How are animals affected by oil spills?
Oil destroys the insulating ability of fur-bearing mammals, such as sea otters, and the water repellency of a bird’s feathers, thus exposing these creatures to the harsh elements. Without the ability to repel water and insulate from the cold water, birds and mammals will die from hypothermia.
What animals were affected by the oil spill?

What happens when oil is removed from Earth?
When oil and gas is extracted, the voids fill with water, which is a less effective insulator. This means more heat from the Earth’s interior can be conducted to the surface, causing the land and the ocean to warm. We looked at warming trends in oil and gas producing regions across the world.
How does oil cause pollution?
Air pollutants result from burning oil and natural gas. In addition, pollutants can leak out of storage tanks during oil and gas production and distribution. For example, when oil is burned for electricity, sulfur dioxide, mercury compounds, and nitrogen oxides are produced.

Can you burn animal fat?
Use Animal Fat as a Wet Weather Fire Starter It’s one of the most commonly used food energy units in the world. To describe it very simply, it’s something that can “burn” to produce heat. It’s also true when we light animal fat on fire.
Which is better animal fat or vegetable oil?
Animal fats are mostly saturated fat, which means they stand up better to high heat and last longer than vegetable fats. Reduced oxidation in animal fats means they are less susceptible to the toxins and carcinogens generated by using vegetable oil alone.
