Sustainability of natural resources
Fossil fuels
conserving energy
recycliong
Natural Recources
Anything in nature that people value
Air, water, fossil fuels, and animals are natural resources
Plastics are not natural resources
There are 2 types which are renewable and nonrenewable
Reducing, reusing, and recycling helps to conserve our resources
Green house affect
Climate change
Global warming is the average temp. of Earth
Earth gets warmer natural but it is happing a lot faster
Global warming is caused by gases that trap heat
Humans burning fossil fuels is putting more greenhouse gases in the atmosphere
Trees remove carbon dioxide, so we need to add more trees
Global warming is causing bad weather and diseases, but we can still fix the problem
Humans should use less fossil fuels and more renewable resources
population growth
Earth can only hold a certain amount of people
About 2 hundred the human population increased by a lot
More people are on Earth is using up our resources more quickly
In 10 years there will be more than 8 billion people on Earth
Recycling can reduce how much resources are being used
soil
Soil is made of rocks, water, air and humus
Air, water, ice, co2 and o2 break down the crust to give the rock part of the soil
Erosion moves the sediments to other places
More humus helps the plants grow
Soil has different layers and top soil has the most humus
Plants cannot grow in bedrock so we must take care of the top soil
Air pollution
Air pollution can come from different places
Burning fossil fuels releases poisons gasses such as CO2
Air pollution can cause cancer and global warming
Ozone is up high and protects us from the sun by is poisonous when it is close to us
Air pollution can mix with clouds to cause acid rain
Cows produce lots of methane which is a methane gas
Conserving our recourses will cause less pollution
Greenhouse Effect
Greenhouse Effect is the warming of earth
Greenhouse gases such as CO2, trap heat on the Earth
Without the greenhouse gases, Earth would be too cold to live on
Too much greenhouse gases can cause global warming
Humans can reduce global warming by burning less fossil fuels and rising less cows (methane)
Humans and their environment
The 3 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 causes lots of population and will eventually run out
For our survival, we need to do things to help the environment
