Rachel Carson Sense of Wonder Contest


The EPA, Generations United, The Dance Exchange, and the Rachel Carson Council Inc. announced their annual poetry, essay, photo and dance contest at the end of this summer. The aim of the contest is to encourage a shared sense of wonder at nature between generations, and so all submissions are to be the work of teams consisting of two or more persons, some older and some younger. The creative work should then express the sense of wonder that the team feels that some aspect of nature evokes within them. Dance entries are a new medium this year and all are encouraged to participate. Voting for winning entries will take place until November First, and you can find out more at www.epa.gov/aging.resources/senseofwonder.

Mechanizing the Machete

For the last five centuries, Brazilian sugar cane has been harvested by hand via the traditional method of field hands setting fire to the brush and then descending upon the harvest with their machetes. This, however, is quickly changing, as more than half of Sao Paulo, Brazil's' largest sugar-producing state, harvested with machines during the 09/10 season. This transition was driven both by increased competition and tougher environmental laws. Brazil is tremendously successful in its sugar cane production, and hopes to further expand its international market, but to do this, it has to keep up with regards to efficiency. In addition, the Brazilian government has instituted new environmental laws that discourage the practice of first burning the fields before harvest. Setting fire to the fields clears out the underbrush and runs out the mice and snakes before workers go in to harvest, but these fires also contribute exorbitant greenhouse emissions and unnecessary air pollution. Moreover, the country wants to be above reproach by other countries for its environmental practices, if it aims to expand its international market.
But there's a downside to all of this. First, one harvesting machine can replace 300 workers, increasing efficiency dramatically, but at the same time putting hundreds of people out of work. And second, the pressures by small farmers to purchase the expensive farming equipment often prove to be too much. The initial investment farmers must make in purchasing a harvester is rather high, and though this is a boon to machine manufactures, many smaller farmers are unable to provide even sufficient collateral.These small farmers, unable to afford the pricey machinery, are forced to enter into partnerships with larger companies, or to search for a new line of work. Furthermore, the government is aiming to completely phase out cane cutting by hand by 2014, making urgent the switch to machinery.
Sucks, doesn't it?

Vampire Killing Spree in Peru

The BBC recently reported 500 attacks and the death of at least four children in communities of the remote parts of Peru due to attacks by rabid vampire bats. Peru's health ministry consequently sent emergency teams to help vaccinate villagers in the area plagued by the rabid bats. Such incidents in the past among vampire bats, at least in the Amazon, have been linked to deforestation for cattle ranching, which has dramatically expanded in the region over the past few decades, as the bats will turn from their usual diet of wildlife as natural habitat is destroyed. The highest toll of these rabid bat attacks in the Amazon was 73 deaths back in 1990.
So, control of the bat population is a bit of an ethical conundrum. We obviously have a problem on our hand because we can't let bats attack people (and I'm sure the experience isn't pleasant, rabid or not). Then again, you can't help but feel bad because it's, in large part, our fault... but so are many things...

A Road Runs Through It


The Tanzanian government is making plans to construct a major commercial highway through Serengeti National Park. The 480 km road would link the Lake Victoria area with eastern Tanzania, bringing, what the government believes will be, essential economic development to the region. The construction of such a highway would link more remote, rural areas to a major road network, allowing transport of people and goods, linking farmers and markets. Sounds pretty good, right? Well, some people don't seem to think so.

The project has met fierce opposition from the tourist industry as well as from environmentalists. Numerous environmental groups oppose the project, not because they feel that progress and development shouldn't take place, but rather because they don't feel that the Serengeti is the best place to do it. See, through this road would allow for a much needed connection between rural communities and commercial centers, at the moment it's serving as a pretty vital ecosystem. The road to be built would bisect the path of the renowned annual "great migration" of wildebeest and zebra, during which millions of animals migrate between the Tanzanian Serengeti and Kenyon Masai Mara in search of fresh water.

Needless to say, a simple memo telling the vast herds of animals that they will need to take a detour from now on probably isn't going to cut it. It also goes without saying that, if this be the case, problems will inevitably result. Possibility number one: there will be parts of the year during which the road will be inoperable for weeks on end due to herds of animals traversing it. And then there's the issue of roadkill in the form of endangered cheetahs (and honestly, I don't think their populations can take even a marginal decrease). Possibility number two: the road cuts the animals off from critical dry season areas. If the latter option comes to fruition, recent calculations show that the wildebeest population, for instance, would likely decline from 1.3 million animals to only 200,000. That's less than a quarter of its current population. Such a decline in numbers could even, according to Andrew Dobson, professor of conservation biology at Princeton, indirectly destroy the region's function as a carbon sink. In fact, even a fifty percent decrease in the wildebeest population would mean less grazing by the animals, increased frequency of fires in the park, and a 180 turn of the ecosystem from carbon sink to a major contributing source of carbon emissions. One could also throw in an inevitable increase in poaching, spread of disease and parasites, as well as the spread of invasive species from the increase in human traffic.

The tourism industry is understandably concerned over the potential loss of thousands of visitors who come to see the great migration. Tourism is Tanzania's biggest source of foreign exchange and a full 50% of Tanzania's tourism dollars comes from Serengeti National Park. Implementation of a highway through the park could lead to the area losing it's status as a world heritage site. The Tanzanian government claims, however, that the road will improve access for tourists.

An alternative southern route has been proposed that would circumvent the park, leave the migration route untouched and would even serve five times as many people as the planned northern road, while fulfilling the same needs for linking regional cities. The alternative route is longer, and therefore a bit more costly, but seems a much better option as it bypasses all of the negative costs associated with the northern road, while increasing the benefits.


Hopefully the Tanzanian government will consider it a viable and worthy front-end investment to build the southern road and leave the zebras alone.

Competition in the Bigger Picture


A former DowAgrosciences employee has been arrested for economical espionage for allegedly passing along to the Chinese government secrets needed to replicate the organically-approved bioinsecticide spinosad (according to the July 26 issue of Chemical and Engineering News). So, I get why this is "economical espionage" and how divulging trade secrets to competitors can hurt your chances in the global marketplace, yadda yadda yadda. What I don't like is that we can't think bigger than that. Sure our chances are better on a playing field tipped in our favor, but in this case a level playing field makes organic food production more feasible and accessible to one of the world's largest and most populated countries. Human society may recognize political borders, but biology doesn't, and encouraging organic agricultural methods seems a surefire way to make positive environmental impacts in a nation with the most mouths to feed.

I understand the illegality of the situation, but lament that it has to be so.

Russian Government protects Korean Pine


The Russian government has recently introduced new measures to protect the Korean pine, in honor of World Tiger Day (July 29th). So what does a pine tree have to do with tigers? Well, though the pine isn't necessarily endangered itself, the demand for the tree for lumber has increased substantially, and the tree is a key species found in the habitat of the Amur tiger of Eastern Russia. So, the government placed the Korean pine on the CITES list, which requires harvesters to have a permit to export the wood. Protecting the tree greatly preserves the habitat that it shares with the endangered tiger. Great round-about way of furthering the tiger's interests, if you ask me. :)
