Sustainability of Natural Resources
Climate Change AKA Global Warming
Earths climate changes naturally, but humans are making it warm up faster.
Global Warming is the increasing temperature of the Earth.
Greenhouse gases, such as Carbon Dioxide trap heat in the Earth.
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 fix the problem.
Natural Resources
Anything in nature that people value.
there are many natural resources such as air, water, soil, etc.
There are 2 types, Renewable and Nonrenewable.
Renewable does not mean that it will never run out.
We can conserve our resources by changing our habits.
Soil
Soil contains humus (dead) and rocks, which helps plants to grow.
Soil has different layers and the topsoil is the most nutritious.
Weathering break rocks into smaller pieces. Erosion moves them around.
Plants cannot grow in the bedrock, so we must take care of the topsoil.
Soil is a mix of rocks and dead stuff.
Air Pollution
Air pollution can cause cancer, and global warming.
Ozone protects us when its high in the atmosphere, but poisonous when its low and near us.
Burning fossil fuels releases poisonous gases, such as CO2.
Air pollution mixes with the clouds to create acid rain.
Air pollution can have different sources such as cars.
Cows release methane, which is a greenhouse gas.
If we conserve our resources, then it will cause less air pollution.
Greenhouse Effect
There are gases that make the Earth warmer.
Some 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 of the gases causes global warming.
Greenhouse gases, such as CO2 and methane, by humans is the main cause of global warming.
Humans and their 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.
In the last 200 years, humans have greatly impacted the environment.
For our survival, humans can do things to take care of the environment.
The 3 ways to help the environment is conserving, cleaning up, and chiming in.
