural resources and personal resources.

    Use less processed materials.

    I could not reach this

Fossils Fuels and Renewable

Fossil Fuels are things like petroleum or coal and they can't be replenished

Renewable energy sources can be used and reused.

Process to change waste materials into new products to prevent waste of potentially useful materials

People should recycle so the Earth doesn't go to waste in the relatively near future

Tin Can- 100 years

Glass Bottle- 500 years

Disposable Diaper- 75 years

Wood- 1-3 years

Paper- 2 to 4 weeks

Plastic Grocery Bag- 10-20 years

Styrofoam Cup- never

Aluminum Can- 80 years

Cotton T-shirt

Apple Core- 2 months

I was muchas surprised

Great garbage patch

The Great Pacific garbage patch, also described as the Pacific trash vortex, is a gyre of marine debris particles in the central North Pacific Ocean located roughly between 135°W to 155°W and 35°N and 42°N.

Here in Iowa we could volunteer to help or stop littering in general

Tundra and Rainforest

Tundra- Desert. Shrubs and Algae

Rainforest- River. Fish and Sea animals

Seawater biome



Sea urchins



Bullshark- carnviore

Omnivore- Whale

Scavenger- Seagulls

Dead Zones

They are hypoxic areas in the world's oceans and lakes that are cause by over-pollution

We can stop them by helping clean up and quit littering

Keystone species

A keystone species is a species that has a disproportionately large effect on its environment relative to its abundance.

A wolf would be a top predator.

There absence would create a misbalance in our ecosystems

Competitive exclusion

In ecology, the competitive exclusion principle, sometimes referred to as Gause's law of competitive exclusion or just Gause's law, is a proposition that states that two species competing for the same resource cannot coexist at constant population values

A shark and Alligator can't coexist



2 or more species living peacefully with each other

Lions and Tigers

Parasites- an organism that lives in or on another organism (its host) and benefits by deriving nutrients at the host's expense.

Mosquitos and Maggots

Mimicry- mimicry is a similarity of one species to another which protects one or both

Mutualism- Mutualism is the way two organisms of different species exist in a relationship in which each individual benefits from the activity of the other

Commensalism- an association between two organisms in which one benefits and the other derives neither benefit nor harm.

Carbon Cycle

The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth.

We affect it by use of fossil fuels and constant deforestation

Global Dimming

Global dimming is the gradual reduction in the amount of global direct irradiance at the Earth's surface

It is affected in Antarctica. It is a problem because it could eventually spread to other places.

Greenhouse effect

The greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases, and is re-radiated in all directions. It goes with the Carbon Cycle because it is also caused primarily by humans.

Endangered Species

An Endangered species is a species which has been categorized by the International Union for Conservation of Nature Red List as likely to become extinct, Tigers are endangered. It becomes endangered when there aren't limits on the hunting or the animals are poached. The ecosystem would suffer.

Invasive Species

An invasive species is a plant or animal that is not native to a specific location; and has a tendency to spread, which is believed to cause damage to the environment, human economy and/or human health.

Yellow Bass and Sharks. Yellow Bass kill other fish in lakes and Sharks don't belong in rivers but they sometimes get in them


We should care because eventually all of the forests will begone then we won't have as much lumber and medicines. Animals would lose their homes also.

Human population

Once we completely over populate, there won't be enough resources to continue our comfortable lifestyle. People will be fighting for food and water. The 3 basic essentials of life are food, water, and shelter


Pesticides are substances meant for attracting, seducing, and then destroying, or mitigating any pest. Famers need them but they overall have a bad effect on the environment.


If the things we take for granted just disappeared, we would not survive in a relatively short time


The Earth would be better because more smart cars are available and the cities would be a lot cleaner and safer.
