Sustainability of natural resources :recycle:
Humans and their environment
The three ays to help the environment is conserving, cleaning up, snd chiming in ( talk about it )
For the last 200 years, humans have greatly impacted the environment.
Using non renewable resources, causes pollution and will eventually run out.
During the industrial revolution, there was more people that caused more pollution.
Humans need to take action to improve our environment for our survival
Natural resources
We use energy resources to power to power our cities
Anything in nature that people value
Plastic is not a natural resource, unlike air, water, plants, and animals.
The 2 types of resources are renewable and nonrenewable
Oil Fossil fuels are nonrenewable, unlike solar energy
Reducing, reusing, and recycling can help us conserve our resources
Greenhouse effect
Greenhouse affect is the warming of the earth
Greenhouse gases such as Co2, warms the earth
Too much Greenhouse gases makes the earth too hot (global warming)
Humans are causing more Greenhouse gases
Burning fossil fuels and cows producing methane can be reduced by humans
Climate change ( aka global warming )
Climate change happens naturally but humans are making it happen faster
Global warming is about the temperature of the earth
Global warming is caused by greenhouse gasses, which trap the heat
Humans burning fossil fuels is producing more carbon dioxide
Trees remove carbon dioxide, so we need more trees
Global warming is causing bad weather and diseases but we can still fix the problem
Air pollution
Conserving our resources will cause less air pollution
Air pollution can mix with clouds to acid rain
Air pollution can cause cancer and global warming
Air pollution can come from diffirent places, such as cars.
Burning fossil fuels releases poisonous gases, such as CO2
Ozone when it's up high protects from the sun, but becomes poisonous when it's near us
Cows produce lots of methane, which is a greenhouse gas
Population growth
Earth can support a certain amount of people
About 200 years ago, the human population increased a lot
More humans on Earth is causing more pollution and using our resources faster
In about 10 years there will be more than 8 billion people on Earth
Humans can reduce their use of resources with conservation
Recycling is a good way to conserve our resources
Soil
Soil is a mix of rocks, water, and dead stuff (humas)
Weathering breaks rocks into small pieces called sediments
An erosion moves the sediments to other places
Plants need rocks and humas to grow
Soil has different layers and the topsoil has the most humas
Plants cannot grow in bedrock, so we must protect our topsoil
