Gas Cars? - Persuasive Essay
We use them everyday in America, yet it help kill the environment every time. They
cause others to inhale potentially dangerous chemicals in the air. It’s breaking down
the ozone layer, causing global warming to occur. Gas cars destroy the planet every
time we start them. We need an alternative source of energy for our own good. The
only other know portable energy we have that keeps its surroundings clean is the
battery.
There are some large disadvantages to using an electric car opposed to a gas car.
The cost of batteries is much higher than gas, and you can’t get very far even on a
full batter (40 or more miles). But: Technology is always advancing. Discoveries are
being made
Incinerator Essay
To you, incinerators generate a lot of toxic pollutants, but if you research this topic
more closely you will see that most of the toxic pollutants don’t reach the
atmosphere.
Landfills are the main destination for Canadian solid waste. In 1998 nearly 21
million tones of waste was disposed of in 767 landfills, and in 45 incinerators across
the country. Landfill sites generate over a quarter of the methane emissions caused
by human activity in Canada, sending 1.2 million tones of this potent greenhouse gas
into the atmosphere each year. Because the global warming effect of methane is 21
times greater than that of carbon dioxide, this is the equivalent of greenhouse gas
emissions from more than six million cars – or 40 per cent of all the passenger
vehicles in the country.
While innovative technologies have been developed to capture this gas for use as fuel
in heating buildings or generating electricity, landfills are not a long term solution
to waste management for future generations. Innovative programs to reduce and
ultimately eliminate the need to use valuable land as garbage dumps are what is
needed to ensure a continuation of the quality of life Canadians have enjoyed.
A Leader in Converting Waste into Energy Strict
An Environmental History of theTwentieth-century world-
Most of the time, we can hear bad or alarming news concerning the environment.
The ozone hole is growing, global warming is worse than before, more and more
species are threatened with extinction. However, sometimes, some people -like the
author, J.R Mc Neill- tries to show us that ‘environmental changes usually are good
for some people and bad for others’ and that there might be a way out.
With his work, J.R Mc Neill, made a really surprising job. Indeed, we are not used
to study the history of the twentieth century through its environmental history, we
most often tell the history of the twentieth century through its wars, its economic
and political changes, and trying to explain this history with such a different point
of view, could be a very challenging and interesting task. Through his book, the
author tells us lots of anecdotes, explanations, show us different kind of documents.
This book is really based on an exhaustive research, and it seems to be really
difficult to sum up all these things in a paper.
In first the author argues that to a degree unprecedented in the human history, in
the twentieth century, we have been moving Earth: polluting the atmosphere, the
water….Indeed, under the pressure of human activity, the
