SUSTAINABLITY OR NATURAL RESORCES
Natural Resources
Anything in nature that people value
Air, water, fossil fuels, plants and animals are natural resorces
Plastics are not natural resorces
There are two types, which are renewable and nonrenewable
Reducing, reusing and recycling helps to conserve our resources
CLIMATE CHANGE
global warming is the average temp of earth
Earth gets warmer naturally but this is happening a lot quicker
global warming is cause by gasses that trap heat
Burning fossil fuels is putting more greenhouse gases in the atmosphere
trees remove carbon diozide, so we need to plant more trees
global warming is causing bad weather and diseases
POPULATION GROWTH
Earth can only hold a certain amount of people
about 200 years ago the human population increased by a lot
More people on earth is using up our resources
In 10 years there will be more than 8 billion people on earth
recycling can reduce how many resources are being used up
Soil
Soil is a mix of rock, water, air and humus
erosion moves the sediments to oter places
weathering breaks rocks into small pieces
more humus helps the plants to grow
soil has different layers and top soil has the most humus
plants can not grow in bed rock so we must take care of the topsoil
Air Pollution
air pollution can come from different places such as cars
burning fossil fuels releases poisons gasses such as c02
air pollution can cause cancer and global warming
ozone when its up high protects us from the sun, but becomes poisonous when its near us
air pollution can mix with clouds to make acid rain
cows produce lots of methane, which is a green house gas
conserving our resources will cause less pollution
Greenhouse Gasses
Greenhouse effects is the warming of earth
Greenhouse gasses, such as CO2, trap heat on the earth
Without the greenhouse gasses, Earth would be too cold for us to live on
too many greenhouse gasses can cause global warming
Humans are causing global warming
Humans can reduce global warming by burning less fossil fuels and raising less cow(methane)
Humans and their Environment
The three things you can do to help the environment is conserving, cleaning up and chiming in.
In the last 200 years, humans have greatly impacted the environment.
During the industrial revolution there was more people and more population
Using nonrenewable resources cause lots of pollutionand will eventually run out.
for our survival, we need to do things to help the environment
