Earth hour Taking note

Earth Hour is the largest, participation event in the world.   It mobilizes people to take action on climate change, it also inspires
a global community of millions of people in 7,001 cities and towns across 152 countries to swith lights off.
The earth hour campaign was held on saturday march 23 at 8:30 to 9:30 wherever we are in the world and objectives were to protect the
planet.
In Uganda, the world’s first Earth Hour Forest was allocated with 2700 hectares of land, challenging Ugandans to fill it with 500,000
trees to fight against the 6000 hectares of deforestation that occurs in the country every month.
BOTSWANA just released a program called 'One million Trees plant for life' as part of their campaign.
And the earth hour campaign is spreading fast and hve more than 200000 commitments from individuals, governments, businesses taking
actions for our planet.
There are also famous people who is spreading the campaign Earth Hour, such as Andy, and tawainese celebrities.growing Asia, both as
an economic powerhouse and as an influential hub for global initiatives such as Earth Hour - the celebrities represent a total
population of more than 4 billion people, so their influence and engagement drives participa  tion to an often young, vibrant motivated
group of participants.

Reflection question 1 and 2

1. What does this video have to do with "environmental science" and our concept of a "sustainable world"?

This video have to do with "environmental science" and our comcept of "sustainable world" because it is obviously about environment and how its polluting our world. The video is basically about people polluting our world as technology grows. We cut down trees, use oil, and make more factories. And by doing this it's hurting our world and even us. And in order to make a sustainable world we have to start using less plastic bags, papers, phones, and other things that affects our world.

2. What can we do to prevent the "GOLDEN ARROW" as environmental science students in a school?

I've changed a lot after watching this video, it really changed my perspective on computers, plastic, papers and more. I thinked again before doing something and tried my best to save the eart so we can prevent the "Golden Arrow". I really effected me. And wanted to spread it to the school. We have to start using electronic devices to do homeworks, assignments and stop printing out papers. Also, we can make posters and spread the imformation about the serious situation that is happening right now and make a move. I think we can make a diffrence by doing this. People will start to know how serious it is and atleast think about the environment before doing something that harms the environment.

Reflection about story of stuff

I've watched "story of stuff" in ms Cindy's class. It was a video about toxic, pollution and how it affects the world. Nowadays, people can't live without money and everyone want money. But in order to be rich we need to use the natural resources to make and sell the product. So people started to cut down trees and use natural resourses and chemicals to make money. I didn't know the seriousness about the pollution before watching the video but after watching it, i felt guity. I think this video is a good video to motivate people to think again about the enviornment. From now on I'm going to think before i buy something for the environmnet and our world.

My Hybrid speech

A hybrid is any vehicle that uses two or more sources of power for propulsion.

Most hybrid cars are built in the economy car mold. Compared with cars that have similar designs and features, a hybrid car can cost 25 to 30 percent more than a comparable car,

While electric cars are expensive and can double your energy bill when re-charging at home, many early adopters say they're still worth the price, since they help the environment and reduce the need for foreign oil.

The reasons why smart people do not buy Electric or Hybrid cars are: Batteries are expensive, short lived, efficiency isn’t 100 % and the electricity is not free. Going electric you won’t decrease Air Pollution because 50 % of the electricity is produced by burning COAL. By the way a Jetta Diesel, TDI for $23000 makes 40MPG. With a full tank of Chevy Volt, driving non-stop, you make 37MPG, plus $3 or more, the price of electricity you charged 16.0-kW-hr lithium-ion, the hefty 750-pound batterypack.

Electric cars actually harm the environment more than their gas-powered counterparts in many places

the report said—they may even wind up causing more carbon emissions than gas burners. In addition, electric car batteries require toxic minerals like nickel, copper, and aluminum, increasing the potential for acidification


   

Speech Reflection

I really enjoyed doing this assignment(speech). It was something new for me and my friends. When Ms. Cindy first talked about the speech i didn't know what to do because i can't act at all. She told us to act and speak like other people (friends, singer, actor, actress).I spent more than 1 hour thinking what should i do?, Who should i be? And i chose to be Fred. He was the easiest person to follow, because he's my friend.
I was against the Hybrid car in the speech. During the speech i talked about the bad and cons about the hybrid cars. My main points were. 1. It takes long time to charge them and pollutes while charging, more than buring fuel. 2. It is more expensive than normal cars, it's hard for us to buy.
And I'm still against the Hybrid cars, As i said, It's too expensive and takes too much electricity to charge them. I think there are more ways to save the environment, such as riding bicycle, walking.

