Heat

For the past few blog posts, we have explored the causes of climate change, the effects, the little actions we can take to keep from Earth from warming more than 2 degrees, as well as the influential environmentalists whom deserves our attention. Today, i will be talking about an effect of climate change that people normally neglect and forget about - the rise of heat related illness and disease due to climate change.

Temperature rise not only affects our environment (eg. aquatic animals and plants), it affects humans as well. This 'effect' does not encompass us sweating more due to warm weather or the weather fluctuations we experience due to climate change. We are talking about hundreds of thousands of deaths due to heat-related illness. Recalling the 2003 heat wave in Europe that killed about 20-35 thousands of people, scientists have claimed that the extreme weather was largely due to climate change, blaming the rising sea temperatures as well as other factors such as unusual conditions in the tropics. As average global temperature increases, such heat waves will definitely become more frequent, more intense and would last for a longer period of time. Human exposure to extreme heat can pose serious consequences such as heat stroke, heat rash and heat cramps. This is definitely a warning for us to take action to mitigate climate change.

What is the first disease you think about when we discuss about heat-related diseases?
For me, it has to be dengue fever, a prominent illness in Singapore due to the warm weather and humid levels. The Singaporean Government has done its part in raising awareness about dengue fever as well as how to prevent it. For other countries especially sub-saharan Africa , malaria is a disease that impacts many, especially vulnerable children and pregnant women.

Warmer temperatures allow disease-carrying insects, animals and microbes to have a higher chance of survival, even in regions where it was unable to survive before. Global rise in temperature increases the spread of  diseases such as malaria and dengue fever. Often, such heat-related diseases have no cure and can only be reduced through prevention moves.

Climate change not only impacts our environment, it also impacts us humans. It is hard for us to turn our heads away from climate change, especially with its strong impact on us and our precious flora and fauna. It is not too late for us to take action now, for Earth to be warmer by less than 2 degrees.

Coral Reefs need our help!!

In 2013, I had the chance to go to Lombok, Indonesia with my family and relatives. It was a very relaxing vacation, where we would just stay in the villa to chill, or go out to the private beach to play. It was a very memorable experience because it was my first time going to such a rural place in Indonesia. Shops on the streets were rare, street lamps were scarce and the roads were very bumpy. The route to the villa on the dark streets of Lombok still remains impactful to me today.


I also had to chance to go snorkelling with my family; it was not my first time apparently because my parents mentioned how i was very daring with ocean waters when i was young and had previous experiences of snorkelling as well. This time however, i do remember swimming with the fishes, looking at the coral reefs and exploring the sea bed. I would have to admit it was quite a terrifying experience because the snorkelling gear were very unfamiliar and the seabed was so vast it looked never ending and thus..scary. The tour guide even pointed out this abandoned ship that was left on the seabed (which i was obviously very terrified of as i let my imagination run wild).




But the experience of having electric blue, orange, yellow fishes swimming with you in the ocean was great! The coral reefs were also magnificent and beautiful, which brings me to my topic of today: coral reefs.


Coral reefs, though it only takes up 0.1% of the seabed, is actually home to 25% of all ocean species. They are an important species to the ocean ecosystem. For example, the larvae of tuna start their life cycle by living in coral reefs.
But how has anthropogenic activities affected coral reefs? Globally, we are witnessing coral bleaching spanning the tropical Pacific, Indian and Atlantic oceans due to rapid rise of temperatures. Specifically, with rise in temperatures, corals will expel the algae living within them, called Zooxanthellae. These algae living within the corals are not only responsible for the bright colours of corals, but also provide energy and nutrients for them.  Without them, the corals are bleached and will also starve and die.

Experts also predict that if ocean temperatures continue to rise at such a rapid rate , then thousands of hectares of corals will be affected within a few months, and by 2050, we might lose all our corals. We also have to take note that corals are exceptionally susceptible to extreme and rapid fluctuations of temperature, and adaptation of these species can take place only when the pace of climate change is slow.

