Comparison Between Benjamin Halpern And Andrew Rosenberg

The annual hunt of harp seals (Pagophilus groenlandicus) in Atlantic Canada is contested at the start of nearly every season, with celebrities, politicians, and the public actively weighing in on the matter. Within all of the dialogue and debate, there can be a lot of bias and misrepresentation of facts advocating for or against the seal hunt. Thus, the true sustainable aspects of the industry are drowned out and lost due to the sheer amount of controversy surrounding the issue. Sustainability entails meeting the needs of today without sacrificing the needs of the future (“Sustainable Development” 1). The concept of sustainable resource development involves support pillars that represent economics, society, and the environment. Seal

About 60% of the region’s land is protected7. This includes agricultural land, watersheds, and natural and recreational areas7. These “Green Zones” will limit access and help preserve the region’s natural capital. The David Suzuki Foundation proposed a South Coast Conservation Program in order to “conserve and restore at risk species and ecosystems on the British Columbia South Coast”9.

The MLPA was response to public pressure for more ocean protection. Protecting of natural marine ecosystem services requires that managers find a way maintaining the health of coastal and

Bill Daly’s “Marine Parks” addresses the moral and economic issue of marine parks and whether or not they should stay in business. Daly presents a series of contentions supporting the downfall of marine parks, but there are holes in his argument. His main points/premises being marine mammals can be viewed in the wild for free, tourism is not based around marine parks, and the conditions of the parks are cruel and unnecessary. This essay will address the unclarity in Daly’s arguments and give reasons as to why the arguments he proposed are flawed.

Economic activity and our environment have been closely linked since man first discovered the concept of trade. In the language of economics, the environment has itself, become an increasingly “scarce resource1”. Since economics is about managing these scarce resources, it will be a useful tool when considering some of the environmental issues facing our planet. One of the major concerns confronting the environment today is the overfishing of the world’s oceans, depleting some species to near extinction. With continued advances in technological and industrial proficiency, fishing vessels are able to fish across the globe, further exacerbating the effects of overfishing. Because the oceans are considered a shared or common

The main thesis presented in the essay is whether to allow marine parks to keep marine mammals. The first main argument Bill Daly’s presents is the fact that individuals would rather see marine mammals in the wild life than captured inside a tank. Bill Daly’s states “In fact, there are more places where they can be seen in wild than places where they can be seen in captivity” (Daly 2016, p.469). This argument presents the fact that many of the places people visit have many areas to see marine mammals in the wild, which is an option many tourist would prefer. The second argument presented in the essay is that when it comes to research of marine mammals, marine parks are only useful to study animals that are captured. Bill Daly states “Dolphin

Commercial fisheries can do tremendous damage to the marine ecosystem if they are not managed properly. This became apparent in Newfoundland and Labrador during the 1990s, when decades of overfishing caused the northern cod stocks to collapse and resulted in a moratorium on the centuries-old industry. These were huge ecological and economic losses, which dictated an urgent need to change fisheries policy and practice in a way that would make the industry sustainable and protect marine biodiversity.

In 2009, Dr. Sylvia Earle wrote The World is Blue to educate and alert the reader about human impacts on marine ecosystems. Through this book she conveys her passion and methodical arguments concerning the importance of the conservation of the ocean, which encompasses approximately 80 percent of the earth’s surface. Dr. Earle states “the ocean touches you with every breath you take, every drop of water you drink, every bite you consume” (17). This statement emphasizes the significance of the ocean, not only for marine life, but all life forms on earth. The book implies that currently in today’s world, the conservation of the ocean requires a global effort to reduce human damage from the past generations. Using facts gleaned from credible scientific resources, she defines the problems of overfishing, bycatch, and pollution. By analyzing human impacts on marine ecosystems, Dr. Earle determines successful and unsuccessful solutions to these problems and suggests various ways individuals can change their lifestyles to reduce impact on the environment as a whole.

Our plan of the United States Department of Interior banning all commercial fishing in Marine Protected Areas,and establishing and enforcing regulations for the recreational use of these areas fits to the resolved. The program will be run directly from the government as said from the plan. Our plan will be saving our nation approximately $250 million of discarded fish. The amount of fish we have wasted is breaking down. This plan will help to restore our marine ecosystems so we are able to have another millennia of fish to eat. Our plan also will promote the development of the Earth’s oceans. According to Ocean Conservancy, “Underwater parks, called marine protected areas...allow fish to grow larger, stay healthier, and reach greater abundance and diversity. Fish thrive in these areas...move to other parts of the ocean and replenish weaker populations...We people depend on healthy fish for survival...Underwater parks hold up even in the face of disaster.” our plan of increasing these marine protected areas are crucial if we want to continue to live off of fish meat. Also, Callum Roberts says that Marine protected Areas can “allow recovery of species such as corals, sponges, sea squirts, and mollusks that create complex bottom structures that blind the seabed and perform countless other vital roles such as filtering the water.” the plan of expanding marine protected areas will greatly develop the ocean and its

