New Monitoring Technologies Promise To Let Marine Wildlife Off The Hook

Published

on

Conservation scientists are calling for new approaches to biodiversity monitoring to reflect the creation of a global network of large marine protected areas, in research published today by the Zoological Society of London (ZSL) and University of Western Australia (UWA), funded by the Australian National Environmental Research Program (NERP) and the Bertarelli Foundation.

The research was published today in the journal Biological Reviews and was funded by the Australia’s National Environmental Science Programme and the Bertarelli Foundation.

By closing large tracts of ocean to fishing, the creation of marine reserves in locations including Chagos, Chile and New Zealand is removing what was traditionally the only reliable source of data on fish populations available to managers in these regions, highlighting a clear need for new non-lethal approaches to monitoring.

The ZSL/UWA report suggests harnessing emerging technologies including underwater action cameras in tandem with established techniques like acoustic echo-location to provide non-lethal monitoring of wildlife within these vast new ocean sanctuaries. The study’s findings were based on extensive literature review, combined with field trials of technological approaches in the Indian Ocean’s 640,000 km2 Chagos Marine Reserve, the enforcement of which has been supported by the Bertarelli Foundation.

Commenting on the research, lead author Dr Tom B. Letessier from ZSL said: “Species including migratory sharks, tunas and billfish are amongst the most iconic marine predators on the planet, yet as our review demonstrates, the collapse in their numbers since the 1950s now also make them some of the most threatened.

“Most of what we know about these animals comes from decades of commercial fishing records, which have historically been the only data available for fisheries management. Recent positive steps to create large marine reserves that exclude commercial fishing have had the unintended consequence of reducing the availability of these data, thereby requiring new approaches to measurement. In addition to establishing trends in large marine reserve size and coverage, our study reviews existing methods used in the absence of fishing and demonstrates non-lethal ways to complement them.”

Expanding on the significance of the study, co-author Professor Jessica Meeuwig from UWA’s Oceans Institute explained: “While the role of marine reserves in protecting coastal ecosystems is now well-understood, far less is known about the impact of these large reserves on highly migratory species like sharks and tuna, which may roam across entire ocean basins. If we are to demonstrate the success of these new large sanctuaries, we need to think outside the box to devise effective, non-lethal monitoring techniques in areas where fishing is banned.”

Other announcements following on the heels of Chagos include the 620,000 km2 Kermadec Ocean Sanctuary, announced by the New Zealand government in September 2015, and the even larger 631,368 km2 Easter Island Marine Reserve, plans for which were unveiled by the Chilean government the following month. With similar projects set to follow, the urgent need for new, technology-driven approaches to non-lethal monitoring of ocean biodiversity is clear.

Project donor Ernesto Bertarelli of the Bertarelli Foundation said: “Advances in the sophistication and affordability of technology give us the opportunity to monitor and understand marine life within protected areas as never before. This is crucial, not just to help monitor the overall health of the ocean but to better understand the role of MPAs in building wider resilience. That’s why we are so excited to support this work.”

2017 Was the Most Expensive Year Ever for U.S. Natural Disaster Damage

Natural Disaster Damage

Devastating natural disasters dominated last year’s headlines and made many wonder how the affected areas could ever recover. According to data from the U.S. National Oceanic and Atmospheric Administration (NOAA), the storms and other weather events that caused the destruction were extremely costly.

Specifically, the natural disasters recorded last year caused so much damage that the associated losses made 2017 the most expensive year on record in the 38-year history of keeping such data. The following are several reasons that 2017 made headlines for this notorious distinction.

Over a Dozen Events With Losses Totalling More Than $1 Billion Each

The NOAA reports that in total, the recorded losses equaled $306 billion, which is $90 billion more than the amount associated with 2005, the previous record holder. One of the primary reasons the dollar amount climbed so high last year is that 16 individual events cost more than $1 billion each.

