just some feelings

On Saturday, we went to the Columbus Zoo ,which is one of the top ten zoos in the United States of America to have the special trip with the animals. And I am just going to write a few words about my zoo trip yesterday. I really enjoyed myself there,and in thinking about it,what we should do that connect to wildlife and climate,and the importance of the zoo for us, and for the environment. We must make something as the alarm to teach people to be aware of the significance for us to live friendly with the environment, that means the earth is not just for the human beings, it is also for the animals, which is also an important part of our lives. As we all know that, a balanced ecosystem is of significance for protecting the earth and the environment. So we should do some necessary events to treat animals and plants mildly to balance the ecosystem.
It is really great to see so many kinds of animals, and especially that I got excited about enjoying the chance to see so closely the polar bears, koala and so many other animals which are not common to see in the zoo. Then I just want to take the polar bears as the example to talk about something on environmental protection.
When I searched the Internet, I got some detailed information about the lovely babies. The polar bear is a bear native largely within the Arctic circle encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. Although it is closely related to the brown bear, it has evolved to occupy a narrow ecological niche, with many body characteristics adapted for cold temperatures, for moving across snow, ice, and open water, and for hunting the seals which make up most of its diet. Although most polar bears are born on land, they spend most of their time at sea and can hunt consistently only from sea ice, so spend much of the year on the frozen sea.
So we can learned global warming as the most significant threat to the polar bear, primarily because the melting of its sea ice habitat reduces its ability to find sufficient food. And the IUCN states, "If climatic trends continue polar bears may become extirpated from most of their range within 100 years." According that, we may can draw a conclusion that the climate has already been changing all the time. And global warming is one of the most typical phenomenon that presents the climate change. The key danger posed by global warming is malnutrition or starvation due to habitat loss. Polar bears hunt seals from a platform of sea ice. Rising temperatures cause the sea ice to melt earlier in the year, driving the bears to shore before they have built sufficient fat reserves to survive the period of scarce food in the late summer and early fall. Reduction in sea-ice cover also forces bears to swim longer distances, which further depletes their energy stores and occasionally leads to drowning. And a warming climate is expected to affect various other aspects of polar bear life. Maybe the final consequence waiting for the lovely bears is only extinction if the environment still like this now.And people will disappear some days later······
Animals really can be a important part of our life, and we should be grateful for all the reminders that the zoo offered us to protect our environment at a time.

thank you so much for your generosity when i needed to call back home. you really helped me.

sorry for last night's call out. when they told me Jean was out alone to the art school, i was so worried, i forgot you had told me you were feeling uncomfortable in your "situation". forgive me.

Lucia, I think every student knows you just want the best for them and are trying to make sure everyone is safe!

And Cindy, I really like how you used details and facts about the polar bears in your post. I missed some of that and was happy to read it. Great job!
