Sustainability of Natural Resources
Humans and their environment
The 3 ways to help our environment is conserving cleaning up and chiming in
In the last 200 years, humans have greatly impacted the enviroment
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 our enviroment
Conserving energy
Air pollution
Air pollution can have different sources, such as cars
Burning fossil fuels releases poisonous gases such as CO2.
Air pollution can cause cancer and global warming
Ozone protects us when it's high in the atmosphere, but poisonous when its low and near us.
Air pollution mixes clouds to create acid rain
Cows release methane, which is a greenhouse gas
If we conserve our resources, then it will lead to less air pollution
Recycling
Population Growth
Natural Resources
anything in nature people use
There are many natural resources such as air, water, soil, etc.
There are 2 types, which are renewable resources and nonrenewable
Renewable does not mean it will never run out
We can conserve our resources by changing our habits
Climate Change (aka Global Warming)
Global warming is about the increasing temperature of the Earth
Greenhouse gases such as carbon dioxide, trap heat on the Earth
Earth's climate changes naturally but humans are making it warm up faster
Burning fossil fuels adds more carbon dioxide to the atmosphere
Cutting down trees, stops the Earth from cooling down
Global Warming can cause bad weather and diseases, but humans can still fix the problem
Greenhouse Effect
There are gases that make the Earth warmer
Greenhouse gases, such as CO2, absorb and trap the heat on Earth
Some of the sun's heat goes back into space
Earth warms and cools down naturally, but to much gases causes global warming
Greenhouse gases, such as CO2 and methane, by humans is the main cause of global warming
Soil
Soil is a mix of rocks and dead stuff.
Weathering and erosion break rocks into small pieces
Soil contains humus (dead stuff) and rocks which help plants to grow
Soil has different layers and the topsoil is the most nutritious
Plants cannot grow in the bedrock, so we must take care of the topsoil
