Democracy, with all its problems, also has its paradoxes.
June 8, Photo: That kind of paradox could give anyone an identity crisis. We seem to think we can take all the goodies out and put all our garbage in, and then expect them to keep happily ticking away indefinitely.
However, while it's true the oceans can provide us with some amazing eco-solutions like alternative energy, they're are undergoing some serious stress factors.
Here are the seven biggest problems, plus some light at the end of the tunnel. Not only does it work towards wiping out a speciesbut also the other species of marine animals that are dependent upon those fish for survival. It's been shown that overfishing can cause marine animals to starvesince we're taking food from their mouths in too large of numbers for them to be able to get their fill.
It is also estimated that most seas already need long term fishing bans if certain species are to recover at all. There is much to be desired in the ways we fish. First, we humans use some pretty destructive methods in how we pull catches, including bottom trawling which destroys sea floor habitat and scoops up many unwanted fish and animals that are tossed aside.
We also pull far too many fish to be sustainable, pushing many species to the point of being listed as threatened and endangered. Reasons for overfishing are obvious in some ways, in that there are a lot of people who like to eat a lot of fish.
The more fish, the more money for the fishermen. However there are other elements at work that promote overfishing that are less obvious, such as promoting the health benefits of one fish over another, or the health of fish oils.
Knowledge of what seafood can be sustainably eaten, whether that is the species of seafood or the method by which it is caught, is a must in order to help keep the ocean's fisheries healthy. It's our job as eaters to question restaurant servers, sushi chefsand seafood purveyors about the sources of their fishand read labels when we buy from store shelves.
Our sustainable seafood slideshows that will show you what you want to look for when you're choosing your next meal, and what to avoid.
But Just for the Fins Overfishing is an issue that extends beyond familiar species like bluefin tuna and orange roughy. It's also a serious issue with sharks. Sharks are killed in the tens of millions each year, mainly for their fins.
It is a common practice to catch sharks, cut off their fins, and toss them back into the ocean where they are left to die. The fins are sold as an ingredient for soup. And the waste is extraordinary.
Sharks are top-of-the-food-chain predators, which means their reproduction rate is slow. Their numbers don't bounce back easily from overfishing. On top of that, their predator status also helps regulate the numbers of other species. When a major predator is take out of the loop, it's usually the case that species lower on the food chain start to overpopulate their habitat, creating a destructive downward spiral of the ecosystem.
The basic science behind acidification is that the ocean absorbs CO2 through natural processes, but at the rate at which we're pumping it into the atmosphere through burning fossil fuels, the ocean's pH balance is dropping to the point where life within the ocean is having trouble coping.
At some point in time, there is a tipping point where the oceans become to acidic to support life that can't quickly adjust. In other words, many species are going to be wiped outfrom shellfish to corals and the fish that depend on them.
A focus on how to protect the coral reefs is important considering coral reefs support a huge amount of small sea life, which in turn supports both larger sea life and peoplenot only for immediate food needs but also economically.
Global warming is a primary cause of coral bleachingbut there are other causes as well. Science is working on waysbut it also is a matter of setting aside marine conservation areas. Figuring out ways to protect this "life support system" is a must for the overall health of the oceans.
Ocean Dead Zones Are Everywhere, and Growing Dead zones are swaths of ocean that don't support life due to a lack of oxygen, and global warming is a prime suspect for what's behind the shifts in ocean behavior that cause dead zones.
The number of dead zones is growing at an alarming ratewith over known to existand the number is expected to grow. Dead zone research underscores the interconnectedness of our planet. It appears that crop biodiversity on land could help prevent dead zones in the ocean by reducing or eliminating the use of fertilizers and pesticides that run off into the open ocean and are part of the cause of dead zones.
Knowing what we dump into the oceans is important in being aware of our role in creating areas of lifelessness in an ecosystem upon which we depend.
Mercury Pollution Going from Coal to Oceans to Fish to Our Dinner Table Pollution is running rampant in the oceans but one of the scariest pollutants is mercury because, well, it ends up on the dinner table.
The worst part is mercury levels in the oceans are predicted to rise.Anne-Laure Delatte argues in “The Crisis of our Crises” that increased tensions in the world are result of weakening and decreased cooperation in the world. This has led adversely to decreased influence of global institutions and cooperative frameworks.
South Africa's student protests have lessons for all universities a surge of xenophobia in the face of the refugee crisis. spread to other campuses, taking different forms. Apr 03, · So the first three flatteners created the new platform for collaboration, and the next six are the new forms of collaboration that flattened the world even more.
Noting that different people refer to, and think of democracy in different ways, (even some despots have called themselves democratic!), Bernard Crick concedes that, We must not leap to the conclusion that there is a “true democracy” which is a natural amalgam of good government as representative government, political justice, equality, liberty, and human rights.
