Danger of Extinction

According to the article “The brown pelican’s return to coastal Louisiana” the author states that brown pelicans have a history in Louisiana, but they disappeared from there. Brown pelicans arrived in Louisiana because Iberville, first coasting of the Gulf of Mexico, took the pelicans and carried on to the New World with 24 feminine birds in hope that they would provide an incentive for permanent settlements. Then in 1966 the pelican received the honor to being officially adopted as the state bird. However the author explains that the pelican bird started to decrease it’s population in the state of Louisiana until they totally disappeared. The scientist began to study why the pelican had disappeared; they could not have proof to know at that moment why the birds migrated. They believed that the reason had been two tropical storms in 1956 and 1957. However, years later, in California, the pelicans started to disappear too but the research found that thousands of pounds of the pesticide DDT had been used in the state. Fishes that are part of the food of the pelicans had absorbed the DDT. As a result of this in 1968 the Louisiana state started a program to restocking brown pelicans. They transported the pelicans from Florida. The program started to be successful and the birds started to increase and sustain their population.

So many of the environmental problems are caused by humans but human cannot migrate across, the Earth like pelicans did when they did not find food. However some of the humans can create a lot of programs to help to maintain the Earth. Also humans are intelligent to use the technology to help the Earth and try not to cause more damage.

Humans are always creating pollution without thinking of the environment. The problem is that when they started to think about the environment, it could be too late. Every day too many species disappear from the Earth because of the damage of humans and one of these species could be humans too. Humans do not have the possibility to migrate to another planet, like the movie WALL-E. Neither do we have the possibility to move to another country like brown pelicans, because we are too many people for just one country. Humans have to be more conscious to think about the future. Humans have to respect the environment to subsist in the Earth. We have proof of the damage that we are causing and the migration of the pelicans can be one example of this. Humans do not have possibilities like pelicans.

However humans can start to create some programs in order to protect the environment. The program that Louisiana State started protected one of the species of the Earth. Humans have to take the environmental problems seriously. They have to start to take seriously the methods of reuse, recycle and reduce. It is incredible that people, knowing the environmental problems that the Earth has, are not worried about doing something. Every day you can see in the place to recycle a lot of things that are not to recycle. Even if people have to places to put the garbage, they mix everything recyclable and not. However it is important to create educational programs to explain to people how they can take care of the environment.

Humans have to think about how they can create technology to help to clean the environment without causing more damage. Some person is creating a machine those functions in order to clean the air pollution. Mexico City is one of the cities where the machine had been tested. Humans have to figure out the problem of why green technology is more expensive than regular technology. Whirlpool, for example, has a line of washing machines that are green and not cause damage to the environment, but this line is the most expensive, and no one will buy it. Humans have technology and they must use it for the best.

Humans can continue causing damage to the environment, but they could disappear if they are too late. If the human race wants to live in the Earth forever, they have to think of the planet. They have to create programs that help to take care of the environment, and they have to use the technology in the same way. The Earth could not be forever.

Consequences of Climate Change by Vanessa Bereciartu

In Hirsch’s (2005) article titled “Animals ‘hit by global warming’” he explains how changes in the temperature of the world can affect the migration of the animals. This information was discussed in the report of the EU nature conservation chiefs in Scotland. Scientists observed that species associated with the south had appeared in the north such as ringed plover birds that are now spending the winter in Britain. Although others animals have migrated to different routes, for some animals that is not possible. Polar bears and seals, whose habitats are changed, are going to disappear. Another consequence that the author explains of the temperature changes is that the plankton has changed, and that contributes to the decline of the breeding success of Scottish seabirds. Then the author mentions some other consequences of the climate change identified in the report. Finally, the author explains that nature can adapt to the changes but the problem is that these changes are too quick. The species does not have enough time to adapt to it. The conservational official in Scotland urged the population to use biological corridors to help animals to adapt to global changes.

Every country have to find a solution for global warming together and there are tree ways to deal with this problem. First developed countries must help undeveloped countries. Second each government has to educate its population. Third countries have to create an intergovernmental organization for take care the environment.

Developed countries are more worried about global warming and they have to help undeveloped countries with this problem. First, because they have enough money to begin programs that help poor countries to change some process of life that make a lot of pollution. For example, in Venezuela they always have oil spills caused by the lack of knowledge of the people. Oil spills can cause contamination in the water around South America. Second, developed countries are more organized, and they can create a commission that helps poor countries to reduce the pollution. Poor countries are always focusing on how they can subsist and they do not have enough time to think about global warming.

Governments have to educate their population because he principal problem of the global warming is not the governments of the countries but the population. People have to be educated in all countries developed or not. People can cause big damage for the nature. For example people in United States consume a lot of energy. They always leave the light and the air conditioner on and that is one of the causes of global warming. Every country has to teach its population, because global warming affects the whole world, including both humans and animals.

A quick solution for this problem could be creating an intergovernmental organization that observes countries about the environmental damage. This organization must be run like the United Nations. Specifically it has to run like the United Nations Security Council. The organization most have a president elected by the votes of every country. They could give a fine to countries that cause damage to the environment. That can help to reduce the pollution and to teach the population. This could be a way to push the countries developed or not to start thinking about global warming and how that can affect the world.

Climate change is a big problem that affects our ecosystem. Humans, animals and plants could disappear from the planet. People have to start thinking about global warming. The beginning must be that developed countries try to help poor countries. Then people have to be educated about the care of the planet. Finally we should encourage the creation of the intergovernmental organization that can help to push the countries to think about the planet. Global warming can make us die.
