How 14 Days In The Yucatan Made Me Realize The Value of Planet Earth

From a post by Shawna Coronado on her blog Gradening Nude on Chicago Now:

. . . My family and I took the eco-journey of a lifetime in 2009 into the jungles, caves, and ocean of the Yucatan Peninsula in Mexico. Above you see me getting ready to zipline across a jungle - note the giant grin - it was a blast! I wrote and posted a blog every day for fourteen days about our journey using greening and eco-nature information as a tool to educate readers about environmental concerns in the world. . . .

Understanding the fact that we impact all of the world, not just our little corner is so important. For example, areas of coral are dying out in the Yucatan from our fertilizer run-off. If the chemicals do not go down into our water aquifer, they are whooshed out through the storm water system. All those chemicals then react with ocean life - ultimately causing green blooms and death where ever the chemicals settle. This is disastrous for coral.

Who taught me that? An amazing man in Akumal, Mexico named Paul Sanchez- Navarro who is the Director of Centro Ecological Akumal (Photo to the right). He explained how nearly one quarter of all marine species are believed to depend on coral at some stage of their development. Many fish live their entire lives on reefs, while others use them as nurseries; if the coral dies out it is assumed the fish will too. The economic impact of losing coral is also significant - in the billions of dollars worldwide.

There were so many questions I wanted answered when I returned from the trip. What will happen if we are unable to provide fish for the world to eat? Will people starve? Without the coral and fish, millions of people will lose their jobs and be unable to support themselves. Without smaller fish which inhabit the coral reefs will all the larger fish die such as tuna and shark - the very same fish we use to feed our nation?

We went to jungles, beaches, caves, and protected eco-parks throughout the Yucatan Peninsula area and experienced some incredible things in nature, but one of the most powerful messages I saw everywhere we went is that you have an impact on planet earth. What we do here in the U.S. directly touches the rest of the world - the water supply issue is just the beginning.

Make a difference for planet earth - start paying attention to the chemicals, fertilizers, and products you use at home that might be making a difference half-way around the world.

Shawna Coronado says Get Healthy! Get Green! Get Community!

To save the planet, save the seas

From an op ed by Dan Laffoley, the marine vice chairman of the World Commission on Protected Areas at the International Union for Conservation of Nature and the principal specialist for marine at Natural England, in the New York Times:

For the many disappointments of the recent climate talks in Copenhagen, there was at least one clear positive outcome, and that was the progress made on a program called Reducing Emissions From Deforestation and Forest Degradation. Under this program, key elements of which were agreed on at Copenhagen, developing countries would be compensated for preserving forests, peat soils, swamps and fields that are efficient absorbers of carbon dioxide, the primary heat-trapping gas linked to global warming.

This approach, which takes advantage of the power of nature itself, is an economical way to store large amounts of carbon. But the program is limited in that it includes only those carbon sinks found on land. We now need to look for similar opportunities to curb climate change in the oceans.

Few people may realize it, but in addition to producing most of the oxygen we breathe, the ocean absorbs some 25 percent of current annual carbon dioxide emissions. Half the world’s carbon stocks are held in plankton, mangroves, salt marshes and other marine life. So it is at least as important to preserve this ocean life as it is to preserve forests, to secure its role in helping us adapt to and mitigate climate change.

Sea-grass meadows, for example, which flourish in shallow coastal waters, account for 15 percent of the ocean’s total carbon storage, and underwater forests of kelp store huge amounts of carbon, just as forests do on land. The most efficient natural carbon sink of all is not on land, but in the ocean, in the form of Posidonia oceanica, a species of sea grass that forms vast underwater meadows that wave in the currents just as fields of grass on land sway in the wind.

Worldwide, coastal habitats like these are being lost because of human activity.

What makes the Mesoamerican Reef extraordinary

From a description of the work of the WWF in the Mesoamerian
Reef:


The jewel of the Caribbean Sea, the Mesoamerican Reef is a rich tapestry of fringing reefs, atolls,patch reefs, sea grass pastures and mangrove forests. An ancient natural system dating back 225 million years, it acts as a natural barrier against severe storms for Mexico, Guatemala, Belize and Honduras, and its presence is vital to the survival of many plants and animals as well
as humans.

As the most important barrier reef in the Western Hemisphere and the second largest in the world, the Mesoamerican Reef provides shelter for fascinating species, such as the mammoth whale shark and the endangered salt water crocodile. It is also home to one of
the world’s largest populations of manatees.

The place. A large mosaic of ecosystems, the Mesoamerican Reef covers nearly 115 million acres—from the northern end of the Yucatán Peninsula in Mexico and the Caribbean coasts of Belize and Guatemala, to the Bay Islands in northern Honduras. It includes ocean habitats, coastal zones, tropical and cloud forests, and watersheds that drain the Caribbean slope.