Save our beautiful corals and do something about climate change now!
It all starts from simple actions such as switching off your lights and reducing your use of plastic bags and plastic straws. Recently, i'm also cutting down on doing take-aways so as to reduce disposables and you could do that too! I believe that small things like these can make a significant difference. You could also participate in activities that help the environment such as tree planting.

P.S/ Sign the Ben & Jerry's petition for climate justice at this link :) i'm actually really glad that such a big company is doing its part to promote action for climate change, in view of the 2015 Paris Climate Conference COP 21.  (It will only take 10 seconds of your time)

Dying to save the Earth

Just ended my tutorial related to the environment, and so many thoughts are overwhelming me as to how some people can do so much for the environment, to a level which i doubt i can ever reach. I mean, i really respect everyone who does a part to save the environment - friends who are currently vegetarian and trying to turn vegan (!!!!!) and friends who care so much for the environment that they make an effort to not use disposables deserve so much of my respect. And here i am, claiming that i am an environmental student, but doing things that i possibly can control but can't be bothered to control,  and yet these things that i 'don't bother to control' may possibly cause harm to the environment.

But anyways, after seeing and hearing about all the efforts my professor and BES course mates are doing, i will make a pledge. A pledge to cut down on disposables  such as plastic straws & plastic bottles, and a pledge to cut down my consumption on meat such as beef which causes greenhouse gas emissions.

On a side note, today's topic will be on environmentalists who have died fighting for action against climate change. I was deeply inspired by stories of Chico Mendes and Dian Fossey, both being figures which have been discussed in my lessons, and have been very prominent people who stood up for the environment, and sacrificed their lives in the process of it.



In a short summary, Francisco Alves Mendes Filho, in short Chico Mendes, was a rubber tapper. Under pressure by ranchers who were going to cut down trees in the Amazon rainforest, he stood up against them and fought for the Amazon rainforest to be preserved. However, though his intentions were good for the environment, there were others (loggers, ranchers etc.) who thought otherwise. He was assassinated by a rancher not long after his 44th birthday, on December 22, 1988.

Dian Fossey on the other hand was someone who strongly opposed to poaching and ecotourism of gorillas, a species that she had spent time doing extensive research on. She established the Digit Fund so as to raise money for her conservation and anti-poaching. However, she was murdered in 1985, a case which still remains a mystery till today.

I also did some research on a particular environmentalist, Obede Loyla Souza, who was also killed after trying to protect the Amazon forest. According to guardian, Souza had an argument with loggers who were trying to extract wood in the Amazon rainforest. The act of harvesting wood in that region filled with Brazil's nut trees was illegal. However, though the group of loggers could have been dangerous (which they later proved to be), Souza remained firm in his decision and fought with the loggers in hope to stop them from illegally extracting wood from the forest.
He was then killed outside his home in Brazil. It was one of the many murders that occurred to environmentalists over land use and logging in the Amazon Forest. Threats from ranchers, loggers and farmers have also been made to many activists so as to prevent them from speaking up.

Though Obede Loyla Souza was not as influential and popular as Chico Mendes in terms of his anti-logging acts, he proved to us that anyone can make a difference to our environment. He was just a regular and ordinary citizen, just like us. It also shocked me that many environmentalists are being killed because they want  to save the planet - aren't these environmentalists doing it for us, and for the future generations -our kids, our grandsons and granddaughters? There is nothing fundamentally wrong with environmentalists speaking up for the environment - so why are people harbouring evil thoughts on these people? I guess governments, companies and other individuals have to realise how inspiring all these environmentalists were, for they are making an effort to make a positive impact on the Earth, unlike most people who are only concerned about their personal comfort.
I am just hoping for the better, hoping that all these murders and threats will not deter people from speaking out for Mother Earth. One day, i hope i'll be as influential as these people, and that more activists, especially in Singapore, will speak up in view of the rising environmental movement

P.S. / Thinking of whether i should symbolically adopt a tiger from the WWF organisation ( though i would really really like to physically adopt a tiger hahaha).
