Why genetically modified GM plants are thought to pose a greater environmental threat then GM animals?
Genetically modified (GM) plants are often considered to pose a greater environmental threat than GM animals due to their potential for widespread and uncontrolled gene flow into wild plant populations, which can lead to unintended ecological consequences. This gene transfer may result in the emergence of "superweeds" resistant to herbicides, disrupting local ecosystems and reducing biodiversity. Additionally, the cultivation of GM plants can lead to monocultures, which diminish habitat diversity and increase vulnerability to pests and diseases. In contrast, GM animals typically have a more contained impact, as they are usually raised in controlled environments and are less likely to interbreed with wild populations.

The bulk of genetically modified organisms used in agriculture are called what?
These are usually called GMOs. An organism that is produced through genetic engineering is considered to be a genetically modified organism (GMO).Insulin-producing bacteria were commercialized in 1982 and genetically modified food has been sold since 1994. Genetic engineering is also called genetic modification.While there is a worry among the public that eating genetically modified food may be harmful but scientific agreement is that these crops are no greater risk to human health than conventional food.
What do you call an organism with spliced DNA?

What is biotech crop?
A biotech crop is one that has been genetically modified to express a desired trait. This may include insertion of a gene(s) that codes for natural pesticide production, increased nutritional value, drought/frost resistance or greater yield.
What are the advantages and disadvantages of frankenfood?
Modifying food crops through genetic methods results in products with remarkable advantages like longer shelf life and resistance to pests when they are grown in the field. The primary motive for genetically engineering food crops is to increase yield. Since this process involves the insertion of foreign genes into wild type crop genomes, the uninformed people in the press have coined the term 'frankenfoods' to describe genetically modified crops. Here are some of the advantages of genetically modified foods: * Greater yield (wheat, rice, tobacco) * Pest resistance (corn) * Longer shelf life (vegetables) * slow ripening of fruits (apples, oranges) * Foods supplemented with essential dietary components - beta carotene rice (golden rice) * Better taste retention (flavr-saver tomatos) and some of the disadvantages: * public acceptance - people approach these genetically engineered foods with a lot of scepticism. Although the scientists who created them are confident about their safety.
The environmental and health risks associated with ground level ozone are greater than the environmental and health risks associated with the depletion of ozone layer?
No, it is false. The environmental risks with depletion if stratospheric ozone are greater.
What is conventional farming?
Conventionally grown is an agriculture term referring to a method of growing edible plants (such as fruit and vegetables) and other products. It is opposite to organic growing methods which attempt to produce without synthetic chemicals (fertilisers, pesticides, antibiotics, hormones) or genetically modified organisms. Conventionally grown products, meanwhile, often use fertilisers and pesticides which allow for higher yield, out of season growth, greater resistance, greater longevity and a generally greater mass.
What is environmental turbulence?
Environmental turbulence refers to the amount of change and complexity in the environment of a company. The greater the amount of change in environmental factors, such as technology and governmental regulations, and/or the greater the number of environmental factors that must be considered, the higher the level of environmental turbulence. For many reasons environmental volatility and instability have been increasing for the past 100 years.
How does temp affect animals?
lower or higher environmental temp than body temp makes the animal's body work harder to maintain body temp (i.e., greater energy expenditure)
What are the risks for environment from genetically modified food?
While some say there are no effects of genetically modified crops on the environment, others believe the following:Crops modified to be resistant to herbicides, such as Round-up, may be causing greater resistance to the herbicide in weeds than occurs when non-GMO crops are grown, either due to the genetic modification being transferred to the weeds or through more pesticides being used.Genetic modification involves taking a gene from one species (such as a bacteria) and inserting it into another species (such as corn or soybeans). In nature, genetic changes occur within species, though in rare occasions, they have been known to occur between similar species. It is not actually known what effects the changes created between species will have on the environment, though some believe this type of breeding could open the door to the modification being passed between species in the environment.Since weeds are becoming resistant to herbicides used on current GMO crops, crops resistant to other types of herbicides are being developed, which leads to greater pollution of the environment.Crops genetically modified to produce a chemical that kills insects when eaten, though claims are made that they only kill targeted insects, may be causing the deaths of non-targeted insects like butterflies and bees.Ultimately, risks to the environment from GMO crops is not known. Genetically modified crops have introduced new variations to genes that would not normally occur in nature. We can only observe changes that may be occurring as a result, and guess at what changes to the environment will ultimately occur.
What do people think of genetically modified food?
Some people believe that GM0 foods are safe and necessary to feed the world. Others believe they are harmful, if not dangerous, to the environment and human and animal health. Still others believe there may be a dark agenda behind them.
What are some ecological concerns that should make genetically modified food illegal?
Though they should not necessarily make GMO foods illegal, the following are some of the concerns that should be addressed:The possibility that growing GMO foods may cause greater weed resistance within a shorter amount of time.Potential harm to soil from the greater amounts of pesticides used on GMO cropsPossible harm to beneficial insects from varieties that are engineered to produce a substance that kills insectsGreater enviromental pollution and higher amounts of pesticides on the foods that are genetically engineeredCross-pollination of GMO varieties with non-GMO varieties that transfers the GMO to non-GMO and organically grown varieties.
Why are small populations difficult to preserve?
The reason small populations is difficult to preserve is because when a small population of animals interbreed, there is a greater risk that harmful genetic conditions can appear in the animals. This is one issue that scientist face when trying to preserve endangered species. One way to lower this risk is to be sure that genetically-similar animals do not breed.
