Urban population growth essay

The Future of Protein: Patrick Caughill The technology behind lab-cultured meat products is rapidly advancing. When we start seeing these kinds of products being sold right alongside their traditionally farmed cousins, we should look more at the contentious topic of the impact livestock farming has on the environment.

Further, "each year 13 billion hectares of forest area are lost due to land conversion for agricultural uses as pastures or cropland, for both food and livestock feed crop production.

The National Institute of Environmental Health Science estimates that by livestock populations are expected to double. Animals on factory farms are often confined in poor, overcrowded, conditions and are unable to engage in natural behavior.

This can lead to illness, physical alterations, or even death. Also, to make our meat cheaper by fighting disease and making the animals grow faster, they will be given antibiotic growth promoters.

This has led to the rapid spread of drug-resistant bacteria, also known as superbugs. Scientists believe that the technology will continue to advance rapidly, allowing for products to show up in grocery stores and restaurants within a few years.

Meat growing companies will take self-renewing stem cells from animals and cultivate those in a brewery-like atmosphere. Memphis Meats states that their facilities will be open to the public much like a beer brewery. Lab-grown meats are produced in a much safer, sterile environment than traditional meats.

In addition, lab-grown meats may also have healthier fat content. Diane Cardwell Almost all offshore wind farms currently use fixed platforms built into the seafloor.

While they are increasingly common in Europe, they are just starting in the US, partly due to public opposition. The first such farm is set to begin operation by November near Rhode Island. Enabling wind farms to float over fixed anchors would impact marine life less and add flexibility in where the platforms could be placed.

Proponents say that floating platforms could help overcome some of the obstacles that offshore wind farms face. Developers might receive less opposition from on-shore people if they can locate the farms farther out at sea where they would not be visible from the land. Also their anchoring mechanisms have smaller, more flexible footprints than those of conventional wind turbines, and that could result in less environmental disturbance.

He predicts that floating platforms may come to outnumber fixed-foundation installations. Energy companies, researchers and government officials are planning floating farms adapted from deep-water oil and gas drilling rigs, which use tethers and anchors to moor platforms to the seabed.

That could make deeper waters - like those off the Pacific Coast, around the Hawaiian Islands and in the Great Lakes - accessible for wind-energy development. Statoil, the Norwegian oil and gas giant, is developing what could become the first commercial-scale floating wind farm, off the coast of Scotland, and Seattle-based Trident Winds is pursuing a federal lease to install about turbines more than 30 miles out from Morro Bay on the central California coast.

Despite multimillion-dollar grants from the federal government, cost remains an obstacle. Ocean wind power cannot yet compete with large-scale solar or natural gas.

Floating farms are more expensive to build than land-based ones, and for now, at least, they cost more than fixed offshore installations.

But design advances could drop costs lower than conventional systems. Fixed-foundation turbines require highly specialized equipment, vessels and installation procedures.

Each must be customized to its location, said Irene Rummelhoff, executive vice president for new energy solutions at Statoil.The Population Growth Rate In India Essays - The Population Growth Rate in India For many years concern has been voiced over the seemingly unchecked rate of population growth in India, but the most recent indications are that some success is being achieved in slowing the rate of population growth.
