This world belongs to everyone and all goodness on it. Both articles are quite saddening that they pointed clearly how much endangerment that various species are facing, especially the marine habitats. Many had said the seas are never as clean as before, after subsequent oil spillage incidents and constant pollutions.
Ocean acidification has affected almost the entire marine population. As explained in an article that it is caused by excessive carbon dioxide (CO2) in the ocean. Unfortunately, such effects are mostly human-generated, by our excessive emission of CO2 on a daily basis. The water temperatures are also rising, making the sea environment less suitable for breeding and growth.
Secondly, global warming is depleting Antarctica rapidly. It causes the sea level to rise at an alarming rate, posing a great danger to most waterfront cities and towns. On top of that, it also reduces the availability for Antarctica’s species to breed and live. With that situation, many of them were under endangerment, or even close to extinction. The same problem also applies to the habitats in Arctic Circle, when glaciers become rivers and tundra become forests, the Arctic animals are losing foothold too.
Lastly, the constant pollutions also make these species become exposed to diseases and unnatural impairments. It totally makes them unsuitable for human consumptions. Perhaps, before they were caught by fishermen’s net, the entire population has shrunken and extinct.
Thus, in order to prevent such tragedies, there is urgency in implementing appropriate measures and regulations. There are short term and long term goals and expectations before we can actually improve these situations. The practical move will be controlled fishing, to allow them to breed and reproduce at a controllable rate. If possible, an artificial sea or a converted lake could be used to breed endangered species. However, the most important way would be reducing the pollutions that are happening every second to the oceans and all its habitats. I agreed fully to Simon Stuart, the Chairman of IUCN’s Species Survival Commission, that “Ordinary people are not powerless to stop these tragic losses.” In fact, it only takes one’s initiative to making the world better.

Fish, animals, trees, plants, these are the examples of living things which could suffer from extinction. We can say that the extinction of these living things are actually caused by mankind.
Since the goal of continuous development have been an issue towards mankind, companies or factories oversea have been clearing forest for more land usage for the operation of their goal. Similarly, these clearing of forests are usually operated using fire due to cheap operation cost.
Huge amount of Carbon Dioxide is produced when such operation occurs. These emitted Carbon Dioxide actually causes global warming and this is where it threatens animals such as the ones living in the arctic area.
We can see that one simple mistake mankind make can actually affect many animals, plants and trees from different places. Their habitat have been ruined and there is no way these animals and plants can reverse the situation without the help of thoughtful mankind. In the world now, clearing of forests is only a part of developing, we must not forget that some of the cleared forests are used as factories and such factories again emit Carbon Dioxide. From a small situation like this, we can see how has mankind caused severe damage to the environment causing several animals to lose their natural habitat and close to extinction. These are some of the factors that caused damage to biodiversity on land.
Fish has been a common food for mankind. Sometimes smaller fishes are food of bigger fishes. In the world now, many people have purchasing power. They can afford to buy fishes for their meal. Fishes are one of the most expensive food compared to chicken, duck or vegetables. So there is a high demand for fishes. Similarly, fishers would catch more fishes as possible to earn money or have it as their main animal protein source in the poorer countries. Ocean fishes have now estimated come to extinction in the year 2050 if mankind do not think of their future. Which means the next generation won't get to enjoy fishes as meal. A high demand in fishes prompt fishers to fish for large amount leaving the poor fishes little time for reproduction purposes. In this way, it could lead to a faster extinction rate.
There's also information that proposals on endangered species were defeated Japan. This shows that there is a slim chance of protecting our future flock of fishes. From the above situations, we can see that mankind is the cost of endangering these living things. Maybe now, we don't care. Maybe then, we regret. But it is all too late to decide when the time comes. Therefore, mankind are urged to take such problems into consideration in order to save ourselves and the poor endangered species for a better future.