Hybrid speech notes

Jane

According to an observations done by economists , it is proven that hybrid cars will
be much more expensive to maintain because of the battery. Even though people say it will
get cheaper as hybrid cars get more common, the price would still be high for several years.
Also, Just because you're plugging in your car to power it up doesn't mean you're
automatically using clean energy.
Lily
For some, these issues in importance to saving the planet from
harmful emissions of carbon, sulfur dioxide and nitrogen dioxide—all of which are released
from combustion engine vehicles. If battery powered cars reduce emissions, they should be
produced and consumers should be enticed to buy them. Jessica
Wants a clear and beautiful world but cannot because of air pollution, so she believes that the
hybrid car is the solution to a clean and beautiful world.

Sonia
hybrid car is the solution to air pollution because use less gas/oil. Can
charge, creates less pollutions.

Alice
cure for air pollution because the hybrid car and be charge, no emission
from the car. If the car’s energy were charge with renewable energy then there would be zero
emission from the car. Air quality would be better and tax is lower because electricity taxes are
lower compare to diesel/ petroleum.

Leila
You need to charge the car for 8 hour because if
you run out the battery you need to charge it. The cars are not going to get recycle other part that gets throw away
gets into the ocean. Car manufacture needs to have the same battery, for the safety issue.


May
Hybrid car can charge which would make the air pollution better because no need that much
petroleum oil, save the money of the people because the car does not need to go and get oil
from the gas station. Have a quote about the environment.  The taxes for the car are cheaper
because more environmental friendly, the price is higher but if lots of people buy then it can be
change.


Madina
People are using hybrid car and thinking that they are
doing right helping environment. Hybrid cars are not helping.  In fact, hybrid and electric cars
are simply perpetuating our dependency on a system that is notorious for creating pollution,
and are just making us feel better about ourselves.  

Inaho
Electric cars such as hybrid car can be defined as an environmentally friendly car which is
propelled by a finely tuned gasoline or diesel engine in combination with an electric drive
which is used in city or in slow moving traffic.
The most numerous reasons which people buy electric cars and hybrid
cars are that they get better mileage than conventional cars and it means that they reduce
CO2 and exhaust gas.



Ramita
Can cure air pollution. Can help lessen air pollution. We should all think of using electric cars.
Hybrid Cars is electric car that is expensive, but will help the environment. Can be used to
protect the environment because the benefit of it is that we can save money on petroleum or
gas.

Jaspriya
In Bombay, have so many pollutions in which hybrid cars can cure.
Hybrid cars need to be charged, but in the
future there will be a charger that can charge the car for longer hours so that people do not
need to change the battery a lot.


Erin
If you add total c02 that is produced by
electric car, the hybrid car is simply not the solution. Where do you think the hybrid cars get
their energy from? They are all from pollution sources. In Norway, a study about the car have
been conducted.
Fred
will decrease the use of gasolines and the
using of oils too. By using small amount of gasoline and oil, the hybrid cars emit very small
amount of carbon dioxide per. mile. The electric cars are much more expensive, but by
calculating the usage of oil like the traditional cars, it is kind of cheaper. By using less oil, it
will reduce air pollution and reduce the rate of acidic rate. It will be an advantage for our
economic, environment, and health.

Ploy
Electric car are powered by electric batteries. It can switch the usage from batteries to
gasoline. It will be the cure for air pollutants because it is very efficient in that it can use
gasoline when they want to. Respiratory health for people would be better. Also, it would
lessen noise pollution because they are quieter. The government supports for the electric
cars. Hybrid Cars weigh smaller engine.
Nam

The car contribue to clean air in the city because they do not emit harmful air into the air such
as nitrogen oxide, or carbon monoxide. The improvement in our urban air quality will be
dramatic.

Ruchika
I am going to be talking about that electric cars are no cure for environment. Many people
would not even be able to buy the car because it is very expensive, and it can be
uncomfortable for some people. Also, it can be a waste of space for the house where there
are a lot of members in the family. I
