SUSTAINABILITY OF NATURAL RESOURCES
Recycling
Fossil fuels
Climate change
Conserving energy
Natural resources
Solar energy
Anything in nature that people value
Air, Water, Fossil fuels, Plants, and Animals are natural resources
Plastics are note natural resources
There are 2 types which are renewable and nonrenewable
Reducing, Reusing, and recycling helps to conserve our resources
Global warming is the average temperature of the earth
Earth gets warmer naturally, but this is happening alot faster
Global warming is caused by gasses 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

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 our earth is using up our resources more quickly.
In 10 years, there will be more than 8 billion people on earth
Recycling can reduce the amount of resources we use
Soil
Soil is a mix of rocks, water, and dead stuff
weathering breaks rocks into small pieces
erosion moves the sediments to other places
more humus helps plants grow
soil has different layers and the top soil has the most humus

air pollution
Air pollution can come from different places
burning fossil fuels releases poisonous gasses
Air pollution causes cancer and global warming
Ozone when its up high protects us from the sun, but when it is closer to us it becomes poisonous
Air pollution can mix with clouds to acid rain
Cows produce lots of methane which is a greenhouse gas
Conserving our resources will cause less air pollution
Greenhouse effect
Greenhouse effect is the warming of earth
Greenhouse gasses such as Co2 ( carbon dioxide)trap heat on earth
Without the Greenhouse gases, earth would be to cold to live on.
Too many 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
humans and their environment
the 3 things you cn do to help the environment are conserving, cleaning up, and chiming in.
during the industrial revolution, there was more and more population
in the last 200 years humans have greatly impacted the environment
using non renewable resources causes lots of pollution and will eventually run out
