SUSTAINABILITY OF NATURAL RESOURCES
Greenhouse effect
greenhouse effect is the warming of the earth
Greenhouse gases, such as CO2, traps heat on the Earth
without the greenhouse gases earth would be too cold to . live on
too much greenhouse makes the earth too hot (global warming
global warming causes problems such as floods storms diseases etc
humans are causing global warming by burning fossil fuels and raising lots of cows (methane)
Population Growth
earth can only hold a certain amount of people
about 200 years, there was a great increase in the number of people
more people causes more pollution and resources
in about 10 years there will be more than 8 billion people on earth
humans need to use more renewable resources
Natural resources
anything in nature that people value
plastic is not a natural resource
there are 2 types which are renewable and nonrenewable
reducing reusing recycling will conserve our resources
Climate change
global warming is about the temperature of the earth
the earths temperature is increasing faster than normal
Global warming is caused by more greenhouse gases
The gases trap the heat on the earth (greenhouse effect)
People using fossil fuels is producing more carbon dioxide
Trees remove some of the carbon dioxide
climate change is causing more bad weather and diseases but we can fix the problem by conserving our resources
Soil
soil is a mix of water rocks and dead stuff
weathering breaks rocks into small pieces called sediments
erosion moves the sediments to different places
rocks and humus help plants to grow
soil has different layers and topsoil has the most humus
plants cannot grow in bedrock, so we must protect the topsoil
Air Pollution
power plants, factories, furnaces and stoves all of these pollute the air
greenhouse gases contribute to global warming
smog contanis ozone this produces deadly poisons
right-o Moby acid rain is another way of air pollution
air pollution can be caused by wildfires volcanic eruptions and cow burps
cows contain methane
car engines cause air pollution
Humans and their environment
the 3 ways to help the environment are conserving ,chiming in ,and cleaning up
For the last 200 years humans have greatly impacted the environment
During the industrial revolution human . population increased and caused lots of pollution
Using non renewable resources such as plastic is causing major problems
humans can do things to help the environment because we need to for our survivals.
