A sustainable resource is a resource that is used up at the same speed that it is renewed. Wood can be a sustainable resource if the trees are harvested at the same rate as new trees mature. Wind is a sustainable resource as the wind is not "used" up. Solar and hydroelectric power can be considered sustainable. Oil, natural gas, minerals taken from the earth do not regenerate and are non-sustainable. Fish stocks can be renewed and can be used in a sustainable fashion but are presently being used at a greater rate than they are being renewed and are considered non-sustainable.
Bacteria eat dead organic matter and release trapped carbon atoms as CO2.
The molten core of planet Earth is the source of heat for geothermal energy.

Dumping and burning
Milk production now causes much more pollution than it used to, mostly because so much of the production is consolidated into really large dairy farms, and disposal of that kind of liquid waste is difficult without poisoning nearby water sources.
: High rains increase the water supply.
Find a way to burn the waste without releasing chemicals
No, the melting of the polar ice caps is the result of global warming.
Use more coal to make electricity(apex)
greenhouse gas levels would decrease
global warning would be decreased

they warm the planet
crops that grow more reliably
A citric acid is added to the solution but the pH of the solution does not change
