There are three main gases involved in agriculture: nitrous oxide, carbon dioxide, and methane.

Nitrous oxide
Nitrogen can be absorbed by lightning, which is pretty cool, and then it falls in rain (atmosphere). It's also used in a lot of fertilisers. Either way, it's absorbed by the plants (biosphere). Since it falls in rain, the runoff can lead to rivers or oceans (hydrosphere).

Carbon dioxide
Carbon dioxide is absorbed by plants and is stored as carbon (biosphere). It can also be released through respiration from both humans, other animals, and plants, and through burning fossil fuels (atmosphere). A lot of it is absorbed by the soil from plant decay (lithosphere).

Methane
This is usually produced in one of the stomachs of cows or sheep during digestion (biosphere? maybe??), and is released through burps (atmosphere). Smaller amounts are released from the fermentation of animal dung and urine.

How can we fix it?
Just some short ideas.
Nitrogen: farm the land in a formation that allows for less run-off
Carbon: Avoid burning crop residues
Methane: Improve quality of the feed for livestock so that less methane is produced to digest it

Burning fossil fuels releases massive amounts of carbon dioxide and other gasses into our atmosphere, which is warming our earth. This is known as climate change.

Climate change isn't our only problem though, burning fossil fuels is damaging for a multitude of earths delicate systems.

The burning of fossil fuels is a heat-intensive process and needs lots of freshwater to cool it down. This freshwater is drawn from local rivers and lakes changing the entire ecosystem, sometimes drying them up completely.

Acid rain is a massive issue for us, as it is an environmental hazard, but also for animals and plants. Fossil fuels release chemicals that bind with water vapour and can contaminate water sources, harming the fish population and making it undrinkable.

We need to eliminate the burning of fossil fuels completely, and substitute it for greener methods, such as using renewable energy.

Ways to improve:
- Using renewable energy such as solar, wind or water
- Stop using fossil fuels for power generation
- Use greener ways to produce energy such as nuclear powerplants

Deforestation increases carbon emissions, changes the water cycle and causes soil erosion. Not only is there an increase in carbon emissions, but there is also an increase in how long the carbon is in the atmosphere for. When this time period is expanded a layer in the atmosphere is formed which then traps the solar radiation, ending in global warming. Deforestation also decrease the amount of precipitation which causes changes to the volume of water in things like rivers, lakes, swaps etc. It can also change the flow of the river. Deforestation also causes soil erosion. Soil erosion removes the top layer of the soil which is the most fertile, making it hard for plants to grow and find nutrients. Soil erosion also has been known to cause increased pollution and sediments in rivers, streams and other body's of water. Clogging the waterways and causing loss of life in these water.
When soil is stripped from its nutrients, the water cycle has been messed up and there are more carbon emissions than ever. The area becomes toxic, plants take longer to grow or cant grow at all. Animals that werent killed in the proccess of logging they now have no home and no food. these animals slowly start dying. Not only do we end up loosing unqique species of animals we also loose, plants and fungis]]> 2022-08-09 02:46:43 UTC https://padlet.com/jimthegeologist/6z9mdmo8jvgmsur7/wish/2257112575 Car Emissions (Pyrate) https://padlet.com/jimthegeologist/6z9mdmo8jvgmsur7/wish/2257113360 What causes the production of gas?

Our cars emit approximately 24 pounds of carbon dioxide per gallon of gas, which contributes significantly to global warming.

What can we do to put a stop to this?

Using electric vehicles can effectively reduce emissions. Driving an electric vehicle requires more effort but produces no emissions as a major bonus.

Another option is to purchase or manufacture more fuel-efficient automobiles, by doing so, we can still travel a great number of distances while lowering emissions
