Global warming is another thing causing polar bears to die. Polar bears are loosing sea ice habitat because the ice is melting, since polar bears live and survive on Arctic ice, thus
Lipoczi 1 Richard Lipoczi EMLS-112 Marely Cervantes 08. 01. 2011 Myth of the Mammoth’s Extinction Scientists explored the reasons of the extinctions to get to know more about natural forces and factors that could have an effect on species’ vanishing. For the sake of this purpose they analyzed animals that had been disappeared a long time ago because at that time less human impact could just be on their fade-out. They counted in the possible causes the change of the Earth’s temperature, and they noted down the alteration of flora and landscape beside the new animal species’ appearance; in addition, they rated inside the scores the overhunting by humans, and they also kept important point the diseases by the parasites that had been carried the most frequently by the early people and their domestic animals.
3. Climate change has had several impacts on the animals of the arctic tundra. Polar bears, even though they hunt on ice and not on the tundra have seen their food supply decrease due to the melting ice. Since the polar bears can’t find food on ice they look for food in the tundra usually near humans which has led humans to have to shoot polar bears since they became too dangerous near humans. Also, since new species of plants have invaded the arctic some animals can’t adapt to them, like the Caribou which numbers have decreased.
Which is a class c felony and they will be fined of $50,000 to $200,000 plus three years in prison. According to the collage of tropical agriculture and human resources university of Hawaii at Manoa said that in 2003 there was an effort to eradicate the frogs with citric acid but because they bread quickly they are not able to kill
Tropical rainforests are rapidly disappearing in a way that will greatly have an impact on planet earth. Since 1950, half of all tropical rainforests are gone because deforestation, mining and many other things are taking nature away from us. In a few decades, it has been estimated that the rest will be gone if we measures are not taken soon. The WWF (World Life Federation) oversees this ecological threat. They are working to save nature by helping people live in harmony with nature.
What we call pristine today is a poor reflection on what it would be if homo sapiens had never evolved. “America would have over three times as many species of animals weighing over 1000 pounds as Africa does today.” Wilderness that once covered Europe has been reduced to half a million acres of woods straddling the boarder between Poland and Belarus. Environmental destruction by us has become very evident. Although I believe it is very near impossible, Weisman illustrates what the planet might be like today if all humans suddenly disappeared. He uses examples of places that have already been devoided from humans and how nature has taken over.
Animals moving to different locations mean more space for other species. The worst effect of climate change on plants and animals is extinction. There are estimations that, if temperatures continue rising the way they are now, 20-30% of species
Jared Diamond explains in his article “Easter’s End” what happens to societies when they are not sustainable: even though Polynesian colonists inhabited Easter Island around 1,600 years ago they still managed to destroy nearly all of the island’s forests, on which they depended for their livelihood. As a result, they could not maintain the conditions that would sustain their society, and the civilization disappeared. If this could happen 1,600 years ago before technology, nowadays it is likely to happen twice as fast. If we want to avoid a collapse like that of Easter Island, we need to be a more sustainable society. The way we live our lives today, the way our products are manufactured and transported, the energy systems we use, and
Just prepared. North America is home to three species of bears. But because most of us aren’t likely to head out for a day hike in the Arctic, I’ll skip polar bears and focus instead on grizzlies (also known as brown bears) and black bears. • Grizzly Bears Range: Grizzlies have been eliminated from 98 percent of their native range in the American West and the Great Plains, according to the environmental organization Defenders of Wildlife. They’re now found from Alaska (the population
Though this varies in definition, the most drastic forms is perhaps the Pyrolobus Fumarii, a type of thermophile that lives in an environment at a temperature of 105 Degrees Celsius. When this organisms loses its heat, and the environment falls below 90 Degrees Celsius, the thermophile stops growing and multiplying. As the family branch of these many species continues to grow, the many scientists are looking back on the “Archea” to further their understanding of living in the life conditions on earth millions of years ago. Life on earth started with little oxygen and no atmosphere, as well as being increasingly active, as extremophiles share this characteristic of “unlivable conditions” they may be the closest living link to the first form of life. The use of extremophiles is quite small compared to the amount of use we have so far found in many eukaryotes and bacteria.
