all about environmeltal science

there are so many things we dont know thats why we dont do it. and there are many things we know thats why we do it. and there are much more things we know and we dont want to do it. from this class i came to know that we( all human beings and the activities) are the creator of the environmental hazard which is causing problems to us and the animals and the mother earth.

i thing  global warming is an important issue in this century. it is causing problem to many people and wildlife and the biodiversity. we know the causes and we know the solution too. so we all human beings should be togather to work on this problem so that we can make a change and save life of the eath and animals and we people.

alternative energy info

 

in Indiana states the alternative source of energy are wind farm, and the solar panel, which ware helping the people of the Indiana to pay less bills for their electricity. if you’re thinking all this alternative energy seems uncharacteristically progressive for a place like Indiana, you need to get with the times. Wind power has become a big business, and the wind doesn’t blow only in blue states.

Wind energy is one of the most cost-effective renewable energy resources, which is vastly and widely being adopted, especially on a mass scale to be a power generation source. By the mid of 2009, no less than 80 countries were using wind energy on a commercial level.

Unlike conventional fossil fuel power plants, windmills don’t emit any greenhouse gasses and even if they are removed they don’t leave any sort of pollution behind.

Off shore wind farms and those set up at higher altitudes which produce more energy can return the investment in as little as three months, which is why they are becoming more and more popular, especially at homes.

and i thing why there is no wind farms in chicago? this is a windy city so i thing government should take advantage of this natural gift of this city . but while i was researching this issue i found out that windfarms is coming in chicago too pretty soon(zack christmas, NBC chicago).

 

 

population and the world

from my environmental science i got a chance to know that we r using the resource and our earth at the rate of 1.3. it does mean that we are using 1 and the half earth. over population is not causing only a problem to our resources but aslo to many factor. such as:

1. over population is leading to environmental problems

2. expotential population growth and develpoment leads to faster deplition of resources

3. population grows expotentially

4. pollution

now the issue is how to control the existing population. there are many and many methods of controlling the population. educating people, awareness programme, contraceptives etcs

in my openion i think there are adeduate methods of contraceptives. people should know about the contraceptives and start using them if they dont want babies. in my openion people should think twice for having babies if the economic status of the individuals is weaker.

i think abortion and contraceptives are two different things. one contrls not to have conception and another is if something happens in life and baby is cusing problem or mother dont want to have that  child for some reason she can abort the child.

teenages should have free access of certain contraceptive like condoms and birth contrlling pill. it help to control the population as well as to continue teenagers life in a environment so that they can continue their education without any barriers. and government should consider this situation and make a flexible law for this situation.

nothing is impossible. but our country is a demacratic and a capitalist country. noone can poke to anybodys personal affair and life to do something. but i think this is an global issue. if the huge priority is given and incentives to the population of the united states than could work.

the control of population by controlling the immirants and illigal people of the united nation sounds very political to me. but if the visas rated is dropped to zero and all the illigal immigrants are deported than of course there will be a significant change in the population of the united nation. but i dnt belive that the action of population control with this kind of action will be appropriate.

some country use involuntary population control methos too. i learn these things from one of my classmate. she told us that government mixed some kinds of chemical in the public drinking water which prevent from man and woman to have a conception.  in china forced abortion is practiced. but these things dont work in all the world and a postindustrialised country like united states.

population growth and the resource use, and pollution are directly propertional. high population high resource use. and high pollution. economy is directly affected by the population growth. because more resource is used of the nation. and deplition of the resource. it affects the ecomony of the family too. it drives them poorer and poorer. this this the main problem of the developing country that is poverty.

genetic engineering

genetic engineering is the scientific alteration of the structure of the genetic material in a living organisms. it involves the production and use of recombinant DNA and has been employed to create an bacteria that synthesize insulin and other human proteins.

I think genetic engineering a good thing because by the help of genetic engineering first human  insulin is developed for the diabetic patient. it has enabled the pharmaceutical company to make such drugs which fights against the disease efficiently.because of genetic engineering a lots of food production is being done and which has helped a lot of people from the world to purchase food for less price which is helping to eradicate hunger from the world.

• Nature is an extremely complex inter-related chain consisting of many species linked in the food chain. Some scientists believe that introducing genetically modified genes may have an irreversible effect with consequences yet unknown.
• Genetic engineering borderlines on many moral issues, particularly involving religion, which questions whether man has the right to manipulate the laws and course of nature.

i really dont worry eating genetically modified food at all. but i aprriciate eating organic food too.

genetically modified food will though harm the ecosystem of that particular area which iss one of the disadvantage of the genetic engineering. because of the new technique the fertility of the land will decrease and they have to use more chemicals and other technique. and those organisms which are responsible to make the land fertile for an example earthworm will die because the chemicals and the different plants which will affect the ecosystem.

genetic engineering is a part of a science which is from the human mind and the god is a metaphysical beliefs. so i this science and the god(metaphysical belief) do have no dycotomy. so its not playing as a god.

science and the experimentation of the new invention should be promoted by the government. if there had been any control we would have been still wondering if the moon is hot or cold. there should be a promotion and the boost should be given to the new scientific research.
