Answer #1

The major groups of mammals are : Monotremes, Marsupials, and placental mammals. Examples of monotreme are Platypus, Steropodon, and Echidnas. Examples of marsupials are : Wombats, Phalangeriforme and Opossum. Examples of placental mammals are all type of carnivores, even toed ungulates, and primates. All the three groups are related by the characteristics : their young ones are nourished by milk after birth, their body is covered by fur or hair and sweat glands in the skin, half of their lower jaw is made by single bone called dentary. We should care about mammals eventhough they are the least diversed groups since they play important role in every ecosystem. They are important members in food chain and food web.

Let's take just one issue—should humans assist wildlife threatened by climate change to move to new habitat? Some species, such as mountain-dwelling pikas, are already moving to higher altitudes. But eventually they will run out of mountain. Should we spend scarce resources to move the animals to still-cold locations? What about the animals they might be displacing, the ecosystems their presence would change? Should a threatened species be bred in captivity in the hope that someday suitable habitat will be...
