Living

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. Practitioners of sustainable living often attempt to reduce their carbon footprint by altering methods of transportation, energy consumption, and diet.

Somebody can achieve stainable living by riding bikes to work or even walking and change what they use to cook. I do not think that we will ever get to sustainable living because they keep making cars and they keep making things with plastic.

Energy

Fossil fuels- a natural fuel such as coal or gas, formed in the geological past from the remains of living organisms.

Renewable energy- is energy that can be uses again. such as fresh water, oxygen, solar energy, timber, and biomass these two thing are way different. we will eventually run out of fossil fuels

fossil fuels are currently at about 85% of all all the energy. Renewable energy are much lower environmental impact then fossil fuels. Technologies that utilize the, are often called "green" you should us renewable energy so we can use the fossil fuels when we really need them. Would you want to be the reason we run out?

Recycling

Recycling means to convert waste into reusable material. Why should people recycle? because it will help the world and we wont end sooner. lol.

Tin can- do not decompose they just rust.

Glass bottles- approximately one million years.

Disposable diapers- about 500 years.

Wood- 10 years to fully decompose.

Paper- News papers take about six weeks to decompose.

Plastic grocery bag- 1,000 years

Styrofoam cup- about 100 years

Aluminum can- takes up to 500 years.

Cotton T-shirt- 2.5 years.

Apple Core- 2 months.

Did any of these surprise me? Yes they all did . I thought once you throw it out it'd be gone in a week or so.. but guess not.

Biomes

Some Biomes are Arctic Tundra and Coniferous Forest.

Arctic Tundra- is extremely cold climate, low precipitation, surface drainage only, small number of wildlife and plant species, short growing season and reproduction, limited supply of nutrients, and large variation in populations. Arctic Tundra is found in Alaska, Greenland, Canada, Europe and Siberia. No deep-rooted vegetation exists because of permafrost (permanently frozen ground). There is as much as two months of darkness and even in the summer the sun is close to the horizon that there is a low intensity of sunlight. Some Abiotic factor are strong winds, little rainfall, short summer days, long cold winters, poor soil. Some Biotic factors are plants like heaths and mosses have to adapt to very long and cold winter because the sun does not come up in the winter. Wildlife like arctic tundra animals include snowy owls, reindeer, polar bears, white foxes, lemming, arctic hares, wolverines, caribou, migrating birds, mosquitoes and black flies.

Coniferous Forest- stretches in great belt around the Northern Hemisphere and from Alaska, Canada, the USA, Scandinavia and Siberian Russia. A few tree species exist which are mainly conifers such as Pine, Spruce, Fir and larch. Some abiotic factors are mild, moist air from the pacific oceans. durning the summer, it is cool and dry and during the winter, it is extremely cold. this biome receives abundant rainfall during the fall, winter, and spring. the soil is very rocky and acidic. The soil also is generally thin and it is poorly drained. Rain about 20 inches per year. Some biotic factor are white tailed deer, reeves muntjac, fox, mice, owls and squirrels. There are many plants in this biome, but three are more dominate than others. These are pine, fur, cedar, and spruce tress. Mosses are also found almost anywhere here.

Food Chain

Food chain of the desert- First you start with your primary producers.- are organisms in an ecosystem that produce biomass from inorganic compounds. {Autotrophs} cacti, sage brush, ocotillo, rabbit brush and much more. Then you move up to your primary consumers {plant eaters} - organisms that eat the autotrophs; these organisms are called herbivores. insects, lizards, rodents. Then you move up to your carnivores {Small predators, Insectivores} - an animal that feeds on flesh. Tarantulas, scorpions, larger lizards, snakes. Then you got your larger predators. - {These eat everything} Hawk, fox.

Great Pacific Garbage Patch

- is garbage in the north pacific ocean. We can help in Iowa by having more people throw there things away and not just throwing it on the ground.

The name "Pacific Garbage Patch" has led many to believe that this area is a large and continuous patch of easily visible marine debris items such as bottles and other litter—akin to a literal island of trash that should be visible with satellite or aerial photographs. This is not the case. While higher concentrations of litter items can be found in this area, much of the debris is actually small pieces of floating plastic that are not immediately evident to the naked eye.

