There are many benefits to seaweed farming. It is environmentally friendly and does not require chemical fertilizers or pesticides. In addition, seaweed farming can help to mitigate climate change by sequestering carbon dioxide from the atmosphere.Seaweed farmers can sell their crops to restaurants, markets, or processors for use in cosmetics, fertilizers, and animal feed. Prices for seaweed vary depending on the market demand and type of seaweed, but it is typically more profitable than traditional crops such as rice or wheat. Seaweeds pull more of the greenhouse gas from the water than all three combined based on biomass. That means seaweed farms can help to combat local impacts of ocean acidification. The potential loss of benthic habitat to equipment such as anchors that are needed to establish seaweed farms and the possibility of marine mammals and other large species becoming entangled in the lines. Seaweed absorbs CO2 more effectively than treesand it's estimated that it stores around 175 million tonnes of carbon each year that’s equal to 10% of the world's car emissions.

Growing seaweed on a global scale also has ecological risks; too much seaweed could impact the amount of light that goes down to other species affecting photosynthesis processes and could have dangerous effects on ecosystems by removing too many nutrients from wild ecosystems. Seaweed farmers, many of whom are women, face a number of environmental, social and economic challenges. These include climate change, weak representation of women producers, difficulties in accessing international markets and insufficient protection of coastal ecosystems. However, inorganic arsenic is known to increase the risk of cancer, and some seaweed species can contain high levels. Eutrophication due to human sewage rich in phosphate and nitrate from major municipalities and small towns has negative impacts on seaweed growth. Run-off from land-based agriculture, thermal power plants and chemical factories inundates near-shore waters and contributes to commercial cultivation challenges. Seaweed is a crop that scientists believe can help to effectively reverse the climate crisis. A 2019 study found it 20 times more effective than plants at carbon sequestration: taking CO2 from the atmosphere and “locking” it up in solid or liquid form. Seaweed farming is a simple and eco-friendly approach for sustainable development. Because of relatively small expenditure required to set up seaweed farming, marine algae farming is a viable option for coastal developed countries to help mitigate climate change concerns. Based on the current selling price of $ 0.50 per kg of dried seaweed, if you are engaged in a 320 line farm, you can expect to earn about $ 60.00 per week. If you have a bigger farm, let's say 480 line farms, you can earn up to $ 90.00 per week. This means $ 15.00 to $ 22.50 per each of the four working days. Seaweed absorbs CO2 more effectively than trees and it's estimated that it stores around 175 million tonnes of carbon each year –that's equal to 10% of the world's car emissions. Seaweed could play a vital role in the sustainable future of our planet; it has a low carbon footprint, doesn't require fresh water, needs minimal land-based infrastructure, and can be used in a number of industries aside from food, including agriculture, cosmetics and pharmaceuticals, and as a biofuel.

Seaweed farming can be profitable. Seaweed farmers can sell their crops to restaurants, markets, or processors for use in cosmetics, fertilizers, and animal feed. Prices for seaweed vary depending on the market demand and type of seaweed, but it is typically more profitable than traditional crops such as rice or wheat. The Indian government plans to invest about 86.8 million USD in seaweed production. The government aims to increase seaweed production to 1 million tons annually by 2025. Seaweeds are a source for many important applications and the demand for the biomass is growing rapidly. Wheatgrass instead of Seaweed: Extensively popular in the west as a super food which has a complete range of vitamins from A to vitamin K, along with iron, antioxidants benefits, sea wood would find a tough competition in India from wheatgrass which is locally produced and has almost the same nutrition profile as seaweed. Pollution in the marine environment can be taken up by the growing seaweeds, rendering them potentially unsafe for food and feed applications. This risk is recognized by all respondents. Seaweed production has been linked to a slew of negative outcomes. These include “crop-to-wild” gene flow, disease, parasite, and alien species habitat provisioning impact on planktonic, epi- and mega fauna species. Rising sea surface temperatures (SST) due to climate change inhibits the growth of seaweed species. Monsoonal periods in India are associated with occasional occurrence of cyclones and create high seawater turbulence and high tidal fluctuations. Seaweed farming can be profitable. Seaweed farmers can sell their crops to restaurants, markets, or processors for use in cosmetics, fertilizers, and animal feed. Prices for seaweed vary depending on the market demand and type of seaweed, but it is typically more profitable than traditional crops. Seaweed absorbs CO2 more effectively than treesand it's estimated that it stores around 175 million tonnes of carbon each year that's equal to 10% of the world's car emissions. Microalgae underpin the food chain, providing an essential source of food for molluscs, young fish and crustaceans. Seaweeds also provide an important habitat. Species such as kelps can form vast forests, offering shelter for many species to spawn and providing nursery grounds for juveniles. Seaweed farms absorb nutrients and carbon dioxide to grow. The farms can help improve water quality and buffer the effects of ocean acidification in surrounding areas.
