Proponents for investing in agriculture include Jeffrey Sachs, who argues that wealthy countries should invest in fertilizer and seed for Africas farmers.Imported Ready to Use Therapeutic Food (RUTF) has been used to treat malnutrition in northern Nigeria. Some Nigerians also use soy kunu, a locally sourced and prepared blend consisting of peanut, millet and soybeans.New technology in agricultural production has great potential to combat undernutrition. It makes farming easier, thus improving agricultural yields. By increasing farmers incomes, this could reduce poverty. It would also open up area which farmers could use to diversify crops for household use. The World Bank claims to be part of the solution to malnutrition, asserting that countries can best break the cycle of poverty and malnutrition by building export-led economies, giving them the financial means to buy foodstuffs on the world market. The role of the World Bank cannot be overemphasized in the prevention of malnutrition..

Economics
Many aid groups have found that giving cash assistance (or cash vouchers) is more effective than donating food. Particularly in areas where food is available but unaffordable, giving cash assistance is a cheaper, faster, and more efficient way to deliver help to the hungry. In 2008, the UNs World Food Program, the biggest non-governmental distributor of food, announced that it would begin distributing cash and vouchers instead of food in some areas, which Josette Sheeran, the WFPs executive director, described as a "revolution" in food aid.
Symptoms can appear ten to 30 minutes after ingestion, and include nausea, vomiting, diarrhea, abdominal pain,  tingling or burning lips, gums, tongue, face, neck, arms, legs, and toes. Shortness of breath, dry mouth, a choking feeling, confused or slurred speech, and loss of coordination are also possible. PSP in wild marine mammals
PSP has been implicated as a possible cause of sea otter mortality and morbidity in Alaska, as one of its primary prey items, the butter clam (Saxidomus gigantea) bioaccumulates saxitoxin as a chemical defense mechanism. In addition, ingestion of saxitoxin-containing mackerel has been implicated in the death of humpback whales.Additional cases where PSP was suspected as the cause of death in Mediterranean monk seals (Monachus monachus) in the Mediterranean Sea  have been questioned due to lack of additional testing to rule out other causes of mortality. Detection and treatment
In Vivo, in Vitro, analytical techniques and immunoassays can all be used in order to determine whether saxitoxin is present within shellfish or has been ingested by humans. The most common In Vivo method used is that of mouse bioassays, which provides quantitative and qualitative data regarding the relative toxicity of a suspected PSP infection. An in Vitro method of detection commonly used is that of receptor binding assays which provides similar data to that of mouse bioassays.
