SUSTAINABILITY OF NATURAL RESOURCES
Green House Effect
Without greenhouse gasses earth would be too cold for life
Too much greenhouse gasses makes the earth too hot.
Greenhouse gasses such as CO2, warms the Earth.
Humans are causing more greenhouse gasses
The greenhouse effect is the warming of the earth
Burning fossil fuels and cows producing methane can be reduced by humans.
Humans and their Environment
For the last 200 years humans destroyed their envoronment.
During the industrial revolution there were more people that caused more pollution.
Three ways to help the environment
Cleaning up
Chiming in
Conserving
Using nonrenewable causes polution and will eventually run out.
Air Polution
Fossil fuels release deadly gasses, like carbon dioxide and sulfur dioxide which can make people sick.
Greenhouse gasses contribute to global warming.
Fossil Fuels such as coal, gas and oil release particles of soot and dust when burnt.
Smog
Soot+Fog
Not good to breath
Air pollution comes from a lot of different sources.
Soil
Plants need rocks and humus to grow.
Soil has different layers and topsoil has the most humus.
Erosion moves sediments.
Weathering breaks rocks into small pieces called sediment.
Soil is a mix of rock water and dead stuff
Climate Change
Global Warming is about the average temp. of the earth.
Climate change is happening naturally but humans are making it happen faster.
Climate change is cause d by greenhouse gasses which trap the heat
Burning coal makes more CO2
Trees remove CO2 so we need more trees.
Global warming can lead to bad weather and diseases but we can solve the problem.
Natural Reasources
Anything that people value.
We use energy resources to power our cities.
Has to occur naturally in nature.
Types of natural resources
Non-Renuable
Coal
Oil
Minerals
Renuable
The sun
Fish
Forest
REDUCE REUSE RECYCLE!!!
Population Growth
Earth can support a cerain amount of people
Humans can reduce their use to help with concervation.
In 10 yrs population will be more than 8 billion people.
More humans on earth=more pollution and using resources faster.
200yrs ago the homo-sapiens population boomed
