Biodiversity: Pros and Cons of Urbanization
It is related to some of the aforementioned threats to wildlife like habitat destruction and pollution. Rising temperatures, melting ice sheets, changes in precipitation patterns, severe droughts , more frequent heat waves , storm intensification, and rising sea levels are some of the effects of climate change. Meanwhile, a warming climate, fluctuating precipitation, and changing weather patterns will impact species ranges. Overall, the effects of climate change increase stress on ecosystems, and species unable to cope with rapidly changing conditions will go extinct. It is estimated that, because of human activities, current species extinction rates are about times greater than the background extinction rate the 'normal' extinction rate that occurs without additional influence.
A UN report assessing global biodiversity extrapolated IUCN data to all species and estimated that 1 million species worldwide could face extinction. Deciding which species to conserve is a function of how close to extinction a species is, whether the species is crucial to the ecosystem it resides in, and how much we care about it. The leatherback sea turtle Dermochelys coriacea is the largest turtle in the world, is the only turtle without a hard shell, and is endangered.
The leatherback sea turtle faces numerous threats including being caught as bycatch , harvest of its eggs, loss of nesting habitats, and marine pollution. Habitat conservation is the practice of protecting a habitat in order to protect the species within it. The latter is often true of species living in biodiversity hotspots , which are areas of the world with an exceptionally high concentration of endemic species species found nowhere else in the world.
Habitat conservation is usually carried out by setting aside protected areas like national parks or nature reserves. Even when an area isn't made into a park or reserve, it can still be monitored and maintained. The red-cockaded woodpecker Picoides borealis is an endangered bird in the southeastern US. Today, it is a rare habitat as fires have become rare and many pine forests have been cut down for agriculture and is commonly found on land occupied by US military bases, where pine forests are kept for military training purposes and occasional bombings also for training set fires that maintain pine savannas.
In an effort to increase woodpecker numbers, artificial cavities essentially birdhouses planted within tree trunks were installed to give woodpeckers a place to live. An active effort is made by the US military and workers to maintain this rare habitat used by red-cockaded woodpeckers. Conservation genetics studies genetic phenomena that impact the conservation of a species.
Most conservation efforts focus on ensuring population growth but genetic diversity also greatly affect species survival. High genetic diversity increases survival because it means greater capacity to adapt to future environmental changes. Though not always the case, certain species are under threat because they have very low genetic diversity. As such, the best conservation action would be to restore their genetic diversity. The Florida panther is a subspecies of puma specifically Puma concolor coryi that resides in the state of Florida and is currently endangered.
In the early s, only a single population with individuals were left. The population had very low genetic diversity, was highly inbred, and suffered from several genetic issues including kinked tails, cardiac defects, and low fertility. The goal was to increase genetic diversity by introducing genes from a different, unrelated puma population. By , the Florida panther population had tripled and offspring between Florida and Texas individuals had higher fertility and less genetic problems. In , the US Fish and Wildlife Service estimated there were adult Florida panthers and in , there were signs that the population's range was expanding within Florida.
Monitoring of wildlife populations is an important part of conservation because it allows managers to gather information about the status of threatened species and to measure the effectiveness of management strategies. Monitoring can be local, regional, or range-wide, and can include one or many distinct populations. Metrics commonly gathered during monitoring include population numbers, geographic distribution, and genetic diversity, although many other metrics may be used. Monitoring methods can be categorized as either "direct" or "indirect". Direct methods rely on directly seeing or hearing the animals, whereas indirect methods rely on "signs" that indicate the animals are present.
For terrestrial vertebrates, common direct monitoring methods include direct observation, mark-recapture , transects , and variable plot surveys. Indirect methods include track stations, fecal counts, food removal, open or closed burrow-opening counts, burrow counts, runaway counts, knockdown cards, snow tracks, or responses to audio calls. For large, terrestrial vertebrates, a popular method is to use camera traps for population estimation along with mark-recapture techniques.
This method has been used successfully with tigers, black bears and numerous other species. Computer vision -based animal individual re-identification methods have been developed to automate such sight-resight calculations. According to the National Wildlife Federation, wildlife conservation in the US gets a majority of its funding through appropriations from the federal budget, annual federal and state grants, and financial efforts from programs such as the Conservation Reserve Program , Wetlands Reserve Program and Wildlife Habitat Incentives Program.
In the late s, as the public became dissatisfied with government environmental conservation efforts, people began supporting private sector conservation efforts which included several non-governmental organizations NGOs. Many NGOs exist to actively promote, or be involved with, wildlife conservation:. From Wikipedia, the free encyclopedia. Practice of protecting wild plant and animal species and their habitats.