Global Warming Contributed to Hurricane Harvey

Hurricane Harvey, one of two Category-4 hurricanes that made landfall in 2017, was a particularly expensive natural disaster. Nearly 800,000 people needed assistance after the storm. Hurricane Harvey alone cost $125 billion, with some estimates even higher than that. So far, the only hurricane more expensive than Harvey was Katrina.

Before Hurricane Harvey hit, scientists speculated climate change could make it worse. They discussed how rising ocean temperatures make hurricanes more intense, and warmer atmospheres have higher amounts of water vapor, causing larger rainfall totals.

Since then, a new study published in “Environmental Research Letters” confirmed climate change was indeed a factor that gave Hurricane Harvey more power. It found environmental conditions associated with global warming made the storm more severe and increase the likelihood of similar events.

That same study also compared today’s storms with ones from 1900. It found that compared to those earlier weather phenomena, Hurricane Harvey’s rainfall was 15 percent more intense and three times as likely to happen now versus in 1900.

Warming oceans are one of the contributing factors. Specifically, the ocean’s surface temperature associated with the region where Hurricane Harvey quickly transformed from a tropical storm into a Category 4 hurricane has become about 1 degree Fahrenheit warmer over the past few decades.

Michael Mann, a climatologist from Penn State University, believes that due to a relationship known as the Clausius-Clapeyron equation, there was about 3-5 percent more moisture in the air, which caused more rain. To complicate matters even more, global warming made sea levels rise by more than 6 inches in the Houston area over the past few decades. Mann also believes global warming caused the stationery summer weather patterns that made Hurricane Harvey stop moving and saturate the area with rain. Mann clarifies although global warming didn’t cause Hurricane Harvey as a whole, it exacerbated several factors of the storm.

Also, statistics collected by the Environmental Protection Agency (EPA) from 1901-2015 found the precipitation levels in the contiguous 48 states had gone up by 0.17 inches per decade. The EPA notes the increase is expected because rainfall totals tend to go up as the Earth’s surface temperatures rise and additional evaporation occurs.

The EPA’s measurements about surface temperature indicate for the same timespan mentioned above for precipitation, the temperatures have gotten 0.14 Fahrenheit hotter per decade. Also, although the global surface temperature went up by 0.15 Fahrenheit during the same period, the temperature rise has been faster in the United States compared to the rest of the world since the 1970s.

Severe Storms Cause a Loss of Productivity

Many people don’t immediately think of one important factor when discussing the aftermath of natural disasters: the adverse impact on productivity. Businesses and members of the workforce in Houston, Miami and other cities hit by Hurricanes Harvey and Irma suffered losses that may total between $150-200 billion when both damage and sacrificed productivity are accounted for, according to estimates from Moody’s Analytics.

Some workers who decide to leave their homes before storms arrive delay returning after the immediate danger has passed. As a result of their absences, a labor-force shortage may occur. News sources posted stories highlighting that the Houston area might not have enough construction workers to handle necessary rebuilding efforts after Hurricane Harvey.

It’s not hard to imagine the impact heavy storms could have on business operations. However, companies that offer goods to help people prepare for hurricanes and similar disasters often find the market wants what they provide. While watching the paths of current storms, people tend to recall storms that took place years ago and see them as reminders to get prepared for what could happen.

Longer and More Disastrous Wildfires Require More Resources to Fight

The wildfires that ripped through millions of acres in the western region of the United States this year also made substantial contributions to the 2017 disaster-related expenses. The U.S. Forest Service, which is within the U.S. Department of Agriculture, reported 2017 as its costliest year ever and saw total expenditures exceeding $2 billion.

The agency anticipates the costs will grow, especially when they take past data into account. In 1995, the U.S. Forest Service spent 16 percent of its annual budget for wildfire-fighting costs, but in 2015, the amount ballooned to 52 percent. The sheer number of wildfires last year didn’t help matters either. Between January 1 and November 24 last year, 54,858 fires broke out.

2017: Among the Three Hottest Years Recorded

People cause the majority of wildfires, but climate change acts as another notable contributor. In addition to affecting hurricane intensity, rising temperatures help fires spread and make them harder to extinguish.

