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

Hybrid

good things about hybrid cars
Improved air quality
Reduced fuel costs
Climate change influences
burning of gasoline by cars, it pollutes the air.
Drivers don't need to change their habits at all. You don't have to learn anything or do anything different to drive a Hybrid.
Less use of money
bad things about hybrid cars
Cost, it is more expensive than normal cars
Poor mileage performance

Water pollution research

Water Pollution

Water pollution is the introduction of chemical, physical, biological, agents into water that degrade water quality and adversely affect the organisms that depend on the water.

 

Types of pollution:

 

point source pollution:  Point source pollution is a pollution that is discharged from a single source.

Non point source pollution:, unlike pollution from industrial and sewage treatment plants, comes from many diffuse sources. NPS pollution is caused by rainfall or snowmelt moving over and through the ground. As the runoff moves, it picks up and carries away natural and human-made pollutants, finally depositing them into lakes, rivers, wetlands, coastal waters, and even our underground sources of drinking water.

Waste water: is water that contains waste from homes or industry. At a wastewater treatment plant , water is filtered and treated to make the water clean enough to return to a river or lake. Examples of waste water pollution: Treating wastewater, sewage sludge.

Artificial Eutrophication:  The natural process of Eutrophication is accelerated when inorganic plant nutrients , such as such as phosphorus and nitrogen, enter the water from sewage and fertilizer runoff. Eutrophication caused by humans is called Artificial Eutrophication that occurs because of the introduction of inorganic plant nutrients into a body of water through sewage and fertilizer runoff.

Thermal pollution: When the temperature of a body of water, such as a lake or stream, increases, can result. Thermal pollution can occur when power plants and other industries use water in their cooling systems and then discharge the warm water into a lake or river.

Groundwater pollution: Groundwater pollution is a type of pollution which occurs when groundwater becomes contaminated. Around the world, groundwater pollution is a very serious and costly problem, and many governments have started to take aggressive action to address it. Once contaminated, groundwater is very expensive to clean up and make usable again, and in some cases, an aquifer may be so contaminated that it has to be abandoned, which can put tremendous pressure on a community as it attempts to find a new supply of water.

Ocean pollution: Ocean pollution can kill fish, plants and animals, spoil beaches and swimming areas, and make people ill.

Ocean pollution can be prevented by banning the use of the dangerous forms of agricultural chemicals, building sewage treatment plants, using aircraft to follow and monitor ships, and using laws to stop industry dumping waste in the rivers and seas.

Water pollution in Thailand

The quality of the water in the country's major rivers, including the Chao Phraya, is worsening while the air in Bangkok has become more polluted, the 2010 Thailand Pollution Report says.

The annual report, conducted by the the Pollution Control Department and released yesterday, showed the state of the environment in Thailand deteriorated in almost all aspects.

Scientists examined water quality in 48 major rivers and freshwater sources nationwide and found that 39% of the water sources were poor quality, increasing from 33% in 2009.
