Sustainability of natural resources
conserving energy
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, which are renewable and non renewable
reducing, reusing, and recycling helps to conserve our recourses
energy sources
population growth
earth can only hold a certain amount of people
about two hundred years ago the human population increased by a lot
more people on earth us using up our resources more quickly
in ten years there will be more then 8 billion people on earth
recycling can reduce how much resources are being used
Greenhouse Effect
Greenhouse effect is the warming of earth
Without the greenhouse gases, Earth would be too cold to live on
Greenhouse gases, such as CO2, trap heat on the earth :
Too many greenhouse gases can cause global warming
soil
Soil has different layers and the topsoil has the most humus
Erosion moves the sediments to other places
Soil has different layers and the topsoil has the most humus
Weathering breaks rocks into small pieces called sediments
Plants need rocks and humus to grow
Plants cannot grow in bedrock, so we must protect our topsoil
climate change
global warming is cuased by gases that trap heat
earth gets warmer naturally but this is happening much faster
global warming is the average tempreture of earth
humans burning fossil fuels is putting more greenhouse gases in the air
tress remove carbon dioxide so we need more trees
global warming is causing bad weather and diseases but we can still fixed the problem
humans should use less than fossil fuels and more renewable resources
Air pollution
Air pollution can come from different places, such as cars
air pollution can cause cancer and global warming
Burning fossil fuels releases poisonous gases, such as CO2
Can even make people that are healthy sick and people that are already sick even more
Ozone when its up high protects from the sun bu becomes poisonous if its lower
Air pollution can mix with clouds to cuase acid rain
cows produce lots of methane which is a greenhouse gas
Conserving our resources will cause less air pollution