Data collected by the National Interagency Fire Center and published by the EPA highlighted a correlation between the largest wildfires and the warmest years on record. The extent of damage caused by wildfires has gotten worse since the 1980s, but became particularly severe starting in 2000 during a period characterized by some of the warmest years the U.S. ever recorded.

Things haven’t changed for the better, either. In mid-December of 2017, the World Meteorological Organization released a statement announcing the year would likely end as one of the three warmest years ever recorded. A notable finding since the group looks at global land and ocean temperature, not just statistics associated with the United States.

Not all the most financially impactful weather events in 2017 were hurricanes and wildfires. Some of the other issues that cost over $1 billion included a hailstorm in Colorado, tornados in several regions of the U.S. and substantial flooding throughout Missouri and Arkansas.

Although numerous factors gave these natural disasters momentum, scientists know climate change was a defining force — a reality that should worry just about everyone.

Environmentally Sustainable Furniture for Dummies

Published

We probably don’t think a great deal about our furniture choices. I know that I tend to just buy whatever looks pretty, seems functional and fits my budget. That usually means a trip to a few showrooms and big warehouse stores, like Ikea.

But we have a responsibility to the planet. We can do better. There are three major ways that our furniture can help the environment:

  1. Purchase used and/or recycled furniture and extends the lifecycle of precious materials.
  2. Source furniture that is free of environmentally unsustainable products.
  3. Choose furniture that doesn’t require electricity – opting for manual transitioning.

By investing in environmentally sustainable, high-qualify furniture, you’ll be able to pass down items from generation to generation. This will save your heirs on the cost of furnishing their own home, and help to protect the environment from wasteful fad furniture that only lasts a season or two.

Natural and Recycled Furniture Materials

If you absolutely love the look of wood furniture, search for environmentally sustainable products. For example, locally sourced wood or bamboo can easily be replenished without requiring excessive international harvesting of precious woods that harm the environment.

Sustainable wood products are only sourced from companies and locations that have the ability to quickly replace harvested wood – providing a responsible resource for generations of manufacturers and consumers.

Recycled furniture can either be a gently used item from someone else’s home, or a new piece of furniture that’s been used from reclaimed sources. You’ve probably seen examples of this at your local park – cities are increasingly using recycled materials to create benches and picnic tables.

But recycled materials don’t have to feel rough or rustic. Items made from recycled wood are readily available for order online or in-store. And believe it or not, electronic waste can be reclaimed and crafted into beautiful pieces of modern furniture.

The only limitation on recycled furniture design is the imagination of the creator. If you want to do it yourself, check out this DIY recycled furniture pinterest board!

Avoid Harsh Chemicals that Harm the Environment

Did you know that many cushions are made of highly-flammable polyurethane? Furniture manufacturers help keep our butts out of the hot seat by treating the materials in cushions with fire-retardant toxins. Unfortunately this padding breaks down overtime and the dust is both toxic to humans and the environment.

There are multiple lines of eco-friendly furniture that avoid the use of flammable polyurethane – often substituting with organic cotton. Just understand that you’re going to be in for a bit of sticker shock – eco-friendly furniture, when purchased new from major brands, gets pricey.

If you can’t afford the pricetag, I recommend finding used furniture from the same product line. There are a ton of websites dedicated to helping eco-friendly consumers find used organic, responsibly sourced products – and that includes furniture.

You’ll also want to stay away from faux leather. Furniture made from pleather and other leather substitutes are heavily treated with chemicals. That’s never a win.

Hypo-allergenic stuffing, combine with traditional leather might be a decent compromise if you have to have the leather look to tie a room together. But be conscious of the fact that tanning is not an environmentally friendly process, so try to limit these materials in your design.

In conclusion, it’s up to you how crazy you want to go. I think that as long as you stay with used furniture, you’re on the right track – even if it isn’t environmentally perfect, it’s at least a sunk cost for the environment – the damage has been done and you’re extending its useful life. But I think the most important takeaway here is buy quality items that you can pass down to your next generation – if that means spending more on higher quality new items that are sustainably sourced, so be it.
