Sustainability of natural resources
Solar energy
Energy sources
Global warming
Global warming is the average temprature of EARTH
Earth gets warmer naturally, but this is happening 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 plant more trees
Humans and their environment
Conserving and chiming in and cleaning up helps the enviroment.
In the last 200 years, humans have greatly impacted the enviroment
During the industrial revolution, there was more people and more population
Using nonrenewable resources cause lots of pollution and will eventually run out
For our survival, we need to do things to help the enviroment
Natural resources
ANYTHING IN NATURE THAT PEOPLE VALUE
Air water fossil fuels plants and animals are natural resources
Plastics are not natural resources
There are two types are renewable and not
Reducing reusing and recycling helps conserves resources
Earth can only hold a certain amount of people
About 200 years, the human population increased by a lot
More people are on earth is using up our resources faster
In 10 years, there will be more than 8 billion people on Earth
Recycling can reduce how much resources are being used.
Ozone when its up high protects from the sun, but becomes poisonous when its near us
Air pollution can mix with clouds to cause acid rain
Cows produce a lot of methane, which is a greenhouse gas
Conserving our resources will cause less air pollution

Soil
Weathering breaks rocks into small pieces( sediments)
Soil is a mix of rocks water an dead stuff
Erosion movs the sediments to other places
More humus helps the plants to grow
Soil has different layers and the top soil has the most humus
Plants cannot grow in bedrock, so we must take care of the topsoil
Air pollution
Air pollution can come from different places such as cars
Burning fossil fuels releases poisonous gasses, such as CO2
Air pollution can cause cancer and global warming
Greenhouse effect
Greenhouse effect is the warming of Earth
Greenhouse gases, such as CO2, trap heat on Earth
Without the greenhouse gases, Earth would be too cold to live on
Too much greenhouse gases can cause global warming
Humans are causing global warming
Humans can reduce global warming by burning less fossil fuels and raising less cows (methane)
