Its past due! in 2015 in alaska, an enormous number of walrus females and their calves gathered on a single beach. in the past, the walruses would use sea ice as a place to rest and nurse their calves, but due to human activity and global warming, large amounts of the ice have melted. explain what consequences could happen to the walruses and their ecosystem in this situation over time.

Hi!

Question - In 2015 in Alaska, an enormous number of walrus females and their calves gathered on a single beach. In the past, the walruses would use sea ice as a place to rest and nurse their calves, but due to human activity and global warming, large amounts of the ice have melted. Explain what consequences could happen to the walruses and their ecosystem in this situation over time.

Answer - Since there is so much global warming problems it rises the temperature of earth. Female walruses nurse their calves on ice blocks but since most, or not all have been melted they cant nurse in the future because there not used to a different environment. Eventually over time their species will die out and become extinct.

a fossil fuel is a fuel formed by natural processes, such as anaerobic decomposition of buried dead organisms, containing energy originating in ancient photosynthesis.[1] the age of the organisms and their resulting fossil fuels is typically millions of years, and sometimes exceeds 650 million years.[2] fossil fuels contain high percentages of carbon and include petroleum, coal, and natural gas.[3] other commonly used derivatives include kerosene and propane. fossil fuels range from volatile materials with low carbon to hydrogen ratios like methane, to liquids like petroleum, to nonvolatile materials composed of almost pure carbon, like anthracite coal. methane can be found in hydrocarbon fields either alone, associated with oil, or in the form of methane clathrates.

the theory that fossil fuels formed from the fossilized remains of dead plants by exposure to heat and pressure in the earth's crust over millions of years was first introduced by andreas libavius "in his 1597 alchemia [alchymia]" and later by mikhail lomonosov "as early as 1757 and certainly by 1763".[4] the first use of the term "fossil fuel" was by the german chemist caspar neumann, in english translation in 1759.[5]

in 2017 the world's primary energy sources consisted of petroleum (34%), coal (28%), natural gas (23%), amounting to an 85% share for fossil fuels in primary energy consumption in the world.[6] non-fossil sources in 2006 included nuclear (8.5%), hydroelectric (6.3%), and others (geothermal, solar, tidal, wind, wood, waste) amounting to 0.9%.[7] world energy consumption was growing at about 2.3% per year. in 2015 about 18% of worldwide consumption was from renewable sources.[8]

i wish i could with all of them i can barley see the first one so here's the answer to the first one b