According to the United Nations, 17% of fish stocks worldwide are currently overexploited; 52% are fully exploited; and 7% are depleted. This means that only an estimated 20% of worldwide fish stocks are not already at or above their capacity(Seafarms, 2013). Catches of Pacific herring have decreased by 71% since the 1960s, with Atlantic herring catches falling by 63%. Atlantic Cod catches have fallen by 69% in the same time(Seafarms, 2013). These are just a few of many facts and statistics on the topic of overfishing. The effects of these statistics and facts impact people’s and animal's lives around the

Clover’s stance on overfishing may seem over dramatic, but Clover’s statement is correct in pointing out that the real danger to the ocean’s wildlife is overfishing. Overfishing is when fish and other sea animal populations are being depleted to the point that sea animals cannot keep up with being fished by reproduction. Fishing massive amounts is degrading the oceans, yet there are both developed and developing countries whose economies rely heavily on fishing.

Seagrasses are essential primary producers that provide habitat and refuge to fauna. Anthropogenic influences have caused global loss of seagrasses and a major contributor is eutrophication, which increases phytoplankton and algal populations, reduces light availability, and causes daily hypoxic conditions. Eutrophication is commonly linked to declines in temperate conditions and is more difficult to link to tropical systems since decreases are typically related to physical damage and diminishing light conditions from runoff. Climate change, herbivore declines, disease and overfishing, along with anthropogenic impacts from coastal development, run-off, eutrophication, and aquaculture have caused declines in coral reefs and mangrove systems. These three systems are interconnected and when one system is impacted, secondary impacts are observed in the other systems; coastal ecosystems will be adversely effected and decline. Additional research, conservation, and ways to reduce anthropogenic impacts have been discussed. Restoration is used to reverse habitat loss, although success is varied. Coastal systems and the biological and ecosystem services they provide, may take decades to establish. Marine Protected Areas (MPAs) are instituted to protect systems from further degradation, restore communities and allow them to flourish naturally. However, local residents are affected by MPAs and may become displaced, have restriction placed on their livelihood, or elimination of their

Marine biologist play a key role in understanding climate change and identifying sustainable and profitable ways humans can use the sea and its resources. Marine biologist understand marine organisms needs in their habitats, ultimately helping protect species and reduce human threats. As experts in understanding marine habitats, marine biologist often form essential parts of relief teams. They respond to oil spills and chemical leaks, helping other scientist restore normalcy to local habitats. Sometimes, marine biologists influence other spheres, such as economics and law. They might analyze the effect of sonar on whales and seals, for instance, recommending best practices for reducing harm on those sensitive populations. Marine biologists understand how the ocean supports basic needs, and in turn relay that information to lawmakers, who establish protocols regarding human use of ocean waters and marine organisms. Marine biologist help develop ocean technology too, improving waste elimination, energy sourcing and extraction of key sources. A brief review of components of the marine environment, world food resources, climate control, air and water quality, transportation, and the ecosystem balance are important features that are studied by marine biology. So, understanding why marine biology is important is foundational to integrating a balanced approach toward management of the sea and proper stewardship of organisms,

However, many fisherman are unable to catch as many fish as they used to, so they are increasingly using cyanide and dynamite in fishing, which further degrades the coral reef ecosystem.[6] This perpetuation of bad habits simply leads to the further decline of coral reefs and therefore perpetuating the problem. One solution to stopping this cycle is to educate the local community about why conservation of marine spaces that include coral reefs is important.[7] Once the local communities understand the personal stakes at risk then they will actually fight to preserve the reefs. Conserving coral reefs has many economic, social, and ecological benefits, not only for the people who live on these islands, but for people throughout the world as well.

In order for there to be plenty of fish in the years ahead, fisheries will have to develop sustainable fisheries and some will have to close. Due to the constant increase in the human population, the oceans have been overfished with a resulting decline of fish crucial to the economy and communities of the world. The control of the world's fisheries is a controversial subject, as they cannot produce enough to satisfy the demand, especially when there aren't enough fish left to breed in healthy ecosystems. Scientists are often in the role of fisheries managers and must regulate the amount of fishing in the oceans, a position not popular with those who have to make a living fishing ever decreasing populations.