Dead Zones in the Gulf of Mexico the hypoxic zone in the northern Gulf of Mexico is an area along the Louisiana-Texas coast, where water near the bottom of the gulf contains less than 2 parts per million of dissolved oxygen, causing a condition referred to A HYPOXIA. The only way to stopping it is be safe of what you drink. and watch what water holes you are using out of.

Keystone Species

Are a species on which other species in an ecosystem largely depend, such that if it were removed the ecosystem would change drastically. Wolves- being a top predator, wolves are important in many habitats. Wolves keep deer populations in check and too many deer will eat small tress, which leads to fewer tress. in turn, there would be fewer birds and beavers and the whole ecosystem would change. Snow geese- of there are not enough geese in salt marshes, other harmful species will take over. when the geese graze, it leaves open areas for other varieties of plants to take root, thus adding to the diversity of the habitat.

Competitive Exclusion

The inevitable elimination from a habitat of one of two different species with identical needs for resources. The red squirrel and the grey squirrel.

Terms- Coexistence- the awareness that individuals and groups differ in numerous ways including class, ethnicity, religion, gender, and political inclination. These group identities may be the causes of conflicts, contribute to the cause of conflicts, or may be solidified as conflicts develop and escalate.

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

Mimicry- The action or art of imitating someone or something, typically in order to entertain or ridicule.

Mutualism- the doctrine that mutual dependence is necessary to social well-being.

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

Carbon Cycle is the series of processes by which carbon compounds are interconverted in the environment, chiefly involving the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels humans activities are substantially modifying the global carbon and nitrogen cycle. the global carbon cycle is being modified principally by the burning of fossil fuels, and also by deforestation.

12.

Global Dimming is tiny particles that are released when fuels are burned cause global dimming. Shows in places where global warming is up. It stops some rainfall.

13.

Greenhouse Effect is the trapping of the suns warmth in a planets lower atmosphere due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planets surface. Carbon cycle and the Greenhouse effect go together because after so long of the warmth sitting under the earth for so long it turns into carbon cycle.

Endangered Species are animals that have little to no animals in the group. Pandas are endangered. Animals become Speciesndangered because humans hunt them for there skins or their meat. Another way they are killed is when their area they live in is taken away for humans to build in it. If these animals were keystone animals the ecosystem would fall greatly because everything will be out of order. Humans should care about endangered animals because I feel like we should care because the ecosystem is going to fall and when that’s gone and the animals are gone there’s no getting it back.

Invasive Species

Invasive species is an invasive species is defined as an organism that is not native and has negative effects on our economy, our environment, or our health. Not all introduced species are invasive. Invasive plants and animals are the second greatest threat to biodiversity after habitat loss. Red deer and wild pigs. Also known as wild or feral hogs , pigs, or boars once roamed European and Asian hillsides. The purebred pigs have now gone extinct in much of their native range, but they have spread to other parts of the world including New Zealand, Australia, Latin America and North America prized for its "medicinal'' properties in parts of Asia and as a trophy species by South American hunter, the red deer has spread from its native Eurasia to the Americas, New Zealand and Australia, These deer’s aren't picky when it comes to choosing a home. These animals have spread from their Native homes because human population.

Rain Forest

People should be worried because the animals coming from the rain forest are coming to new towns and hurting and damaging people and their properties. Rain forest are being cut down to extend large city's and to make new city's. If all the rainforest disappear then all the population of unique animals and plants would go extent and we will never get any of it back.

Overpopulation of Humans

There is a huge concern of overpopulation in humans about the balance between human needs and the resources available to meet those needs, now, and for the foreseeable future. The major problem is resources are declining rapidly. Includes air, water, food, shelter, sanitation, touch, sleep and personal space.

Pesticides are a substance used for destroying insects or other organisms harmful to cultivated plants or to animals. They effect the environment because they kill animals and plants. It creates problems with the genetic diversity in crop production because some bugs have became used to it and stay alive and eats the plants and cause diseases in them.

19.

Bees "if the bee disappeared off the face of the Earth, man would only have 4 years left to live" this means that pollination would not happen and there would be no pollen to pass to other flowers so plants would not be able to grow and man would not have the veggies to fruit to eat and the earth will soon die away.

Grand children "When I was younger there was monkeys and there was big trees and woodland. Me and my sister used to get lost into the woods and now they don't even have trees you can climb. Now kids do not go outside and stay inside and when they go outside they throw things on the ground and they trash everything, today’s earth is brown and dirty there isn't even ponds you can go swim at."
