Global Warming Impact – Loss of Coral Life in The Great Barrier Reef

In the past couple of days, national and international news sources have been reporting that global warming is causing irreversible damage to the Great Barrier Reef. Known as the world’s largest coral reef system with over 2,900 individual reefs, The Great Barrier Reef has reportedly lost half of its coral since 2016 according to The Atlantic. Located in the Coral Sea, off the coast of Queensland, Australia, The Great Barrier Reef is well-known for being the world’s largest single structure made by living organisms and can be seen from outer space. It supports a wide diversity of marine life – including whales, sharks, turtles, and crustaceans.

However, in most recent years, damage to the reef has reduced the size of this natural coral system and has also radically altered the mix of its marine species according to scientists. In a New York Times article published earlier today, researchers have noted that nearly one-third of the reef’s coral were killed when ocean temperatures spiked in 2016, as a result of global warming. The underwater heat wave that damaged huge sections of the Great Barrier Reef was so severe that scientists have reported that the natural wonder will probably never look the same again. Once labelled by CNN as one of the seven natural wonders of the world, the Great Barrier Reef’s entire ecological identity has changed forever due to the conclusion that losses in certain species has irreversibly damaged the make-up of this extraordinary ecosystem.

The director of a government-funded center for coral reef studies at James Cook University, Terry P. Hughes,  is also the lead author of a study currently being done on the deteriorating state of the Great Barrier Reef. Hughes has reported that in 2016 alone, “about 30 % of the Great  Barrier Reef’s corals were lost, with the most severe damage in the isolated northern sector”. Last year another ocean heat, took another 20% of the corals, according to Hughes.

 The back to back record-breaking marine heat wave is an “unprecedented” event in the reefs recorded history according to researchers and scientists studying the effects of global warming on coral reefs. The higher temperatures create a dilemma for the reefs because the excessive heat results in a massive coral bleaching event, according to Scientific American. “Healthy corals have a symbiotic relationship with tiny algae, which live inside them and give them bright colors. But when corals experience heat stress, they expel their algae, turning a bleached white color in the process.”

Although bleaching isn’t necessarily a death sentence for corals, extremely warm periods can kills reefs before their algae can get a chance to regrow and recover. Researchers have concluded by examining the Great Barrier Reef, that some coral species are better at “weathering heat stress” than others. Surveys done on the The Great Barrier Reef have suggested that many areas have seen a decline in fast-growing species, such as staghorn and tabular corals, with slower-growing, simpler species being left behind. Researchers have stated that this is a perfect example of natural-selection at work.

As a reef structure that is composed of and built by billions of tiny organisms, the conclusions being drawn about the Great Barrier Reef presents both good and bad news. On one hand, the survival of “slower-growing , hardier coral species” suggests that there’s still a future for the reef, although it may look different from what it was in the 20th century. On the other hand, many of the surviving corals are much simpler due to their physical structure compared to their “faster-growing” counterparts, which were notable for their “complex, branching 3-D designs.

As a World Heritage Site since 1981, The Great Barrier Reef is in danger of never fully recovering from the recent rise in global temperatures that has shown to have a negative impact on ecosystems around the globe. According to researchers, prospects for a full recovery are slim. “Even if some of the faster-growing species started to make a comeback, it would still take at least a decade for them to return to their previous levels,” says sources quoted in Scientific America’s most recent article on the future of the Great Barrier Reef. According to many in the scientific community in Australia and around the globe, it’s more likely that more heat waves will occur in the meantime, causing more damage before the reef has fully rebuilt itself.  With an area of 134,634 mi², the future of the Great Barrier Reef relies on the global response to climate change and on the research used to discern the best course of action for saving one of Earth’s most beloved seven natural wonders.

Sustainable Living: Environmentally Clean

By: Breanna Gordon

Keeping a clean-living space can bring about an immense amount of stress relief. I understand that cleaning can be very overwhelming with all of isles of products claiming to do the same things. Which do you use?  None! It is not necessary to spend money on chemicals that can bring about harm to not only your health, but to the environment.

Recently, I moved into an apartment that needed a lot of TLC in the bathroom. Being that I am new to housekeeping I went straight to my aunt for advice. Surprisingly she suggested white vinegar to be one of my staple products.

This led me to investigate other safe cleaning products and implement them into my cleaning routine. Here’s how I get things environmentally clean.

After an old shirt is unwearable, I cut the shirt into squares and use the squares as towels. I fill a bowl with water and squeeze any excess water from my DIY towel into a sink. White vinegar is used to clean all the surfaces in my bathroom. I pour vinegar into a glass spray bottle and spray as needed. Once the vinegar sits for a minute or two, I take my DIY towel and wipe the vinegar away.

For any grout that builds up on tile I use baking soda and water. I place baking soda and water in a bowl and mix it with an old toothbrush until it becomes a paste. I apply the paste to the grout and use the toothbrush to scrub in between the tile. Once the scrubbing is complete I wipe the tile down with my DIY towel.

To clean my mirrors and windows I also use white vinegar. I spray the vinegar onto my mirrors and windows and use old papers to wipe the vinegar away.  This leaves the mirrors and windows sparkling clean.

If the smell of vinegar is not to your liking, place orange peels in the spray bottle. After two weeks the vinegar will adopt a citrus flavor. You may also use your favorite essential oil to satisfy your smell preference.

The Problem with Palm Oil – Deforestation & Beyond

In grocery stores around the world, consumers are able to purchase a very controversial product that directly contributes to global climate change. Palm oil, which is used by many indigenous cultures around the world, can also be found in nearly half of all supermarket products. In a recent Global Citizen article published earlier this week, Chris Gelardi explains that because palm oil is in such high demand across the globe, top producers in Southeast Asia have been deliberately clearing their tropical forests by setting fire to them in order to make room for palm oil plantations.
This illicit deforestation decimates the habitats of countless species, including the orangutan, which has lost 80% of its habitat over the past 20 years according to the Orangutan Project.

How much has the sea level risen? How can we stop climate change?

By: Selena Rodriguez

It could be scary to think about how much our sea level has risen over the years, but it is important to be aware so we all realize that change needs to happen.

To answer this question, I did a little research and was able to get information from NASA. According to NASA, our global average sea level has risen about 7″ over the past 100 years. Now this might not seem like a big deal, but let me be the one to tell you that it is. And the reason that this is happening is because of climate change. I really do believe there is climate change and that it has been happening and will continue to happen if not taken seriously. Of course there are those that believe it is unreal or just not possible, but one thing is for sure; numbers don’t lie.

As noted by NASA, sea level rise is based on two main factors that relate to global warming; the expansion of seawater as it warms and the added water from melting ice sheets. Climate change, which is also known as global warming, is nothing new but the question is what can we do to stop climate change?

This question is a littler harder to answer not because there aren’t solutions, but we need the support from those who have the “power” to hear our voices and make our concerns known to those who can set better solutions or ones that we have not tried.

If you click here, you will see that NASA explains that they are not trying to set up a climate policy, but rather provide scientific data to make sure that we, as well as the world, understands climate change that way we can figure out how to fight back.

If we all become aware of what is happening not just within our region but all regions, then we can all work together to save our precious Earth.
