Explanation:

Statement 1 and 2: Producing algae for bio-fuels (excluding simple seaweed production) requires significant capital investments, which may be a significant barrier in developing countries that have a weak investment climate.
Producing biofuels from algae is still in a pre-commercial state of technology development. Most production plants are therefore prototypes, and the development and engineering of such plants requires a high level of expertise.
Statement 3: Algaculture (farming algae) can be initiated on land unsuitable for agriculture or saline water or wastewater.
However, using the land allotted to food crops to algal biofuel reduces the amount of food available for humans, resulting in an increased cost for both the food and the fuel produced. This is an ecological as well as economic concern
