SUSTAINABILITY OF NATURAL RESOURCES :earth_americas:
Fossil fuels
Recycling
Humans and Their Environment
The are 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 advances but there are now 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 environment
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 2 types which are renewable and nonrenewable
Climate change
The earth gets warmer naturally but this is much faster
Global warming is caused by gases that trap heat
Global warming is the average temperature of the earth
Humans burning fossil fuels is putting more greenhouse gases in the atmosphere
Trees remove CO2 so we need to plant 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
In 10 years there will be more than 8 billion people on Earth
About 200 years ago the human population increased by a lot
Recycling can reduce how much recourses are being used
Earth can only hold a certain amount of people
Soil
Air, rock, water a humus make up soil
Weathering and erosion
Plants need rock and humus to grow
Erosion moves the sediment to other places
Soil has different layers and the top soil has the most humus
Soil is a mix of rocks, water and dead stuff
Weathering breaks rocks into small pieces called sediments
Plants cannot grow in bed rock, so we must protect our top soil
Air pollution
Can come from different places such as cars
Burning fossil fuels reales poisonous gases such as CO2
Can cause cancer and global warming
Can even make people that are healthy sick and people that are already sick even more sick
Ozone layer, when its up high, protects us from the sun but becomes poisonous if its lower
Can mix with clouds to cause acid rain
Cows produce lots of methane, which is a greenhouse gas
Conserving our resources will cause less air pollution
Greenhouse Effect
Is the warming of Earth
Greenhouse gases such as CO2, traps heat on Earth
Without the greenhouse gases, Earth will be too 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