Archived from the original on Related to the last point, the land we save , the water we save , and the resources we save, could all be funneled into other uses. Technology is developing and getting better, and may help solve more problems in the future with more investment. Once the technology is perfected it will be indistinguishable in taste and texture from real meat and will be cheaper to produce and purchase. Cultured meat labs and factories might be able to make use of renewable energy in the future.
Lab grown meat can be modified for beneficial reasons, such as healthier and cleaner food options. If we take fat for example, lab grown meat could be produced to contain more omega-3 fatty acids and less harmful fats. The causes of world hunger are political, economical and logistical, and lab grown meat does nothing to change that. Even with food waste , we see that poorer or less developed technologies can find it more difficult to protect produced food between the farm and transport to food markets and supermarkets. Lab grown meat is currently not affordable for everyone, and has high production costs. Currently, the production cost of cultured meat in a lab is expensive compared to the amount of meat it can produce i.
There are other possibly better, cheaper and more effective alternatives regarding food supply for the present and future than putting time and money into lab grown meat. Some argue that moving towards more plant based diets or diets with less meat, dairy and animal products make better use of resources, and are cheaper, more effective, quicker to implement and healthier than what lab grown meat can offer as a food source both in the present and future.
We also already have several plant based meat substitutes on the market such as various types of vegan or vegetarian patties and steaks. If there is concern over GHG emissions and other environmental issues — it makes far more sense to focus on these sectors first, rather than food and agriculture. Having said this — rice paddies that grow in anaerobic conditions or with lots of water are one of the major emitters, and rice is obviously not a meat. Currently, harvesting of animal cells to culture and by using the blood of foetuses from slaughtered pregnant cows as the growth medium, are required to grow lab meat.
So, to mass-produce laboratory-grown meat on an ongoing basis, scientists would need a constant supply of live pigs, cows, chickens and other animals from which to take cells. Lab grown meat is currently no different to growing feed for livestock, which is very inefficient. In both cases, instead of feeding humans directly, resources are being diverted to another food source that will eventually feed humans. The positive impact of livestock agriculture is potentially not talked about enough. Livestock can make use of land that we might not be able to use for crops or other food production, and we are able to get more than just meat from livestock.
We can produce milk, macro- and micronutrients, fibers, hides, skins, fertilizer and fuel; and [livestock] are used for transportation, draft power, a source of income, and a form of banking for millions of smallholder farmers in developing countries. In addition, there are more sustainable and ethical forms of agriculture than the mass intensive CAFCO farms you might hear about in the US. Some sustainable or organic livestock farming may be better environmentally than lab grown meat. There can be a lack of trust between consumers and companies — and rightfully so — people want to keep these companies accountable.
The same trust and accountability issues may face lab grown meat as is currently facing GMO food. There are certain nutrients we may only be able to get in bulk from natural agriculture outside a lab. Some people argue that a diet of vegetables, fruits, grains, beans, nuts and seeds contains all the essential nutrients we need. How do consumers really know what they are getting when they buy different lab grown meat products?
Someone asked me are the nutrients the same in lab grown meat as regular meat as the internal organs are not present to synthesise the nutrients. Is it the same process? Does of mimic the internal organs exactly? Sorry, I disagree with the Cons… red herrings, mostly.

There can be some benefits but also drawbacks to cultured meat.
This number is expected to increase to billions in the coming years. Use of land and water is a sustainability concern we would presumably save a lot of land and water via irrigation and other uses by switching to primarily lab grown meats , and there are pollution concerns to soil , air and water sources from fertilizers, pesticides, manure, greenhouse gases and general degradation of fertile top soil and land Deforestation loss of trees , loss of biodiversity, and land degradation are issues. Animals themselves burp and fart out methane. Would free up space and resources for other uses Related to the last point, the land we save , the water we save , and the resources we save, could all be funneled into other uses.
We would be more efficient and effective. Once the technology is perfected it will be indistinguishable in taste and texture from real meat and will be cheaper to produce and purchase Lab grown meat may be animal origin free in the future If advances can be made with genetic engineering and using plant based materials and cells. They can also control the taste and other features like whether it is boneless.
Lab grown meat adds existing jobs to the economy Lab and factory workers, researchers, scientists etc. These jobs could either add to the economy, or replace existing jobs — or, both. Cultured meat products may be available in some supermarkets soon Some may see this as a pro, and some a con, depending on how they view cultured meat products. Even with food waste , we see that poorer or less developed technologies can find it more difficult to protect produced food between the farm and transport to food markets and supermarkets Lab grown meat has little to do with it. Lab grown meat is currently not affordable for everyone, and has high production costs Currently, the production cost of cultured meat in a lab is expensive compared to the amount of meat it can produce i.
