This past summer I visited Costa Rica. The first thought you
have after getting off of a four-hour plane ride is “wow, boy is it hot.” And
it is, it’s very stuffy and humid and uncomfortable as you wade through the
thick air into an air-conditioned tourist van. After that, your next analysis
of the tropical country comes to you as you peer out of the windows of that air
conditioned tourist van: Costa Rica is green. And finally, after you’ve spent a
couple of days there, you’re last observation: it rains a lot.
This is an observation I had about halfway into my two-week
trip. It rained at least once a day, at the same time everyday, with some
“unscheduled” rains mixed in. Any person coming from a normal climate in the
United States would come to the same conclusion, that yes, Costa Rica rains a
lot. Yet, even as much as I had thought it rained while I was there, it wasn’t
enough. Around 2008, concerns were
voiced that the amount of rainfall in Costa Rica was diminishing, and those
numbers have only gone down in recent years. If in fact, rainfall continues to
decrease, this would have major negative effects on the country environmentally
and economically.
Certain species of the country depend on having an excess of
water for mating season; an example: the golden toad. Male golden toads gather
in puddles of water left over from heavy rainfalls, and wait for female mates
to come, where they mate, lay their eggs, and the lifecycle continues. But over
the past three decades Costa Rica has started seeing a decrease in rainfall,
and as a result, we have seen a direct correlation in the decrease in the
golden toad population. The golden toad is one small example and its
disappearance has little impact on the rest of the ecology but if Costa Rica
continues to have insufficient rains more species will follow and further
disrupt the rainforest’s balance.
The reduction of rainfall in Costa Rica not only has environmental
implications but it also affects the economy, which relies on tourism and
agriculture. As the rainforest dies, Costa Rica will become a less popular destination,
decreasing the tourism industry, which according to Princeton University’s
website, accounts for almost $2 billion a year. The loss of this major input of
money into the already small economy would devastate Costa Rica. Moreover, many
farmers are dependent on the annual flooding of their fields to grow rice. Less
rain means less floods which leads to failing rice crops and eventually to
further destruction of the economy.
If this isn’t enough it gets worse. Costa Rica is one of the
greenest countries in the world, producing an estimated 80+ percent of its energy
from hydroelectric power. Rivers and lakes producing this power are shrinking
due to the decrease in rainfall. Less water will lead to lack of energy in the
future, which inherently creates its own problems. The point is, diminishing
rainfalls in Costa Rica have large and lasting impacts and not just on the
environment. But the question is what can we point to that causes this climate
change? I’m sure most of you already know where I’m going with this: Global
Warming.
The alarming deterioration of the Costa Rican environment is
part of larger climate change impacts worldwide: the shrinking of the Great
Barrier Reef in Australia, the recession of the glaciers in Canada, the melting
of the polar ice caps, to name a few. To most of us, these seem like problems
far away from home that we don’t need to worry about, but we have problems here
in the United States too; for example the California drought this summer. In
fact, multiple studies indicate it was the worst drought California had seen in
1,200 years. Adding on top of that, problems elsewhere can still affect us. The
melting of the ice caps will lead to an estimated 20 feet rise in sea levels
worldwide, which would submerge many coastal areas including most of Manhattan,
proving this isn’t a problem we can’t ignore.
Further consequences of Global Warming include, well, Global
Warming. All ten of the hottest years recorded in history, have occurred in the
last two and a half decades, as Al Gore points out in his documentary, “An
Inconvenient Truth”. With
temperatures increasing, our polar ice caps are melting, further increasing the
Earth’s temperature because ice reflects light and heat, while water absorbs
it. In addition, the disappearance of large ice sheets is creating problems for
many species, such as polar bears, which use them to rest in between long
stretches of swimming. With nowhere to rest, we are starting to see the first
cases ever of Polar bears drowning.
Not only are polar bears going extinct, so are all types of species.
We are currently in the second greatest period of extinction since the
dinosaurs, and last time I checked, that didn’t go too well for them. The World Wildlife Foundation says that
between .01 and .1% of all species go extinct a year, which, depending on how
many species there are (scientists have different estimates), is anywhere
between 200 and 100,000 species a year. Now maybe we shouldn’t be alarmed,
there have, of course, been five other periods of mass extinction in geological
history, but none could be solely attributed to one species like this one can
be attributed to humans.
In 2006, when Al Gore released his movie “An Inconvenient
Truth” there were a lot of people who “didn’t believe” in global warming, or
denied it, but today most people have accepted it, so I’m guessing my speech so
far has only defined the magnitude of the effects it has had. Still, it is
clear that climate change is a problem and it will only get worse. Yet, there
are still those who believe Global Warming is not a problem worth fixing, or
that global warming is no longer fixable.
For starters, Global Warming is a problem worth fixing. My
first appeal to everyone would be just out of sentimental value. I’m not sure
how many of you have been to a rainforest, or seen glaciers, or explored a
national park (or any other exotic place), but I and others who have done these
things can assure you that it is one of the most amazing things you will ever
do. And as Global Warming and its worldly impacts increase, the opportunities
and availability of these experiences decrease. So to everyone who truly loves
this world and wants to continue to be able to experience the diversity and
wonderfulness of nature, I implore you to fight to save earth, and helping end
Global Warming.
Now there are some to whom the sentimental argument doesn’t
matter, who don’t care about nature, but only about the well being of the
economy and their financial state. And to them I would point out that what is
good for nature is good for the economy. According to Al Gore in his
documentary, the car companies that started making more energy efficient and
environmentally friendly cars (Toyota and Honda) did exceedingly better than
those who didn’t (Ford and GM). Likewise, if we can find a way to harness solar
power more efficiently, it would be a much cheaper energy than the fossil fuels,
which are our most common energy today.
Furthermore, using the finite amount of fossil fuels in
existence is leading the economy towards turmoil. We, as a people, are not
looking for other sources of energy hard enough, and as a consequence, when the
fossil fuels run out, which scientists estimate will happen this century, we
will be left with no alternative forms of energy. We’re pushing our economic
woes down the road, and piling them up in a landfill (such as we do with our
trash), that years later will come back to hurt us more than we could ever
imagine. Whether you decide global warming is an issue worth spending time and
money to solve because it helps the economy or because you love nature, it is
an endeavor worthwhile for everyone.
And for those of
you who think Global Warming is an unsolvable problem, its not, and there are
many steps you and I can take to help reduce it. The obvious solution is to try
to help thin out the ozone layer (which is trapping heat on Earth) by reducing
our “carbon footprint”. Anyone can
do this personally by having a more efficient car, buying less stuff, recycling
more, using LED light bulbs as well as many other solutions that can be found
on the Union of Concerned Scientists website (uscusa.org). If every United
States citizens made these efforts, our carbon emissions could be reduced by up
to 20%.
The best solution to global Warming would be to find
alternative energy sources such as wind power or hydrogen fusing and you can
help this cause. There are ways to donate money for research to be done, or you
can lobby for this research to be important. If we can show our
national leaders that finding sustainable energy is important to us, they will
listen. It will change their agendas and we can have the funding and
intelligence and full support of the United States in curing the Earth. I know
it seems impossible to solve this enormous problem but in the words of Margaret
Meade, “never doubt that a small group of thoughtful committed citizens can
change the world; in fact it is the only thing that ever has.” So I leave you with this final thought,
this final plea: don’t ignore this
speech and don’t ignore global warming. Go home today and make the changes in
your life. Tell others to make the change; just get the word out there so that
ten or twenty or thirty years down the road, we’ll be well on our way to
overcoming Global Warming, and so when one of you goes to Costa Rica, you too
will think “wow, it sure does rain a lot.”