The species. The Mesoamerican Reef hosts more than 65 species of stony coral and more than 500 species of fish—including commercially-vital grouper, snapper and spiny lobster. It also provides refuge for sea turtles that feed and nest along the shoreline. Its watershed is home to jaguars, howler monkeys and birds such as the quetzal.

The people. More than two million people live in the coastal communities that span four countries. This population of great cultural and ethnic diversity depends on economic activities linked to coastal and marine resources, such as fishing and tourism. The region is also experiencing rapid population growth and increased exploitation of land and resources.

Mexico's conch shells yield clues into effects of warming

From an article distributed by Agence France-Presse (AFP):

CANCUN, Mexico, Dec 21 (AFP)- Divers plumb the turquoise depths of ocean waters some 100 kilometers south of this vacation paradise, in search of the distinctive queen conch shell prized by vacationers and souvenir-seekers.
These divers were not searching for a Mexican holiday keepsake however.

They were scientists conducting vital research into the reach of global warming over the centuries in this fragile aquatic ecosystem.

The researchers were attaching electronic probes to about 60 specimen of the queen conch, also known by its marine name Eustrombus gigas, a species of large, edible sea snail native to these waters.

The scientists, who were seeking more information about the impact of climate change off of the Yucatan Peninsula, said the data they are collecting, they said, can provide information yielding information dating back to pre-Columbian times.

"Our findings will not only be relevant for the future of this species, but for mapping the future of global warming" said Dalila Aldana, lead investigator on the project.

The oversized pink conch, which have seen their habitat seriously degraded in the past decade and a half by global warming, are being tagged with computer sensors to monitor their eating and reproductive patterns. . . .

The research aims to identify the temperature variations over time and to determine how these are manifested in the conch shells and how they impact the viability of the mollusks.

Sea level rise impacts on the Caribbean region

Frorm the summary of an upcoming report on the impacts of climate change in the Caribbean region:

The Caribbean will be affected more seriously by SLR [sea level rise] than most areas of the world; SLR in the northern Caribbean may exceed the global average by up to 25%. In addition, the impacts of tropical storms and hurricanes on coastal areas, even at present intensity and frequency, will be compounded by SLR. The impacts of SLR will not be uniform among the CARICOM nations, with some projected to experience severe impacts from a 1 metre SLR. In nations where low lying-land is extensive and who are therefore more exposed to the impacts of SLR and storm surge, concerns are of damage to agriculture, industry and infrastructure as well as salt water penetration into the groundwater reservoirs. For nations with a more complex topography and characterized by steep sloped coasts fronted by only a narrow strip of low lying land, the main concerns are landslides, beach erosion and disruption to infrastructure that is concentrated in limited flat land areas. In both cases, damage to mangroves and seagrass beds is of concern, especially since these areas are of importance in coastal protection as well as fishery resources.

In the case of most of the countries, the tourism industry is of particular concern, since it is preferentially located very close to the coastal, often in low-lying areas with highly erodible sandy beaches. These impacts and changes mean that much more needs to be done in terms of coastal protection and in the planning of coastal development.

It terms of protection, the importance of natural inhibitors to erosion, such as beaches and mangroves, needs to be emphasised. In terms of planning, attention needs to be paid to the location of industry, communication and of course housing. In addition, care will need to be taken in the ‘siting’ of tourist developments, which generally occur close to the coastline. In all these matters, the topographic and geologic setting of locations at risk must be taken into account. The most vulnerable CARICOM nations to SLR were found to be: Suriname, Guyana, The Bahamas, and Belize.

The key impacts of a 1 metre rise in SLR can be summarised as follows: over 2,700 km2of Caribbean land area lost and 10% of The Bahamas land area; with the market value of undeveloped land lost across the CARICOM nations being over US $70 billion. Over 100,000 people will be displaced (8% of the population in Suriname, 5% of The Bahamas, 3% of Belize). The cost to rebuild basic housing, roads and services water, electricity) for displaced population approximately US $1.8 billion. The annual GDP losses will be at least US $1.2 billion (over 6% in Suriname, 5% in The Bahamas, 3% in Guyana and Belize) not including hurricane and storm impacts on GDP. At least 16 multimillion dollar tourism resorts lost, with a replacement cost of over US $1.6 billion and the livelihoods of thousands of employees and communities affected. In addition to the impacts of increased temperature on agricultural yield over 1% agricultural land will be lost, with implications for food supply and rural livelihoods Transportation networks will be severely disrupted: 10% of CARICOM island airports will be lost at a cost of over US $715 million; lands surrounding 14 seaports will be inundated (out of a total of 50) at a cost of over US $320 million, the reconstruction cost of lost roads exceeds US $178 million (6% of road network in Guyana, 4% in Suriname, 2% in The Bahamas).
