Sacrification corrosion, also known as galvanic corrosion, is an electrochemical process in which one metal corrodes preferentially when in electrical contact with a different type of metal in the presence of an electrolyte. This occurs due to the difference in the electrode potentials of the two metals, leading to accelerated corrosion of the more reactive metal. To prevent sacrification corrosion, measures like using corrosion-resistant coatings or isolating the metals from direct contact can be taken.
not sure but im guessing they had to pray or make a sacrification to the messenger god while they were traveling to keep them safe. another answer here from someone else i don't know this guy is right but I'll find out soon.
The Taiga is being destroyed everyday by both humans and nature. Nature causes forest fires with lighting, diseased by parasites or herbicides, and spruce trees that grow on top thick moss are frequently blown over by strong winds. Large-scale clear cutting, plantation forestry, introduction of exotic tree species, soil sacrification, ditching, and use of pesticides or herbicides have led to habitat loss. Large-scale industrial forestry, or logging, is the greatest important threat effecting the boreal forest. The wood is used in the "pulp factory" for pulp and paper. Other threats to the Taiga are oil and gas exploration, road building, mining, human triggered forest fire, and climate change. Animals of the Taiga are being hunted and trapped for their fur which decreases their population greatly. Hydroelectric power has ruined the water system. Many fish have mercury poisoning. The Taiga is being destroyed equal to that of the rainforest.Destruction of the Taiga is harmful to humans as well as animals and we need to save it! Forestry destroys the people of the Taiga's native culture; all memories are chopped down to make tissue and paper. Living in an unhealthy forest makes an unhealthy community. To save the Taiga people must decrease the use of paper and wood products. Inform your local schools, government, and wood product industries of the dangers of the Taiga. Form a supporting group or join one to help protest the land rights of the Taiga. Help save the Taiga!To save the animals we can protest for their rights and have them protected. Use e-mail and send a message to friends and family to stand up and tell the wood product industries what they're destroying and that it needs to stop! Raise money to reserve to reserve land on the Taiga. Don't waste any paper or tissue or any other wood related products. Use wood products less and less and you may help more than you think. Think before you throw away, recycle!
