Sustainability of Natural Resources
Humans and their envoirnment
The 3 ways 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 more people which lead to more pollution
Using nonrenewable resources, such as plastics, causes pollution and will run out
For our survival, humans can do things to take care of the environment
Greenhouse Effect
Climate Change (aka Global Warming)
Global Warming is about the increasing temperature of the earth
Earth climate changes naturally but, humans are making it warm up faster
Greenhouse gases such as carbon dioxide trap heat on the earth
Burning fossil fuels adds more carbon dioxide to the earth atmosphere
Cutting down trees stops the earth from cool down
Global warming can cause bad weather and diseases, but humans can still fix the problem
Natural Resources
Anything in nature that people value
There are many natural resources such as air, water, soil etc.
There are two types of resources which renewable and non-renewable
Renewable does not mean it will never run out
We can conserve our resources by changing our habits
recycling
Air Pollution
Air pollution can have different sources, such as cars.
Burning fossil fuels releases poisonous gases such, such as CO2
Air pollution can cause cancer and global warming
Ozone protects us when its high in the atmosphere, but its poisonous when its low and near us.
Air pollution mixes with the clouds to create acid rain
Cows release methane, which is a greenhouse gas
If we conserve our resources, then it will cause less air pollution
Conserving Energy
Population Growth
Soil
Soil contains humus and rocks which helps plants to grow
soil has different layers and the topsoil is the most nutritious
Plants cannot grow in bedrock, so we must take care of the topsoil
Soil is a mix of rocks and dead stuff
Weathering and erosion breaks rocks into small pieces
Greenhouse effect
There are gases that make the earth warmer
Most of the suns heat goes back into space
Greenhouse gases such as CO2 absorb and trap the heat on earth
Earth warms up and cools down naturally, but too much gases causes global warming
Greenhouse gases, such as CO2 and methane, by humans is the main cause of global warming
