sustainability of natural resources
soil
soil is a mix of rocks and stuff that is dead
weathering and erosion break rocs into smaller pieces
soil contains humus (dead) and rocks, which helps plants to grow
soil has different layers and the topsoil is the most nutritious
plants can not grow in the bed rock so we must take care of the topsoil
air pollution
air pollution can have different sources such as cars
burning fossil fuels releases poisonous gas such as CO2
air pollution can cause cancer and global warming
ozone protects when its high in the atmosphere, but poisonous when its low and near us
air pollution mixes clouds to make acid rain
cows release methane, which is greenhouse gas
if we conserve our resources, then it will cause less air pollution
climate change aka global warming
we can help stop global warming by using less fossil fuels, conserving energy, and usuing renewable resources
cutting down trees helps the earth by cooling down
green house gases, such as carbon dioxide traps heat on the earth
global warming is about the increasing temperature of the earth
earth's climate change naturally, but humans are causing it to happen faster
burning fossil fuels adds more carbon dioxide to our atmosphere
global warming leads to lots of problems, such as bad weather and diseases
natural resources
we can conserve our resources by changing our habits
there are two types, renewable and nonrenewable
anything in nature that we value
there are many natural resources, such as air, water, soil, etc
renewable does not mean that it will never run out
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 recourses faster
in about 10 years there will be at least 8 billion people on earth
humans can reduce their use to help with conservation
recycling is a good way to conserve our resources
green house effect
there are gases that make the Earth warmer
some of the sun's heat goes back into space
green house gases such as Co2 absorb and trap the heat on earth
earth warms up and cools down naturally but to much gasses cause global warming
green house gases such asCos and methan, by humans is the main cause of global warming
humans and the environment
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
